[0045] The utility model also provides a kind of mushroom cultivation bottle, comprising:

[0046] The mushroom cultivation bottle cap as described above, and

[0047] Bottle body, the bottle body is top opening container shape, and is detachably and airtightly connected with the mushroom cultivation bottle cap;Wherein, the bottle body has inwardly retracted structure in the middle part in vertical direction.

[0048] In an optimal embodiment of the mushroom cultivation bottle, the bottle body is a hollow cylinder or a cube, preferably a hollow cylinder. Correspondingly, the top opening is circular or square, preferably circular. The shape and size of the top opening are consistent with the shape and size of the horizontal cross section inside the bottle body;In other words, the shape and size of the horizontal cross section inside the bottle body continue to the opening, becoming the shape and size of the top opening.

[0049] In one preferred embodiment of the mushroom cultivation bottle, the inwardly-contracted structure of the bottle body accounts for 1 / 10 to 9 / 10 of the height of the bottle body. Such an outer shape is particularly suitable for industrialized production using a large number of cultivation bottles. When a large number of cultivation bottles are used simultaneously, the cultivation bottles are densely arranged with each other, and the inwardly-contracted structure of the cultivation bottles forms gaps between them, facilitating the circulation of gas, especially the cooling of the cultivation stage, to avoid excessive temperature and reduce the activity of the spawn. Preferably, at least 1 / 10, preferably 1 / 10 to 3 / 10, of the lower part of the bottle body in the vertical direction does not have the inwardly-contracted structure, so as to maximize the volume of the bottom and increase the loading capacity of the culture medium. Preferably, the contraction amount of the inwardly-contracted structure is 1 / 100 to 1 / 30 of 1 / 2 of the width of the bottle body in the horizontal cross-section. The contraction amount of the inwardly-contracted structure in the vertical direction can be the same, but is preferably different, so as to form a concave-convex outer shape, increase the external surface, and further promote heat exchange between the inside and outside of the bottle body.

[0050] In one preferred embodiment of the mushroom cultivation bottle, the top outer edge of the bottle body has a protruding rib or other structure, such as an external thread, for detachable and airtight connection with the mushroom cultivation bottle cap.

[0051] In one preferred embodiment of the mushroom cultivation bottle, an inwardly-inclined structure, preferably a chamfered structure, is provided at the junction of the bottom surface and the side surface of the bottle body. The inwardly-inclined structure is beneficial for promoting the spread of mycelium throughout the mushroom cultivation bottle.

[0052] During sterilization of the culture medium loaded into the mushroom cultivation bottle (achieved by heating), it is desirable to quickly exhaust the gas in the bottle; during the first-stage cultivation of the sterilized culture medium after inoculation of the spawn, the required amount of gas exchange in the bottle is not large, and it is also undesirable to introduce pollution due to excessive amount of external gas; when the cultivation process reaches the second-stage cultivation, it is desirable to maximize the amount of gas exchange in the bottle. The mushroom cultivation bottle cap and the mushroom cultivation bottle of the present application have a circular arc top and an opening adjusting mechanism. The circular arc top creates a stable gas environment and facilitates the discharge of gas (along the arc surface). The opening adjusting mechanism can correspondingly adjust the opening area according to the step (such as sterilization, first-stage cultivation, and second-stage cultivation).

[0053] In actual use, the mushroom cultivation bottle cap of the present application can be used in combination with a known or prepared bottle body as needed, as long as the two can be combined into one. Therefore, the mushroom cultivation bottle cap can be used as an independent product in combination with a corresponding bottle body for mushroom cultivation.

[0054] To fully utilize the fungus cultivation bottle of the present application, especially during the fungus cultivation process, to better control the gas exchange amount between the inside and outside of the bottle body during the sterilization of the culture medium loaded in the cultivation container, primary fungus cultivation, and secondary fungus cultivation steps, and to fully exert the efficacy of the fungus cultivation bottle of the present application, the present application also provides a fungus production line comprising:

[0055] The fungus cultivation bottle as described above, and

[0056] An opening operation device for operating the opening adjusting mechanism of the fungus cultivation bottle to control the opening area.

[0057] In a preferred embodiment of the fungus production line of the present application, the opening operation device is movable in the vertical direction, so that the operating end, such as a rotating head, of the opening operation device can be combined with the upper cover of the fungus cultivation bottle.

[0058] In a preferred embodiment of the fungus production line of the present application, it further comprises a conveying system, such as a conveyor belt, which can move the fungus cultivation bottle into and out of the operating position of the opening operation device.

[0059] In a preferred embodiment of the fungus production line of the present application, it further comprises a cultivation bottle magazine, a plurality of fungus cultivation bottles, such as 4, 8, 12 fungus cultivation bottles, are arranged in the cultivation bottle magazine in a group, and the opening operation device can operate all the fungus cultivation bottles in the cultivation bottle magazine at one time.

[0060] During the fungus cultivation process, by timely controlling the opening area of the opening, it can ensure that the fungus cultivation is realized under the best aeration condition. For example, during the sterilization of the culture medium loaded in the fungus cultivation bottle, with the start of heating, the opening operation device adjusts the opening area to the maximum to promote the rapid discharge of the gas in the bottle; after the sterilization is completed, during the cooling process, the opening area is adjusted to be small to ensure that the amount of external gas entering the bottle is small, to reduce the probability of introducing pollution, until the primary fungus cultivation is completed, because the oxygen demand during the primary fungus cultivation process is low; when starting the secondary fungus cultivation step, the anti-pollution ability of the fungus body in the bottle has been improved, at the same time, the oxygen demand during the fungus growth process is also large, at this time, the opening area is adjusted to the maximum again to fully exert the potential of the equipment.

[0061] In various devices of the present application, such components can be made of ceramic, metal, quartz, glass, heat-resistant plastic, etc., and transparent material is preferably used; they are made by common molding and processing techniques, for example, by common glass processing and plastic molding techniques. Considering the cost, especially the need for repeated use, plastic material is preferably used.

[0062] The utility model also describes the use of the fungus cultivation bottle in fungus culture, comprising:

[0063] Preparation fungus cultivation bottle as described above;

[0064] Filling culture medium in the bottle body of the fungus cultivation bottle, and then covering the bottle body with the fungus cultivation bottle cover;

[0065] Adjusting the opening area of the fungus cultivation bottle cover to the maximum, and sterilizing (preferably by heating) the filled culture medium;

[0066] Removing the fungus cultivation bottle cover, and inoculating the sterilized culture medium with spores;

[0067] Covering the bottle body with the fungus cultivation bottle cover, and adjusting the opening area of the fungus cultivation bottle cover to partial opening to start primary fungus cultivation;

[0068] After the primary fungus cultivation, adjusting the opening area of the fungus cultivation bottle cover to the maximum to start secondary fungus cultivation.

[0069] Those skilled in the art can understand that after the above method is completed, the fungus can be scratched (the cover is removed), the mushrooms are harvested, and the classification is performed according to the needs.

[0070] In one preferred embodiment of the use of the fungus cultivation bottle in fungus culture, the fungus culture is implemented in a factory mode, that is, the fungus culture is implemented with multiple fungus cultivation bottles at the same time. In this case, during the cooling process after sterilization, the inwardly retracting structure of the middle part of the fungus cultivation bottle in the vertical direction forms a gap between the bottles, and cold air is introduced between the fungus cultivation bottles in a forced ventilation manner to accelerate the reduction of the temperature in the fungus cultivation bottle; this is particularly suitable for bottle temperature control during fungus culture.

[0071] Obviously, the fungus cultivation bottle and the fungus production line of the utility model are suitable for fungus culture.
