Description

Technical Field

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

[0002] In the edible fungi cultivation industry, the fermentation process of raw materials is a crucial step in ensuring the healthy growth of edible fungi and improving their yield and quality. High-quality fermented raw materials can provide sufficient nutrients for edible fungi and create a suitable growth environment, thereby directly affecting the final yield and economic benefits of edible fungi.

[0003] Currently, most fermentation methods involve directly piling the raw materials for edible fungi cultivation in a fermentation tank, then injecting a fermentation agent into the tank, and finally waiting for the raw materials to ferment naturally.

[0004] However, in practice, this method results in the raw materials piling up in the fermentation tank. Due to the lack of effective stirring and mixing methods, the fermenting agent is difficult to disperse evenly within the raw materials. The fermentation process varies significantly across different parts of the raw materials. Some areas may not ferment completely due to insufficient contact with the fermenting agent, while other areas may over-ferment due to excessive concentration of the fermenting agent. This uneven fermentation not only reduces the overall quality of the fermented raw materials but may also lead to uneven distribution of nutrients after fermentation, affecting the absorption and utilization of nutrients by edible fungi.

[0005] To address the above issues, a fermentation tank for raw materials used in edible mushroom cultivation has been designed. Utility Model Content

[0006] This application provides a fermentation tank for raw materials used in edible fungi cultivation, which solves the problem in related technologies where edible fungi cultivation raw materials are directly piled in the fermentation tank, then a fermentation agent is injected into the tank, and then the raw materials are left to ferment naturally, resulting in uneven fermentation.

[0007] Firstly, a fermentation tank for raw materials used in edible mushroom cultivation is provided, comprising:

[0008] A fermentation tank has a chamber for fermenting raw materials. Inside the chamber, two U-shaped grooves are arranged opposite each other. Inside the U-shaped grooves, two rotating shafts are arranged rotatably relative to each other. The rotating shafts are equipped with spiral blades and multiple stirring rods.

[0009] Two driving components are arranged opposite each other on the fermentation tank. The driving components are connected to two corresponding rotating shafts and are used to drive the corresponding rotating shafts to rotate.

[0010] The fermentation tank is equipped with a spraying mechanism, which includes a liquid supply unit on the fermentation tank and a spraying pipe inside the fermentation tank. The spraying pipe is equipped with multiple nozzles, and the liquid supply unit is used to supply fermentation agent to the spraying pipe.

[0011] The liquid supply section is equipped with a stirrer, which is used to mix the fermentation agent.

[0012] In some embodiments, the shaft is hollow inside, and two adjacent helical blades are arranged in opposite directions.

[0013] In some embodiments, the drive unit includes two bearings disposed on the fermentation tank, and the drive unit also includes a housing, a reducer disposed on one side of the housing, and a drive motor disposed on the reducer;

[0014] One end of the rotating shaft is connected to the inner side of the bearing and extends into the housing. A gear is provided on the rotating shaft inside the housing. Two adjacent gears mesh with each other. The output shaft of the drive motor is connected to the input shaft of the reducer. The output shaft of the reducer is connected to the corresponding rotating shaft.

[0015] In some embodiments, the liquid supply unit includes a tank disposed on a fermentation tank, a pump body disposed on one side of the tank body, the pump body inlet being connected to the tank body, and the pump body outlet being connected to a spraying pipe.

[0016] In some embodiments, the spraying pipe is a rectangular pipe, which is positioned above the chamber of the fermentation tank and is adapted to the fermentation tank.

[0017] The inner side of a rectangular pipe in which multiple nozzles are distributed at equal intervals.

[0018] In some embodiments, the stirrer includes a second drive motor mounted on the tank body, which rotates a rotating rod mounted inside the tank body. The rotating rod is equipped with a plurality of stirring rods, and the output shaft of the second drive motor is connected to the top end of the rotating rod.

[0019] This application provides a fermentation tank for edible fungi cultivation. The tank utilizes a drive mechanism, rotating shaft, spiral blades, and stirring rod to thoroughly mix the raw materials, ensuring rapid and uniform mixing with the fermenting agent. This increases the contact area between microorganisms and the raw materials, promotes the fermentation reaction, significantly shortens the fermentation cycle, and improves fermentation efficiency.

[0020] Fermentation agents are sprayed into the fermentation tank through the supply department, spray pipes, and nozzles. At the same time, the raw materials are stirred and turned to ensure that the fermentation conditions of the raw materials in all parts of the fermentation tank are consistent, avoiding local over-fermentation or under-fermentation. This makes the quality of the fermented raw materials more stable and the nutritional components more uniform, which is conducive to the growth and development of edible fungi and improves the yield and quality of edible fungi.

[0021] The spraying mechanism allows for adjustment of the spray volume and frequency according to actual needs, meeting the requirements of different fermentation stages and raw materials for the starter culture. The stirrer mixes the starter culture in the liquid supply section, ensuring its uniformity and avoiding waste caused by uneven starter culture composition. Attached Figure Description

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0029] This application provides a fermentation tank for raw materials used in edible fungi cultivation, which solves the problem in related technologies where edible fungi cultivation raw materials are directly piled in the fermentation tank, followed by the injection of a fermentation agent, and then the raw materials are left to ferment naturally, resulting in uneven fermentation.

[0030] Please see Figures 1-3 A fermentation tank for edible fungi cultivation includes: a fermentation tank 1, which has a chamber for fermenting raw materials. Two U-shaped grooves 11 are arranged opposite each other inside the chamber. Two rotating shafts 2 are rotatably arranged opposite each other inside the U-shaped grooves 11. Each rotating shaft 2 has a spiral blade 21 and multiple stirring rods 23. Two driving components 3 are arranged opposite each other on the fermentation tank 1. The driving components 3 are connected to the corresponding two rotating shafts 2 and are used to drive the corresponding rotating shafts 2 to rotate. A spraying mechanism 4 is provided on the fermentation tank 1. The spraying mechanism 4 includes a liquid supply section 41 on the fermentation tank 1 and a spraying pipe 42 inside the fermentation tank 1. Multiple nozzles 43 are provided on the spraying pipe 42. The liquid supply section 41 is used to supply fermenting agent to the spraying pipe 42. A stirrer 5 is provided on the liquid supply section 41 for mixing the fermenting agent.

[0031] Driven by the drive unit 3, the corresponding rotating shaft 2 rotates. When the rotating shaft 2 rotates, the spiral blades 21 and stirring rod 23 on it rotate accordingly. During the rotation, the spiral blades 21 will generate axial and radial pushing forces on the raw materials, causing the raw materials to move and roll in the fermentation tank 1. The stirring rod 23 directly stirs the raw materials, further promoting the mixing and contact between the raw materials, and ensuring that the raw materials can participate in the reaction evenly during the fermentation process.

[0032] The liquid supply unit 41 delivers the fermentation agent to the spraying pipe 42, which then sprays it evenly onto the surface of the raw materials in the fermentation tank 1 through multiple nozzles 43 evenly distributed on the spraying pipe 42. Because the stirring rod 23 and the spiral blades 21 continuously stir the raw materials, the fermentation agent sprayed onto the surface of the raw materials can quickly and evenly mix with the raw materials, increasing the contact area and reaction efficiency between the fermentation agent and the raw materials.

[0033] The stirrer 5 stirs the fermentation agent in the liquid supply section 41 to prevent the components in the fermentation agent from settling or separating, and to ensure the uniformity and stability of the fermentation agent.

[0034] The driving component 3, rotating shaft 2, spiral blade 21, and stirring rod 23 can fully stir the raw materials, enabling rapid and uniform mixing of the raw materials and fermentation agent. This increases the contact area between microorganisms and the raw materials, promotes the fermentation reaction, significantly shortens the fermentation cycle, and improves fermentation efficiency.

[0035] Fermentation agent is sprayed into fermentation tank 1 through supply unit 41, spray pipe 42 and nozzle 43, while the raw materials are stirred and turned over. This ensures that the fermentation conditions of the raw materials in all parts of fermentation tank 1 are consistent, avoiding local over-fermentation or under-fermentation. This makes the quality of the fermented raw materials more stable and the nutritional components more uniform, which is conducive to the growth and development of edible fungi and improves the yield and quality of edible fungi.

[0036] The spraying mechanism 4 allows for adjustment of the spraying volume and frequency according to actual needs, meeting the requirements of different fermentation stages and raw materials for the starter culture. The stirrer 5 mixes the starter culture in the liquid supply section 41, ensuring its uniformity and avoiding waste caused by uneven starter culture composition.

[0037] The fermentation tank has a reasonable structural design, which can adapt to the fermentation needs of different types of edible fungi cultivation raw materials with different moisture contents, and has wide applicability. Whether it is common raw materials such as sawdust and corn cobs, or some special composite raw materials, they can all be effectively fermented in this fermentation tank.

[0038] It should be noted that the fermentation agent in this implementation plan includes multiple components. Specifically, when using sawdust as raw material to cultivate bamboo fungus, the fermentation agent includes: compound fertilizer, urea, lime powder, gypsum powder, potassium dihydrogen phosphate, white sugar, water, and WY fermentation agent. The specific proportions of each component are determined according to the specific gravity of the sawdust raw material.

[0039] In this embodiment, the rotating shaft 2 is hollow inside, and the two adjacent spiral blades 21 are arranged in opposite directions.

[0040] The hollow interior of the rotating shaft 2 significantly reduces its own weight. During the operation of the fermentation tank, the rotating shaft 2 needs to rotate continuously. The hollow design reduces the mass of the rotating shaft 2, thereby reducing the energy consumption of the drive components and improving the operating efficiency of the entire fermentation system.

[0041] Meanwhile, in some cases, the hollow interior of the rotating shaft 2 can be used to house sensor wiring for monitoring the shaft's operating status, such as temperature and rotational speed. The hollow design allows these wires to be easily passed through the shaft, preventing them from being exposed and damaged.

[0042] The two adjacent spiral blades 21 are set in opposite directions. When the shaft rotates, the two spiral blades will generate thrust in different directions on the raw material. Under the action of the thrust in two directions, the raw material will form turbulence locally, thereby breaking the accumulation state of the raw material and allowing the fermentation agent to be more evenly dispersed in the raw material.

[0043] like Figure 2 As shown, in one embodiment, the driving component 3 includes two bearings 31 disposed on the fermentation tank 1. The driving component 3 also includes a housing 32, a reducer 33 disposed on one side of the housing 32, and a drive motor 34 disposed on the reducer 33. One end of the rotating shaft 2 is connected to the inner side of the bearing 31 and extends into the housing 32. A gear 35 is disposed on the rotating shaft 2 and located inside the housing 32. Two adjacent gears 35 mesh with each other. The output shaft of the drive motor 34 is connected to the input shaft of the reducer 33, and the output shaft of the reducer 33 is connected to the corresponding rotating shaft 2.

[0044] The drive motor 34 starts to run, and its output shaft transmits power to the input shaft of the reducer 33 connected to it. The reducer 33 reduces the high-speed rotational power output by the drive motor 34 and increases the torque to meet the appropriate speed and power required for the rotation of the shaft 2.

[0045] After deceleration and torque amplification, the power is output from the output shaft of the reducer 33. The reducer 33 transmits the power to the rotating shaft 2 to make it start to rotate. One end of the rotating shaft 2 is mounted on the fermentation tank 1 through the bearing 31 to ensure that the rotating shaft 2 can rotate stably and smoothly. The gears 35 on two adjacent rotating shafts 2 mesh with each other. When one rotating shaft 2 rotates under the drive of the reducer 33, the gear 35 on it will drive the gear 35 on the adjacent rotating shaft 2 that meshes with it to rotate, thereby making the adjacent rotating shaft 2 also rotate.

[0046] The two rotating shafts 2 rotate synchronously under the transmission of the gear 35, thereby driving the spiral blades 21 and stirring rods 23 set on the rotating shafts 2 to rotate, thereby realizing the stirring and mixing of the raw materials in the fermentation tank 1.

[0047] like Figure 1 and Figure 4 As shown, specifically, the liquid supply unit 41 in this embodiment includes a tank 411 installed on the fermentation tank 1, a pump body 412 installed on one side of the tank 411, the water inlet of the pump body 412 being connected to the tank 411, and the outlet of the pump body 412 being connected to the spraying pipe 42.

[0048] Tank 411 serves as a storage container for the fermentation agent. Before the fermentation tank 1 is put into operation, the fermentation agent is poured into tank 411 in an appropriate proportion.

[0049] When it is necessary to spray fermentation agent into the raw materials in fermentation tank 1, pump body 412 starts to work. The inlet of pump body 412 is connected to tank body 411. Under the action of impeller or other power components inside pump body 412, fermentation agent in tank body 411 is drawn into pump body 412. Fermentation agent drawn into pump body 412 gains a certain pressure under the action of pump body 412, and then flows out from the outlet of pump body 412 and enters spray pipe 42 connected to the outlet of pump body 412. Fermentation agent flows along spray pipe 42 and is finally evenly sprayed onto the surface of raw materials in fermentation tank 1 through multiple nozzles 43 set on spray pipe 42.

[0050] like Figure 1 and Figure 3 As shown, specifically, the spray pipe 42 is a rectangular pipe, which is set above the chamber of the fermentation tank 1 and is adapted to the fermentation tank 1; multiple nozzles 43 are distributed at equal intervals on the inner side of the rectangular pipe.

[0051] After the pump 412 delivers the fermenting agent from the tank 411 to the spray pipe 42, the fermenting agent flows along the inside of the rectangular pipe. Since the rectangular pipe is adapted to the fermentation tank 1, its shape and size can well adapt to the chamber structure of the fermentation tank 1, ensuring smooth transmission of the fermenting agent within the pipe. Multiple nozzles 43 are evenly distributed inside the rectangular pipe. When the fermenting agent flows through the nozzles 43, it is evenly sprayed in a mist onto the surface of the raw materials in the fermentation tank 1 under the pressure inside the nozzles 43. The evenly distributed nozzles 43 ensure that the fermenting agent is evenly covered in all areas of the fermentation tank 1, achieving a comprehensive spraying effect.

[0052] like Figure 4 As shown, in one embodiment, the stirrer 5 includes a second drive motor 51 mounted on a tank 411, a rotating rod 52 mounted inside the tank 411, and a plurality of stirring rods 53 mounted on the rotating rod 52. The output shaft of the second drive motor 51 is connected to the top end of the rotating rod 52.

[0053] Drive motor 51 starts running, and its output shaft directly transmits rotational power to the top of the rotating rod 52 connected to it, causing the rotating rod 52 to rotate inside the tank 411. Multiple stirring rods 53 mounted on the rotating rod 52 also rotate synchronously. During rotation, the stirring rods 53 agitate the fermentation agent inside the tank 411, causing relative movement and mixing among the various components of the fermentation agent.
