Description

Technical Field

[0001] This application relates to the field of edible fungi cultivation equipment technology, and in particular to a fermentation tank for a type of mushroom spawn. Background Technology

[0002] As a precious edible fungus that can be used for both food and medicine, the market demand for deer antler mushrooms is increasing. Its artificial cultivation technology, especially liquid spawn fermentation technology, has significant advantages in large-scale production, such as high efficiency, short cycle, high purity, and convenient inoculation. During the liquid spawn fermentation process, ensuring that the mycelium obtains sufficient dissolved oxygen, maintaining a uniform culture environment, and preventing contamination by other microorganisms are the key factors that determine the fermentation efficiency and the final quality of the spawn.

[0003] When existing general-purpose liquid fermenters are used for fermentation of *Mushroom argentea* spawn, the mycelium of *Mushroom argentea* tends to settle and accumulate at the bottom of the fermenter during the cultivation process. Traditional stirring methods often fail to thoroughly stir the sedimentation area at the bottom of the tank, resulting in a concentration and dissolved oxygen gradient between the culture medium in this area and the upper part of the tank. Due to insufficient effective oxygen supply, the mycelium in the sedimentation area experiences a decrease in metabolic activity and a significant reduction in growth and reproduction rate. In other words, existing technologies have the following technical problems: ordinary fermenters are prone to insufficient oxygen at the bottom, leading to a reduced growth rate during the fermentation of *Mammillaria pulcherrima* spawn. Therefore, a new fermenter for *Mammillaria pulcherrima* spawn is proposed to address these issues. Summary of the Invention

[0004] This embodiment provides a fermentation tank for *Agaricus esculentus* to solve the problem of reduced growth rate caused by insufficient oxygen at the bottom when fermenting *Agaricus esculentus* in ordinary fermentation tanks in the prior art.

The rotating shaft is fixedly connected to the end of the output shaft of the drive motor.

[0007] Furthermore, one end of the rotating shaft extends into the inner cavity of the fermentation tank, and a stirring tool is fixedly connected to the bottom end of the rotating shaft.

[0008] Furthermore, the gas replenishment assembly includes a linkage unit, a conveying unit, and a filtering unit. The conveying unit includes a fixed cylinder, a movable piston, and a movable guide rod. The fixed seat is fixedly installed on the outer surface of the fermentation tank. The fixed cylinder is fixedly connected to the fixed seat. The movable piston is slidably connected in the inner cavity of the fixed cylinder. One end of the movable guide rod is fixedly connected to the upper surface of the movable piston. The other end of the movable guide rod penetrates the upper wall of the inner cavity of the fixed cylinder and extends to the outside of the wall.

[0009] Furthermore, the linkage unit includes a linkage rod, a rotating disk, a connecting rod, a first bevel gear, and a second bevel gear. The linkage rod is rotatably connected to the side wall of the fermentation tank, and one end of the linkage rod extends into the inner cavity of the fermentation tank.

One end of the output hose extends to the bottom side of the inner cavity of the fermentation tank and is fixedly connected to the fermentation tank. Both the air inlet pipe and the output hose are equipped with check valves.

[0015] In order to solve the problem in the prior art that the fermentation efficiency of ordinary fermenters is easily reduced due to sedimentation at the bottom of the fermenter and lack of oxygen at the sedimentation bottom, the present application designs a stirring component and a gas supply component.

Detailed Implementation

[0019] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0020] Please see Figure 1-3 As shown, a fermentation tank for *Agaricus esculentus* spawn includes: Fermentation tank 1, with a cover 2 fixedly connected to the upper part of the fermentation tank 1; A stirring assembly 4 is fixedly installed at the cover 2, and the bottom end of the stirring assembly 4 extends into the inner cavity of the fermentation tank 1. The stirring assembly 4 is used to stir the inoculum. Gas replenishment component 5 is fixedly installed on the side wall of fermentation tank 1. Gas replenishment component 5 is used to automatically replenish gas inside fermentation tank 1 during stirring.

[0021] Through the above technical solution, by using the stirring component 4 and the gas supply component 5 together, oxygen can be automatically introduced when stirring the liquid inoculum, and the oxygen can be filtered while introducing it. This ensures oxygen supply while preventing the entry of airborne bacteria, making it particularly suitable for the fermentation and cultivation of antler mushrooms.

[0022] The stirring assembly 4 includes a support base 401, a drive motor 402, a rotating shaft 403, and a stirring tool 404. The support base 401 is fixedly disposed on the upper surface of the cover 2. The drive motor 402 is fixedly connected to the upper surface of the support base 401. The rotating shaft 403 is fixedly connected to the end of the output shaft of the drive motor 402.

[0023] One end of the rotating shaft 403 extends into the inner cavity of the fermentation tank 1, and a stirring tool 404 is fixedly connected to the bottom end of the rotating shaft 403. Through this technical solution, the rotating shaft 403 can be rotated by the operation of the drive motor 402, which in turn drives the stirring tool 404 to rotate. The rotation of the stirring tool 404 can stir the liquid bacteria inside the fermentation tank 1, making them evenly mixed.

[0024] The gas replenishment assembly 5 includes a linkage unit, a conveying unit, and a filtering unit. The conveying unit includes a fixed cylinder 505, a movable piston 506, and a movable guide rod 507. The fixed seat 504 is fixedly installed on the outer surface of the fermentation tank 1. The fixed cylinder 505 is fixedly connected to the fixed seat 504. The movable piston 506 is slidably connected in the inner cavity of the fixed cylinder 505. One end of the movable guide rod 507 is fixedly connected to the upper surface of the movable piston 506. The other end of the movable guide rod 507 passes through the upper wall of the inner cavity of the fixed cylinder 505 and extends to the outside of the wall.

[0025] The linkage unit includes a linkage rod 501, a rotating disk 502, a connecting rod 503, a first bevel gear 512, and a second bevel gear 513. The linkage rod 501 is rotatably connected to the side wall of the fermentation tank 1, and one end of the linkage rod 501 extends into the inner cavity of the fermentation tank 1.

[0026] One end of the linkage rod 501 is fixedly connected to a first bevel gear 512, and the second bevel gear 513 is fixedly disposed at the arc-shaped wall of the rotating shaft 403. The first bevel gear 512 and the second bevel gear 513 mesh with each other. Through this technical solution, when the rotating shaft 403 is rotated by the operation of the drive motor 402, the second bevel gear 513 can be rotated, thereby driving the first bevel gear 512 to rotate, and then driving the linkage rod 501 to rotate.

[0027] A rotating disk 502 is fixedly connected to the side wall of the linkage rod 501. One end of a connecting rod 503 is rotatably connected to the side wall of the rotating disk 502. The other end of the connecting rod 503 is rotatably connected to the top end of the moving guide rod 507. Through this technical solution, the rotation of the rotating disk 502 can drive one end of the connecting rod 503 to move in a circular motion, thereby driving the bottom end of the connecting rod 503 to move up and down reciprocally, which in turn drives the moving guide rod 507 to move up and down reciprocally, so that the moving piston 506 moves reciprocally within the cavity of the fixed cylinder 505.

[0028] Specifically, the linkage rod 501 rotatably passes through the side wall of the fermentation tank 1 via a bearing assembly. An axial seal is provided between the bearing assembly and the linkage rod 501 to ensure a sterile environment inside the fermentation tank 1. The rotating disk 502 is eccentrically fixed to the outer end of the linkage rod 501, and its eccentricity is 1 / 4 to 1 / 2 of the stroke length of the connecting rod 503. The two ends of the connecting rod 503 are respectively connected to the rotating disk 502 and the moving guide rod 507 through ball joints. The filtration unit includes a filter housing 508, a filter element 509, an air inlet pipe 510, and an output hose 511. The filter housing 508 is fixedly connected to and communicates with the bottom end of the fixed cylinder 505. The filter element 509 is fixedly disposed in the inner cavity of the filter housing 508. The filter element 509 is a hydrophobic PTFE microporous membrane with a filtration accuracy of 0.2μm, and it is detachably snapped into an annular groove in the inner cavity of the filter housing 508. An air inlet pipe 510 and an output hose 511 are fixedly connected to the inner cavity of the filter shell 508. One end of the output hose 511 extends to the bottom side of the inner cavity of the fermentation tank 1 and is fixedly connected to the fermentation tank 1. Both the air inlet pipe 510 and the output hose 511 are equipped with check valves. With this technical solution, when the moving piston 506 reciprocates in the inner cavity of the fixed cylinder 505, the upward movement of the moving piston 506 can draw in external gas, which is then filtered and sterilized by the filter element 509. The downward movement of the moving piston 506 allows the filtered gas to be output through the output hose 511 and injected into the bottom of the inner cavity of the fermentation tank 1. This allows for the automatic replenishment of oxygen to the sedimentation area while stirring, thereby improving fermentation efficiency.
