Hygiene standards for refrigeration equipment in food processing workshops, key points for selecting clean-type units

Food production workshops have clear hygiene control requirements. Ordinary industrial refrigeration units have structures prone to accumulate oil and dirt, and crevices where contaminants can accumulate. Long-term use leads to the growth of bacteria, which does not comply with food production standards. Many small food processing factories purchase general cold storage units, but due to unqualified cleanliness levels, they face inspection and rectification. This article outlines the core standards for selecting food-specific clean refrigeration equipment for scenarios.
I. Design requirements for clean-type unit structure in food scenarios
First, the shells of the air coolers and condensers adopt non-angled arc structures to reduce oil accumulation and crevices, facilitating clean water rinsing and wiping; second, the surface of the fins is smooth with a coating that makes oil less likely to adhere, and daily cleaning only requires low-pressure water blowing; third, the pipe welds are flat without uneven crevices to avoid food residues, water vapor accumulation, and microbial growth; fourth, the electrical control boxes have a fully sealed waterproof design to prevent water vapor from seeping into the circuit and causing faults.
Ordinary units have many joint gaps and sharp edges, making it difficult to thoroughly clean after oil accumulation, and they cannot meet the regular hygiene control requirements of food workshops.
II. Anti-corrosion and rust prevention suitable for food high-humidity oil-contaminated environments
Food processing workshops have constant water vapor and volatile animal and plant oils, and the metal components of the equipment are prone to rust and flaking. Rust debris falling will contaminate the processed raw materials. Clean-type units with thickened anti-corrosion coatings and heat exchange copper tubes made of materials resistant to oil-contaminated corrosion can prevent rust in long-term high-humidity oil-contaminated environments, ensuring the clean standards of the workshop.
III. Differentiated clean configuration for different food categories
Fruit and vegetable pre-processing workshop: Basic clean coating, arc-shaped shell air cooler is sufficient; meat products, aquatic product processing workshop: Upgrade with thickened anti-corrosion coating, increase the spacing of the fins of the air cooler to reduce blood and fish scales attachment; Pre-cooked food high-temperature steaming workshop: Add a higher waterproof level to the electrical control box, and upgrade the entire machine to withstand high-temperature and moisture.
IV. Customized clean unit service for source factories in the food industry
Suzhou Xueying Refrigeration has optimized clean-type air-cooled units, air coolers, and condensers for the food processing industry. The entire machine adopts an easy-to-clean, non-angled arc structure. It can adjust the anti-corrosion coating grade according to the degree of oil and water vapor in the workshop and supports domestic food factories and overseas aquatic and meat processing bases to batch customize. The factory comes with equipment cleaning and maintenance specifications to guide the workshop to regularly rinse and maintain the equipment, maintaining the clean state of the equipment for a long time.
V. Standardized daily cleaning process for food equipment
After work each day, blow off the oil stains on the fins of the air cooler with low-pressure water; wipe the exterior of the unit and the surface of the pipes weekly; conduct a deep inspection of the pipe welds monthly, remove accumulated stubborn oil stains; increase cleaning frequency during rainy seasons to prevent mold from adhering. Summary
The core evaluation criteria for food processing refrigeration equipment are easy-to-clean structures without dead corners and oil-resistant and anti-corrosion protection. We select clean-type units specifically adapted for food production scenarios, combined with regular cleaning procedures. This not only meets the hygiene control requirements of the workshop but also extends the equipment's service life and avoids the costs of rectification and rework.
