Abstract: The method of the invention is based on the comparison of local vapor concentrations at the inlet and outlet refrigeration ports and taking action based on that comparison. Control apparatus incorporating the invention is installed inside a refrigeration enclosure, adjacent to a port, preferably at the lowermost port. If the enclosure contains multiple ports at similar height, then each port has a form of the control apparatus attached to it. The control apparatus adjusts a flow of vapor leaving the interior of the enclosure. The control apparatus includes a duct assembly and a blower system. The bottom portion of the duct assembly is a tunnel enclosure through which a conveyor belt passes. Connected to an inside edge of the tunnel enclosure is a duct that extends upward from the conveyor belt. A blower for this duct either sucks vapor away from the conveyor belt or blows vapor from the enclosure interior toward the belt. Regardless of the flow direction, a vapor curtain forms inside the tunnel enclosure and represents a transitional region from all vapor to all air. Control of the blower for the duct assembly is based on vapor concentrations in the tunnel enclosures adjacent to each port. A microprocessor compares measured concentration levels and alters the blower motor frequency in such a manner as to minimize the difference in concentration levels at each port.

Abstract: A chiller or tunnel freezer for rapid chilling of chicken carcasses and the like wherein a cryogen such as liquid nitrogen or carbon dioxide snow is sprayed directly on the carcasses or other items as they travel through a passage or tunnel, and wherein vortical flow of air and/or vaporized cryogen is effected within the chiller to continuously sweep the bottom surface of the chiller and recirculate cryogen from the bottom surface, thereby avoiding accumulation of liquid nitrogen or CO.sub.2 snow on the bottom surface. The vortical flow is preferably provided by one or more fans disposed within the tunnel. A deflector may be provided on the tunnel interior to direct recirculated cryogen onto the items being chilled. A damper may be provided to regulate fan output and thereby enable optimization of operational efficiency.

Abstract: A cryogenic freezer apparatus for food products, including a thermally insulated enclosure and conveyor means for conveying products through the enclosure. A cryogen unit in the enclosure produces cryogen vapor near the enclosure entrance, and a blower unit is located in the enclosure adjacent the entrance thereof. The blower unit is selectively reconfigurable in response to a blower control signal to selectively direct cryogen vapor in varying directions, drawing cryogen vapor away from a first portion of the enclosure and blowing cryogen vapor toward a second portion of the enclosure. A photocell unit outside the enclosure, adjacent the entrance thereof, detects cryogen vapor exiting the enclosure entrance and generates at least one sensor output signal in response thereto, being indicative of the amount of cryogen vapor exiting. A control unit is coupled to the photocell unit and to the blower unit for generating a blower control signal in response to the sensor output signal so that, with increasing vapor detected outside the entrance of the enclosure, the blower unit draws cryogen vapor away from the enclosure entrance. Also, upon detecting a decreasing amount of cryogen vapor exiting from the entrance of the enclosure, the blower unit directs less cryogen vapor away from the enclosure entrance to assure that intrusion of the ambient environment through the enclosure entrance is prevented.

Abstract: A cabinet freezer efficiently utilizes a liquid cryogen refrigerant in conjunction with a spiral conveyor which conveys a product load through a temperature gradient within the freezer. The freezer has a lower inlet and an upper outlet for the conveyor and food load thereon. The escape of cryogen vapors created in the freezer from the liquid cryogen is controlled such that at least about 80% of the vapors exit through the upper outlet which is at the warmest zone established as a part of the temperature gradient in the freezer.
