How Does the Quick Freezing Process Work?

A quick freezing process must connect with the whole food production line. Typical food processing flow includes food cleaning, corte, food preparation, quick freezing, packaging and cold storage. As a result, frozen food products maintain better texture, appearance, flavor, and nutritional value.

IQF Tunnel Freezing Process

The process usually starts with raw material preparation. Por ejemplo, vegetables need washing, clasificación, corte, blanquear, cooling, and draining. French fries need washing, peladura, corte, rinsing, blanquear, air drying, frying, deoiling, and cooling.

Entonces, products enter the stainless steel mesh belt evenly. The tunnel uses high-speed circulating cold air in many standard IQF models. The product can enter at about +15℃ and leave at about -18℃. Usually, freezing time stays around 8–20 minutes.
