A food low-temperature cooling machine is an essential piece of equipment designed to rapidly reduce the temperature of food products to prevent bacterial growth, preserve freshness, and comply with food safety regulations. This article explores the importance, working principles, applications, and benefits of low-temperature cooling machines in the food industry.
What is a Food Low-Temperature Cooling Machine?
A food low-temperature cooling machine is a specialized refrigeration system that quickly lowers the temperature of food products to safe levels, typically between 0°C and 4°C (32°F to 39°F) or even lower for freezing applications. These machines are widely used in meat processing, dairy production, bakery, seafood preservation, and ready-to-eat meal preparation.
Unlike conventional refrigeration, low-temperature cooling machines use advanced cooling technologies such as blast chilling, cryogenic cooling, or liquid nitrogen cooling to achieve rapid temperature reduction, minimizing the risk of microbial contamination and preserving food texture and nutrients.
How Does a Low-Temperature Cooling Machine Work?
The primary function of a food low-temperature cooling machine is to remove heat from food products efficiently. The cooling process involves the following key components and steps:
1. Evaporator Coils – These coils absorb heat from the food, causing the refrigerant inside to evaporate.
2. Compressor – The refrigerant gas is compressed, increasing its temperature and pressure.
3. Condenser – The hot refrigerant releases heat to the external environment and condenses back into a liquid.
4. Expansion Valve – The liquid refrigerant expands, reducing its pressure and temperature before re-entering the evaporator.
In blast chillers, powerful fans circulate cold air at high speeds to ensure uniform cooling. In cryogenic cooling systems, liquid nitrogen or carbon dioxide is sprayed directly onto food for ultra-fast freezing.

Unlike standard refrigeration, they deliver precise temperature control to slow microbial growth, reduce food waste, and maintain nutritional value—making them indispensable for processors, distributors, and retailers worldwide. This comprehensive guide addresses four core pillars for B2B users: step-by-step user operations, real-world user feedback, proactive maintenance requirements, and streamlined quick installation—all optimized for Google SEO to enhance visibility on 官网 (official websites) and B2B platforms like Alibaba or Thomasnet.
Proper operation ensures optimal performance, extends machine lifespan, and mitigates food safety risks. Below is a structured user guide, including pre-operation checks, core functions, and troubleshooting for common issues—tailored to B2B staff (e.g., warehouse operators, kitchen managers) with varying technical expertise.
Before powering on the machine, complete these 5 critical steps to avoid malfunctions:
Visual Inspection: Check for external damage (dents, loose wires) and ensure door seals are intact (no cracks or gaps—these cause cold air leakage and energy waste).
Temperature Verification: Use a NIST-certified thermometer to cross-check the machine’s digital display (target range: -5°C to 8°C). If there’s a discrepancy >±0.5°C, calibrate the sensor (see Section 1.3).
Load Preparation: Ensure food is properly packaged (airtight containers for liquids, breathable bags for fruits/vegetables) to prevent condensation or cross-contamination. Do not load hot food (>30°C) directly—cool it to room temperature first to avoid overworking the compressor.
Airflow Check: Clear air vents (inside and outside the machine) of debris or food residue. Blocked vents reduce cooling efficiency by 30–40%.
Power Supply Test: Confirm the machine is connected to a dedicated circuit (110V/220V, 50/60Hz) with no other high-power devices (e.g., ovens, freezers) sharing the same outlet.
Once pre-operation checks pass, follow these steps for safe use:
Power On: Press the main power button (typically red, located on the control panel) and wait 2–3 minutes for the system to initialize. The digital display will show the current internal temperature.
Set Target Temperature: Use the “+/-” buttons on the control panel to adjust the temperature based on the food type (see Table 1 for recommended settings). Press “Confirm” to save the setting— the machine will start cooling automatically.
Load Food: Place packaged food on shelves, leaving at least 5cm of space between items and the machine walls. This ensures uniform airflow—overloading or blocking vents causes temperature hotspots (risking food spoilage).
Monitor Operation: Check the digital display every 2 hours to confirm temperature stability. Most machines have a built-in alarm (audible and visual) that triggers if the temperature deviates by >±1°C—if this happens, refer to Section 1.4 (Troubleshooting).
Unload Food: When removing items, open the door quickly (limit to 30 seconds per opening) to minimize cold air loss. After unloading, wipe the interior with a food-grade sanitizer (avoid abrasive cleaners) to maintain hygiene.
Power Off (End of Day): Press the power button to shut down the machine. If not in use for >24 hours, empty all food, defrost (if manual defrost model), and leave the door slightly ajar to prevent mold growth.
Over time, sensors may drift—calibrate every 3 months to ensure accuracy:
Place a NIST-certified thermometer inside the machine, away from vents.
Set the machine to 2°C and let it run for 4 hours (stable temperature).
Compare the digital display to the thermometer:
If discrepancy ≤±0.3°C: No action needed.
If discrepancy >±0.3°C: Press “Calibrate” on the control panel (hold for 5 seconds), then use “+/-” to match the thermometer reading. Press “Save” to confirm.
