Edible mushroom culture medium sterilization method

Abstract

The invention discloses an edible mushroom culture medium sterilization method, and belongs to the field of culture medium sterilization methods.According to the scheme, firstly, culture medium raw materials are subjected to coarse grinding and then added into a wide-mouth bottle, filling of the culture medium raw materials can be greatly simplified due to digging of an inclined-plane groove, and therefore the culture medium raw materials can be completely sterilized; after filling is completed, the connecting sleeve is sealed through the sealing cover, raw material filling is completed, then the culture medium container filled with the culture medium raw materials is put into the high-pressure steam sterilization device for sterilization work, external steam can be prevented from entering the wide-mouth bottle through the waterproof curtain, the culture medium raw materials are loosened through the soil loosening device, and the wide-mouth bottle is filled with the culture medium raw materials. On one hand, heat conduction is facilitated, the sterilization effect is improved, on the other hand, follow-up cultivation of edible mushrooms is also facilitated, in the culture medium sterilization process, a wide-opening container is selected for containing a culture medium, the culture medium can be conveniently bottled and taken out, and the culture medium sterilization efficiency is improved.

Description

technical field [0001] The invention relates to the field of culture medium sterilization methods, and more particularly, to a method for sterilizing culture medium of edible fungi. Background technique [0002] Edible mushrooms refer to mushrooms (large fungi) with large fruiting bodies that can be eaten, commonly known as mushrooms, with extremely high edible and medicinal value. Edible mushrooms are not only delicious, but also nutritious. , such as shiitake mushrooms not only contain various essential amino acids, but also have the effect of lowering blood cholesterol and treating high blood pressure. It is also found that shiitake mushrooms, mushrooms, enoki mushrooms, and Hericium erinaceus contain substances that enhance the body's anti-cancer ability, which is an important economic crops. [0003] Today's edible mushroom cultivation technology is relatively mature, and can be roughly divided into several stages: breeding, medium preparation and mycelial growth. The ...

AI Technical Summary

Problems solved by technology

[0004] The commonly used sterilization method in the production of edible fungus parent culture medium is high-pressure steam sterilization, which is the most commonly used and most thorough method of sterilization. It uses the high temperature of high-pressure steam to sterilize bacteria and other microorganisms in the medium. Live treatment to meet the needs of edible fungus cultivation, but during the sterilization process, high-pressure steam is easy to penetrate into the medium, resulting in excessive moisture in the medium, affecting the normal growth of edible fungi, so high-pressure steam sterilization During the process, the medium container needs to be fully sealed, which affects the efficiency of bottling and taking out the medium, and affects the sterilization efficiency of the medium
