Abstract

522,836. Freezing food &c. STONE, A. J. Dec. 19, 1938, No. 36908. Convention date, Dec. 17, 1937. [Class 29] In apparatus as described in Specification 488,791 for quick freezing of foods &c. alternate refrigerant chambers 19, which are wedge shaped, . are movable radially to widen the storage spaces 22 between them as the spaces successively reach the charging opening 23, the. movable chambers being guided by pin and slot devices 20, 21, Fig 5, and having pins 28a adapted to ride on the fixed inner drum 9 so as to be engaged by cams 28 on this drum opposite the charging opening. The chambers are afterwards pushed inwards by cams 29, Fig. 3, on the casing wall or are restored by springs 30, Fig. 1, or by both means. The refrigerant path through the chambers may be reversed by means of a valve 41 in the supply and discharge conduits, preferably actuated automatically and periodically with the drum rotation. Carbon dioxide gas may be supplied under pressure to the interior of the heat-insulated casing, to minimize freezing - on of the articles. The charging and discharging openings are provided with double doors, as at 34, 35, Fig. 1, to provide air locks.
