After the device is used, by rotating the storage barrel to pass through the water in the outer shell, the storage barrel is continuously flushed, so that the residual raw materials attached to the inner wall of the storage barrel are deposited at the bottom of the storage barrel, facilitating the cleaning of the device.

[0022] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention and are not used to limit the present invention.

[0023] Embodiment 1: Referring jointly to Figure 1 - Figure 5As shown, according to an embodiment of the present invention, a cultivating device for edible mushroom strains is provided, including: a housing 1, on one side of which there is an air circulation heating mechanism 2 for heating the gas inside the housing 1, and at the bottom of which there is a position adjustment mechanism 3 for adjusting the height of the water surface at the bottom inside the housing 1; A storage barrel 4, which is rotatably installed inside the housing 1, and the opening end of which is located outside the housing 1. A driving mechanism 5 is provided on the outer peripheral side of the opening end of the storage barrel 4 for driving the storage barrel 4 to rotate; A circular tube 6, which is rotatably installed at the axial center position inside the storage barrel 4, and one end of which close to the air circulation heating mechanism 2 extends outside the housing 1 and is rotatably connected to the housing 1. A number of shunt tubes 7 are oppositely provided on the outer peripheral side of the circular tube 6. The inside of the shunt tube 7 is connected to the inside of the circular tube 6 through a set of telescopic diversion mechanisms 8, and two adjacent sets of telescopic diversion mechanisms 8 are arranged in a staggered manner; A limiting mechanism 9, which is provided inside the wall of the housing 1 for restricting and positioning between the circular tube 6 and the storage barrel 4.

[0024] In this embodiment, when manufacturing the culture medium raw materials, please refer to Figure 1 and Figure 3 As shown, first inject a corresponding amount of water into the housing 1 (an electric control valve is fixedly installed through the outer wall of the housing 1, which is connected to an external water source through a pipeline for injecting water into the housing 1 or discharging the water inside the housing 1 from the electric control valve), and put the raw materials into the storage barrel 4 (the raw materials are mainly composed of waste from edible mushrooms after harvesting, moringa, aloe vera, potato residue, soybean meal, corn kernels, corncobs, wheat bran, bagasse, gypsum powder, quicklime, etc.), so as to complete the preparation work before using the device; Subsequently, start the device. Please refer to Figure 2 and Figure 3 As shown, (a control host is installed on the outer wall of the housing 1 to control different programs inside the general device to run in different ways to cope with the processing of different amounts or different culture media), after the device is started, first the driving mechanism 5 drives the storage barrel 4 to rotate rapidly inside the housing 1 (the driving mechanism 5 is mainly composed of the housing 1, a motor gear ring and a gear transmission mechanism), please refer to Figure 3 and Figure 4 As shown, due to the mutual contact between the shunt tube 7 and the inner wall of the storage barrel 4, a great friction force is generated between the circular tube 6 and the inner wall of the storage barrel 4, so that the storage barrel 4 drives the circular tube 6, the shunt tube 7 and the telescopic diversion mechanism 8 to rotate synchronously with the storage barrel 4 during the rotation process; Please refer to Figure 3 and Figure 4As shown, during the rotation of the storage barrel 4, the dispersed raw materials in the raw materials are caused to conflict with the inner wall of the storage barrel 4 and conflict with each other due to the centrifugal force, and the dispersed raw materials adhere to the inner wall of the storage barrel 4 and rotate together with the storage barrel 4, while the agglomerated raw materials in the raw materials are always located at the bottom of the storage barrel 4 and roll due to their own gravity, and then when the diverter pipe 7 and the telescopic guide mechanism 8 move to the bottom end of the storage barrel 4, they collide with the agglomerated raw materials and break up the agglomerated raw materials to avoid the agglomeration of raw materials affecting the mixing effect of the raw materials; After the raw materials are dispersed, the driving mechanism 5 slows down the rotation speed of the storage barrel 4, so that the storage barrel 4 rotates at a relatively slow speed in the housing 1. At this time, the dispersed raw materials are continuously turned over at the bottom of the storage barrel 4, and when the diverter tube 7 moves to the bottom end of the storage barrel 4, the raw materials inside the raw materials can be pushed out due to the mutual interference between the telescopic guide mechanism 8 and the diverter tube 7 and the raw materials, so that various raw materials are evenly mixed, and there is no dead angle in the mixing and stirring of the raw materials, so that the mixing of the raw materials is relatively uniform; After the raw materials are mixed, please refer to Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, the gas circulation heating mechanism 2 is started, and the gas in the housing 1 is continuously extracted (the housing 1 is made of a heat-insulating material, such as), and the gas is re-injected into the circular tube 6 after being heated, and then the hot steam passes through the telescopic guide mechanism 8 and flows into the shunt pipe 7, and is discharged from various positions of the opening of the shunt pipe 7 and blows on the inner wall of the storage barrel 4; Please refer to Figure 4 , Figure 5 and Figure 7 As shown, after the gas flows into the telescopic flow guiding mechanism 8, the telescopic flow guiding mechanism 8 pneumatically pulls the shunt tube 7 toward the circular tube 6, so that the shunt tube 7 is separated from the inner wall of the storage barrel 4, and a corresponding length of spacing is generated between the shunt tube 7 and the inner wall of the storage barrel 4. At this time, due to the constraint and limitation of the circular tube 6 by the limiting mechanism 9, the circular tube 6 will no longer rotate with the storage barrel 4. Please refer to Figure 1 , Figure 3 , Figure 4 and Figure 5 When the gas circulation heating mechanism 2 is started, the driving mechanism 5 increases the rotation speed of the storage barrel 4 again, so that the storage barrel 4 rotates rapidly in the housing 1. When the raw materials follow the storage barrel 4 to move to the position of the diverter pipe 7, the diverter pipe 7 can scrape off the excess raw materials on the inner wall of the storage barrel 4, so that the raw materials are laid on the inner wall of the storage barrel 4 more evenly. Please refer to Figure 3As shown, after the raw materials are laid on the inner wall of the storage cylinder 4, the air circulation heating mechanism 2 drives the position adjustment mechanism 3 to start, causing the water level in the outer shell 1 to rise until the water in the outer shell 1 soaks the raw materials at the bottom end inside the storage cylinder 4. Thus, during the rotation of the storage cylinder 4, the addition of water to the raw materials is gradually completed; According to the above, during the process of the soaked raw materials rotating with the storage cylinder 4, the heated gas continuously blows on the spread raw materials, and after passing through the gaps between the raw materials and the holes of the storage cylinder 4, it flows back into the outer shell 1, thereby continuously heating the raw materials to gradually increase the temperature of the raw materials until the temperature of the raw materials is equal to the temperature of the heated gas. Thus, the disinfection treatment of the raw materials is completed by high-temperature steam, and the continuous replenishment of water in the raw materials can be synchronized to avoid the excessive loss of water content in the raw materials, resulting in damage to the nutrients in the raw materials due to high temperature. At the same time, when the heated air is used to heat-treat the raw materials, due to the spread of the raw materials on the inner wall of the storage cylinder 4, the heated air can fully heat-treat the raw materials, and there is sufficient water in the raw materials to vaporize into water vapor and emerge from the raw materials, so that the raw materials can be fully disinfected, and there will be almost no residual very small amount of miscellaneous bacteria in the raw materials, which will affect the quality of the culture medium raw materials; After the heating and disinfection of the raw materials are completed, the position adjustment mechanism 3 restores the water level in the outer shell 1 to separate the water from the raw materials. At the same time, the air circulation heating mechanism 2 stops heating the gas and only circulates the gas. At this time, as the gas circulates inside and outside the outer shell 1, the heat quickly dissipates to the outside world, so that the temperature inside the outer shell 1 drops rapidly, and the gas blows on the raw materials during the flow. The small water droplets and water vapor entrained in the gas come into contact with the raw materials and are absorbed by the raw materials to continuously supplement the water lost by the raw materials due to their own temperature. Thus, while maintaining the water content in the raw materials, the raw materials are quickly cooled. The processing of the culture medium raw materials is completed, and then the culture medium raw materials in the storage cylinder 4 are taken out to make the culture medium; According to the above, the stirring and mixing, high-temperature disinfection, cooling, and water addition of the culture medium raw materials can all be automatically completed in one device, and the automation degree of the device is high, greatly improving the processing efficiency of the culture medium raw materials; When cleaning the inner cylinder of the device, according to the above, the water in the outer shell 1 is made to overflow part of the storage cylinder 4, and then the driving mechanism 5 drives the storage cylinder 4 to slowly rotate inside the outer shell 1. Thus, through the flushing of the water on the storage cylinder 4, the attached raw materials on the inner wall of the storage cylinder 4 are washed down and deposited at the bottom inside the storage cylinder 4 when the storage cylinder 4 stops rotating. And by adjusting the height of the water in the outer shell 1, almost all the sewage in the outer shell 1 can be discharged from the electric control valve, facilitating the cleaning of the device; When cleaning the raw materials attached to the inner wall of the storage barrel 4, the contact force between the shunt pipe 7 and the inner wall of the storage barrel 4 is adjusted through the telescopic diversion mechanism 8, so that when the storage barrel 4 rotates, the shunt pipe 7 slides along the inner wall of the storage barrel 4, simulating the scraping operation of a scraper, thereby enhancing the cleaning effect of the storage barrel 4.

[0025] In a further preferred embodiment of the present invention, as Figure 3 and Figure 4 shown, the storage barrel 4 includes a network pipe 41, two circular plates 42 and a cover 43. The two circular plates 42 are relatively fixedly installed at both ends of the network pipe 41, and the cover 43 is fixedly penetrated through the corresponding circular plate 42 by bolts; In this embodiment, please refer to Figure 3 and Figure 4 shown, the storage barrel 4 composed of the network pipe 41 in the middle enables the water in the outer shell 1 to flow into the storage barrel 4 to wet the raw materials (the holes on the network pipe 41 connect the raw materials in the storage barrel 4). The circular plates 42 at both ends of the storage barrel 4 provide an installation position for the circular pipe 6 and can intercept the water in the storage barrel 4 in the outer shell 1 to prevent the water in the outer shell 1 from flowing out of the storage barrel 4.

[0026] In a further preferred embodiment of the present invention, as Figure 4 and Figure 5 shown, the cross-sectional shape of the shunt pipe 7 is rhombic, and the side of the shunt pipe 7 close to the inner wall of the network pipe 41 is in contact with the inner wall of the network pipe 41; In this embodiment, please refer to Figure 5 and Figure 6 shown, the rhombic setting of the shunt pipe 7 can make the opening of the shunt pipe 7 form a flared opening. Thus, after the gas flows into the shunt pipe 7, due to the limited amount of gas discharged at the exhaust hole 841 of the shunt pipe 7, the gas injected into the shunt pipe 7 first diffuses in the shunt pipe 7 and finally is discharged from various positions at the opening of the shunt pipe 7, forming a linear air flow blowing on the inner wall of the storage barrel 4 to avoid dead corners in the blowing of the air flow on the raw materials, which affects the disinfection and cooling treatment of the raw materials; Moreover, the rhombic setting of the shunt pipe 7 can make the edges formed outside the shunt pipe 7 collide with the raw materials, so that the shunt pipe 7 can more easily break the raw materials when colliding with the raw materials.

[0027] In a further preferred embodiment of the present invention, as Figure 1 、 Figure 3 and Figure 4 shown, the air circulation heating mechanism 2 includes an air pump 21, which is fixedly installed on the outer wall of one side of the outer shell 1. The exhaust end of the air pump 21 is connected and installed with an electric control four-way valve 22. One exhaust port of the electric control four-way valve 22 is inserted into the circular pipe 6 and rotatably connected to the circular pipe 6. The intake end of the air pump 21 is connected and installed with a gas heater 23; The housing 1 of the gas heater 23 is fixedly connected to the housing 1, and the inside of the top interface of the gas heater 23 is connected to the inside of the housing 1 through a connecting pipe; In this embodiment, please refer to Figure 1 , Figure 3 and Figure 4 As shown, when the gas in the housing 1 circulates internally, the air pump 21 starts to continuously extract the gas in the housing 1 through the gas heater 23 and the connecting pipe (the air pump 21 can be a water-ring vacuum pump, and the connecting pipe is a heat-conducting pipe, i.e., a copper pipe or a stainless steel pipe, etc. A heat exchange device or a cooling device can also be provided outside the connecting pipe to enhance the heat dissipation effect of the connecting pipe), and injects it into the circular tube 6 through the electric control four-way valve 22. During this process, the gas heater 23 starts to heat the gas. Closing the gas heater 23 can continuously complete the cooling process of the gas through the circulation of the gas inside and outside the housing 1 (the gas heater 23 is composed of a heat-insulating shell and a gas heating pipe, etc.).

[0028] In a further preferred embodiment of the present invention, as Figure 1 and Figure 3 shown, the position adjustment mechanism 3 includes a piston plate 31, which is arranged below the storage barrel 4, and the outer peripheral wall of which is in contact with the inner wall of the housing 1; Another exhaust hole 841 of the electric control four-way valve 22 is connected with a conduit 32, and the bottom end of the conduit 32 is fixedly inserted into the housing 1 and is located below the piston plate 31; In this embodiment, please refer to Figure 1 and Figure 3 shown, when adjusting the water level in the housing 1, the electric control four-way valve 22 is opened, so that the air pump 21 is connected to the conduit 32. At this time, the gas extracted by the air pump 21 is injected below the piston plate 31 through the electric control four-way valve 22 and the conduit 32, so that a high-pressure chamber is formed below the piston plate 31, pushing the piston plate 31 upward to lift the water in the housing 1, so that the bottom of the storage barrel 4 is inserted into the water; When restoring the water level in the housing 1, the electric control four-way valve 22 is activated, so that the inside of the circular tube 6 is connected to the inside of the conduit 32. At this time, due to the pushing of the piston plate 31 by the weight of the water itself, the piston plate 31 automatically moves downward until the piston plate 31 abuts against the inner wall of the housing 1, and the automation degree of the device is high.

[0029] In a further preferred embodiment of the present invention, as Figure 4 , Figure 5 and Figure 6 shown, the telescopic diversion mechanism 8 includes a piston cylinder 81, which is fixedly installed on the outer peripheral wall of the circular tube 6. A piston rod 82 is slidably installed in the piston cylinder 81, and the end of the piston rod 82 far from the circular tube 6 is fixedly inserted into the corresponding shunt tube 7; The diversion hole 83 is L-shaped and formed in the corresponding piston rod 82. The interior of the diversion hole 83 communicates with the interior of the corresponding piston cylinder 81 and the interior of the corresponding shunt pipe 7. The interior of the diversion hole 83 is connected to the interior of the circular pipe 6 through a connecting member 84; In this embodiment, please refer to Figure 4 , Figure 5 and Figure 6 As shown in the figure, the gas in the circular pipe 6 flows into the diversion hole 83 through the connecting member 84. Then, a small portion of the gas in the diversion hole 83 flows into the piston rod 82 to push the piston rod 82 into the piston cylinder 81, while the other portion of the gas directly flows into the shunt pipe 7. Thus, when heating the raw materials, the distance between the shunt pipe 7 and the inner wall of the storage cylinder 4 can be automatically adjusted without the need to provide an additional driving structure, reducing the manufacturing cost of the device.

[0030] In a further preferred embodiment of the present invention, as Figure 5 and Figure 6 shown, a first spring 85 is provided in the piston cylinder 81, and both ends of the first spring 85 are fixedly connected to the corresponding piston rod 82 and the inner wall of the corresponding piston cylinder 81; A pressure limiting valve 89 is fixedly installed in the opening at the end of the diversion hole 83 away from the circular pipe 6; In this embodiment, please refer to Figure 6 shown. After the device is used up, the electro-controlled four-way valve 22 is activated to make the circular pipe 6 communicate with the outside (the last external port of the electro-controlled four-way valve 22 communicates with the outside). At this time, due to the pushing of the first spring 85 on the piston rod 82, the piston rod 82 retracted into the piston cylinder 81 automatically extends out of the piston cylinder 81 until the shunt pipe 7 abuts against the inner wall of the storage cylinder 4. And due to the pushing of the first spring 85 on the piston rod 82, there is a corresponding intensity of the abutting force between the shunt pipe 7 and the inner wall of the storage cylinder 4, so that a corresponding intensity of frictional force is generated between the shunt pipe 7 and the inner wall of the storage cylinder 4, enabling the piston cylinder 81 to drive the circular pipe 6 to rotate together when rotating; When the air flow is injected into the diversion hole 83, due to the blocking of the pressure limiting valve 89, the gas injected into the diversion hole 83 first flows into the piston cylinder 81. After the pressure in the piston cylinder 81 reaches the threshold value, a sufficient pressure difference is generated at both ends of the pressure limiting valve 89. At this time, the gas in the diversion hole 83 will flow into the shunt pipe 7, enabling the piston rod 82 to stably retract into the piston cylinder 81 during the process of injecting the gas into the shunt pipe 7.

[0031] In a further preferred embodiment of the present invention, as Figure 5 and Figure 6 shown, the connecting member 84 includes a plurality of exhaust holes 841, which are formed on the outer wall of the circular pipe 6; The outer tube 842 is disposed within the corresponding piston cylinder 81, and one end thereof is inserted into the corresponding exhaust hole 841. A sliding inner tube 843 is installed within the opening at the other end of the outer tube 842, and the end of the inner tube 843 remote from the circular tube 6 is inserted into the corresponding diversion hole 83 and fixedly connected to the corresponding piston rod 82; In this embodiment, please refer to Figure 5 and Figure 6 As shown, during the reciprocating sliding of the piston rod 82 within the piston cylinder 81, the inner tube 843 synchronously slides within the outer tube 842, thereby adjusting the overall length of the connecting member 84 without affecting the communication state between the diversion hole 83 and the interior of the circular tube 6.

[0032] In a further preferred embodiment of the present invention, as Figure 3 , Figure 4 and Figure 7 As shown, the limiting mechanism 9 includes a plurality of limiting grooves 91 formed on the outer wall of the circular tube 6; A plurality of sliding grooves 92 are formed in the shell wall of the housing 1 at positions corresponding to the limiting grooves 91. A push rod 93 is slidably installed therein. A second spring 94 is disposed within the sliding groove 92, and both ends of the second spring 94 are fixedly connected to the inner wall of the corresponding sliding groove 92 and one end of the corresponding push rod 93, respectively; The other end of the push rod 93 is rotatably installed with a ball 95, and the end of the ball 95 close to the circular tube 6 is inserted into the corresponding limiting groove 91 and contacts the inner wall of the corresponding limiting groove 91; In this embodiment, please refer to Figure 7 As shown, when the circular tube 6 rotates together with the storage cylinder 4, due to the mutual contact between the inner wall of the limiting groove 91 and the ball 95, the ball 95 can be automatically extruded from the limiting groove 91 along the outer arc wall of the ball 95 to automatically release the constrained limiting state between the circular tube 6 and the housing 1. And after the diversion tube 7 is separated from the storage cylinder 4, since the circular tube 6 loses the push of the storage cylinder 4, at this time, due to the mutual contact between the ball 95 and the inner wall of the limiting groove 91, a binding force can be applied between the circular tube 6 and the housing 1, so that the circular tube 6 will not rotate together with the storage cylinder 4. At this time, the gas discharged from the opening of the diversion groove can successively complete the blowing of the raw materials on the inner wall of the storage cylinder 4, or the diversion groove can complete the scraping of the excess raw materials on the inner wall of the storage cylinder 4.

[0033] Working principle: When manufacturing the culture medium raw materials, first unscrew the bolt from the circular plate 42 and pull out the cover 43 from the storage cylinder 4. Then, the corresponding amount of raw materials can be filled into the storage cylinder 4 through the installation hole of the cover 43. After the raw materials are filled, the operator re-inserts the cover 43 into the installation hole of the storage cylinder 4 and fixes the cover 43 to the circular plate 42 through the bolt, and the feeding operation of the raw materials in the storage cylinder 4 is completed; After the raw material feeding operation is completed, the operator opens the electric control valve through the control host, and the external water source flows into the housing 1 through the pipeline and the electric control valve. After the opening time of the electric control valve is reached, the electric control valve is closed. At this time, a corresponding amount of water is stored in the housing 1, and the water feeding operation in the housing 1 is completed; After the preparation work before the use of the device is completed, the control host control device is started, and the motor drives the storage barrel 4 in the housing 1 to rotate rapidly through the gear transmission mechanism and the gear ring. At this time, due to the push of the spring 1 85 on the piston rod 82, a corresponding resistance force is generated between the shunt tube 7 and the inner wall of the storage barrel 4, thereby generating a corresponding friction force between the shunt tube 7 and the inner wall of the storage barrel 4. At this time, the rotating storage barrel 4 drives the shunt tube 7, the piston rod 82, the piston barrel 81 and the round tube 6 to rotate synchronously; During the rotation of the storage barrel 4, the dispersed raw materials in the raw materials are subjected to a corresponding degree of friction because of the centrifugal force and their own light weight, which makes the raw materials and the inner wall of the storage barrel 4 conflict with each other and the raw materials conflict with each other. At this time, the dispersed raw materials adhere to the inner wall of the storage barrel 4 and rotate together with the raw materials, while the agglomerated raw materials in the raw materials are always located at the bottom of the storage barrel 4 and roll due to their own large gravity. When the shunt tube 7 and the piston rod 82 move to the bottom end of the storage barrel 4, the edges of the shunt tube 7 and the outer arc wall of the piston rod 82 collide with the agglomerated raw materials, thereby breaking up the agglomerated raw materials. After the raw materials are dispersed, the driving mechanism 5 slows down the rotation speed of the storage barrel 4, so that the storage barrel 4 rotates at a relatively slow speed in the housing 1. At this time, the dispersed raw materials at the bottom of the storage barrel 4 continue to turn over, and when the diverter tube 7 moves to the bottom end of the storage barrel 4, the piston rod 82 and the diverter tube 7 are in conflict with the raw materials, so that the raw materials inside the raw materials can be pushed out, and finally various raw materials are evenly mixed; After the raw materials are mixed, the air pump 21 starts to continuously extract the gas in the shell 1 through the gas heater 23 and the connecting pipe, and injects it into the circular tube 6 through the electrically controlled four-way valve 22. In this process, the gas heater 23 starts to complete the heating treatment of the gas, and the gas injected into the circular tube 6 flows into the piston cylinder 81 through the exhaust hole 841, the outer tube 842, the inner tube 843 and the guide hole 83, so that a high-pressure chamber is formed in the piston cylinder 81 at the outer peripheral side of the piston rod 82, thereby applying a thrust toward the piston cylinder 81 to the piston rod 82, so that the piston rod 82 gradually retracts into the piston cylinder 81 and compresses the spring 1 85. When the pressure in the piston cylinder 81 reaches the threshold, the pressure limiting valve 8 9, the pressure difference at both ends also reaches the threshold value simultaneously. At this time, the gas that subsequently flows into the guide hole 83 passes through the pressure limiting valve 89 and flows into the shunt pipe 7. The piston rod 82 will not continue to retract into the piston cylinder 81, and at this time, there is a corresponding length of spacing between the shunt pipe 7 and the inner wall of the piston cylinder 81. At the same time, due to the push of the spring 2 94 on the push rod 93, the ball 95 and the inner wall of the limiting groove 91 conflict with each other, and the round tube 6 and the shunt pipe 7 will not rotate together with the storage barrel 4. At this time, as the storage barrel 4 rotates, the shunt pipe 7 conflicts with the raw material, and the shunt pipe 7 forms a structure similar to a scraper, which scrapes off the excess raw material on the inner wall of the storage barrel 4, so that the raw material of the corresponding thickness is laid more evenly on the inner wall of the storage barrel 4. After the gas flows into the shunt pipe 7, since the amount of gas discharged from the exhaust hole 841 of the shunt pipe 7 is limited, the gas injected into the shunt pipe 7 is first diffused in the shunt pipe 7, and finally discharged from various positions of the opening of the shunt pipe 7, forming a linear airflow blowing on the raw material. At this time, due to the loss of gas in the shell 1, a pressure difference is formed inside and outside the mesh tube 41. The gas blowing on the raw material passes through the gaps between the raw materials and the holes of the mesh tube 41 and flows into the shell 1 to supplement the gas lost in the shell 1. When the gas passes through the gaps between the raw materials, the raw materials can be fully heated. After the distance between the shunt pipe 7 and the inner wall of the storage barrel 4 reaches the threshold value, the electrically controlled four-way valve 22 is started, so that the air pump 21 is connected with the conduit 32. At this time, the gas extracted by the air pump 21 is injected into the bottom of the piston plate 31 through the electrically controlled four-way valve 22 and the conduit 32, so that a high-pressure chamber is formed under the piston plate 31, and the piston plate 31 is pushed upward to lift the water in the shell 1 until the water in the shell 1 passes through the holes of the mesh tube 41 and soaks the raw materials at the bottom of the storage barrel 4. As the storage barrel 4 rotates, the raw materials in the storage barrel 4 are continuously soaked to replenish the water in the raw materials when the raw materials are heated, so that when the gas heats the raw materials, more water vapor is generated inside the raw materials, and the raw materials are further fully heated. After the raw material heating and disinfection are completed, the electronic control four-way valve 22 is activated, so that the inside of the circular tube 6 is communicated with the inside of the conduit 32. At this time, due to the pushing of the piston plate 31 by the weight of the water itself, the piston plate 31 automatically moves downward until the piston plate 31 abuts against the inner wall of the outer shell 1. The water level in the outer shell 1 drops and separates from the storage barrel 4. At the same time, the gas heater 23 stops heating the gas. At this time, during the process of the gas passing through the connecting pipe, the gas continuously exchanges heat with the outside air through the connecting pipe, so that the temperature of the circulating gas gradually decreases, and quickly takes away the heat on the raw material during the process of passing through the gaps between the raw materials, so as to reduce the temperature of the raw material. At the same time, when the gas blows on the raw material, the small water droplets and water vapor entrained in the gas come into contact with the raw material and are absorbed by the raw material, so as to continuously supplement the water lost by the raw material due to its own temperature; It should be noted that when the raw material needs to contain more water, or when the condensed water droplets in the gas cannot timely supplement the water in the raw material, the water in the raw material can also be supplemented by the above-mentioned soaking method, and the excess water in the raw material can be thrown out by rotating the raw material; It should be noted that a water level sensor can also be installed in the outer shell 1 to monitor the water content in the outer shell 1, so as to timely supplement the water in the outer shell 1 by opening and closing the electronic control valve, so that a corresponding amount of water is always stored in the outer shell 1; After the mixing and disinfection treatment of the raw material is completed, the air pump 21 stops running, and the driver gradually slows down the rotation speed of the storage barrel 4. At this time, as the rotation speed of the storage barrel 4 decreases, the raw material slides down from the inner wall of the storage barrel 4 and deposits at the bottom of the storage barrel 4. At this time, according to the above, the cover 43 is disassembled, and the raw material can be taken out of the storage barrel 4; It should be noted that a scraper can be used to take out the raw material from the storage barrel 4, or telescopic support legs can be provided at the bottom of the device. By adjusting the support legs, the storage barrel 4 can be tilted, so that the raw material slides out of the storage barrel 4 or other methods; After the device is used up and when cleaning the device, according to the above, part of the water in the outer shell 1 is stored in the storage barrel 4, and then the driving mechanism 5 drives the storage barrel 4 to slowly rotate in the outer shell 1, so that the raw material attached to the inner wall of the storage barrel 4 is washed down by the water and deposits at the bottom of the storage barrel 4 when the storage barrel 4 stops rotating. And by adjusting the height of the water in the outer shell 1, almost all the sewage in the outer shell 1 can be discharged from the electronic control valve; When cleaning the raw material attached to the inner wall of the storage barrel 4, by adjusting the amount of gas in the piston cylinder 81, the contact force between the shunt pipe 7 and the inner wall of the storage barrel 4 can be adjusted, so that the shunt pipe 7 slides along the inner wall of the storage barrel 4 when the storage barrel 4 rotates, so as to simulate the scraping operation of the scraper to scrape off the raw material on the inner wall of the storage barrel 4 that cannot be washed down by water.

Subsequently, the high-temperature disinfection treatment of the raw materials is completed by the high-temperature gas discharged from the air circulation heating mechanism 22 and the water in the outer shell 11; S5: By gradually reducing the temperature of the blowing gas on the raw materials by the air circulation heating mechanism 22, the rapid cooling treatment of the raw materials is completed; S6: Stop the operation of the device, and through the disassembly and assembly of the cover 4343 and the corresponding circular plate 4242, the processed raw materials are taken out from the storage cylinder 44; In this embodiment, the processing flow of the culture medium raw materials in the improved method for cultivating edible mushroom strains is convenient to operate, does not require the replacement of multiple devices, and has a high processing efficiency.
