[0002] Fungal fermentation culture is a process that uses fermentation technology to promote the growth and reproduction of fungi, aiming to promote the synthesis of required products by fungi through specific culture conditions. The fermentation products synthesized by fungi have the effect of killing pests, so they are often used in the field of biological control. Fermentation tanks and other equipment are used in the preparation of fungal fermentation products. By putting culture media in the fermentation tank, an environment for the growth, reproduction and synthesis of products can be provided for fungal strains to accelerate the growth of fungi and promote the synthesis of fermentation products.
[0003] When the existing biocontrol fungal fermentation culture equipment is in use, in order to provide a warm and humid environment for fungi, the staff will use a heating jacket arranged outside the fermentation tank to heat the tank body.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0025] Please refer to Figures 1-7 As shown, a biocontrol fungal fermentation and culture device includes a fermentation tank body 1. A heating jacket 2 is fixedly connected to the outside of the fermentation tank body 1. A plurality of support columns 4 are symmetrically installed at the bottom of the heating jacket 2. Anti-slip foot pads 5 are fixedly connected to the bottom ends of the support columns 4. As Figure 1 shown, by setting the anti-slip foot pads 5, the contact area between the support columns 4 and the ground can be increased, and at the same time, the friction between the support columns 4 and the ground is enhanced, so that the fermentation tank body 1 is placed more stably and is less likely to be toppled by external forces; a sealing top cover 3 adapted to the inner cavity of the fermentation tank body 1 is provided at the top of the inner cavity of the fermentation tank body 1. It further includes: a sealing assembly 14 provided outside the sealing top cover 3 for preventing the leakage of gas inside the fermentation tank body 1. By setting the sealing assembly 14, during the fungal fermentation and culture process, the leakage of gas inside the fermentation tank body 1 can be prevented from polluting the experimental environment, and at the same time, external germs can be prevented from entering the inside of the fermentation tank body 1 to affect the growth of fungi; a shaft sleeve 8 is coaxially and vertically installed at the top of the sealing top cover 3, and a transmission shaft 9 is rotatably connected inside the shaft sleeve 8; a stirring assembly 10 provided outside the transmission shaft 9 for fully mixing the fungal strains and the culture medium. By setting the stirring assembly 10, the fungal strains and the culture medium can be fully mixed, providing a favorable environment for the growth, reproduction and product synthesis of the fungal strains; a heat preservation assembly 6 for slowing down the heat loss rate inside the fermentation tank body 1 is provided inside the heating jacket 2. By setting the heat preservation assembly 6 and cooperating with the stirring assembly 10, heating can be achieved simultaneously from the inner wall of the fermentation tank body 1 to the center side and from the center of the fermentation tank body 1 to the inner wall side, so that the temperatures of the fungal strains at various positions inside the fermentation tank body 1 can be uniformized, thereby improving the fermentation efficiency and fermentation effect of the fungi and making the output of the fungal fermentation product more sufficient.
[0026] The sealing assembly 14 includes a sealing ring 143 provided outside the sealing top cover 3. Flange plates 141 are fixedly connected to the top of the fermentation tank body 1 and the bottom of the sealing top cover 3. Sealing grooves 142 are opened on one side of the two flange plates 141 close to each other. The sealing ring 143 is located inside the sealing groove 142. As Figure 4 、 Figure 5 shown, by setting the sealing ring 143, the sealing performance between the fermentation tank body 1 and the sealing top cover 3 is improved, thereby preventing the leakage of gas inside the fermentation tank body 1 and at the same time preventing external germs from entering the inside of the fermentation tank body 1.
[0027] The stirring assembly 10 includes a U-shaped frame 102 fixed to the top of the sealed top cover 3. A driving motor 101 is fixedly installed at the top of the U-shaped frame 102. The top end of the transmission shaft 9 penetrates through the U-shaped frame 102 and is connected to the output end of the driving motor 101. There are no less than two L-shaped rods 105 provided around the bottom end of the transmission shaft 9. A plurality of stirring paddle plates 103 are provided between the L-shaped rods 105 and the transmission shaft 9. A plurality of spoiler holes 104 are symmetrically formed on each stirring paddle plate 103. As Figure 7 shown, by providing the spoiler holes 104, the flow direction of the materials inside the fermentation tank 1 is disrupted, enabling the fungal strains to be fully mixed with the culture medium, which is more conducive to the production of fermentation products; the stirring paddle plates 103 are respectively connected to the L-shaped rods 105 and the transmission shaft 9. A scraper 106 is fixedly connected to the side of the L-shaped rod 105 away from the stirring paddle plate 103. One side of the scraper 106 is in contact with the inner wall of the fermentation tank 1. As Figure 4 , 6 shown, by using the driving motor 101 to drive the multiple groups of stirring paddle plates 103 at the bottom end of the transmission shaft 9 to rotate simultaneously, the scraper 106 on the outside of the L-shaped rod 105 will scrape off the residual materials on the inner wall of the fermentation tank 1 during the stirring process. The scraped-off materials will re-participate in the stirring work, thus further improving the mixing degree of the fungal strains and the culture medium.
[0028] A temperature control switch 13 is fixedly installed at the top of one side of the sealed top cover 3. A conductive slip ring 12 is provided on the outside of the top end of the transmission shaft 9. The conductive slip ring 12 is fixedly installed on the U-shaped frame 102. A cable through groove 15 for facilitating the penetration of wires is provided inside the transmission shaft 9. An electric heating strip 11 is fixedly installed inside each stirring paddle plate 103. The electric heating strip 11 is connected in series with the wiring terminal of the temperature control switch 13 through a wire. The temperature control switch 13 is connected to the output end of the conductive slip ring 12 through a wire. As Figure 3 , Figure 4 , Figure 7 shown, during actual use, an external power supply is connected to the input end of the conductive slip ring 12 through a wire to provide power for it. When the stirring assembly 10 performs the mixing work of the fungal strains and the culture medium, the wire connected to the electric heating strip 11 will penetrate out of the cable through groove 15 and rotate together with the conductive slip ring 12. In this way, while ensuring that the temperature control switch 13 controls the electric heating strip 11, the wire will not be broken due to the rotational force of the driving motor 101.
[0029] The heat preservation assembly 6 includes a spiral liquid pipe 62 fixed to the outer wall of the fermentation tank 1. One end of the spiral liquid pipe 62 penetrates to the outside of the heating jacket 2 and is provided with a liquid inlet 63. The other end of the spiral liquid pipe 62 penetrates to the outside of the heating jacket 2 and is provided with a liquid outlet 64. A heat insulation layer 61 is provided on the outside of the spiral liquid pipe 62. The heat insulation layer 61 is made of fiberglass or ceramic fiber material. As Figure 3As shown, by setting the liquid inlet 63 and the liquid outlet 64, it can be connected to an external heating medium pipe, so as to achieve heating from the inner wall of the fermentation tank body 1 to the center side. Then, the heat insulation layer 61 can slow down the heat exchange rate between the inside and outside of the heating jacket 2 and reduce heat loss.
[0030] At the bottom of the inner cavity of the fermentation tank body 1, there is a discharge port 7. On one side of the sealed top cover 3, a fungal inoculation port 16 and a culture medium inoculation port 17 are respectively arranged at the top. Solenoid valves are installed inside the fungal inoculation port 16, inside the culture medium inoculation port 17, and inside the discharge port 7. As Figure 4 shown, by setting the fungal inoculation port 16 and the culture medium inoculation port 17, it is convenient to inoculate the fungal strains and the culture medium. Then, by using the discharge port 7, it is convenient to discharge the fungal fermentation product.
[0031] On one side of the top of the fermentation tank body 1, a pressure gauge 19 is fixedly installed. The detection end of the pressure gauge 19 penetrates into the inside of the fermentation tank body 1. On the other side of the top of the fermentation tank body 1, a pressure relief valve 18 is provided. As Figure 1 、 Figure 2 shown, through the pressure gauge 19, it is convenient for the staff to observe the pressure change inside the fermentation tank body 1. When the pressure inside the fermentation tank body 1 is too high, the excess gas can be discharged through the pressure relief valve 18, so as to avoid generating a high-pressure environment inside the fermentation tank body 1. In addition, since the pressure relief valve 18 is pre-connected to an external gas discharge pipe, it can prevent the contaminated gas from directly discharging and polluting the experimental environment.
[0032] Working principle: First, the staff uses the fungal inoculation port 16 and the culture medium inoculation port 17 to put the fungal strains and the culture medium into the inside of the fermentation tank body 1. Then, the fungal strains and the culture medium are fully mixed by the stirring assembly 10 to provide a favorable environment for the growth, reproduction, and product synthesis of the fungal strains. Then, in cooperation with the heat preservation assembly 6, heating can be achieved simultaneously from the inner wall of the fermentation tank body 1 to the center side and from the center of the fermentation tank body 1 to the inner wall side, so that the temperature of the fungal strains at each position inside the fermentation tank body 1 can be uniformized. In this way, the fermentation efficiency and fermentation effect of the fungus are improved, and the output of the fungal fermentation product is more sufficient.
