Sanitation Methods for Food Processing Equipment

by: Maria Buss and Nicole Johnson

With over three decades of expertise in bulk material handling, we understand the critical importance of sanitation in food processing operations. Ensuring both hygienic construction and effective cleaning methods is paramount in minimizing the risk of bacterial growth and foodborne illnesses caused by pathogens such as Salmonella and E. coli. The World Health Organization estimates that nearly 1 in 10 people globally fall sick each year from contaminated food, underscoring the need for rigorous sanitary practices. At HaF Equipment, we prioritize these principles, integrating Clean-in-Place (CIP) and Clean-out-of-Place (COP) systems into our machinery to provide comprehensive, efficient, and safe cleaning solutions that support the highest standards of hygiene in the industry. By leveraging these advanced systems in cleaning food processing equipment, we help our clients maintain optimal cleanliness, enhance operational efficiency, and ensure the safety and quality of their products.

Clean-in-Place (CIP) vs. Clean-out-of-Place (COP) Systems

At HaF Equipment, we prioritize systems that support CIP and COP cleaning techniques.

Clean-in-Place (CIP): These automated systems clean the internal surfaces of process equipment without disassembly. Clean-in-Place (CIP) systems offer an efficient solution for enhancing the sanitation process. By minimizing exposure to high temperatures and chemicals, they contribute to a safer workplace environment while also aiding in the effective management of water and chemical expenses. CIP is ideal for tanks, pipes, and pumps. When designing CIP systems, it is important to factor in additional components like extra ports, different gaskets, waterproof equipment, airlock dummy shafts, sprayballs, and wands to ensure thorough cleaning.

The benefits of CIP include:

- Reduced Labor Costs: Automating cleaning saves time and manpower compared to manual cleaning.
- Improved Safety: Eliminates the need for workers to handle harsh chemicals at high temperatures.
- Enhanced Cleaning Consistency: Automated systems deliver consistent cleaning results every cycle.

Clean-out-of-Place (COP): Equipment unsuitable for CIP cleaning, such as fittings, utensils, and tank vents, is cleaned in a COP system. These components are submerged in a tank containing a hot chemical solution and agitated for a deep clean. In the COP procedure, the immersion washer is crucial in effectively cleansing items. These elongated tanks utilize powerful jets of detergent solution to create agitation and remove residues from processed materials and ingredients while they are immersed in hot water. Subsequently, the components undergo a thorough sanitization process to ensure a deep clean. Once cleaned, the parts are reassembled and reintegrated into the manufacturing equipment. It is important to note, however, that prior to immersing equipment in a COP tank, heavily solid equipment must be pre-rinsed. Failure to do so may result in the chemical bath becoming overloaded with excess debris, leading to re-deposition on the cleaned equipment. Larger items that cannot be fully submerged in the tank may obstruct circulation ports, impeding turbulence and hindering the cleaning process. In such cases, manual cleaning is recommended. Smaller and more intricate equipment parts are better suited for COP systems as they are typically inaccessible through CIP procedures.

Key points about COP systems are:

- Effective for Complex Parts: Cleans intricate equipment parts that CIP systems may not reach.
- Manual Pre-Cleaning Necessary: Heavily soiled items require pre-rinsing before COP cleaning to prevent overloading the chemical bath.
- Visual Inspection Crucial: After cleaning, parts should be visually inspected or swabbed to verify cleanliness.

Choosing the Right Sanitary Design System

CIP and COP systems offer advantages, and the optimal choice depends on your specific needs. CIP systems generally require a higher initial investment but offer significant labor savings in the long run. The following table summarizes key differences:

Feature	CIP System	COP System
Cleaning Method	Automated	Immersion
Disassembly Required	No	Yes
Labor Intensity	Lower	Higher
Initial Investment	Higher	Lower

Comparing CIP and COP Systems

Equipment

Both CIP and COP systems require a range of equipment. These can include:

Pumps
Heat Exchangers
Sensors (temperature, etc.)
Tanks
Flow Meter
Strainer

Exceeds regulatory standards with the capability of cleaning deep crevices that are often overlooked during manual cleaning.

Tip: Using both systems will drastically improve overall cleanliness, potentially allowing a facility to forgo manual cleaning altogether.

Both systems utilize similar cleaning chemicals, typically including:

Caustic solution (breaks down bonds between contaminants and surfaces)
Acidic solution (neutralizes the caustic solution and removes mineral deposits)
Sanitizer/disinfectant (eliminates microorganisms)

The specific cleaning cycle steps will vary based on the equipment and product type.

A typical CIP cycle involves:

Pre-rinse
Wash
Intermediate rinse
Acid rinse
Sanitize
Final rinse

A typical COP cycle involves:

Dry cleaning
Rinse parts in the COP tank (with cool water under 80 degrees Fahrenheit)
Clean the equipment with a soap or chemical
Rinse the parts in the COP tank
Complete a visual inspection or swabbing (ensures the parts were adequately cleaned)
Sanitize the parts in the tank

Food manufacturers must invest in sanitary equipment design and implement effective cleaning procedures. By choosing systems that prioritize these elements, they can ensure a safe and hygienic production environment, safeguard their brand reputation, and promote consumer trust in their products.

For Fun: The History of Marshmallow Q: When were marshmallows first enjoyed? A: 2000 BC, Ancient Egypt. They were rare and a special treat reserved for gods and royalty. Q: How was it originally made? A: It was made from the root sap of the mallow plant, which grew in marshy areas, and mixed with nuts and honey. Q: What else can you use the mallow plant for? A: Heal sore throat, anti-inflammatory. The leaves can be used as a laxative. The plant contains mucilage, which the plants use to store water. That helps with these medicinal effects. Today, you can find the mallow root in teas, tinctures, capsules, ointments, creams, sodas, and cough syrups. Q: When was the modern marshmallow created? A: 19th century France. By this point (1927), the mallow root had been replaced by gelatin and/or egg whites. By 1950, Alex Doumak created the mass production extrusion process. Top two producers today: Kraft Heinz Company, Doumak, Inc.

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.
