Extended information

Commonly used cooling methods include contact ice cooling, air cooling, water cooling, vacuum cooling, etc.

1. Contact ice cooling uses ice to directly contact the product to remove heat from the product. In addition to high cooling speed, melting ice can always keep the surface of the product moist. This method is often used to cool fish, leafy vegetables and some fruits, and is also used in the processing of some foods such as lunch meat.

2. The air cooling method uses cooled air as a cooling medium to flow through the food to absorb heat. Generally, the air temperature used when pre-cooling food should not be lower than the freezing temperature to prevent the food from freezing.
