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)

Material Processing in Soda - Manufacturing Equipment

Steps in Soft Drink Production

  1. 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.
  2. 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!
  3. 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.

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.

Material Handling Challenges When Handling Salt

handling salt in manufacturing

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.
