Variable-temperature sterilizing tank

Abstract

The invention aims to provide a variable-temperature sterilizing tank with a simple structure, a reasonable design and adjustable internal space. The variable-temperature sterilizing tank comprises asterilizing tank body, a steam generator and a sealing door; the front end of the sterilizing tank body is open; the sealing door is hinged with the opening position of the front end of the sterilizing tank body; the variable-temperature sterilizing tank further comprises an outer barrel; the sterilizing tank body is coaxially installed in the outer barrel rotationally; an annular cavity is formedbetween the outer wall of the sterilizing tank body and the inner wall of the outer barrel; at least one vent hole making the annular cavity communicate with the inner cavity of the sterilizing tankbody is formed in the side wall of the sterilizing tank body; a steam outlet end of the steam generator communicates with the annular cavity through a steam guide tube; a push plate is glidingly installed in the sterilizing tank body in the axial direction; the peripheral side of the push plate is fixedly provided with a rubber ring used for sealing; the at least one vent hole is always located atthe front end of the push plate; the variable-temperature sterilizing tank further comprises a drive mechanism for independently driving the sterilizing tank body to rotate and the push plate to slide; two annular pressing plates are arranged in the annular cavity in an axial sliding manner; and the annular pressing plates are near the end part of the outer barrel.

Description

technical field [0001] The invention relates to a sterilization tank, in particular to a variable temperature sterilization tank. Background technique [0002] High pressure steam sterilization, high temperature plus high pressure sterilization, not only can kill general bacteria, fungi and other microorganisms, but also has a killing effect on spores and spores. It is the most reliable and most widely used physical sterilization method. High pressure steam sterilization It is widely used in the field of food processing. [0003] The traditional high-pressure steam sterilizer is mainly composed of a sterilizing tank, a controller, a steam generator, and various joints and control valves. The steam generator passes the generated high-temperature steam into the sterilizing tank to sterilize the food. During the process, the internal space of the retort can not be changed. Therefore, when the amount of food to be sterilized is small, a sufficient amount of steam still needs to...

[0003] The traditional high-pressure steam sterilizer is mainly composed of a sterilizing tank, a controller, a steam generator, and various joints and control valves. The steam generator passes the generated high-temperature steam into the sterilizing tank to sterilize the food. During the process, the internal space of the retort can not be changed. Therefore, when the amount of food to be sterilized is small, a sufficient amount of steam still needs to be introduced into the retort, resulting in energy waste
