Abstract

431,844. Cooking and sterilizing canned, bottled, &c. goods. WEBSTER, R. W., and WEBSTER, A. H., 224, Nether Street, Finchley, London. March 1, 1935, No. 6519. [Class 49] In apparatus for cooking and sterilizing comestibles enclosed in cans, bottles, or other containers, in which the containers are taken by a conveyer M through a series of treatment chambers, the sterilizing chamber B, C, D containing steam or other vapour under pressure and having its entrance and exit closed by a water seal H, K the height of which is dependent on the pressure in the chamber, means are provided for automatically relieving the pressure when it exceeds the normal. As shown, the apparatus consists of a cooling tank A, through which the treated containers are passed mounted above which is the sterilizing chamber divided into compartments B, C, D and combined with open-ended compartments E, F forming the water seals which are connected by a pipe G. Within chamber B, and if desired also within chamber D, a pressure relieving pipe a is provided the lower end of which is below the water level H but above the point b at which the seal might be broken and the upper end is outside the chamber B and is protected by a cowl c enclosed by a splash tank d communicating through pipe e with compartment E. On excess steam pressure developing in the sterilizing chamber the water level H will be lowered and steam will escape up pipe a. Water forced up by the steam will be discharged into tank d and returned through pipe e to compartment E. The pressure-relieving device may be used with the sterilizing-apparatus set forth in Specification 377,890.
