Description

Technical Field

[0001] This utility model relates to the field of edible fungi fermentation technology, specifically to a liquid edible fungi fermentation tank. Background Technology

[0002] Edible mushroom factories generally use liquid fermentation spawn production technology, which employs a whole-body sterilization method and utilizes the principle of biological fermentation. Through the liquid spawn fermentation tank, the mycelium is provided with optimal nutrition, pH, temperature, and oxygen supply, enabling the mycelium to grow rapidly and multiply quickly, reaching a certain number of mycelial balls in a short period of time to complete a fermentation cycle.

[0003] The existing aeration devices for liquid spawn fermentation tanks for edible fungi are generally located at the bottom of the tank. Compared with the spawn in the upper layer, the aeration effect is relatively poor, which leads to uneven aeration and affects the production and reproduction of edible fungi. Therefore, a liquid spawn fermentation tank for edible fungi is proposed to address the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a liquid spawn fermentation tank for edible fungi to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A liquid spawn fermentation tank for edible fungi includes a fermentation tank and a support base. The support base is fixedly connected to the bottom end of the fermentation tank, and a fixed plate is fixedly connected to the bottom end of the fermentation tank. An inner shell is fixedly connected to the inner side of the fermentation tank, and an aeration groove is formed between the fermentation tank and the inner shell. A one-way valve is fixedly connected inside the inner shell. A partition layer located inside the inner shell is fixedly connected to the inner side of the fermentation tank, and a water inlet groove is formed inside the partition layer. A hydraulic rod penetrating the fixed plate is fixedly connected to the top end of the support base, and a push plate located inside the partition layer is fixedly connected to the top end of the hydraulic rod. A sealing rubber layer that fits against the partition layer is fixedly connected to the outer side of the push plate. Holes are formed at the top ends of the push plate and the sealing rubber layer. A pressure relief valve is fixedly connected to the top end of the fermentation tank. Air inlet pipes penetrating the fermentation tank are fixedly connected to both sides of the fermentation tank. A water inlet valve connected in a continuous manner is fixedly connected to the bottom end of the fixed plate, and a drain valve connected in a continuous manner is fixedly connected to the right side of the water inlet valve at the bottom end of the fixed plate.

[0007] Preferably, there are four water inlet tanks, which are symmetrically arranged on the surface of the partition layer with the center of the partition layer as the center.

[0008] Preferably, the number of holes is several, and the holes are evenly arranged in a matrix inside the push plate and the sealing rubber layer.

[0009] Preferably, there are several one-way valves, which are arranged in a matrix uniformly inside the inner shell with the center of the inner shell as the center.

[0010] Preferably, the inner shape of the separator layer matches the outer shape of the sealing rubber layer, and the inner side of the separator layer and the outer side of the sealing rubber layer are in contact with each other.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. In this utility model, the inner shell, aeration tank, one-way valve, partition layer, water inlet tank, push plate, sealing rubber layer, holes and hydraulic rod are designed to drive the liquid microbial culture in the fermentation tank to circulate. Aeration is achieved through one-way valves at different positions, which allows the liquid microbial culture to fully mix and contact with the aeration, making the fermentation of the liquid microbial culture more efficient and stable. This solves the problem that the existing aeration devices of edible fungi liquid microbial culture fermentation tanks are generally located at the bottom of the tank, and the aeration effect is relatively poor compared to the upper layer of microbial culture, which leads to uneven aeration and affects the production and reproduction of edible fungi.

[0013] 2. In this utility model, the sealing rubber layer effectively improves the pushing efficiency of the edible fungus liquid, allowing the edible fungus liquid to circulate more efficiently. The pressure relief valve can discharge excess pressure in the fermenter, avoiding excessive aeration and the risk of explosion. The multiple sets of holes allow the fungal liquid to pass through the push plate and the sealing rubber layer and return to the push plate surface, facilitating the next circulation of the fungal liquid in the fermenter.

[0021] Please see Figure 1-3 This utility model provides a technical solution:

[0022] A liquid spawn fermentation tank for edible fungi includes a fermentation tank 1 and a support base 2. The support base 2 is fixedly connected to the bottom end of the fermentation tank 1, and a fixing plate 3 is fixedly connected to the bottom end of the fermentation tank 1. An inner shell 4 is fixedly connected to the inner side of the fermentation tank 1. An aeration groove 5 is provided between the fermentation tank 1 and the inner shell 4. A one-way valve 6 is fixedly connected inside the inner shell 4. A partition layer 7 located inside the inner shell 4 is fixedly connected to the inner side of the fermentation tank 1. A water inlet groove 8 is provided inside the partition layer 7. A hydraulic rod 9 penetrating the fixing plate 3 is fixedly connected to the top of the support base 2. The top of the pressure rod 9 is fixedly connected to a push plate 10 located inside the partition layer 7. The outer side of the push plate 10 is fixedly connected to a sealing rubber layer 11 that fits into the partition layer 7. The top of the push plate 10 and the sealing rubber layer 11 are provided with holes 12. The top of the fermentation tank 1 is fixedly connected to a pressure relief valve 13. The two sides of the fermentation tank 1 are fixedly connected to an air inlet pipe 14 that penetrates the fermentation tank 1. The bottom of the fixed plate 3 is fixedly connected to a water inlet valve 15 that is connected in a continuous manner. The bottom of the fixed plate 3 is fixedly connected to a drain valve 16 located to the right of the water inlet valve 15 that is connected in a continuous manner.

[0023] There are four water inlet tanks 8, which are symmetrically arranged on the surface of the partition layer 7 with the center of the partition layer 7 as the center. This allows the bacterial solution to enter the space between the inner shell 4 and the partition layer 7 more efficiently, making it easier for the bacterial solution to mix evenly. There are several holes 12, which are evenly arranged in a matrix inside the push plate 10 and the sealing rubber layer 11. This allows the bacterial solution to quickly return to the surface of the push plate 10, making it easier to push the bacterial solution to circulate and mix again. There are several one-way valves 6, which are evenly arranged in a matrix inside the inner shell 4 with the center of the inner shell 4 as the center. This can improve the contact effect between external aeration and bacterial solution. The inner shape of the partition layer 7 matches the outer shape of the sealing rubber layer 11, and the inner side of the partition layer 7 and the outer side of the sealing rubber layer 11 fit together.

[0024] Workflow: When a liquid edible fungus fermentation tank is needed, the entire system is powered externally and pressurized by an external hydraulic pump. First, the inlet valve 15 is opened to inject the liquid to be fermented into the fermentation tank 1. After entering, the inlet valve 15 is closed, and the bacterial liquid will flow through the holes 12 to the top of the push plate 10. The hydraulic rod 9 pushes the push plate 10 and the sealing rubber layer 11 upward. The rapid upward movement of the sealing rubber layer 11, even with holes 12 on its surface, will push the bacterial liquid into the inlet tank 8. At this time, under the action of the air inlet pipe 14 and the aeration tank 5, the external... Aeration is evenly introduced between the inner shell 4 and the partition layer 7 through multiple sets of one-way valves 6, allowing the aeration to fully contact the bacterial liquid. The bacterial liquid flows evenly from top to bottom, further improving the contact effect between the bacterial liquid and the external aeration. Afterwards, the bacterial liquid will return to its original position from the bottom of the partition layer 7 under the action of gravity, and the push plate 10 will also be reset under the action of the hydraulic rod 9. The bacterial liquid will return to the push plate 10 and the sealing rubber layer 11 through the hole 12, simultaneously achieving a more uniform mixing effect of the bacterial liquid. After fermentation is completed, the drain valve 16 is opened to discharge the fermented edible bacterial liquid, completing the collection.
