Description

Technical Field

[0001] This invention relates to the technical field of edible fungi spawn cultivation devices, specifically to an edible fungi spawn cultivation device and cultivation method. Background Technology

[0002] Edible fungi refer to large, edible mushrooms. Specifically, edible fungi are mushrooms that can be eaten. Mushrooms are large fungi that can form large, fleshy fruiting bodies or sclerotia that can be eaten or used medicinally. They are commonly known as mushrooms. In the process of edible fungi cultivation, the cultivation of edible fungi strains is an important step to ensure the quality of the cultivated edible fungi.

[0003] In the cultivation of edible fungi spores, the preparation of the culture medium is a crucial process, providing sufficient nutrients for the cultivation of edible fungi spores. When preparing the raw materials for the culture medium, it is generally necessary to complete the uniform mixing of the raw materials, followed by sterilization through high-temperature steam. Firstly, the mixing of the raw materials and the high-temperature steam sterilization both need to be completed by different equipment, which reduces the processing efficiency of the culture medium raw materials. Moreover, the stacking and sterilization of the raw materials may result in incomplete sterilization of the internal raw materials, which may contain a very small amount of contaminating bacteria, affecting the quality of the culture medium raw materials. Summary of the Invention

[0004] Therefore, the technical problem to be solved by the present invention is to provide an edible fungi strain cultivation device and cultivation method, which can complete the thorough mixing and high-temperature steam sterilization of the culture medium raw materials in one operation, and can thoroughly sterilize the raw materials to avoid the presence of a very small number of residual bacteria in the raw materials affecting the quality of the culture medium raw materials.

[0015] Preferably, the telescopic flow guiding mechanism includes a piston cylinder, which is fixedly mounted on the outer peripheral wall of the circular tube, and a piston rod is slidably mounted inside the piston cylinder, with one end of the piston rod away from the circular tube fixedly inserted into the corresponding diversion pipe;

[0016] The guide hole is L-shaped and opened inside the corresponding piston rod, and its interior is connected to the interior of the corresponding piston cylinder and the interior of the corresponding flow divider. The interior of the guide hole is connected to the interior of the circular tube through a connector.

[0017] Preferably, a spring is provided inside the piston cylinder, and the two ends of the spring are fixedly connected to the corresponding piston rod and the inner wall of the corresponding piston cylinder, respectively.

[0024] A method for cultivating edible fungi strains, comprising the aforementioned edible fungi strain cultivation apparatus:

[0025] S1: The filling of raw materials into the storage cylinder is completed by disassembling and assembling the cover and the corresponding circular plate;

[0026] S2: The rotation of the storage cylinder causes the diversion pipe and piston rod to collide with the agglomerated raw material, breaking up the agglomerated raw material;

[0027] S3: The raw materials are mixed by rotating and turning the storage cylinder;

[0028] S4: By rotating the storage cylinder in conjunction with the scraping operation of the distribution pipe on the raw material, the raw material is laid on the inner wall of the storage cylinder. Then, the high-temperature gas discharged by the air circulation heating mechanism and the water in the outer shell complete the high-temperature disinfection treatment of the raw material.

[0029] S5: The temperature of the blowing gas on the raw material is gradually reduced by the air circulation heating mechanism, thereby completing the rapid cooling process of the raw material.

[0030] S6: Stop the operation of the device, and remove the processed raw material from the storage cylinder by disassembling and assembling the cover and the corresponding circular plate. Beneficial effects

[0031] 1. When manufacturing culture medium raw materials, the process can be carried out in the improved edible fungus spawn cultivation device, which can complete the mixing, high-temperature sterilization, cooling and water addition of the culture medium raw materials in one go. The device has a high degree of automation, which greatly improves the processing efficiency of culture medium raw materials.

[0032] 2. When mixing the culture medium raw materials, the clumps of the culture medium raw materials can be broken up at the same time to avoid the clumps affecting the mixing effect. The mixing of the raw materials is carried out by the rotating storage cylinder, and there are almost no dead corners in the mixing process, resulting in a more uniform mixing of the raw materials.

[0033] 3. During the high-temperature sterilization of culture medium raw materials, the raw materials can be spread on the surface, and due to the pressure difference inside and outside the storage cylinder, the heated air can pass through the gaps between the raw materials and the holes in the storage cylinder, and come into full contact with the raw materials, so that the raw materials can be fully sterilized. There will be almost no residual microorganisms in the raw materials, which will affect the quality of the culture medium raw materials.

[0034] 4. During the raw material disinfection process, the rotating storage cylinder causes the raw material to intermittently pass through the water inside the shell, ensuring that the raw material always maintains sufficient moisture when the heated air is used for heating treatment, so as to avoid the raw material having too little moisture content and the nutrients in the raw material being damaged by high temperature.

[0035] 5. When cooling culture medium raw materials through gas, the condensation water in the gas can continuously replenish the water lost from the raw materials due to their own temperature, thereby maintaining the water content in the raw materials while rapidly cooling them, further improving the processing efficiency of culture medium raw materials.

[0036] 6. After the device is used, the storage cylinder is rotated and moves through the water inside the outer shell to continuously flush the storage cylinder, so that the residual raw materials attached to the inner wall of the storage cylinder are deposited at the bottom of the storage cylinder, which facilitates the cleaning of the device.

[0050] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0051] Example 1: (Refer to the previous example) Figure 1 - Figure 5 As shown, according to an embodiment of the present invention, an edible fungus spawn cultivation device is provided, comprising: an outer shell 1, wherein a gas circulation heating mechanism 2 is provided on one side for heating the gas inside the outer shell 1, and an adjustment mechanism 3 is provided at the bottom for adjusting the height of the water level at the bottom inside the outer shell 1.

[0052] The storage cylinder 4 is rotatably mounted inside the outer shell 1, and its open end is located outside the outer shell 1. A drive mechanism 5 is provided on the outer periphery of the open end of the storage cylinder 4 for driving the storage cylinder 4 to rotate.

[0053] The circular tube 6 is rotatably mounted at the axial position inside the storage cylinder 4, and one end of it near the air circulation heating mechanism 2 extends to the outside of the outer shell 1 and is rotatably connected to the outer shell 1. Several diversion tubes 7 are provided on the outer periphery of the circular tube 6. The interior of the diversion tube 7 is connected to the interior of the circular tube 6 through a set of telescopic guide mechanisms 8, and adjacent sets of telescopic guide mechanisms 8 are staggered.

[0054] The limiting mechanism 9 is located inside the shell wall of the outer shell 1 and is used to constrain and limit the relationship between the circular tube 6 and the storage cylinder 4.

[0055] In this embodiment, when manufacturing the culture medium raw materials, please refer to... Figure 1 and Figure 3 As shown, first, inject the corresponding amount of water into the outer shell 1 (an electrically controlled valve is fixedly installed through the outer wall of the outer shell 1, which is connected to an external water source through a pipe for injecting water into the outer shell 1 or for the water in the outer shell 1 to be discharged from the electrically controlled valve), and put the raw materials into the storage cylinder 4 (the raw materials are mainly composed of waste from the harvest of edible fungi, moringa, aloe vera, potato residue, soybean meal, corn kernels, corn cobs, bran, sugarcane bagasse, gypsum powder, quicklime, etc.) to complete the preparation work before the use of the device;

[0056] Then start the device, please refer to... Figure 2 and Figure 3 As shown, (the outer wall of the outer casing 1 is equipped with a control host that controls different internal programs to operate in different ways to handle different quantities or different culture media). After the device is started, the drive mechanism 5 first drives the storage cylinder 4 to rotate rapidly inside the outer casing 1. (The drive mechanism 5 mainly consists of the outer casing 1, a motor gear ring, and a gear transmission mechanism). Please refer to... Figure 3 and Figure 4As shown, due to the mutual contact between the diversion pipe 7 and the inner wall of the storage cylinder 4, a large frictional force is generated between the round pipe 6 and the inner wall of the storage cylinder 4, which causes the storage cylinder 4 to rotate synchronously with the round pipe 6, the diversion pipe 7 and the telescopic guide mechanism 8 during the rotation process.

[0057] Please refer to Figure 3 and Figure 4 As shown, during the rotation of the storage cylinder 4, the dispersed raw materials in the raw materials are subject to centrifugal force, causing the raw materials to come into contact with each other and with the inner wall of the storage cylinder 4. The dispersed raw materials adhere to the inner wall of the storage cylinder 4 and rotate together with the storage cylinder 4. Meanwhile, the agglomerated raw materials are always located at the bottom of the storage cylinder 4 and roll due to their own gravity. Then, when the diversion pipe 7 and the telescopic guide mechanism 8 move to the bottom of the storage cylinder 4, they collide with the agglomerated raw materials and break them up, so as to avoid the agglomerated raw materials from affecting the mixing effect of the raw materials.

[0058] After the raw materials are dispersed, the drive mechanism 5 slows down the rotation speed of the storage cylinder 4, so that the storage cylinder 4 rotates at a slower and uniform speed inside the outer shell 1. At this time, the dispersed raw materials at the bottom of the storage cylinder 4 continue to tumble, and when the diversion pipe 7 moves to the bottom of the storage cylinder 4, the material inside the material can be pushed out due to the mutual contact between the telescopic guide mechanism 8 and the diversion pipe 7 and the raw materials, so that the various raw materials are mixed evenly and there are no dead corners in the mixing and stirring of the raw materials, making the mixing of the raw materials more uniform.

[0059] 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 continuously draws gas from the outer shell 1 (the outer shell 1 is made of heat insulation material, such as), and after heating the gas, it is reinjected into the round tube 6. Then the hot steam passes through the telescopic guide mechanism 8 and flows into the diversion pipe 7, and is discharged from the opening of the diversion pipe 7 at various positions and blown onto the inner wall of the storage cylinder 4.

[0060] Please refer to Figure 4 , Figure 5 and Figure 7 As shown, after the gas flows into the telescopic guide mechanism 8, the telescopic guide mechanism 8 pneumatically pulls the diversion pipe 7 towards the circular tube 6, causing the diversion pipe 7 to separate from the inner wall of the storage cylinder 4, and creating a gap of corresponding length between the diversion pipe 7 and the inner wall of the storage cylinder 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 cylinder 4.

[0061] Please refer to Figure 1 , Figure 3 , Figure 4 and Figure 5At the same time as the air circulation heating mechanism 2 is started, the drive mechanism 5 increases the rotation speed of the storage cylinder 4 again, so that the storage cylinder 4 rotates rapidly inside the outer shell 1. When the raw material moves with the storage cylinder 4 to the position of the diversion pipe 7, the diversion pipe 7 can scrape off the excess raw material on the inner wall of the storage cylinder 4, so that the raw material is spread more evenly on the inner wall of the storage cylinder 4.

[0062] Please refer to Figure 3 As shown, after the raw materials are laid on the inner wall of the storage cylinder 4, the air circulation heating mechanism 2 drives the 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 of the storage cylinder 4, so that water is gradually added to the raw materials during the rotation of the storage cylinder 4.

[0063] As described above, during the rotation of the storage cylinder 4 after soaking, the heated gas continuously blows onto the spread raw material and flows back into the outer shell 1 after passing through the gaps between the raw materials and the holes in the storage cylinder 4, thereby continuously heating the raw material so that the temperature of the raw material gradually rises until the temperature of the raw material is equal to that of the heated gas. This completes the sterilization of the raw material through high-temperature steam, and the moisture in the raw material can be continuously replenished simultaneously to avoid the damage to the nutrients in the raw material due to excessively low moisture content. At the same time, when the heated air is used to heat the raw material, since the raw material is spread on the inner wall of the storage cylinder 4, the heated air can fully heat the raw material, and the sufficient moisture in the raw material vaporizes into water vapor and emerges from the raw material, thereby ensuring that the raw material is fully sterilized. There are almost no trace amounts of bacteria left in the raw material, which would affect the quality of the culture medium raw material.

[0064] After the raw material is heated and sterilized, the adjusting mechanism 3 restores the water level inside the outer shell 1, separating the water from the raw material. At the same time, the gas circulation heating mechanism 2 stops the gas heating process and only circulates the gas. As the gas circulates inside and outside the outer shell 1, the heat is quickly dissipated to the outside, causing the temperature inside the outer shell 1 to drop rapidly. During the gas flow, the gas blows onto the raw material, and the small water droplets and water vapor carried in the gas come into contact with the raw material and are absorbed by the raw material to continuously replenish the moisture lost from the raw material due to its own temperature. Thus, while maintaining the water content in the raw material, the raw material is rapidly cooled. The processing of the culture medium raw material is completed. Then, the culture medium raw material in the storage cylinder 4 is taken out to make the culture medium.

[0065] Based on the above, the mixing, high-temperature sterilization, cooling and water addition of culture medium raw materials can all be completed automatically in one device, and the device has a high degree of automation, which greatly improves the processing efficiency of culture medium raw materials.

[0066] When cleaning the inner cylinder of the device, the water in the outer shell 1 is allowed to overflow part of the storage cylinder 4 as described above. Then, the drive mechanism 5 drives the storage cylinder 4 to rotate slowly inside the outer shell 1. The water washes down the material adhering to the inner wall of the storage cylinder 4 and deposits it at the bottom of the storage cylinder 4 when the storage cylinder 4 stops rotating. By adjusting the water level inside the outer shell 1, almost all the wastewater inside the outer shell 1 can be discharged through the electrically controlled valve, which facilitates the cleaning of the device.

[0067] When cleaning the raw materials adhering to the inner wall of the storage cylinder 4, the contact force between the diversion pipe 7 and the inner wall of the storage cylinder 4 is adjusted by the telescopic guide mechanism 8, so that the diversion pipe 7 slides against the inner wall of the storage cylinder 4 when the storage cylinder 4 rotates, to simulate the scraping operation of the scraper, thereby enhancing the cleaning effect of the storage cylinder 4.

[0068] In a further preferred embodiment of the invention, such as Figure 3 and Figure 4 As shown, the storage cylinder 4 includes a mesh tube 41, two circular plates 42 and a cover 43. The two circular plates 42 are fixedly installed at both ends of the mesh tube 41, and the cover 43 is fixed through the corresponding circular plate 42 by bolts.

[0069] In this embodiment, please refer to Figure 3 and Figure 4 As shown, the storage cylinder 4, which consists of a mesh tube 41 in the middle, allows water from the outer shell 1 to flow into the storage cylinder 4 to wet the raw material (the holes on the mesh tube 41 connect the raw material to the storage cylinder 4). The circular plates 42 at both ends of the storage cylinder 4 provide installation positions for the circular tube 6 and can intercept the water in the storage cylinder 4 into the outer shell 1 to prevent the water in the outer shell 1 from flowing out of the storage cylinder 4.

[0070] In a further preferred embodiment of the invention, such as Figure 4 and Figure 5 As shown, the cross-sectional shape of the diversion pipe 7 is rhomboid, and the side of the diversion pipe 7 closest to the inner wall of the network pipe 41 is connected to the inner wall of the network pipe 41.

[0071] In this embodiment, please refer to Figure 5 and Figure 6 As shown, the diamond-shaped arrangement of the diversion pipe 7 allows the opening of the diversion pipe 7 to form an flared opening. This allows the gas to diffuse within the diversion pipe 7 first, due to the limited amount of gas discharged at the exhaust port 841 of the diversion pipe 7, and finally be discharged from various locations at the opening of the diversion pipe 7, forming a linear airflow that blows onto the inner wall of the storage cylinder 4. This avoids dead zones in the airflow blowing onto the raw materials, which would affect the disinfection and cooling of the raw materials.

[0072] Furthermore, the diamond-shaped arrangement of the diversion pipe 7 allows the outer edge of the diversion pipe 7 to collide with the raw material, making it easier for the diversion pipe 7 to break the raw material when it collides with it.

[0073] In a further preferred embodiment of the invention, such as Figure 1 , Figure 3 and Figure 4 As 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 housing 1. The exhaust end of the air pump 21 is connected to an electrically controlled four-way valve 22. One exhaust port of the electrically controlled four-way valve 22 is inserted into the round pipe 6 and rotatably connected to the round pipe 6. The air inlet end of the air pump 21 is connected to a gas heater 23.

[0074] The outer shell 1 of the gas heater 23 is fixedly connected to the outer shell 1, and the interior of the top interface of the gas heater 23 is connected to the interior of the outer shell 1 through a connecting pipe;

[0075] In this embodiment, please refer to Figure 1 , Figure 3 and Figure 4 As shown, during the internal circulation of gas within the outer casing 1, the gas pump 21 is activated to continuously extract gas from the outer casing 1 through the gas heater 23 and the connecting pipe (the gas 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 installed outside the connecting pipe to enhance the heat dissipation effect of the connecting pipe), and the gas is injected into the circular pipe 6 through the electrically controlled four-way valve 22. During this process, the gas heater 23 is activated to heat the gas. When the gas heater 23 is turned off, the gas cooling process can be continuously completed through the gas circulation inside and outside the outer casing 1 (the gas heater 23 consists of a heat insulation shell and a gas heating pipe, etc.).

[0076] In a further preferred embodiment of the invention, such as Figure 1 and Figure 3 As shown, the adjusting mechanism 3 includes a piston plate 31, which is located below the storage cylinder 4, and its outer peripheral wall is in contact with the inner wall of the outer casing 1.

[0077] Another exhaust port 841 of the electrically controlled four-way valve 22 is connected to a conduit 32, and the bottom end of the conduit 32 is fixedly inserted into the housing 1 and located on the bottom side of the piston plate 31.

[0078] In this embodiment, please refer to Figure 1 and Figure 3As shown, when adjusting the water level inside the outer casing 1, the electrically controlled four-way valve 22 opens, connecting the air pump 21 to the conduit 32. At this time, the gas drawn by the air pump 21 is injected into the area below the piston plate 31 through the electrically controlled four-way valve 22 and the conduit 32, thereby forming a high-pressure chamber below the piston plate 31, pushing the piston plate 31 upward to raise the water inside the outer casing 1, so that the bottom of the storage cylinder 4 is inserted into the water.

[0079] When the water level inside the outer shell 1 is restored, the electrically controlled four-way valve 22 is activated, which connects the inside of the circular pipe 6 with the inside of the conduit 32. At this time, due to the weight of the water itself pushing the piston plate 31, the piston plate 31 automatically moves down until the piston plate 31 and the inner wall of the outer shell 1 come into contact with each other. The device has a high degree of automation.

[0080] In a further preferred embodiment of the invention, such as Figure 4 , Figure 5 and Figure 6 As shown, the telescopic flow guiding mechanism 8 includes a piston cylinder 81, which is fixedly mounted on the outer peripheral wall of the circular tube 6. A piston rod 82 is slidably mounted inside the piston cylinder 81, and the end of the piston rod 82 away from the circular tube 6 is fixedly inserted into the corresponding diversion pipe 7.

[0081] The guide hole 83 is L-shaped and is opened in the corresponding piston rod 82. Its interior is connected to the interior of the corresponding piston cylinder 81 and the interior of the corresponding diverter 7. The interior of the guide hole 83 is connected to the interior of the circular tube 6 through the connector 84.

[0082] In this embodiment, please refer to Figure 4 , Figure 5 and Figure 6 As shown, the gas in the circular tube 6 flows into the guide hole 83 through the connector 84. Then, a small portion of the gas in the guide 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 flows directly into the diversion pipe 7. This allows the distance between the diversion pipe 7 and the inner wall of the storage cylinder 4 to be automatically adjusted when heating the raw material. No additional drive structure is required, which reduces the manufacturing cost of the device.

[0083] In a further preferred embodiment of the invention, such as Figure 5 and Figure 6 As shown, a spring 85 is provided inside the piston cylinder 81, and the two ends of the spring 85 are fixedly connected to the corresponding piston rod 82 and the inner wall of the corresponding piston cylinder 81, respectively.

[0084] A pressure limiting valve 89 is fixedly installed inside the opening at the end of the guide hole 83 away from the circular tube 6;

[0085] In this embodiment, please refer to Figure 6As shown, after the device is used, the electrically controlled four-way valve 22 is activated to connect the circular pipe 6 to the outside (the last external port of the electrically controlled four-way valve 22 is connected to the outside). At this time, due to the push of the spring-85 on the piston rod 82, the piston rod 82, which is retracted into the piston cylinder 81, automatically extends out of the piston cylinder 81 until the diversion pipe 7 and the inner wall of the storage cylinder 4 come into contact with each other. Due to the push of the spring-85 on the piston rod 82, there is a corresponding strength of contact force between the diversion pipe 7 and the inner wall of the storage cylinder 4, so that a corresponding strength of friction force is generated between the diversion pipe 7 and the inner wall of the storage cylinder 4, so that the piston cylinder 81 can drive the circular pipe 6 to rotate together when it rotates.

[0086] When the gas flow is injected into the guide hole 83, due to the obstruction of the pressure relief valve 89, the gas injected into the guide hole 83 will first flow into the piston cylinder 81. After the pressure in the piston cylinder 81 reaches the threshold, the pressure relief valve 89 generates a sufficient pressure difference. Only then will the gas in the guide hole 83 flow into the diversion pipe 7, so that the piston rod 82 can stably retract into the piston cylinder 81 during the process of injecting the gas into the diversion pipe 7.

[0087] In a further preferred embodiment of the invention, such as Figure 5 and Figure 6 As shown, the connector 84 includes a plurality of vent holes 841, which are opened on the outer wall of the circular tube 6;

[0088] An outer tube 842 is disposed inside the corresponding piston cylinder 81, and one end of it is inserted into the corresponding exhaust hole 841. An inner tube 843 is slidably installed in the opening at the other end of the outer tube 842, and the end of the inner tube 843 away from the round tube 6 is inserted into the corresponding guide hole 83 and fixedly connected to the corresponding piston rod 82.

[0089] 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 simultaneously slides within the outer tube 842, thereby adjusting the overall length of the connector 84 without affecting the communication between the guide hole 83 and the inside of the circular tube 6.

[0090] In a further preferred embodiment of the invention, such as Figure 3 , Figure 4 and Figure 7 As shown, the limiting mechanism 9 includes several limiting grooves 91, which are formed on the outer wall of the circular tube 6;

[0091] Several sliding grooves 92 are opened in the shell wall of the outer shell 1 at the position corresponding to the limiting groove 91. A push rod 93 is slidably installed in the groove 92. A spring 94 is provided in the groove 92. The two ends of the spring 94 are fixedly connected to the inner wall of the corresponding groove 92 and one end of the corresponding push rod 93, respectively.

[0092] The other end of the push rod 93 is rotatably equipped with a ball bearing 95, and the end of the ball bearing 95 near the round tube 6 is inserted into the corresponding limiting groove 91 and contacts the inner wall of the corresponding limiting groove 91.

[0093] 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 squeezed out from the limiting groove 91 along the outer arc wall of the ball 95, so as to automatically release the constraint and limiting state between the circular tube 6 and the outer shell 1. After the diversion tube 7 separates 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 constraint force can be applied between the circular tube 6 and the outer shell 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 sequentially complete the blowing of the raw material on the inner wall of the storage cylinder 4, or the diversion groove completes the scraping of the excess raw material on the inner wall of the storage cylinder 4.

[0094] Working principle: When manufacturing culture medium raw materials, first unscrew the bolts from the circular plate 42 and pull the cap 43 out from the storage cylinder 4. Then, fill the corresponding amount of raw materials into the storage cylinder 4 through the mounting hole of the cap 43. After the raw materials are filled, the operator inserts the cap 43 back into the mounting hole of the storage cylinder 4 and fixes the cap 43 to the circular plate 42 with bolts. The feeding operation of raw materials in the storage cylinder 4 is completed.

[0095] After the raw material feeding operation is completed, the operator controls the main unit to open the electric valve. External water flows into the outer shell 1 through the pipe and the electric valve. After the electric valve is opened for the specified time, it closes. At this time, the corresponding amount of water is stored in the outer shell 1, and the water feeding operation in the outer shell 1 is completed.

[0096] After the preparation work before the use of the device is completed, the control host starts. The motor drives the storage cylinder 4 to rotate rapidly inside the outer shell 1 through the gear transmission mechanism and the gear ring. At this time, due to the push of the piston rod 82 by the spring 85, the flow divider 7 and the inner wall of the storage cylinder 4 generate a corresponding strength of resistance force, which in turn generates a corresponding strength of friction force between the flow divider 7 and the inner wall of the storage cylinder 4. At this time, the rotating storage cylinder 4 drives the flow divider 7, piston rod 82, piston cylinder 81 and round tube 6 to rotate synchronously.

[0097] During the rotation of the storage cylinder 4, the dispersed raw materials in the material are subject to centrifugal force and their own light weight, causing the raw materials to come into contact with the inner wall of the storage cylinder 4 and the raw materials to come into contact with each other, thus causing the dispersed raw materials to be subjected to a corresponding degree of friction. At this time, the dispersed raw materials adhere to the inner wall of the storage cylinder 4 and rotate with the raw materials. Meanwhile, the agglomerated raw materials in the material are subject to greater weight and always roll at the bottom of the storage cylinder 4. When the diversion pipe 7 and the piston rod 82 move to the bottom of the storage cylinder 4, the edge of the diversion pipe 7 and the outer arc wall of the piston rod 82 collide with the agglomerated raw materials, thereby breaking up the agglomerated raw materials.

[0098] After the raw materials are dispersed, the drive mechanism 5 slows down the rotation speed of the storage cylinder 4, so that the storage cylinder 4 rotates at a slower and uniform speed inside the outer shell 1. At this time, the dispersed raw materials at the bottom of the storage cylinder 4 continue to tumble, and when the diversion pipe 7 moves to the bottom of the storage cylinder 4, the raw materials inside can be pushed out due to the mutual contact between the piston rod 82 and the diversion pipe 7 and the raw materials, so that the various raw materials are mixed evenly.

[0099] After the raw materials are mixed, the gas pump 21 starts and continuously draws gas from the outer casing 1 through the gas heater 23 and connecting pipe, and injects it into the circular pipe 6 through the electrically controlled four-way valve 22. During this process, the gas heater 23 starts to heat the gas. The gas injected into the circular pipe 6 flows into the piston cylinder 81 through the exhaust port 841, outer pipe 842, inner pipe 843 and guide hole 83, so that a high-pressure chamber is formed in the piston cylinder 81 at the position on the outer periphery of the piston rod 82, thereby applying a thrust to the piston rod 82 towards the piston cylinder 81, so that the piston rod 82 gradually retracts into the piston cylinder 81 and compresses the spring 85. When the pressure in the piston cylinder 81 reaches the threshold, the pressure relief valve 8... When the pressure difference at both ends of 9 reaches the threshold, the gas flowing into the guide hole 83 passes through the pressure relief valve 89 and flows into the diversion pipe 7. The piston rod 82 will not continue to retract into the piston cylinder 81. At this time, there is a corresponding length of distance between the diversion pipe 7 and the inner wall of the piston cylinder 81. Meanwhile, due to the pushing of the spring 2 94 on the push rod 93, the ball 95 and the inner wall of the limiting groove 91 abut against each other. The round tube 6 and the diversion pipe 7 will not rotate with the storage cylinder 4. At this time, as the storage cylinder 4 rotates, the diversion pipe 7 abuts against the raw material. The diversion pipe 7 forms a scraper-like structure, scraping off the excess raw material on the inner wall of the storage cylinder 4, so that the raw material of the corresponding thickness is evenly spread on the inner wall of the storage cylinder 4.

[0100] After the gas flows into the distributor pipe 7, the amount of gas discharged from the exhaust port 841 of the distributor pipe 7 is limited. The gas injected into the distributor pipe 7 first diffuses within the distributor pipe 7 and is finally discharged from various locations at the opening of the distributor pipe 7, forming a linear airflow that blows onto the raw material. At this time, due to the loss of gas inside the outer shell 1, a pressure difference is formed inside and outside the mesh pipe 41. The gas blown onto the raw material flows into the outer shell 1 through the gaps between the raw materials and the holes of the mesh pipe 41 to replenish the gas lost in the outer shell 1. When the gas passes through the gaps between the raw materials, it can fully heat the raw materials.

[0101] After the distance between the diversion pipe 7 and the inner wall of the storage cylinder 4 reaches the threshold, the electrically controlled four-way valve 22 is activated, which connects the air pump 21 and the conduit 32. At this time, the gas drawn by the air pump 21 is injected into the area below the piston plate 31 through the electrically controlled four-way valve 22 and the conduit 32, thereby forming a high-pressure chamber below the piston plate 31, pushing the piston plate 31 upward to lift the water in the outer shell 1 until the water in the outer shell 1 passes through the holes of the mesh pipe 41 to soak the raw material at the bottom of the storage cylinder 4. As the storage cylinder 4 rotates, the raw material in the storage cylinder 4 is continuously soaked to replenish the moisture in the raw material while heating it. This allows the gas to generate more water vapor inside the raw material when heating it, further heating the raw material.

[0102] After the raw materials are heated and sterilized, the electrically controlled four-way valve 22 is activated, connecting the inside of the round pipe 6 with the inside of the conduit 32. At this time, due to the weight of the water pushing the piston plate 31, the piston plate 31 automatically moves down until the piston plate 31 contacts the inner wall of the outer shell 1. The water level in the outer shell 1 drops and separates from the storage cylinder 4. At the same time, the gas heater 23 stops the gas heating process. During the process of the gas passing through the connecting pipe, the gas continuously exchanges heat with the outside air through the connecting pipe, thereby gradually reducing the temperature of the circulating gas. As it passes through the gaps between the raw materials, it quickly carries away the heat from the raw materials to reduce their temperature. At the same time, when the gas blows on the raw materials, the small water droplets and water vapor carried in the gas come into contact with the raw materials and are absorbed by them to continuously replenish the moisture lost from the raw materials due to their own temperature.

[0103] It should be noted that when the raw materials need to contain a lot of moisture, or when the condensation droplets in the gas cannot replenish the water in the raw materials in time, the moisture in the raw materials can be replenished by soaking as described above, and the excess moisture in the raw materials can be shaken out by rotating the raw materials.

[0104] It should be noted that a water level sensor can also be installed inside the outer casing 1 to monitor the water content inside the outer casing 1, so that the water inside the outer casing 1 can be replenished in a timely manner by opening and closing the electronically controlled valve, so that the outer casing 1 always stores the corresponding amount of water.

[0105] After the raw materials are mixed and disinfected, the air pump 21 stops running and the driver gradually slows down the rotation speed of the storage cylinder 4. As the rotation speed of the storage cylinder 4 decreases, the raw materials slide off the inner wall of the storage cylinder 4 and settle at the bottom of the storage cylinder 4. Then, the cap 43 is removed according to the above procedure, and the raw materials can be taken out from the storage cylinder 4.

[0106] It should be noted that a scraper can be used to remove the raw material from the storage cylinder 4, or a telescopic support leg can be installed at the bottom of the device. By adjusting the support leg, the storage cylinder 4 can be tilted, so that the raw material can slide out of the storage cylinder 4 or in other ways.

[0107] After the device is used, when cleaning the device, the water inside the outer shell 1 is partially stored in the storage cylinder 4 as described above. Then, the drive mechanism 5 drives the storage cylinder 4 to rotate slowly inside the outer shell 1. The water washes down the material attached to the inner wall of the storage cylinder 4 and deposits it at the bottom of the storage cylinder 4 when the storage cylinder 4 stops rotating. By adjusting the water level inside the outer shell 1, almost all the wastewater inside the outer shell 1 can be discharged through the electric control valve.

[0108] When cleaning the raw materials adhering to the inner wall of the storage cylinder 4, the contact force between the diversion pipe 7 and the inner wall of the storage cylinder 4 can be adjusted by adjusting the amount of gas in the piston cylinder 81. This allows the diversion pipe 7 to slide against the inner wall of the storage cylinder 4 when the storage cylinder 4 rotates, simulating the scraping operation of a scraper, so as to scrape off the raw materials on the inner wall of the storage cylinder 4 that cannot be washed down by water.

[0110] S1: The filling of raw materials into the storage cylinder 44 is completed by disassembling and assembling the cap 4343 and the corresponding circular plate 4242;

[0111] S2: The rotation of the storage cylinder 44 causes the diversion pipe 77 and piston rod 8282 to collide with the agglomerated raw material, breaking up the agglomerated raw material;

[0112] S3: The raw materials are mixed by rotating and turning the storage cylinder 44;

[0113] S4: The raw material is laid on the inner wall of the storage cylinder 44 by rotating the storage cylinder 44 in conjunction with the scraping operation of the diversion pipe 77. Then, the raw material is disinfected at high temperature by the high temperature gas discharged by the air circulation heating mechanism 22 and the water in the outer shell 11.

[0114] S5: The temperature of the gas blown onto the raw material is gradually reduced by the gas circulation heating mechanism 22, thereby completing the rapid cooling process of the raw material.

[0115] S6: Stop the operation of the device, and remove the processed raw material from the storage cylinder 44 by disassembling and assembling the cover 4343 and the corresponding circular plate 4242;

[0116] In this embodiment, the culture medium raw material processing flow in the improved edible fungus strain method is easy to operate, does not require the replacement of multiple pieces of equipment, and has high processing efficiency.
