Cryogenic tunnel freezer, IQF Individual quick freezer

The IQF freezer consists of an insulated cabinet with fans and a liquid nitrogen injection system. The liquid nitrogen at -196 C is injected into the freezer, where the fans instantly turn the liquid nitrogen to gaseous nitrogen. The super-cooled gas passes evenly over the food, quickly refrigerating the products. Typically, the IQF batch unit takes 20 minutes to refrigerate 100 kg of product.
