The above fungi grow in different regions and different ecological environments.
[0004] Currently, the production steps for edible fungi are: material preparation → soaking → fermentation → insect control → mixing → bagging → sterilization → inoculation, etc. Among them, material preparation, soaking, fermentation, insect control and mixing are completed using one piece of equipment, while bagging and sterilization are completed using separate equipment. The production process is complicated and the equipment is scattered, resulting in long production cycles, high costs, low efficiency, and the risk of contamination from multiple material transfers.

[0038] It should be noted that, where there is no conflict, the embodiments and features described in these embodiments can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0039] like Figure 1 , Figure 2 As shown, this utility model provides a fully automatic edible mushroom substrate production device, including a machine body 11. The machine body 11 is supported and installed on the ground by support legs or brackets, and the inside of the machine body 11 is a material hopper 12, which is used to process the materials required for edible mushroom substrate. The outer wall of the machine body 11 has a sandwich structure 13, which can cool or heat the materials according to the needs of material processing. A return mixing screw 3 is installed in the material hopper 12. The central shaft of the return mixing screw 3 is rotatably and sealed on the machine body 11 through a bearing seat. The return mixing screw 3 has a forward propeller blade 31 and a return propeller blade 32. The forward propeller blade 31 and the return propeller blade 32 are installed on the central shaft of the return mixing screw 3 by support rods, and the spiral directions of the forward propeller blade 31 and the return propeller blade 32 are opposite. The diameters of the forward propeller blade 31 and the return propeller blade 32 are different, but the forward propeller blade 31 and the return propeller blade 32 are of different diameters. The central axes of the propeller blade 31 and the return propeller blade 32 are both on the same straight line as the central axis of the return mixing screw 3. When the material is processed in the hopper 12, the central axis of the return mixing screw 3 drives the forward propeller blade 31 and the return propeller blade 32 to rotate. While rotating, the forward propeller blade 31 and the return propeller blade 32 convey and compress the material from two opposite directions, so that the material is mixed in the hopper 12, resulting in a better mixing effect.
[0040] The lower part of the machine body 11 is also equipped with a water pipe 6 connected to the hopper 12. The water pipe 6 runs through the lowest point of the hopper 12, which facilitates the drainage of all water in the hopper 12 later. The lower part of the machine body 11 is also equipped with a discharge pipe 4 connected to the hopper 12. The discharge pipe 4 is located at one end of the pull-back mixing screw 3 and is used to send the processed material out of the hopper 12. The machine body 11 is also equipped with a steam conveying pipe 1 connected to the hopper 12. The outlet of the steam conveying pipe 1 is located in the middle of the height direction of the hopper 12. The steam conveying pipe 1 is used to convey high-temperature steam or clean air into the hopper 12 to meet the needs of material softening and inoculation. The top of the machine body 11 is also equipped with a spray pipe 8. The spray pipe 8 can spray the bacterial solution onto the material in the hopper 12 in a spraying manner to achieve inoculation.
[0041] In this invention, the retractable mixing screw 3 has two forward-pushing propeller blades 31 and one retractable propeller blade 32. The lengths of the two forward-pushing propeller blades 31 and the retractable propeller blade 32 are the same, but their diameters are different. The diameter of the retractable propeller blade 32 is between the diameters of the two forward-pushing propeller blades 31. That is, arranged in ascending order of diameter: forward-pushing propeller blade 31, retractable propeller blade 32, forward-pushing propeller blade 31. This ensures that when the retractable mixing screw 3 rotates, the material located around the central axis of the retractable mixing screw 3 moves in one direction, while the material located between the two forward-pushing propeller blades 31 moves in the other direction, ensuring both the extrusion and mixing effects of the material. When there are two forward-pushing propeller blades 31, the inlet end of the discharge pipe 4 is located at the output end of the forward-pushing propeller blade 31.
[0042] Of course, in this invention, the number of pull-back mixing screws 3 can be adjusted according to the actual situation. That is, the number of pull-back mixing screws 3 in the hopper 12 can be 1, 2, 3, or 4. When there are multiple pull-back mixing screws 3 in the hopper 12, the multiple pull-back mixing screws 3 can be divided into multiple groups and arranged vertically, or the multiple pull-back mixing screws 3 can be evenly spaced along the width direction of the hopper 12.
[0043] To ensure that the bacterial solution is evenly sprayed onto the material in the silo 12, multiple atomizing nozzles 9 are installed on the spray pipe 8. The multiple atomizing nozzles 9 are evenly spaced along the length of the silo 12, and the spraying area of the multiple atomizing nozzles 9 covers the projected surface of the silo 12, so that the multiple atomizing nozzles 9 can cover the surface layer of the material when spraying the bacterial solution, making the dispersion of the bacterial solution more uniform.
[0044] To ensure the rotation of the retractable mixing screw 3, a drive motor 2 is bolted to the outer wall of the machine body 11. One end of the central shaft of the retractable mixing screw 3 passes through the machine body 11 and is connected to the output end of the drive motor 2, so that the drive motor 2 drives the retractable mixing screw 3 to rotate simultaneously. In this invention, when there are multiple retractable mixing screws 3 in the hopper 12, the number of drive motors 2 can be one, or the number of drive motors 2 can be equal to the number of retractable mixing screws 3. When there is only one drive motor 2, the central shafts of the multiple retractable mixing screws 3 are driven by gears or chains. When the number of drive motors 2 is equal to the number of retractable mixing screws 3, each drive motor 2 drives one retractable mixing screw 3.
[0045] To minimize the entry of dust and other impurities from the air into the hopper 12, a cover plate is provided on the top of the machine body 11. The cover plate also has a feed inlet 7, which allows materials to be fed into the hopper 12 through the feed inlet 7, ensuring the feeding of materials.
[0046] To prevent staff from being burned during operation, the machine body 11 is also wrapped with a heat-insulating and anti-scalding felt 10. The thickness of the heat-insulating and anti-scalding felt 10 can be selected according to the actual situation.
[0047] To facilitate the efficient delivery of processed materials out of the hopper 12, the machine body 11 can be configured with a V-shaped bottom for the hopper 12, and the bottom of the hopper 12 can be arc-shaped. The arc of the bottom of the hopper 12 is adapted to the large-diameter forward-pushing propeller blade 31, ensuring that the forward-pushing propeller blade 31 can squeeze and convey the material at the bottom of the hopper 12 when rotating. This not only ensures the uniformity of material mixing but also ensures that the processed material can be delivered out of the hopper 12. When there are multiple pullback mixing screws 3 and the bottom of the hopper 12 is set in a V-shape, one of the pullback mixing screws is located at the bottom of the hopper 12, and the large-diameter forward-pushing propeller blade 31 on this pullback mixing screw is adapted to the arc of the bottom of the hopper 12.
[0048] To facilitate the transfer of materials from the discharge hopper 12 to the bagging equipment, a screw conveyor is also connected to the outlet end of the discharge pipe 4. The screw conveyor can directly transfer the materials from the discharge hopper 12 to the bagging equipment, so that the production, processing and bagging of materials do not require manual operation, greatly reducing manual intervention and the risk of pollution.
[0049] To facilitate monitoring of the liquid level and temperature in the silo 12, a liquid level sensor 25 is also installed on the machine body 11. The liquid level sensor 25 can monitor the height of the water entering the silo 12 to prevent the water in the silo 12 from being too much or too little. The temperature sensor 24 is used to monitor the temperature of the material in the silo 12 in real time to prevent the material temperature from being too high or too low, so that the softening effect of the material and the inoculation effect of the bacteria can be guaranteed, and the material is prevented from being over-softened or the bacteria are damaged.
[0050] To enable rapid cooling of the material after softening or to ensure that the inoculum remains within a suitable inoculation temperature during inoculation, an insulated water storage tank 5 is installed on one side or the top of the machine body 11. The insulated water storage tank 5 stores the heat exchange medium used in the sandwich structure 13, which is water. An electric heating rod 18 and a water pump 17 are also installed in the insulated water storage tank 5. The electric heating rod 18 is used to heat the heat exchange medium in the water storage tank, while the water pump 17 is used to pump the heating medium in the insulated water storage tank 5. Cooling pipes are installed in the sandwich structure 13 of the machine body 11. The cooling pipes are spirally arranged on the outer wall of the silo 12. The end of the cooling pipe near the bottom of the silo 12 is connected to the outlet of the water pump 17 through a pipe, and the end of the cooling pipe near the top of the silo 12 is connected to an external water storage device through a pipe. Pump 17 pumps water from the insulated water tank 5 into the sandwich structure 13. The water in the sandwich structure 13 exchanges heat with the material in the silo 12, cooling the material in the silo 12. The water that has completed the heat exchange in the sandwich structure 13 is then discharged into an external water storage device through a pipeline for subsequent use and heat recovery.
[0051] To achieve automated control, such as Figure 2 , Figure 3 As shown, a high-temperature steam valve 19 for controlling the opening and closing of the steam conveying pipe 1 is installed at the inlet end; a valve A20 for controlling the opening and closing of the spray pipe 8 is installed at the inlet end; a valve B21 for controlling the opening and closing of the water pipe 6 is installed on the water pipe 6; and a valve C23 for controlling the opening and closing of the discharge pipe 4 is installed on the discharge pipe 4. The high-temperature steam valve 19, valve A20, valve B21, and valve C23 are all directly used existing electric control valves. An electrical control box 14 is also installed on the machine body 11. A control module 16 is installed inside the electrical control box 14, and a display module 15 is embedded on the surface of the electrical control box 14. The display module 15 and the control module 16 are bidirectionally electrically connected. Operators can input relevant parameters through the display module 15, and the display module 15 transmits the relevant parameters set by the operator to the control module 16. The control module 16 can also transmit the working status of each component and the specific parameters of the device operation to the display module 15 for display.
[0052] In this invention, the output terminals of the liquid level sensor 25 and the temperature sensor 24 are both electrically connected to the input terminal of the control module 16, so that the liquid level signal detected by the liquid level sensor 25 and the temperature signal detected by the temperature sensor 24 are transmitted to the control module 16. The control module 16 converts the received liquid level signal and temperature signal into liquid level height value and temperature value, and transmits the liquid level height value and temperature value to the display module 15 for display, so that the staff can know the liquid level height and temperature in the silo 12 by observing the display module 15.
[0053] In this invention, the output terminal of the control module 16 is also connected to the relays corresponding to valve A20, valve B21, valve C23, high-temperature steam valve 19, water pump 17, drive motor 2, and electric heating rod 18, respectively. The control module 16 can control the start and stop of valve A20, valve B21, valve C23, high-temperature steam valve 19, water pump 17, drive motor 2, and electric heating rod 18 by sending start and stop signals to the relays corresponding to valve A20, valve B21, valve C23, high-temperature steam valve 19, water pump 17, drive motor 2, and electric heating rod 18.
[0054] Based on the aforementioned fully automated edible mushroom substrate production device, this utility model also provides a fully automated edible mushroom substrate production method, comprising the following steps:
[0055] S1. The mixed material is fed into the silo 12 through the feed inlet 7. The operator inputs the start command of the drive motor 2 to the control module 16 through the display module 15. After receiving the start command, the control module 16 sends the start command to the relay corresponding to the drive motor 2. After receiving the start command, the relay corresponding to the drive motor 2 is powered on and the drive motor 2 starts to run. While the drive motor 2 is running, it drives the pullback mixing screw 3 to rotate synchronously. The forward propeller blade 31 on the pullback mixing screw 3 squeezes the material forward while rotating, and the pullback propeller blade 32 squeezes the material backward while rotating, so that the material rotates in the silo 12.
[0056] S2. Control module 16 sends a start command to the relay corresponding to valve B21. After receiving the start command, the relay corresponding to valve B21 energizes valve B21, opening it and allowing water to enter the silo 12 through water pipe 6. During the water entry into silo 12, level sensor 25 continuously monitors the water level and transmits the detected water level signal to control module 16. Control module 16 converts the water level signal into a water level value and compares it with a preset high water level value. When the water level value detected by level sensor 25 equals the preset high water level value, control module 16 sends a close command to the relay corresponding to valve B21, opening the valve. After the relay corresponding to door B21 receives the closing command, valve B21 is de-energized and closed. Then, the control module 16 sends a start command to the relay corresponding to the high-temperature steam valve 19. After receiving the start command, the high-temperature steam valve 19 is energized and opened. High-temperature steam enters the silo 12 through the steam conveying pipe 1. The high-temperature steam in the silo 12 heats and cooks the material in the silo 12. During this process, the material is stirred and mixed by the pull-back mixing screw 3. The material is rubbed and squeezed while being mixed, which makes the wood in the material soften quickly, thereby replacing the traditional time-consuming soaking and fermentation.
[0057] S3. After the material softens, the control module 16 sends a start command to the relay corresponding to valve B21. Upon receiving the start command, the relay corresponding to valve B21 energizes valve B21, opening it. Water in silo 12 is pumped to storage equipment through water pipe 6. During this process, the liquid level sensor 25 detects the water level in silo 12 in real time and transmits the detected water level signal to the control module 16. The control module 16 converts the water level signal into a water level value and compares it with a preset low water level value. When the water level value detected by the liquid level sensor 25 is equal to the preset low water level value, the control module 16 sends a close command to the relay corresponding to valve B21. Upon receiving the close command, the relay corresponding to valve B21 de-energizes valve B21, closing it. Simultaneously, high-temperature steam delivered to silo 12 through steam conveying pipe 1 continues to cook the material in silo 12. Combined with the mixing screw 3, the material is stirred and mixed to ensure that the drained material is heated evenly, achieving high-temperature sterilization and insecticidal treatment.
[0058] S4. When the opening time of the high-temperature steam valve 19 reaches the preset time, the control module 16 sends a closing command to the relay corresponding to the high-temperature steam valve 19. After receiving the closing command, the relay corresponding to the high-temperature steam valve 19 de-energizes and closes, thereby stopping the delivery of steam to the silo 12. Next, the control module 16 sends a start command to the relay corresponding to the water pump 17. After receiving the start command, the relay corresponding to the water pump 17 energizes the water pump 17 and starts running. The water pump 17 delivers the cooling water in the insulated water storage tank 5 to the jacket structure, allowing the cooling water to flow along the jacket structure. The water entering the jacket structure 13 exchanges heat with the material in the silo 12, thus... The material in the silo 12 is cooled down. During the cooling process, the material is stirred and mixed by the pull-back mixing screw 3 to ensure the uniformity of the material cooling. During this process, the temperature sensor 24 detects the temperature in the silo 12 in real time and transmits the detected temperature signal to the control module 16. The control module 16 converts the temperature signal into a temperature value and compares the temperature value with the preset temperature value. When the temperature value detected by the temperature sensor 24 is equal to the preset temperature value, the control module 16 sends a stop command to the relay corresponding to the water pump 17. After receiving the stop command, the relay corresponding to the water pump 17 cuts off the power to the water pump 17 and stops running. The cooling water in the heat preservation water storage tank 5 stops entering the jacket structure.
[0059] S5. Control module 16 sends a start command to the relay corresponding to valve A20. After receiving the start command, the relay corresponding to valve A20 energizes valve A20, opening it. The bacterial solution enters the atomizing nozzle 9 through the spray pipe 8. The atomizing nozzle 9 sprays the bacterial solution onto the material in the hopper 12, and, in conjunction with the pull-back mixing screw 3, mixes the material thoroughly. When the opening time of valve A20 reaches the preset time, control module 16 sends a close command to the relay corresponding to valve A20. After receiving the close command, the relay corresponding to valve A20 energizes valve A20, opening it. When power is cut off at 20, valve A20 closes, thus stopping the spraying of bacterial solution into silo 12. During the spraying process, control module 16 sends a start command to the relay corresponding to high-temperature steam valve 19. After receiving the start command, the relay corresponding to high-temperature steam valve 19 is energized and opens. Outside air enters silo 12 through steam delivery pipe 1. The air entering silo 12 acts evenly on the material in silo 12. During this process, the mixing of the material is coordinated with the pull-back mixing screw 3, which ensures both the uniformity of inoculation and the activity of the bacteria.
[0060] S6. After valve A20 has been closed for a certain period of time, the bacterial solution and material are mixed evenly. At this time, the control module 16 sends a start command to the relay corresponding to valve C23. After receiving the start command, the relay corresponding to valve C23 is energized and valve C23 is opened. While the pullback mixing screw 3 is rotating, the material pushed forward by the propeller blade 31 of the pullback mixing screw 3 enters the discharge pipe 4 and enters the screw conveyor through the discharge pipe 4. It is then transported to the bagging equipment by the screw conveyor.
[0061] In this invention, the material used for producing the microbial spawn is a mixture of sawdust, cottonseed, and wheat bran. The high-temperature steam, transported to the silo 12 via the steam conveying pipe 1, has a temperature of 120°C to 180°C. Preferably, the high-temperature steam temperature is 120°C. The temperature of the material in the silo 12 is maintained between 25°C and 28°C during the mixing process with the microbial solution. In this invention, when water needs to be injected into the silo 12 to steam and soften the material, the water level in the silo 12 can be adjusted according to the actual situation. For example, when the silo 12 is full, the water level is half the volume of the silo 12. When the silo 12 is not full, the water level can be determined based on the volume of the material in the silo 12.
[0062] In this invention, when the high-temperature steam valve 19 is opened and high-temperature steam enters the silo 12 through the steam delivery pipe 1, the temperature sensor 24 also detects the temperature inside the silo 12 in real time and transmits the detected temperature signal to the control module 16. The control module 16 converts the temperature signal into a temperature value and transmits the temperature value obtained by the control module 16 to the display module 15. The display module 15 displays the temperature value, thereby facilitating the monitoring of the temperature inside the silo 12 by the staff.
[0063] In this invention, when the production equipment is used in winter, in order to maintain the material temperature in the silo 12 within a certain range during the cooling process, the control module 16 sends a start command to the relay corresponding to the electric heating rod 18 when the material in the silo 12 cools down to the required temperature. Upon receiving the start command, the relay corresponding to the electric heating rod 18 is energized and turns on. During this process, the control module 16 sends a start command to the relay corresponding to the water pump 17. Upon receiving the start command, the relay corresponding to the water pump 17 is energized and starts running. 7. Cooling water from the insulated water storage tank 5 is transported to the jacket structure, allowing it to flow along the jacket structure. The water entering the jacket structure 13 exchanges heat with the material in the hopper 12, maintaining the material in the hopper 12 within the required temperature range. During this process, when the temperature sensor 24 detects that the temperature in the hopper 12 has reached the preset temperature, the control module 16 sends a stop command to the relays corresponding to the electric heating rod 18 and the water pump 17. Upon receiving the start command, the relays corresponding to the electric heating rod 18 and the water pump 17 de-energize and stop operating. This process is repeated to ensure that the material in the hopper 12 remains within a fixed temperature range during inoculation of the microorganisms when the equipment is used in winter, thus ensuring the activity of the microorganisms.
[0064] In this invention, since the steam delivery pipe 1 needs to simultaneously transport high-temperature steam and natural air, its inlet end needs to be connected in parallel to a steam boiler and a blower. To facilitate control of the high-temperature steam or blower transport, electric control valves are installed on the steam output pipe of the steam boiler and the outlet end of the blower. The blower and the two electric control valves are simultaneously electrically connected to the control module 16. When high-temperature steam is needed, the control module 16 sends a start command to the relay of the high-temperature steam valve 19, and simultaneously sends a start command to the relay of the electrically controlled valve on the steam output pipe, causing the high-temperature steam valve 19 and the electrically controlled valve on the steam output pipe to open simultaneously. When high-temperature steam is not needed, the control module 16 sends a stop command to the relay of the high-temperature steam valve 19, and simultaneously sends a stop command to the relay of the electrically controlled valve on the steam output pipe, causing the high-temperature steam valve 19 and the electrically controlled valve on the steam output pipe to close simultaneously. When outside air is needed, the control module 16 sends a start command to the relay of the high-temperature steam valve 19, and simultaneously sends a start command to the relay of the electrically controlled valve at the blower outlet, causing the high-temperature steam valve 19 and the electrically controlled valve at the blower outlet to open simultaneously. When outside air is not needed, the control module 16 sends a stop command to the relay of the high-temperature steam valve 19, and simultaneously sends a stop command to the relay of the electrically controlled valve at the blower outlet, causing the high-temperature steam valve 19 and the electrically controlled valve at the blower outlet to close simultaneously.
[0065] In this invention, to ensure the replenishment of cooling water in the insulated water storage tank 5, the insulated water storage tank 5 can be directly connected to the water supply pipe 6. The replenishment of water in the insulated water storage tank 5 is controlled by opening and closing the valve on the water supply pipe 6. Alternatively, to facilitate automatic replenishment of water to the insulated water storage tank 5, the outlet end of the water supply pipe 6 can be installed inside the insulated water storage tank 5, and a float valve can be installed at the outlet end of the water supply pipe 6. The float valve can be opened or closed based on changes in the water level in the insulated water storage tank 5, thereby maintaining the water level in the insulated water storage tank 5 at a constant height. Since the method of replenishing water to the insulated water storage tank 5 is a direct application of existing technology, it will not be described in detail here.
[0066] In this utility model, in order to ensure that the high-temperature steam entering the silo 12 during the cooking and sterilization process is discharged from the feed inlet 7, a switch door can also be installed at the feed inlet 7. The opening and closing of the switch door can be manually operated or an automatic mechanism can be set up. The automatic mechanism that drives the switch door to open and close can be an existing structure such as a cylinder, which will not be described in detail here.
