Description

Technical Field

[0001] The utility model relates to the field of edible and medicinal fungus culture medium preparation, in particular to a culture medium raw material injection mechanism. Background Art

[0002] Cordyceps flower is also known as northern cordyceps and Cordyceps militaris. Its ingredients are similar to those of Cordyceps sinensis. As a precious edible and medicinal fungus, Cordyceps flower is listed as one of the three major tonics in China along with ginseng and deer antlers. The current production process of Cordyceps flower includes the preparation of cultivated species → preparation of culture medium → sterilization and inoculation → shelf germination → grass management → harvesting → storage. In the prior art, the production process of Cordyceps flower culture medium is mainly based on the combination of manual labor and labor tools. This method has the problems of high labor intensity and low accuracy of the configuration ratio of culture medium raw materials. The materials required for the preparation of Cordyceps flower culture medium include solid grains and liquid culture solution. During preparation, it is necessary to load grains and culture solution in a fixed ratio according to the volume of the container, and then coat the container with a film to complete the sealing for the subsequent "sterilization and inoculation" process.

[0003] A Chinese utility model patent with authorization announcement number CN209205125U discloses a modified culture medium injection device, which includes a storage box, a stirring device, a pumping device, an injector and other equipment. However, the device is mainly aimed at plant tissue culture medium. In order to solve the problem of culture medium solvent stratification that is prone to occur during the storage process of the culture medium before filling, the device is not suitable for the preparation of culture medium for edible and medicinal fungi such as Cordyceps sinensis.

[0004] A Chinese utility model patent with authorization announcement number CN217962319U discloses a production line for a straw powder plate culture matrix, which includes a crushing tank and a stirring tank. The device first crushes the material with a crushing knife and then stirs and mixes it. The preparation of the culture medium for edible and medicinal fungi such as Cordyceps flowers is to directly mix solid materials such as grains with liquid materials such as culture fluid in proportion. It does not require further crushing of materials such as grains, but requires accurate control of the ratio of solid materials such as grains and liquid materials such as culture fluid.

[0005] A Chinese utility model patent with authorization announcement number CN206713483U discloses an inoculation device for transferring Cordyceps militaris liquid to solid culture medium, but the device mainly uses an inoculation gun to complete subsequent inoculation work and is not used for culture medium preparation.

[0033] The working principle of the utility model is:

[0034] When the utility model is working, solid materials (grains) are placed in the solid hopper 2. When the culture medium basin is transmitted to the injection station through the transmission line 6, the solid materials in the solid hopper 2 are injected into the culture medium basin through the solid discharging mechanism 1 to control the discharging flow rate. The material box 101 in the solid discharging mechanism 1 moves left and right to change the alignment number or alignment area of ​​the material box discharge port 107 thereon and the hopper discharge port 201, thereby changing the discharge flow rate of the solid material to achieve the purpose of adjusting the output amount of the solid material. When the material box discharge port 107 and the hopper discharge port 201 are completely offset, the remaining part of the material box 101 blocks the hopper discharge port 201, and the solid material cannot be output and fall, thereby realizing the solid material discharge closing function. The liquid material (culture solution, water, etc.) is injected into the culture medium basin through each liquid material pipe respectively, and each liquid material pipe is provided with a flow control valve for controlling the output flow of the liquid material. In this way, the utility model controls the solid material discharge flow rate adjustment and the liquid material output flow rate adjustment through the control system to achieve the purpose of accurately controlling the culture medium material ratio.
