Safe pressure steam sterilization pot high in residual heat utilization rate

Abstract

The invention belongs to the technical field of food production equipment, and relates to a safe pressure steam sterilization pot high in residual heat utilization rate. The safe pressure steam sterilization pot comprises a sterilizing chamber and a steam generating chamber, wherein the sterilizing chamber and the steam generating chamber are separated by a partition board; steam enters the sterilizing chamber through through holes to perform sterilization on substances in the sterilizing chamber, so that the situation that the steam is in direct contact with the substances, and the substancesare damaged is avoided; a PLC control device is high in visual degree, and convenient to operate and observe, so that the safety performance is improved; a steam residual heat recovering device is arranged, so that after sterilization is completed, redundant steam can be pumped by a steam drawing device, after heat exchange is performed, the steam converts to liquid, then the liquid is returned to the steam generating chamber again, cyclic utilization is performed, cost is greatly saved, the recovered heat quantity can also be used for other foods which need heating or drying, the utilizationrate of residual heat is increased, and the effect of energy saving is achieved; the purpose of releasing pressure can also be achieved, and the situation that the redundant steam is directly exhausted by a pressure releasing valve, so that energy sources are wasted is avoided; and sliding rails are arranged, so that the sterilizing chamber is convenient to draw out, and articles are convenient to place and take out.

Description

technical field [0001] The invention belongs to the technical field of food production equipment, and relates to a safe pressure steam sterilizer with high waste heat utilization rate. Background technique [0002] Food refers to all kinds of finished products and raw materials for human consumption or drinking, as well as articles that are both food and medicine according to tradition, but does not include articles for the purpose of treatment. From the perspective of food hygiene legislation and management, the broad concept of food also involves To: the raw materials of the food produced, the planting of food raw materials, the substances and environment in contact with the breeding process, food additives, all packaging materials and facilities that directly or indirectly contact with food, and the environment that affects the original quality of food. [0003] Quick-frozen food is quick-frozen food processed at a rapid low temperature (below -18°C). The water and juice ...

AI Technical Summary

Problems solved by technology

[0005] High-pressure steam sterilizers are widely used in scientific research, food industry, bioengineering, medical and health and other fields. They are usually used to sterilize equipment, instruments or culture media. As the steam pressure rises, the temperature rises accordingly, and the heat penetration ability is enhanced. Sterilization can be carried out within a certain temperature range. At the same time, this sterilization method will not cause damage; the existing steam sterilizers are often complex in structure , the sterilization effect is not good, and the safety needs to be improved. At the same time, most of the steam heat after the sterilization is directly discharged through the exhaust valve, resulting in energy waste.
