Soft Drink Production: The Role of Material Handling Equipment

Material Processing in Soda - Manufacturing Equipment

Authors: Sarah Wagner and Hunter Kloes

Long before the soda industry brought us drinks as a refreshment, pharmacists prescribed “soda pop” to patients. Initially, pharmacists served carbonated water at the pharmaceutical counter to patients for medicinal purposes. Soft drinks were not limited to the medical industry, however. They were also commonly accepted to drink with dinner.

By 1820, flavoring was added to carbonated beverages – from salt to ginger. In 1830, soft drink producers started adding lemon; by 1858, they added tonic. Yet, it wasn’t until 1886 that John Pemberton, a pharmacist in Atlanta, Georgia, invented the first cola drink.

John Pemberton was a chemist and druggist before serving in the Civil War. During the war, Pemberton suffered a major wound and became dangerously addicted to the pain reliever morphine. To defeat his dependency on morphine, Pemberton created Coca-Cola. He heard another doctor used coca (cocaine) to cure opium habits; Pemberton combined the coca leaves with kola nuts. His bookkeeper convinced him to call it “Coca-Cola.” Nearly 140 years later, soft drinks make up over a $430 billion industry. (Grand View Research)

Steps in Soft Drink Production

Water Treatment. Flocculation is the process where solids form larger clusters, or flocs, for removal from water. Aluminum sulfate and ferric chloride are examples of what’s pulled. Monochloramine is used to kill germs, yet it is still safe to drink.
Extraction of Raw Goods. Raw materials for producing goods and services may include vanilla bean, apricot seed, and lemon. An example of extraction used in soft drinks is the brand, Dr. Pepper. It contains extract of cherry, licorice, amaretto, almond, vanilla, blackberry, apricot, caramel, pepper, anise, sarsaparilla, ginger, molasses, lemon, plum, orange, nutmeg, cardamom, allspice, coriander juniper, birch, and prickly ash. Whew!
Sugar or High Fructose Corn Syrup (HFCS) Handling. Sugar is extracted from beets, corn, and cane. Raw goods are then mixed with the sugar sludge. The concentrate is typically made at the soft drink plant headquarters using a variety of ingredients like those listed above.

The Role of Material Handling Equipment
in Soft Drink Production

Soda production is a complex process requiring sophisticated material-handling equipment to ensure efficient processing and production. To produce high-quality soda, raw materials such as sugar, yeast, and water must be loaded into equipment designed to manage the ingredients for further processing. This includes specialized machines for weighing, blending, and pasteurizing the ingredients in a precise manner.

Then, additional soda manufacturing equipment is needed to move the processed material from one station to another within the facility. For instance, conveyors are often used during storing and transporting bulk materials like sugar that need to be directed onto other processing equipment with little manual labor involved. Robotic arms are also commonly used to automate assembly lines, while pallet jacks can help streamline loading processes at different stages of production.

Sanitary Design in Soda Manufacturing

The importance of sanitary equipment design in soda manufacturing cannot be overstated. The demand for safe food and beverage products has never been greater, and sanitary equipment is essential to meet these requirements. Sanitary equipment design involves using materials, components, and methods that eliminate contamination risks during production. This includes using hygienic surfaces, minimized crevices, effective drainage systems, and avoiding cross-contamination between different production steps.

Choosing the Right Soda Production Manufacturing Equipment

Quality control protocols must be implemented when choosing soda production and manufacturing equipment to ensure all materials used meet health standards and minimize potential hazards associated with the production process itself. In addition, all components should be easy to clean and maintain while being corrosion-resistant from any liquid or chemicals used during the manufacturing process.

When it comes to soda manufacturing, there is no room for shortcuts. The selection of the right soft drink manufacturing equipment is essential in ensuring a safe, efficient, and profitable operation.

Are There Risks of Using Wood Pellets in Manufacturing?

by Maria Buss and Will Aldrin

As the world looks for ways to become more environmentally friendly, many industries are turning to renewable energy sources. Manufacturing is one of them.

In recent years, there has been a growing interest in using renewable energy sources in manufacturing. One of the most promising renewable energy sources is wood pellets in manufacturing. Wood pellets are a type of biomass used to create heat and power. Manufacturing plants that use wood pellets can reduce their emissions of greenhouse gases and other pollutants. In addition, there are other advantages of wood pellets being used in manufacturing.

Wood pellets are biomass, a renewable resource, so they can help reduce dependence on fossil fuels.
Wood pellets are relatively inexpensive and easy to transport.
Wood pellets have a high energy density and can create a lot of power without taking up much space.

However, there are some disadvantages of wood pellets being used in manufacturing, and if you’re a wood pellet manufacturer, or a manufacturer using wood pellets as an energy source, here are some things you should know.

Wood pellets as an alternative fuel source for manufacturing

Challenges for Wood Pellet Manufacturers

As a renewable and sustainable energy source, wood pellets in manufacturing have been gaining popularity in recent years. But there is a downside to this otherwise environmentally friendly fuel: it can damage manufacturing equipment.

Wood pellets are made by compressing sawdust into small, hard nuggets. This process creates a lot of heat and friction, which can cause wear and tear on equipment. In addition, the high pressure needed to compress the sawdust can result in corrosion and other problems for manufacturing equipment. Therefore, the equipment used must be designed to sustain these especially harsh conditions.

Sawdust is very fine, sometimes almost like a powder, and there can be challenges from plugging and buildup. As with any manufacturing that involves powder, special considerations need to be made when handling wood pellets. Otherwise, particles can easily get trapped in the nooks and crannies of equipment, causing equipment damage and potentially becoming airborne, contaminating the air.

Disadvantages of Wood Pellets Being Used in Manufacturing as An Energy Source

While there are several advantages of wood pellets being used as a fuel source, manufacturers must be aware of the potential for damage to their equipment. Proper maintenance and care can help minimize the risk of problems, but it’s important to be aware of the potential issues before switching to wood pellets.

Wood pellets can be difficult to store and handle.
Wood pellets are made from compressed sawdust and other wood waste products, creating powder-like dust. The dust from the pellets can build up on surfaces and eventually cause problems with the equipment.

HaF Equipment’s H-Series is ideal for manufacturers using wood pellets as an energy source and for wood pellet manufacturers.

The H-Series is high-quality pre-engineered equipment. This line of Ready-To-Go equipment features “Tool-Free Quick Take-Apart” which is designed for dependability, efficiency, and the capability for it to be easy to clean.

Material Handling Challenges When Handling Salt

By: Caleb Meyer and Caroline Harrington

Every day people use salt, and most people associate salt with baking or cooking at home. Perhaps they associate it with deicing roads during an icy winter if they live in colder climates. However, in manufacturing, we associate salt with bulk processing and its importance to industries ranging from food manufacturing, animal feeding, pharmaceuticals, chlorine production, textiles, and oil.

Salt is a common ingredient in many industrial and manufacturing processes but can be corrosive to machinery. When salt comes into contact with metal, it causes the metal to oxidize, leading to rust and other damage. Moisture accelerates this process and is particularly damaging to machinery used in wet or humid environments. Over time, salt corrosion causes parts to break down and fail, leading to costly repairs, replacements, and downtime! To prevent salt damage, regularly cleaning and lubricating machinery is necessary to remove salt from work areas as soon as possible to extend the life of the manufacturing equipment and avoid loss of revenue.

Use of Salt in Manufacturing

Salt handling in manufacturing is not uncommon, and interestingly, the decision to use salt is made based on how its chemical structure will interact with the materials used. For example, salt interacts with water to lower its freezing point. When used on roads, it results in safer roads. Salt is also used to prepare textiles before dying, in oil drilling as a lubricant and cooling agent for the drilling head. Of course, everyone knows that salt is a common ingredient in baking and cooking to add flavor to our favorite foods and desserts! However, there are material handling challenges when it comes to salt in manufacturing. When used extensively, salt breaks down the oxide film of metals resulting in pitting. Its abrasive nature also wears away at materials and tends to clump up in humid environments presenting a material handling challenge.

Material Handing Challenges in Production When Using Salt

Salt is formed from the reaction of an acid and a base to create an ionic salt and water. In its solid-state, salt forms crystals in the face-centered cubic close packing atomic crystal packing structure. This arrangement allows the salt to be a good conductor of electrical current. When salt is dissolved in water, the positively and negatively charged ions dissociate to create a brine. When the brine is in contact with iron-rich metals it not only puts oxygen atoms in close contact with the metal but also provides an ideal environment for free electrons in the iron structure to bind with the oxygen resulting in the formation of rust and eventual corrosion.

What Manufacturers Should Know When Handling Salt

From a material handling equipment manufacturer’s point of view, we know the destructive nature of salt on equipment; poorly made and maintained equipment allows that destruction to escalate. Salt can quickly wear manufacturing equipment down and ruin products when mismanaged—understanding the frustrations and challenges of the manufacturing industry drives HaF Equipment to design solutions to material handling systems that can handle related material handling problems when using salt in manufacturing. At HaF Equipment, we address salt’s corrosive and abrasive nature in our designs by:

using the best choice of stainless steel for all equipment.
designing tool-free-take-apart equipment that’s easy to clean
designing to minimize nooks, crannies, and crevices where corrosive materials can lodge.
keeping the system dry

In a process where ambient humidity will ruin the product, HaF can integrate a dehumidifier and design all welds in either food grade or USDA grade standards when necessary. HaF also incorporates a series of pistons as flow enhancement tools to blow cool, dry air over the salt to reduce ambient humidity and uses pneumatic thumpers to break up clumps so that they will not form due to settling.

HaF has the expertise and experience to accommodate a wide range of needs when it comes to the material handling of strong chlorides such as salt. We’re Ready to Connect with you and offer a customized solution and discuss your specific project needs.

Flour Production: Material Handling

by Will Aldrin And Spencer Evans

Flour is an important ingredient in baked goods, pasta, and many other foods, and wheat flour is one of the most universal ingredients used in food production worldwide. In 2018, of the approximately 765 million tons of wheat crop, 53% (or 402 million tons) were used to make wheat flour. More wheat flour was produced than sugar (166 million tons), salt (290 million tons), and soybeans (349 million tons).

The flour-making process is fairly simple; however, the flour production process on a large scale is complex and labor-intensive, and proper material handling of flour is a critical part of successfully processing flour for commercial use. An efficient flour handling system will help to reduce production costs and improve product quality. Flour production best practices include:

Easy to clean equipment: The use of material handling equipment that is designed with minimal crevices and grooves and can easily be cleaned
Automation: The use of material handling equipment with sensors and automation to control the flow of material
Implementing strict cleanliness protocols
Safety: Design systems that are safe and train employees in safe lifting and moving techniques

EASY-TO-CLEAN EQUIPMENT IS CRITICAL!

What do you mean flour is raw?!

This might surprise some of you, but all that flour is a raw ingredient. Flour isn’t “raw” because it is a product component the way sand is the “raw” ingredient of glass. Flour is “raw” in the same way that uncooked meat and poultry are “raw.” Flour is minimally processed during its creation, meaning there is still lots of bacteria in the flour, even in the bags you buy at a grocery store. None of that matters once the flour is used, as many applications of flour heat the flour to the point where most, if not all, of the bacteria are killed. But this means that the flour is highly susceptible to spoiling if not properly stored.

To make sure that flour successfully goes from field to food, there are a variety of important requirements that must be met so that the flour is moved and stored in a safe and sanitary manner.

Flour handling systems equipment needs to be cleaned regularly. The HaF Moovinator is a filter receiver that is designed in a pneumatic conveying system to be easy to clean. Below is an image of the HaF Moovinator. When the filter bag access door is opened, there is easy access and a good “line of sight” for the operator to clean out the equipment.

Safety and Sanitary Measures When Handling Flour

Considering humidity levels is one of the most important factors when storing or moving flour. Bacteria such as salmonella and E. coli can quickly propagate in flour when exposed to even mildly humid air. That’s why dehumidifiers and airtight storage are necessary when storing flour for commercial food processing, especially in tropical climates near the equator. Humidity can also cause the flour to clump, leading to difficulty transporting it through pneumatic systems and improper mixing when producing products where flour is used.

When designing a flour handling system, several things must be considered.
1. The construction materials and the equipment’s sanitary design level. Stainless steel and food-grade construction are critically important.
2. The flour equipment build must be checked to ensure no pits, crevices, or holes where material can stagnate, spoil, and infect the rest of the flour. This includes checking for airtightness on flour storage equipment. Imperfections will allow humid air to enter the system, raising the chance of bacteria growth in the flour.
In a facility that handles bulk flour production, there are many elements present for a dust explosion or fire to occur: fuel, confinement, dispersion, oxygen, and a spark. An effective and properly operating industrial dust collector and dust collection system minimizes the risk of fire or explosion and must be considered when designing a flour handling system.

Summary:
Proper flour material handling is a critical part of a successful flour production process for commercial use, and an efficient material handling system will help to reduce production costs and improve product quality. Commercial manufacturers can help protect the consumer, their output levels, and ultimately their bottom line by investing in high-quality flour processing equipment.

HaF Equipment specializes in the design and supply of flour processing systems, focusing on the details of sanitary design. We call it “tool-free-quick-take-apart” equipment. Our flour handling systems can also incorporate explosion mitigation equipment.

Is Your Industrial Dust Collector Equipment Sufficient?

Industrial Dust Collector The Right Equipment

Is the industrial dust collector for your dust collection system efficient enough to handle the needs of your business manufacturing and material handling systems? Dust is a common byproduct of industrial processes and can present a serious health and safety hazard if not properly controlled. Dust can also be explosive! Great care in the design and supply of industrial dust collection systems needs to be taken, and the right industrial dust collector equipment is a critical part of that system. Dust particles can be breathed in, causing respiratory problems, or they can accumulate on surfaces and create slip-and-fall hazards. In addition, dust can interfere with the proper functioning of equipment, leading to production downtime.

An industrial dust collector is a device that helps to control industrial dust. It works by capturing dust particles from the air and then either storing them or disposing of them. There are many different types of industrial dust collectors available, and the best type for a particular application will depend on the nature of the dust and the industrial process. For example, cyclonic separators are often used for heavy-duty applications such as sawdust removal, while baghouses are better suited for capturing fine particles. Proper industrial dust collection is essential for maintaining a safe and productive workplace.

HaF Equipment manufactures some of the most reliable and affordable industrial dust collectors on the market. Our factory dust collectors are designed to meet the specific needs of your workplace, and our team is always available to help you choose the right model for your needs. HaF Equipment has the perfect solution for you whether you need a small, portable unit or a larger machine for your particular industrial dust collection needs.

Read about the different types of industrial dust collectors that HaF supplies in our article, Industrial Dust Collection: Why The Right Equipment Matters.

Typical material handling equipment that require dust collection control:

Bulk Bag Filler

A Bulk Bag Filler is a standard piece of equipment in manufacturing. It is used to package a wide range of dry powders and granulated and flaked materials into bulk bags (also known as totes, super sacks, or big bags). They are engineered for bulk material processing and packaging applications requiring high-performance operation, where reliable and repeatable duty cycles, rates, accuracy, and equipment effectiveness are crucial. They can be designed to operate as either manual or automated systems.

Using HaF Bulk Bag Fillers, the operator loads a bag into the filler station and inflates the inflatable boot, creating a seal to hold the bag in place for filling. The filler head is equipped with a vacuum port connected to a dust collection system (such as the systems that HaF supplies!) and is used to pull out the dust created while filling. Inside the filler head, an internal baffle goes below the vacuum port, causing the product to fall into the bag while forcing the air to make a 180 turn. This pulls the air out of the bag without pulling any product.

Portable Dust Collector - HaF Eqiupment — Portable Dust Collector – HaF Equipment

Truck Unload Systems

Unloading a semi-trailer of raw ingredients into a storage silo is another process that requires dust collection. The semi-trailer often comes equipped with an onboard positive displacement blower package that pressure-conveys product into the silo. Because both product and air are being blown into the silo, a lot of dust is created and needs to be pulled out of the system.

HaF has designed an operator-friendly bin vent that is used on top of the silo to create an effective filtration point where powder stays in the system and clean air exits the bin vent. The bin vent is a dust collection apparatus because it is used to cleanly release the air from within the silo back into the atmosphere. This is achieved by using filters that stop the product from leaving as the air escapes. The bin vents are sometimes equipped with a fan mount. This allows a fan to be added later for applications where air needs to escape faster. This system keeps the dust from escaping out of the top of the silo. Once an unload cycle is complete, the filter bags are back pulsed with compressed air to keep them clean and clear of dust. System Integration Unloading and Silo Systems.

Bulk Bag Unloaders

Bulk Bag Unloaders are used to unload product from super sacks (also known as big bags or totes) into the system. Untying a bulk bag can be a dusty process for operators, and like the bulk bag filler, it is important to contain the dust so that it does not enter the plant or the atmosphere. The bulk bag unloader has either a receptor tube or a discharge spout with a glovebox for operator access. Which type depends on the application and customer preference. Again, like the bulk bag filler, this is equipped with a vacuum port connected to a central dust collection system that HaF can design and supply. The HaF Dust Collection System is used to pull out the dust created when the operator has the door open. There needs to be a slight draft so that powder does not fly into the face of the operator. HaF has included a custom-designed baffle to prevent the product and the bag from being pulled in. The dust collection system is activated when the operator opens the door and disengages the safety sensor on the discharge spout. It turns off when the door is closed so that product can resume flowing. In this way, HaF has automated the dust collection process to ensure a clean environment for operators.

Bag Break Stations

To add 50-lb bags of material into the system, operators use Bag Break Stations. Bag Break Stations require effective dust collection when the operator is opening bags. HaF has designed the bag break stations to work with dust collection systems so that a slight vacuum is pulled to prevent dusting while operators empty bags into the hopper. Once the operator closes the door, the dust collection system stops, and the filter bags are pulsed to remain clean and clear of dust.

Summary:

Dust collection is a critical step in the manufacturing process. By collecting dust before it has a chance to enter the atmosphere, factory dust collection systems help to keep the air clean and safe to breathe. In addition, dust collection systems help prevent the spread of dust particles throughout the factory, which can lead to equipment malfunctions, production delays, and, worse, plant explosions. By investing in high-quality dust collection systems, manufacturers can help protect their workers and their bottom line

Turnkey Manufacturing Solutions

HaF Bulk Material Handling Equipment Manufacturer

by Morgan Bocci and Ana Meemken

Turnkey manufacturing is a process where one company oversees all aspects of a project’s production from beginning to end. A turnkey project takes the inconvenience and stress away from the customer by using a sole entity to coordinate, manage, and facilitate a project from detailed engineering to system installation and start-up. The responsibility of finding installation contractors, defining installation scope, managing installation, and coordinating various trades is taken off the customer.

FINDING AN EXPERIENCED TURNKEY VENDOR

One of the biggest advantages of utilizing turnkey manufacturing service is that the customer is able to purchase a system and sit back and wait for the finished project. When the full scope of the project is complete, the customer can turn the keys and start-up that system. It is important to choose vendors with experience in this type of service so that a successful finished project and a smooth transition can be achieved.

Choosing an experienced turnkey partner gives customers the ability to go into a project with a high level of confidence. The risks of system responsibility are mitigated as experienced partners know what to expect and how to effectively deliver a complete system.

TURNKEY PROJECT ADVANTAGES AND DISADVANTAGES

It is important for the customer to consider all the turnkey project advantages and disadvantages of collaborating with a vendor. The greatest advantage is that there is one single point of accountability. The customer only needs to communicate with one vendor; therefore, there is no need to coordinate with multiple vendors across various service lines. Should the project need additional work to be included, your vendor will bid and facilitate the needed contractors. The benefit of the vendor handling the additional resources is that the risk is on them. The customer does not need to take the time to research additional help, nor do they have to worry about the credibility of additional vendors. When a turnkey vendor is handling the project, the timeline runs more smoothly. The vendor will align schedules and keep the project moving.

The advantages outweigh the disadvantages of turnkey; however, it is important to be aware of the cons that are involved. The main concern with turnkey projects is establishing communication. It is vital to the success of the project that both the customer and the vendor are clear on expectations. Customers can feel removed and uninformed of the status of the project if the vendor is not staying in contact with them. There can also be hesitations from the customer that there will be additional charges if the turnkey vendor experiences unexpected work that needs to be added to the project.

Summary

HaF Equipment offers turnkey manufacturing services and solutions for projects big and small. Our team understands the concerns of our customers and takes the time to listen. We develop a plan and communicate along the way. If you need someone you can trust and want to eliminate the stress of managing all the details of your next project, HaF is Ready To Connect.

Industrial Dust Collection: Why The Right Equipment Matters

by Becca Hansen and Kim Selle

Industrial dust collection system in manufacturing is vital to workplace safety. In 2021, there were 51 dust-related fires worldwide, resulting in five injuries. Twenty-five (25) of these fires were in food production facilities. Much like the severity of fires, explosion mitigation is a top concern. In 2021, there were twenty-eight (28) dust-related explosions worldwide, resulting in 39 injuries and 8 fatalities, 10 of which were food product-related. In a facility, there are many elements present for a dust explosion or fire to occur: fuel, confinement, dispersion, oxygen, and a spark. An effective and properly operating industrial dust collector and dust collection system minimizes the risk of fire or explosion.

In addition to fire and explosion prevention, there are several other reasons to incorporate industrial dust collection and the right industrial dust collector into manufacturing systems. In the United States, OSHA requires dust control in indoor workplaces to comply with legal limits for each ingredient and material. Additionally, effective dust collection and control assists with eliminating cross-contamination of food or other materials; control of health hazards, including bacteria, allergens, and, yes, insect parts. It can also assist with efficiency and recycling or reuse of food scraps, food-grade material, or pet food. Having an industrial dust collection system creates an overall cleaner work environment by keeping dust and particles from getting into the air and keeping it away from the operator.

Depending on the industry and application, the dust properties will affect which industrial dust collection equipment is best. Some of these properties include:

Particle size (small or large)
Bulk density (loose or compact)
Composition (acidic or basic)
Temperature (room temperature or elevated)
Moisture level (low or high)

Selecting the correct industrial dust control equipment to handle the dust is critical and will depend on the product and its handling in the system.

Dust Collection Methodologies

HaF Equipment offers custom design dust collection systems in any of our three general methodologies:

Dry Dust Collection
Wet Dust Collection
Portable Dust Collection

Dry Dust Collection

HaF utilizes envelope-style filter bags to provide maximum filter area in a small space, This accommodates the custom-sized airflow for the application, and the dry dust collector captures dust particles on the filter bags.

With HaF’s reverse jet pulse cleaning system, the filter bags drop dust into a hopper that can be manually or automatically removed.

Wet Dust Collection

Our wet dust collector utilizes a turbulent zone of water to capture dust particles. This method is a great way to eliminate explosion mitigation equipment, and it is easily cleaned with an optional Clean In Place (CIP) design. The dusty water discharges with either a manual process or automated valving. Wet dust collection also removes the requirement of filter bags altogether.

Portable Dust Collection

A portable dust collector allows the operator flexibility to move the dry dust collector to the point of use. Our portable dust collector comes with many customizable features including dust removal systems.

Pick-up points can be designed for each method including custom hood designs. We then size the ductwork and corresponding exhaust fan for an exact fit.

Dust Hoods are used in applications where a customer might want to squish the air out of a bag before entering the bag sealing process. There is an overhanging open duct in this application where a vacuum is being pulled. Dust hoods can also be used over conveyors to prevent dust from being spread throughout the plant.

Summary:
Dust collection is a critical step in the manufacturing process. By collecting dust before it has a chance to enter the atmosphere, dust collection systems help to keep the air clean and safe to breathe. In addition, dust collection systems help to prevent the spread of dust particles throughout the factory, which can lead to equipment malfunctions, production delays, and worse, plant explosions. By investing in high-quality dust collection systems, manufacturers can help to protect both their workers and their bottom line.

HaF Equipment is here to assist you with which dust collection application and equipment would benefit your business.

The Role of Technology to Combat Air Pollution

When most people think about air pollution, they envision smog-filled cities or factories belching out black smoke. While these are certainly significant sources of pollution, there are actually many sources of air pollution, both natural and man-made. Air pollution was primarily seen as an unavoidable by-product of human activity in the past. However, as our understanding of the effects has grown, so has our ability to combat air pollution. HaF Equipment is dedicated to utilizing sound technology to continue the fight against air pollution with specially designed equipment and design solutions like those identified below.

Dry Sorbent Injection (DSI) systems removes acid gases like SO2, HCI and SO3 from an exhaust stream that is found in fuel combustion processes. DSI systems are ideal for air emissions regulatory compliance requirements for a variety of reasons:

DSI is the lowest capital cost solution
DSI has the smallest footprint, and
DSI has the most flexible installation needs.

Commonalities in DSI systems are pressure conveying system, rotary feeders, splitters, and lances.

Baghouses accommodate a large range of particulate sizes and outlet emission targets. Because of our extensive design capabilities, we can also design baghouses for a variety of temperatures. And our designs are proven to limit stressful burdens on bags, which reduces the risk of broken bag incidences.

Baghouses can also be used in conjunction with our DSI systems. This improves acid gas removal efficiency by taking advantage of a filter cake built up on the baghouse filter media.

Computational Fluid Dynamics Technology (CFD modeling) is an analytical tool that can be used to predict airflow and particulate behavior in a flue gas duct. CFD modeling can be used to identify high-impact areas of optimization in the process of combating air pollution.

Pneumatic conveying. HaF Equipment has solutions for ash handling: vacuum conveying, pressure conveying and mechanical conveying. Each conveying method can be achieved using a variety of products that we can customize to a specific need; even those that are dependent on conveying distance, ash loading, and temperature profiles.

Airlocks and Pneumatic Conveying

by Dan Fried and Devon DeJong

Does your mind go straight to the scene of your favorite Sci-Fi movie when someone mentions airlock systems– where the hero (or villain) is trapped between safety and being sucked out into deep space at the press of a button? We like a good science fiction movie, too, but airlocks in pneumatic conveying get us just as excited!

An airlock is a compartment with doors that can be sealed against pressure which permits the passage of people and objects between environments of differing pressure or atmospheric composition while minimizing the change of pressure in the adjoining spaces and mixing of environments. The airlock technology consists of a relatively small chamber with two airtight doors in series which do not open simultaneously. (Source)

In pneumatic conveying, airlock systems are the passageways that bulk materials use to move between environments consisting of different pressures, gases, or both, with the goal being to minimize pressure loss and to prevent the gases from mixing. (In pneumatic conveying, airlocks are used for passage between various environments of different materials like gases, or different pressures, or both, to minimize pressure loss or prevent the gases from mixing). Airlocks are a critical component of pneumatic conveying designs. When applied to conveying, the objective is to move bulk material across a pressure differential; low to high (Pressure Conveying) or high to low (Vacuum Conveying).

How airlock technology works can sound complex; however, the design is simple. When a product drops into a pocket on the top, the rotor spins and drops the product out the bottom. The rotor has VERY tight tolerances with the housing to prevent air or the product from blowing past the rotor tips. (A typical airlock will come with a rotor tip-to-housing clearance of between .004” and .007”; Once that clearance is above .0079″ it is no longer NFPA compliant). An airlock prevents air leakage across the pressure differential.

Airlocks Used in Bulk Material Handling

Drop-through airlock. What is beneficial about this airlock is that the cost is lower because it is more widely available. The downfall to the drop-through airlock is the head height.

Drop-through airlock with rails. Customers appreciate this airlock because it is operator and maintenance-friendly. The drawback to this airlock is the cost on the application’s front end.

Blow-through airlock. Compared to the drop-through airlock, the blow-through lock is preferred because of its head height and the feature that no pick-up shoe is needed. The blow-through airlock is avoided at times because of the cost and the few options it provides.

Airlocks and NFPA Compliance

Airlock systems are one of the most important components of an equipment’s success. Knowing the application will determine whether the airlocks need to be NFPA Compliant.

The National Fire Protection Association is an organization that is devoted to eliminating death, injury, property, and economic loss due to fire, electrical and related hazards. The NFPA Codes & Standards states that the airlock has a minimum of 8 vanes. At least two vanes must always stay in contact with each side of the housing, and the vanes must be at least 3mm thick. This helps keep flames contained to the rotor pocket if there is an explosion. Plastic or rubber tips are not NFPA compliant, as they will not hold up to the heat of an explosion. It’s also important to know that rotor-to-housing clearance must stay below .0079″ (0.2mm).

SELECTING AN AIRLOCK

Many factors go into selecting the right airlock for a project. Knowing the environment to which the airlock will be exposed is a vital consideration.

Temperature is a key factor, so it is important to know if the airlock will be indoor or outdoor, and the temperature of the material being conveyed.
Pressure above or below the throughput needs makes a difference.
Product details surrounding the airlock need to be considered to select the proper airlock; i.e. bulk density, angle of repose, flowability, abrasiveness and explosiveness are all product characteristics that can affect the airlock.

When questioning which airlock system is best suited for a project, consider the airlock itself; body type, body material, rotor style/material, inboard vs. outboard bearings, and gland vs. air purge shaft seal play into what airlock will perform the best.

There are many options to rotary airlocks.

The shallow pocket types reduce the volume per requirement and are generally used on filters, cyclones and silos.
A staggered pocket rotor has a continuous and uniform flow to provide a more accurate rate of material flow.
Fine Dosing rotors are beneficial when feeding or discharging fine powders, materials or granules that are contained in hoppers and silos.
A scalloped rotor is best suited for sticky materials or food-grade applications.
Flexible tip rotors are helpful when trying to avoid jams in the valve and are more suited for dust filters than food-grade applications.
Consider an adjustable rotor when handling more abrasive material.

Rotary airlocks can also offer a variety of features.

A low-cost feature with a high reward is a shaft seal air purge. A shaft seal air purge will prevent material from entering the seals and bearings.

A Zero Speed Switch is a valuable feature where it alerts the system if the rotor stops spinning, jams, or breaks.

Although they have a high price point, Slider Rails allows access for cleaning and maintenance.

The material and the coating of an airlock is critical. Nickel plating, chrome plating, and tungsten coating all help prevent premature wear of the airlock.

Factors, options, and features of the airlock system can be overwhelming. Working with a skilled team of knowledgeable engineers in the field can help. With over 25 years of experience, HaF Equipment is that team Ready To Connect!
