I. Fluid Control Product Solutions for the Food and Beverage Processing Industry
1. Typical Operating Challenges in the Food and Beverage Processing Industry
Equipment and materials in food and beverage manufacturing face numerous severe tests, primarily including:
Stringent Hygiene and Cleanliness Requirements: Direct product contact parts for process fluids (water, beverages, dairy products, sauces, etc.) require extremely low risk of microbial retention, particle shedding, and support Clean-In-Place (CIP) and Sterilize-In-Place (SIP). Equipment surfaces need very high smoothness (typically requiring Ra ≤ 0.8 μm or lower) to ensure no sanitary dead legs and prevent bacterial growth.
Corrosion and Wear: Processing involves acidic beverages (e.g., fruit juices, carbonated drinks), alkaline cleaning agents, chlorinated disinfectants (e.g., sodium hypochlorite), and high-salinity media (e.g., soy sauce, brine), requiring materials with good chemical corrosion resistance and wear resistance. For example, the pH of soy sauce typically ranges from 4 to 6.
Viscous and Particulate-Laden Materials: Handling viscous materials or those containing solid particles, such as jam, honey, ketchup, and pulp-containing beverages, requires equipment with low flow resistance, clog prevention, easy cleaning characteristics, and minimal shear damage to the product to maintain texture.
Temperature Fluctuations and Thermal Shock: Processes like pasteurization, UHT sterilization, and hot filling require equipment to withstand high temperatures (often >100°C), while cooling steps may involve low temperatures, demanding materials with good thermal stability.
High Reliability Requirements: Food and beverage production lines typically run continuously. Unplanned downtime leads to significant production losses, requiring fluid components to have extremely high reliability, long service life, and easy maintenance.

3. Brief Success Case Studies
Case 1: Pipeline System Retrofit for Soy Sauce Fermentation Tanks at a Well-Known Condiment Factory
Challenge: Soy sauce fermentation broth has a pH of 4-6, is acidic and corrosive. The original carbon steel valves suffered severe corrosion and poor hygiene conditions.
Solution: Key valves on the fermentation tank inlet/outlet pipelines were replaced with mirror-polished 316L stainless steel ball valves (Ra≤0.8μm). The CIP cleaning lines used PFA-lined valves and fittings.
Effectiveness: System corrosion resistance significantly improved. Third-party testing showed no signs of pitting after 5 years of continuous operation. Hygiene conditions greatly improved, bacterial control levels increased, and product quality became more stable.
Case 2: Pasteurization Production Line for a Dairy Company
Challenge: The pasteurization system required extremely high temperature control accuracy (±1%). The original valves had poor regulating performance, leading to large temperature fluctuations affecting product shelf life.
Solution: Implemented high-precision 316L stainless steel micro control valves and sanitary diaphragm valves in the heat exchange medium and product pipelines.
Effectiveness: Sterilizer temperature control accuracy significantly improved, pressure overshoot reduced from 8% to 1.5%. Product shelf life was extended, yielding considerable economic benefits.
II. Specific Application of Industrial Protection Products in the Food and Beverage Processing Industry
1. Typical Operating Challenges in the Industry
The exteriors of equipment and facilities in food and beverage processing plants also face many challenges, directly impacting production efficiency, cost, and safety:
Humid and Corrosive Environment: Production workshops are humid. Hot water, acidic/alkaline cleaning agents, and disinfectants are frequently used during cleaning, which can splash or form mist, corroding equipment housings, steel structures, pipelines, and valve exteriors.
Heat Loss and Energy Consumption: Heat dissipation from equipment surfaces like pasteurizers, UHT systems, steam pipes, hot water lines, and fermentation tanks leads to significant thermal energy loss, increasing operating costs. Simultaneously, high-temperature surfaces pose burn risks to personnel.
Dust and Explosion Risk: Handling powdered raw materials like flour, starch, milk powder, sugar, and spices generates combustible dust, posing a dust explosion risk, requiring effective dust removal and protective measures.
Equipment Wear and Mechanical Damage: Agitators and conveying equipment experience wear during operation; daily cleaning and maintenance operations can also damage external protective layers.
Difficult and Costly Maintenance: Repairing or replacing corroded or faulty equipment can impact production schedules. Therefore, protective products are required to have high durability and reliability to reduce unplanned downtime.
