ABSTRACT:
A refrigeration apparatus comprises a chilling compartment within a housing enclosing the chilling compartment and a refrigeration system for directing cold air into the chilling compartment. Cold air enters the chilling compartment through a plurality of inlet nozzles located in the walls of the compartment housing. A chilled air manifold connects the inlet nozzles to the refrigeration system. A control circuit includes an air temperature controller for selectively setting the air temperature. A timer and on/off controls are incorporated in the control circuit. A moisture sensor monitors the moisture of the chilled air flowing into the chilling compartment and terminates air flow into the compartment when the moisture in the air exceeds a predetermined level. The moisture on the drier bed is removed during a regeneration cycle, which directs hot air flow through a drier for reducing the water content to an acceptable level on the drier bed contents.
