Method of continuous freezing of food products in bulk, especially of fruits and vegetables, and an apparatus for application of the method

摘要

Freezing in streams of cooled air is carried out at two stages, whereof the first one whose purpose consists in superficial preliminary freezing of the product proceeds in a fluidic bed, and the second one consisting in deep freezing proceeds on a grid conveyor. The fresh product fed to the fluidic bed is spread uniformly over its surface. The grate of the fluidic chute is provided with cleaning combs preventing the possibility of the particles of the product freezing to the chute.
