Description

Technical Field

[0001] The utility model relates to the field of capping devices, in particular to a breathable capping for edible mushroom cultivation bottles. Background Art

[0002] Edible mushrooms are a common food ingredient, rich in essential amino acids, minerals, vitamins, polysaccharides and other nutrients for the human body. At present, the large-scale production of edible mushrooms has been realized. One existing method for cultivating edible mushrooms is plastic bag cultivation. The plastic bag cultivation method has the advantages of low cost and easy control of mushroom production quantity and shape according to cultivation requirements. Moreover, the structure of the plastic bag cultivation that closely adheres to the surface of the cultivation material and has a constricted opening can effectively reduce the generation of aging mycelium blocks, reduce the mycelium scratching process, avoid the formation of voids, and better reduce the generation of aerial mycelium. However, the problem with the plastic bag cultivation method is that the plastic bag has no fixed shape, which is not conducive to automated, standardized, and large-scale production.

[0003] In view of the defects of plastic bag cultivation, the cultivation bottle cultivation method has been developed. The cultivation bottle cultivation method has the advantage of being conducive to automated, standardized, and large-scale production. The existing cultivation bottle cultivation method generally includes steps such as the preparation of the cultivation material, bottling, sterilization, cooling, inoculation, cultivation, mycelium scratching, mushroom production, and harvesting.

[0004] However, the existing caps for cultivating edible mushrooms have the following problems:

[0005] Poor air exchange: In the existing cap designs, the air flow path is complex, which is not conducive to air exchange. For example, in the cap for edible mushroom bottle cultivation disclosed in CN210054097U, an air permeable hole is provided between the concave convex platform and the connecting block, and an air vent hole and a labyrinth convex rib are provided on the cap. The air exchange requires passing through the air permeable hole, the labyrinth convex rib, and the air vent hole. This side ventilation method has an air flow path that is not conducive to air exchange, and the labyrinth convex rib also hinders air flow.

[0006] Generation of aerial mycelium: In the existing cap designs, due to poor air exchange, aerial mycelium is likely to be generated in the cultivation material, increasing the mycelium scratching process, resulting in loss of the cultivation material, and may also contaminate the cultivation material. For example, in the cap designs disclosed in CN207733367U and CN208446243U, the external air exchange port is provided in the edge area of the lower cover. This side ventilation method has an air flow path that is not conducive to air exchange, leading to the generation of aerial mycelium. Content of the Utility Model
