Energy-saving sterilization unit and use method

Abstract

The invention discloses an energy-saving sterilization unit and a use method. The energy-saving sterilization unit comprises a sterilizer, an inner heat exchanger is arranged in the sterilizer, and the sterilizer is connected with a high-pressure steam source; the sterilizer is connected with a sterile gas inlet pipeline, and the sterile gas inlet pipeline can introduce compressed gas into the sterilizer; and the energy-saving sterilization unit further comprises a hot water storage tank and a steam compressor. The problem that a water-containing material in the sterilizer bursts due to rapid cooling is solved, heat is recycled, heat energy consumption is reduced, and sterilization efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of high-temperature steam sterilization, and in particular relates to an energy-saving sterilization unit and a use method. Background technique [0002] The information disclosed in this background section is only intended to increase the understanding of the general background of the present invention, and is not necessarily taken as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to those skilled in the art. [0003] When edible fungus culture medium or packaged food, beverage and other materials are sterilized by high-pressure steam in the sterilizer, it generally goes through the process of loading - reciprocating preheating and vacuuming - heating - heat preservation - natural cooling - discharge. After sterilization, the material needs to be cooled to about 85°C before discharging. Due to high-pressure steam sterilization, the temperature and ai...

AI Technical Summary

Problems solved by technology

After sterilization, the material needs to be cooled to about 85°C before discharging. Due to high-pressure steam sterilization, the temperature and air pressure in the sterilizer are relatively high. If it is a solid material without water, generally use decompression The cooling method is used to reduce the temperature, but the inventor found that if it is a material with a high moisture content, in the process of decompression, the sterilized material will generate water vapor due to self-heating, and the packaging will burst.

Therefore, materials with high moisture content generally need to be cooled to below 100°C by natural cooling, but the process of natural cooling takes a long time, the working efficiency of the sterilizer is low, and all the heat lost naturally by this part is lost. wasted
