Description

Technical Field

[0001] The utility model relates to a liquid culture device for edible fungi, belonging to the technical field of edible fungi processing. Background Art

[0002] Edible fungi refer to mushrooms (large fungi) with large fruiting bodies and can be eaten. They are generally called mushrooms. There are more than 350 known edible fungi in China, most of which belong to the basidiomycetes. Common ones include: shiitake mushrooms, straw mushrooms, mushrooms, black fungus, white fungus, hericium, bamboo fungus, pine mushrooms (Matsutake), mushrooms, red mushrooms, ganoderma, cordyceps, truffles, lark and boletus, etc.; a few belong to the ascomycetes, including: morels, saddle mushrooms, truffles, etc. The above fungi grow in different regions and different ecological environments.

Two adjustment guide columns are symmetrically inserted on both sides of the space adjustment disk and are arranged parallel to each other between the adjustment screws. By adjusting the limit guide of the guide column and the rotation drive of the adjustment screw, the space adjustment disk is cooperatively driven to move up and down in the vertical direction to adjust the size of the culture space, so as to quickly adapt to the culture volume of different edible fungi mother species. A driving motor is fixedly installed on the top side wall of the sealing cover assembly through a motor mounting frame, and the output end of the driving motor is connected to the top end of the adjustment screw through a transmission belt. The driving motor drives the adjustment screw to rotate to adjust the size of the liquid culture space between the space adjustment disk and the sealing cover assembly.

[0007] Furthermore, the sealing cover assembly is detachably connected to the top surface of the outer culture tank body through a quick locking member, which facilitates the rapid installation and removal of the sealing cover assembly and the cleaning and disinfection of the internal components.

[0008] Furthermore, multiple layers of annular temperature regulating resistor wires are evenly arranged on the outer wall of the inner culture tank, and the temperature regulating resistor wires are electrically connected to an external power source. The temperature of the liquid culture in the inner cavity of the inner culture tank is quickly adjusted by heating the temperature regulating resistor wires, thereby improving the growth quality of the strains.

[0009] Furthermore, the adjusting screw is rotatably installed through the cover body of the sealing cover assembly via a screw mounting block, and the bottom end of the adjusting screw is rotatably connected to the bottom of the inner culture tank body.

[0011] Furthermore, a circle of sealing rubber is provided on the edge of the space regulating disk, which can ensure that the liquid culture will not leak when it is in the space above the space regulating disk.

[0012] Furthermore, an ozone generator is fixedly disposed on the bottom surface of the sealing cover assembly, and is used to generate ozone into the inner cavity of the culture tank to sterilize the miscellaneous bacteria in the tank.

[0013] Furthermore, a temperature sensor is provided on the bottom surface of the sealing cover assembly for real-time monitoring of the culture temperature in the inner cavity of the culture tank, so as to facilitate real-time adjustment of the temperature regulating resistor wire to ensure the optimum temperature for bacterial culture.

[0014] By means of the above scheme, the present invention has at least the following advantages:

[0015] (1) The ozone generator generates ozone in the inner cavity of the culture tank to sterilize the miscellaneous bacteria in the tank;

[0016] (2) According to the culture volume of the bacterial strain mother liquid, the adjusting screw (22) is driven by the driving motor (25) to rotate so as to adjust the space adjustment disk (221) to rise to a suitable height in the inner culture tank (4), so that the bacterial strain mother liquid to be cultured is in a suitable culture space;
