Description

Sterilization method for edible fungus culture medium

Technical Field

The invention relates to the field of culture medium sterilization methods, in particular to a sterilization method for an edible fungus culture medium.

Background

The edible fungi refer to edible mushrooms with large fruiting bodies, are generally called mushrooms, have extremely high edible value and medicinal value, are delicious and rich in nutrition, are often called as health foods by people, for example, the mushrooms contain various amino acids necessary for human bodies, have the effects of reducing cholesterol in blood and treating hypertension, and are found to contain substances for enhancing the anticancer capability of the human bodies, so that the mushrooms, the flammulina velutipes and the hericium erinaceus are important economic crops.

The current edible fungi cultivation technology is relatively mature and can be roughly divided into several stages of breeding, culture medium preparation and hypha growth, wherein the culture medium of edible fungi mostly contains a large amount of organic matters, which usually contain a large amount of various microorganisms, and these microorganisms often adversely affect the growth of edible fungi and affect the cultivation of edible fungi, so that the culture medium needs to be sterilized in the process of culture medium preparation.

The common sterilization method in the preparation of the edible fungus mother culture medium is a high-pressure steam sterilization method, which is the most common and thorough sterilization method, and the high temperature of high-pressure steam is utilized to inactivate microorganisms such as bacteria in the culture medium so as to meet the requirement of edible fungus cultivation, but the high-pressure steam easily permeates into the culture medium in the sterilization process to cause overhigh water content in the culture medium and influence the normal growth of edible fungi, so that in the high-pressure steam sterilization process, the perfect sealing treatment needs to be carried out on a culture medium container, the bottling and taking-out efficiency of the culture medium is influenced, and the sterilization efficiency of the culture medium is influenced.

Disclosure of Invention

1. Technical problem to be solved

Aiming at the problems in the prior art, the invention aims to provide a method for sterilizing an edible fungus culture medium, which can realize that a wide-mouth container is selected to contain the culture medium in the process of sterilizing the culture medium, so that the bottling and taking out of the culture medium are facilitated, and the sterilization efficiency of the culture medium is increased.

2. Technical scheme

In order to solve the above problems, the present invention adopts the following technical solutions.

A sterilization method for an edible fungus culture medium mainly comprises the following steps:

s1, coarse grinding of the raw materials of the culture medium, and breaking of lumps in the raw materials of the culture medium;

s2, filling raw materials, namely filling the coarsely crushed culture medium raw materials into a culture medium container, and sealing the culture medium container;

and S3, sterilizing the culture medium container filled with the culture medium raw material by high-pressure steam, placing the culture medium container into a high-pressure steam sterilizing device for sterilizing, and inactivating the microorganisms in the culture medium raw material.

Furthermore, the culture medium container comprises a wide-mouth bottle, the wide-mouth bottle is filled with an edible fungus culture medium, an opening at the upper end of the wide-mouth bottle is inserted with a connecting sleeve matched with the wide-mouth bottle, the connecting sleeve comprises a fixing part, an inclined plane groove is formed in the upper end of the fixing part, a steam through hole is fixedly formed in the bottom of the inclined plane groove and penetrates through the fixing part, a sealing cover matched with the steam through hole is inserted in the steam through hole and comprises a cover body, a steam channel is formed in the cover body and is communicated with the wide-mouth bottle and the outside, a supporting net matched with the steam channel is fixedly connected to the opening at the upper end of the steam channel, a waterproof curtain is arranged at the upper end of the supporting net, the supporting net is fixedly connected with the central part of the waterproof curtain, a plurality of tearing grooves are formed in the waterproof curtain, the edge parts of the waterproof curtain are cut into a plurality of sectors by the tearing grooves, and a soil loosening device is fixedly connected to the lower end of the fixing part, the soil loosening device comprises a power source, the power source is fixed at the lower end of a fixing part, a power output end of the power source is fixedly connected with soil loosening units matched with the power source, two adjacent soil loosening units are connected end to end, each soil loosening unit comprises a connecting rod, a mounting groove matched with the power output end of the power source is formed in one end, close to the power output end of the power source, of each connecting rod, a positioning table matched with the mounting groove is formed in one end, far away from the mounting groove, of each connecting rod, a positioning ring matched with the corresponding positioning table is clamped and connected to the outer side of each positioning table, a positioning plate matched with the positioning table is formed in the inner wall of each positioning ring in a chiseled mode, a plurality of fan blades are fixedly connected to the outer wall of each positioning ring, and a fixing cover is fixedly connected to the positioning table of the soil loosening unit located at the lowest end, can realize in the culture medium sterilization process, choose wide mouthful container for holding the culture medium for use, the bottling and the taking out of the culture medium of being convenient for increase culture medium sterilization efficiency.

Furthermore, a sealing gasket is connected between the wide-mouth bottle and the connecting sleeve, and the sealing gasket is fixedly connected with the wide-mouth bottle, so that the sealing effect between the wide-mouth bottle and the connecting sleeve is improved, external high-pressure steam is difficult to enter the wide-mouth bottle through a gap between the wide-mouth bottle and the connecting sleeve, and the culture medium filled in the wide-mouth bottle is difficult to influence.

Furthermore, a sealing rubber block is arranged between the cover body and the connecting sleeve and fixedly connected with the cover body, the sealing rubber block can adapt to the inclined plane groove, and the sealing performance between the connecting sleeve and the sealing cover is not easily influenced after the sealing cover is mounted and dismounted for many times.
