[0002] Deer antler mushrooms are a highly nutritious type of mushroom, rich in protein, vitamins, and other nutrients. Cultivation of deer antler mushrooms requires the development of microbial strains, which necessitates the use of fermentation tanks to provide the spawn for production.

[0003] A patent website discloses a fermentation tank for *Mushroomria cirrhosa* spawn (publication number: CN219217959U), comprising: an insulated tank with a top hole at its top, into which a fermentation tank is tightly contacted; the fermentation tank contains *Mushroomria cirrhosa* spawn liquid; a steam inlet pipe, a steam outlet pipe, and a water pipe are fixedly installed at the top of the fermentation tank; a temperature sensor is fixedly installed on the inner wall of the top of the fermentation tank; and a feed pipe is fixedly installed at the bottom of the fermentation tank; and a heating and stirring assembly is installed on the insulated tank and the fermentation tank. This invention has the following advantages and effects: it can maintain a suitable temperature inside the fermentation tank at low temperatures, ensuring normal fermentation of the *Mushroomria cirrhosa* spawn liquid; and it can stir the *Mushroomria cirrhosa* spawn liquid inside the fermentation tank, thus improving the fermentation efficiency.

[0004] The above technology has the following problems in use: 1. Heating is carried out by rotating the fermenter and heating the tube, but the heating effect is not uniform and ideal. 2. It is not convenient to inject air into the antler mushroom spawn, thus reducing the fermentation efficiency. Therefore, there is room for improvement. Utility Model Content

[0005] This invention provides a liquid fermentation tank for *Agaricus esculentus* spawn, to solve the problems mentioned in the background.

[0006] The problems raised in the technology.

[0007] To address the aforementioned problems, this utility model provides a liquid fermentation tank for *Agaricus esculentus*, comprising an insulated tank, a fermentation tank, and a stirring mechanism. The fermentation tank is installed within the insulated tank, forming a heating chamber between them. Several heating rods are evenly spaced within the heating chamber. A water inlet pipe communicating with the heating chamber is located on the upper side of one side of the insulated tank, and a drain pipe communicating with the heating chamber is located on the lower side of the other side of the insulated tank. A sealing cap is installed on the top of the insulated tank to seal the top of the fermentation tank. The stirring mechanism is located inside the fermentation tank and connected to the sealing cap. The stirring mechanism consists of a stirring shaft, an air inlet pipe, and a scraper. The top end of the stirring shaft rotatably passes through the sealing cap and extends beyond the top part of the sealing cap. The unit is equipped with a first gear, the top of the stirring shaft is equipped with a connecting end, and the top of the stirring shaft is equipped with an air inlet chamber. The upper part of the stirring shaft located inside the fermentation tank is connected to an annular pipe that communicates with the air inlet chamber. The bottom of the stirring shaft is connected to a cross-shaped support frame. The scraper consists of four symmetrically fixed ends connected to the support frame away from the stirring shaft, and the scraper abuts against the inner wall of the fermentation tank. The air inlet pipe consists of four pipes with their bottom ends fixed in the support frame and their top ends connected to the annular pipe. The top of the sealing cover is equipped with a motor, and the output end of the motor is equipped with a second gear that meshes with the first gear. The outside of the heat preservation tank is equipped with a controller, and the controller is connected to the heating rod, the motor, the water inlet pipe, and the drain pipe.

[0008] Preferably, one side of the sealing cap is provided with a feed inlet that connects to the fermentation tank, and a sealing plug is installed in the feed inlet.

[0009] Preferably, an exhaust pipe communicating with the inside of the fermentation tank is installed in the sealing cover, and a pressure gauge is installed at the middle end of the exhaust pipe outside the sealing cover, and the exhaust pipe and the pressure gauge are respectively connected to the controller.

[0010] Preferably, the air intake pipe is provided with several air vents at equal intervals.

[0011] Preferably, a fixing plate is installed between the scraper and the corresponding air intake pipe.

[0012] The beneficial effects of adopting the above technical solutions are:

[0013] Air is introduced through the connection end of the stirring shaft, and the air is introduced into the fermenter through the air inlet chamber in conjunction with the annular pipe and the air inlet pipe. Since the air vents are equidistantly arranged in the air inlet pipe, the air can be fully introduced into the inoculum to promote fermentation.

[0014] When the air pressure inside the fermenter is too high, the pressure gauge on the exhaust pipe is set to facilitate the removal of internal air and ensure the stability of fermentation.

[0015] Water is introduced into the heating chamber through the inlet pipe and heated by the heating rod. Since the fermentation tank is in full contact with water, the heating stability can be ensured and the fermentation effect can be improved. When cooling is required, hot water is drained through the drain pipe and cold water is gradually introduced through the inlet pipe to cool the fermentation tank.

[0016] The motor drives the second gear, which in turn drives the first gear to rotate, causing the stirring shaft to rotate. This, in turn, causes the support frame to rotate, and simultaneously the air inlet pipe and scraper to rotate, thus stirring the inoculum. The scraper can effectively scrape off the inoculum adhering to the inner wall of the fermenter, ensuring the fermentation effect and facilitating subsequent cleaning of the fermenter.

[0025] like Figure 1-4 In this embodiment, a liquid fermentation tank for *Agaricus esculentus* includes an insulated tank 1, a fermentation tank 2, and a stirring mechanism 3. The fermentation tank 2 is installed inside the insulated tank 1, and a heating chamber 4 is formed between the fermentation tank 2 and the insulated tank 1. Several heating rods 41 are evenly spaced within the heating chamber 4. A water inlet pipe 11 communicating with the heating chamber 4 is located on one side of the insulated tank 1, and a drain pipe 12 communicating with the heating chamber 4 is located on the other side of the insulated tank 1.

The stirring mechanism 3 is located inside the fermentation tank 2 and connected to the sealing cover 5. The stirring mechanism 3 consists of a stirring shaft 31, an air inlet pipe 32, and a scraper 33. The top end of the stirring shaft 31 rotates through the sealing cover 5, and a first gear 34 is provided outside the top end of the sealing cover 5. The top end of the shaft 31 is provided with a connecting end 35, and the interior of the top end of the stirring shaft 31 is provided with an air inlet chamber 36. The upper part of the stirring shaft 31 located inside the fermentation tank 2 is connected to an annular pipe 37 that communicates with the air inlet chamber 36.

The outside of the heat preservation tank 1 is provided with a controller 6, and the controller 6 is connected to the heating rod 41, the motor 51, the water inlet pipe 11, and the drain pipe 12 respectively.

[0026] Through the above technical solution, the inoculum to be fermented is fed into the fermenter 2 and sealed by the sealing cap 5. The motor 51 drives the second gear 52 to rotate the meshing first gear 34, causing the stirring shaft 31 to rotate. This, in conjunction with the support frame 38, scraper 33, and air inlet pipe 32, performs stirring.

[0031] Preferably, the air intake pipe 32 is provided with a plurality of air vents 321 at equal intervals.

[0032] Through the above technical solution, the setting of the vent 321 prevents the bacterial liquid from being introduced into the air inlet pipe 32, while facilitating the entry of air into the bacterial liquid.

[0033] Preferably, a fixing plate 39 is installed between the scraper 33 and the corresponding air intake pipe 32.

[0034] Through the above technical solution, the setting of the fixing plate 39 facilitates the stability of the scraper 33 in operation, while also playing a stirring role.
