PERFECTIONNEMENTS AUX INSTALLATIONS DE CONGELATION

摘要

A system for processing products such as food products, and more particularly comprising apparatus for loading food products into trays and for stacking the food carrying trays in vertically nested, individual stacks. The system includes apparatus for moving the stacks through a temperature controlled anteroom into a freezing chamber and a plurality of individually operable conveyor beds in the freezing chamber are provided for selectively receiving the stacks, storing the stacks for different selected processing times, and discharging the stacks. Apparatus is provided for receiving a stack of trays from any selected conveyor bed and removing it from the freezing chamber through a temperature controlled discharge anteroom. The system also includes apparatus for unstacking the stacks of discharged, frozen food carrying trays, and apparatus for unloading the product from the trays downstream of the unstacking apparatus. The unloaded trays are cleaned and returned to the loading apparatus to be reloaded with unfrozen food products.
