SS Evaporator for IQF

Evaporator for IQF

An evaporator for IQF (Individual Quick Freezing) is a key component in the IQF process, which is widely used in the food industry to quickly freeze individual food items. Here is an overview of the evaporator for IQF:

Function

The main function of the evaporator in an IQF system is to remove heat from the food products being frozen. It does this by facilitating the evaporation of a refrigerant. As the refrigerant evaporates, it absorbs heat from the surrounding environment, including the food items, causing them to freeze rapidly. This rapid freezing helps to preserve the quality, texture, and nutritional value of the food by minimizing the formation of large ice crystals, which can damage cell walls and affect the taste and texture of the food.

Working Principle

The evaporator operates based on the principles of heat transfer and phase change of the refrigerant. In an IQF evaporator, a low - pressure, low - temperature refrigerant is passed through a series of tubes or coils. The food products are placed in close proximity to these tubes or coils. As the refrigerant flows through the evaporator, it absorbs heat from the food and the surrounding air, causing the refrigerant to evaporate from a liquid state to a vapor state. The heat absorbed by the refrigerant is then carried away to the other components of the refrigeration system for disposal.
