[0011] Based on the above technical solution, a fermentation method of a liquid fermentation device for Armillaria liquid mycelium powder comprises the following steps: Step 1: Close the electric valve of the discharge barrel, then open the electric valve of the feed barrel, connect the exhaust barrel to the external gas treatment system, connect the air inflation pipe to the external sterile air inflation system, use the sterile air inflation system to continuously fill the tank with air of the required temperature, and then send the raw materials to be fermented into the tank through the feed barrel. As the raw materials accumulate to a certain volume, close the electric valve of the feed barrel. The injected air can agitate the raw materials, so that the raw materials come into contact with and mix with the oxygen in the air, and then the air is discharged from the exhaust barrel. In this process, under the elastic force of the elastic member, the upper sliding plate and the lower sliding plate are moved away from the inner wall of the tank, so that the No. 1 scraper and the No. 3 scraper do not contact the inner wall of the tank; Step 2: Control the electric drive rotation mechanism and the lifting mechanism so that the upper and lower air guide covers are both located in the raw material, while preventing the upper and lower sliding plates from pressing against each other, and rotating along with the main stirring shaft and the auxiliary stirring shaft, thereby stirring and mixing the raw material and air; Step 3: By controlling the movement of the lifting mechanism, the upper and lower air guide covers are positioned above the air blast pipe, so that when the air is floating upward, a portion of the air is gathered by the lower air guide cover and discharged through the through hole, and then dispersed by the upper air guide cover, and discharged from the gap between the upper air guide cover and the inner wall of the tank, and finally discharged from the exhaust pipe, thereby extending the contact time of the incoming sterile air with the raw materials and the contact area during the flow process; Step 4: Stir the raw materials thoroughly so that the air is fully mixed with the raw materials for a period of time. After the fermentation is completed, open the electric valve at the bottom of the discharge barrel to discharge the fermented materials. The cam is moved up and down to move the upper and lower guide hoods together, so that the upper and lower sliding plates are moved closer to each other and squeezed against each other, and then the upper sliding plate overcomes the elastic force of the elastic member to slide outward and upward, so that the lower sliding plate overcomes the elastic force of the elastic member to slide outward and downward, so that the first scraper can fit the inner wall of the tank body, and the third scraper can fit the inner wall of the tank body. Then, the upper and lower guide hoods are moved up and down and rotated together to clean the inner wall of the tank body. When moving to the lower part of the tank body, the third scraper and the fourth scraper can be used to clean the bottom end of the inner wall of the tank body. When moving to the upper part of the tank body, the first scraper and the second scraper can be used to clean the top end of the inner wall of the tank body. During the cleaning process, cleaning liquid is introduced into the feed barrel into the tank body, and then discharged through the discharge barrel, thereby removing the dirt generated by cleaning.

[0012] Compared with the prior art, the present invention has the following advantages: the present invention utilizes elastic parts and a lifting mechanism to ensure that the No. 1 scraper and the No. 3 scraper do not contact the inner wall of the tank during the stirring process, but can be controllably contacted with the inner wall of the tank during the cleaning process, and the inner wall of the tank can be cleaned under the drive of the electric drive rotating mechanism, thereby reducing wear and the impact on the material. The upper guide cover, the lower guide cover, the toggle plate and the through hole can also be used to guide the sterile air entering the tank during the stirring of the material, thereby extending the contact time of the entering sterile air with the raw materials and the contact area during the flow process, thereby improving the utilization rate of the sterile air and the fermentation efficiency.

[0013] The temperature of the sterile air flowing through it is detected in real time by multiple temperature sensors, and then the corresponding solenoid valve No. 1 is controlled to be turned on, so that the temperature control of the sterile air entering the tank body is more precise, thereby ensuring the fermentation efficiency. The horizontally eccentrically arranged air pipe enables the sterile air to push the material to rotate after entering the tank body, thereby increasing the contact time and contact area between the sterile air and the material, promoting stirring and mixing, and making the material heated more evenly, thereby improving the utilization rate of the sterile air.

[0014] The extension mechanism can be used to conveniently adjust the position of the extension tube, and the extension tube inserted into the tank body allows the sterile air to better push the material in the tank body, reducing premature loss of volume and improving utilization.

The temperature of the sterile air flowing through it is detected in real time through multiple temperature sensors 47, and then the corresponding No. 1 solenoid valve 45 is controlled to be turned on, so that the temperature control of the sterile air entering the tank body 1 is more precise, thereby ensuring the fermentation efficiency. The horizontally eccentrically arranged air pipe 5 enables the sterile air to push the material to rotate after entering the tank body 1, thereby increasing the contact time and contact area between the sterile air and the material, promoting stirring and mixing, and making the material heated more evenly, thereby improving the utilization rate of the sterile air.

[0033] The heater includes a water tank 49, a water outlet pipe 50, and a water inlet pipe 51. The top of the water tank 49 is fixedly connected to the water outlet pipe 50, and the bottom is fixedly connected to the water inlet pipe 51. The water inlet pipe 51 is connected to the external hot water supply system, and the water outlet pipe 50 is connected to the external water treatment system. Insulation layers 52 are respectively provided inside the water tank 49, inside the tank body 1, and outside the multi-way pipe rack 41.

[0034] Furthermore, by supplying hot water to the water inlet pipe 51 and discharging the water after heat exchange with the spiral heat exchange tube 38 through the water outlet pipe 50, the sterile air in the spiral heat exchange tube 38 can be heated, and the thermal energy utilization rate is higher, and the insulation layer 52 can reduce the loss of heat energy.

[0035] The fermentation device includes an extension mechanism, and the extension structure includes a cylinder 53, an air pressure sensor 54, an input pipe 55, a second solenoid valve 56, a piston 57, an extension pipe 58, and a limiting ring 59. The outer walls of the two output pipes 44 are respectively fixed with cylinders 53, the cylinder 53 is fixed with an air pressure sensor 54, and is fixedly connected with the input pipe 55. The middle part of the input pipe 55 is fixed with a second solenoid valve 56, and the second solenoid valve 56 is used to control whether the input pipe 55 is conductive. The inner wall of the cylinder 53 and the outer wall of the output pipe 44 are jointly sealed and slidably connected with a piston 57, and the piston 57 is fixed with a horizontal extension pipe 58. The sensor 54 is used to measure the air pressure in the space formed by the cylinder body 53, the output pipe 44 and the piston 57. The extension pipe 58 is inserted into the outside of the output pipe 44. The cylinder body 53 is fixedly connected to the air blower pipe 5. A limit ring 59 is fixed at the transition between the cylinder body 53 and the air blower pipe 5. The limit ring 59 is used to prevent the piston 57 from detaching from the cylinder body 53. The air pressure sensor 54 and the No. 2 solenoid valve 56 are electrically connected to the electronic control system. A one-way valve 64 is fixed in the extension pipe 58 and can be inserted into the tank body 1. The one-way valve 64 only allows gas to flow into the tank body 1. The input pipe 55 is connected to the external sterile air supply system.

[0036] Furthermore, the cylinder 53 is first inflated by the sterile air supply system, so that the piston 57 moves toward the limit ring 59 under the action of the air pressure difference, and then the extension tube 58 can be inserted into the tank body 1. Then the second solenoid valve 56 is closed and sterile air is filled into the tank body 1. The air pressure fluctuation in the cylinder 53 is detected by the air pressure sensor 54, and sterile air is injected into the cylinder 53 in time to ensure that the position of the extension tube 58 remains unchanged. At this time, the extension tube 58 inserted into the tank body 1 makes the sterile air The air can better push the material in the tank body 1 and reduce the volume lost in advance. When the inner wall of the tank body 1 needs to be cleaned, the No. 2 solenoid valve 56 is controlled to be turned on, and the piston 57 can drive the extension tube 58 away from the tank body 1 under the action of the air pressure difference between the tank body 1 and the cylinder body 53, that is, the extension tube 58 is retracted into the cylinder body 53, thereby facilitating the subsequent cleaning of the inner wall of the tank body 1 by the No. 1 scraper 17 and the No. 3 scraper 19. The one-way valve 64 can prevent the material from flowing into the input pipe 55.

[0037] A fermentation method of a liquid fermentation device for Armillaria liquid mycelium powder, comprising the following steps: Step 1: Close the electric valve 6 of the discharge barrel 4, then open the electric valve 6 of the feed barrel 2, connect the exhaust barrel 3 to the external gas treatment system, connect the air inflation pipe 5 to the external sterile air inflation system, use the sterile air inflation system to continuously fill the tank body 1 with air of the required temperature, and then send the raw materials to be fermented into the tank body 1 through the feed barrel 2. As the raw materials accumulate to a certain volume, close the electric valve 6 of the feed barrel 2. The injected air can agitate the raw materials, so that the raw materials come into contact with and mix with the oxygen in the air, and then the air is discharged from the exhaust barrel 3. In this process, under the elastic force of the elastic member, the upper sliding plate 14 and the lower sliding plate 15 are moved away from the inner wall of the tank body 1, so that the No. 1 scraper 17 and the No. 3 scraper 19 do not contact the inner wall of the tank body 1; Step 2: Control the electric drive rotation mechanism and the lifting mechanism so that the upper guide cover 11 and the lower guide cover 12 are both located in the raw material, while preventing the upper sliding plate 14 and the lower sliding plate 15 from pressing each other, and rotate along with the main stirring shaft 9 and the auxiliary stirring shaft 10, so as to stir and mix the raw material and air; Step 3: By controlling the movement of the lifting mechanism, the upper shroud 11 and the lower shroud 12 are positioned above the air blast pipe 5. This allows the air to be partially gathered by the lower shroud 12 during the upward movement and then discharged through the through-hole 21. The air is then dispersed by the upper shroud 11 and discharged from the gap between the upper shroud 11 and the inner wall of the tank body 1, and finally discharged from the exhaust pipe 3. This prolongs the contact time between the incoming sterile air and the raw materials and the contact area during the flow process. Step 4: Stir the raw materials thoroughly so that the air is fully mixed with the raw materials for a period of time. After the fermentation is completed, open the electric valve 6 at the bottom of the discharge barrel 4 to discharge the fermented materials; Step 5: After the material is discharged, when the inner wall of the tank body 1 needs to be cleaned, the upper guide cover 11 and the lower guide cover 12 are brought close to each other by controlling the lifting mechanism and the electric drive rotation mechanism, so that the upper sliding plate 14 and the lower sliding plate 15 are brought close to each other and squeezed against each other, and then the upper sliding plate 14 overcomes the elastic force of the elastic member and slides outward and upward, and the lower sliding plate 15 overcomes the elastic force of the elastic member and slides outward and downward, so that the No. 1 scraper 17 can fit with the inner wall of the tank body 1, and the No. 3 scraper 19 can fit with the inner wall of the tank body 1. The upper and lower air guide covers 11 and 12 are fitted together, and then the inner wall of the tank body 1 can be cleaned by moving up and down and rotating the upper and lower air guide covers 11 and 12 together. When moved to the lower part of the tank body 1, the scraper strips 19 and 20 can be used to clean the bottom of the inner wall of the tank body 1. When moved to the upper part of the tank body 1, the scraper strips 17 and 18 can be used to clean the top of the inner wall of the tank body 1. During the cleaning process, the cleaning liquid is introduced into the tank body 1 through the feed barrel 2, and then discharged through the discharge barrel 4, thereby discharging the dirt generated by the cleaning.
