Abstract
1,234,368. Refrigerators. INTEGRAL PROCESS SYSTEMS Inc. 13 March, 1970 [17 March, 1969], No. 12216/70. Heading F4H. In apparatus for freezing articles 24 which are conveyed through a heat-insulated chamber, at least a portion of the cryogenic liquid, e.g. nitrogen which is sprayed thereover from nozzles 39 is flashed to generate refrigerant gas which is recirculated by a fan 53 to the chamber to establish a flow of mixed fresh and returned gas in a portion of the chamber upstream of the spray section. The fan inlet 54 draws the gas from both the recirculating stream in the chamber above a baffle 50 below the conveyer and the freshly generated stream below the baffle and passes it through a plenum 52 whence it passes into the chamber either by deflection by a baffle 51 or through a passage 58 in the wall separating the plenum from the chamber. The gas flow through passage 58 is controlled by an adjustable baffle 59 actuated by a motor 62 controlled by a temperature responsive device 64 at the exit end of the chamber. An L-shaped gate controls the relative amounts of fresh and recirculated gas passing to the fan inlet 54 and means is described for feeding and regulating flow of liquid refrigerant to the nozzles.
