Abstract: A fluidized bed conveyor belt freezer system including at least one wire mesh conveyor belt in a freezer housing with a plurality of coil arrays and centrifugal fan assemblies that produce a high volume of cold air directed directly upward to a plurality of adjustable vanes mounted under the belt. The vanes are longitudinally aligned and evenly distribute the volume of cold air through the conveyor belt to efficiently fluidize, freeze the product transported on the conveyor belt. The volume of cold air in the fan chamber is produced by a plurality of fan assemblies that draw cold air from the coils, uniformly mixed and delivered to the entire length of the bottom of the conveyor belt. The vanes are adjusted to distribute the cold air in the fan chamber through the conveyor belt to prevent blowouts. The fan motors are mounted externally on the freezer housing for easier servicing.

Abstract: A fluidized bed conveyor belt freezer system that includes at least one wire mesh conveyor belt in a freezer with a plurality of coil arrays and fans that produce a high volume of cold air directed upward into a plurality of air deflection vanes mounted under the belt. The vanes are equally spaced apart and longitudinally aligned under the conveyor belt to evenly distribute the cold air in the fan chamber through the belt to efficiently fluidize and freeze product transported on the belt with minimal waste. The volume of cold air in the fan chamber is produced by a plurality of fan assemblies that draw cold air from coils. The cold air in the fan chamber is uniformly mixed to a constant low temperature and moves at the same velocity. The vanes efficiently divide and distribute the cold air in the fan chamber through the belt, quickly freezing the product.
