Condensers and evaporators are widely used in the food industry for food processing, refrigeration preservation, and production process cooling. Their core functions and typical applications are as follows:
1、 Comparison of core functions
Condenser
Function: Condense gaseous refrigerant into liquid state and release heat to maintain efficient operation of the refrigeration system. For example, parallel unit heat dissipation can be achieved in cold storage through evaporative condensers (such as the Sik Refrigeration MKN-1700 model).
Technical features:
Evaporative condenser can save 60% water and is suitable for water scarce areas.
Air cooled condensers (such as Emerson scroll compressor units) are suitable for small cold storage and have high cost-effectiveness.
Evaporator
Function: By absorbing heat through refrigerant evaporation, it reduces the temperature of food or processing environments. For example, in the central kitchen, a cold air fan (side outlet type) is used to quickly cool down and adapt to frequent loading and unloading scenarios.
Technical features:
Forced convection design (such as axial flow fans) controls temperature fluctuations within ± 1 ℃.
Can be matched with different refrigeration units to meet the storage temperature requirements of -30 ℃ to 10 ℃.
2、 Typical application scenarios
Food Processing and Central Kitchen
Pre made dish cooling: Modular machines (such as the McQuay MAC series) provide -10 ℃ frozen water for rapid cooling and preservation of pre made dishes.
Production process cooling:
The chocolate production line requires -15 ℃ chilled water to cool the mixer jacket.
Salad dressing production uses a plate heat exchanger to lower the cooling tank water temperature to 5 ℃.
Cold chain logistics and warehousing
Cold storage system: The combination of evaporative condenser and air cooler achieves stable operation in the -18 ℃ freezer room.
Ice Flake Machine Refrigeration: By utilizing the principle of heat absorption through an evaporator, ice flakes are provided for food refrigeration (such as the Ferguson Sea Water Ship Ice Flake Machine).
3、 Technology Trends
Energy saving design: Evaporative cooling units (such as the McQuay MAC series) can still operate efficiently in low temperature environments of -20 ℃, saving more than 30% energy.
Accurate temperature control: Variable frequency technology (such as MAC A+series) achieves ± 0.5 ℃ water temperature control to ensure food quality.
The two work together to provide a full chain temperature control solution from processing to storage and transportation for the food industry, ensuring food safety and quality.
