Description

Technical Field

[0001] This utility model relates to the field of environmental protection equipment technology, and in particular to a fermentation device and fermentation equipment. Background Technology

[0002] Large-scale farms generate large amounts of manure daily, requiring aerobic fermentation in fermentation devices for harmless treatment and resource utilization. However, the fermentation process produces significant amounts of water vapor, leading to excessive humidity within the device and hindering fermentation efficiency. Therefore, a fermentation device and equipment are urgently needed to reduce humidity and improve fermentation effectiveness. Utility Model Content

[0003] In view of the above-mentioned problems of the prior art, this application provides a fermentation device and fermentation equipment, which can reduce the humidity of the air in the fermentation device during the fermentation process and improve the fermentation effect of the material.

[0004] The first aspect of this application provides a fermentation apparatus, comprising: a frame; a fermentation tank disposed on the frame; and a dehumidifier having an air inlet, an air outlet, a first heat exchanger, and a second heat exchanger. The air inlet is connected to one end of the fermentation tank, and the air outlet is connected to the other end of the fermentation tank. Air entering through the air inlet exchanges heat with the first heat exchanger to cool down, causing water vapor in the air to condense into condensate. Air that has exchanged heat with the first heat exchanger exchanges heat with the second heat exchanger to heat up and is discharged from the air outlet. The first heat exchanger and the second heat exchanger are connected through a second refrigerant pipeline, enabling refrigerant circulation between them.

[0005] As described above, by installing a dehumidifier and connecting its air inlet and outlet to the fermentation tank, the first heat exchanger cools the incoming air, causing water vapor to condense into water, thus reducing humidity. The second heat exchanger then heats the air, allowing it to return to the fermentation tank through the outlet, minimizing the impact of the cold air on the fermentation temperature. Therefore, while reducing humidity, the fermentation temperature within the tank is stabilized, ensuring both material dryness and sterilization effectiveness.

[0006] In addition, the first heat exchanger that cools the air and the second heat exchanger that heats the air are connected by a refrigerant pipeline. This means that the same refrigerant is used to first absorb heat from the air and then the heat obtained from this heat absorption is used to release heat from the air, thereby improving energy utilization efficiency and efficiently performing the fermentation process.

[0007] As one possible implementation of the first aspect, the fermenter includes a tank body, a first end cap, and a second end cap. The tank body is cylindrical and horizontally mounted on the frame, and can rotate on the frame about the axis of the tank body. The first end cap and the second end cap are fixed on the frame and are rotatably connected to both ends of the tank body, respectively, and close both ends of the tank body. The air inlet and the air outlet are respectively connected to the pipes of the first end cap and the second end cap.

[0008] As described above, by connecting the air inlet and outlet to the fixed first and second end cap pipes, the position of the air inlet and outlet connected to the inside of the tank remains unchanged when the tank rotates. This prevents the tank rotation from affecting the dehumidifier's air intake and exhaust.

[0009] As one possible implementation of the first aspect, the second end cap is provided with a feed inlet, through which the material enters the fermenter.

[0010] As described above, since the air outlet is connected to the pipe on the second end cover, by setting the feed inlet on the second end cover, the material entering the fermentation tank through the feed inlet can come into contact with the dry, hot air blown out from the air outlet, thus allowing the material to reach the fermentation temperature as quickly as possible after entering the fermentation tank. This improves fermentation efficiency and enhances the fermentation effect.

[0011] As one possible implementation of the first aspect, the air inlet and the air outlet are located above the axis of the fermentation tank.

[0012] As described above, by placing the air inlet and outlet above the tank's axis, the material inside the tank can prevent them from blocking the connection points. This ensures the dehumidifier's dehumidification effect on the air inside the tank, thereby improving the fermentation effect of the material.

[0013] As one possible implementation of the first aspect, the dehumidifier further includes: a first energy-saving device, which is disposed between the air inlet and the first heat exchanger, so that air flows from the air inlet through the first energy-saving device and then to the first heat exchanger; and a second energy-saving device, which is disposed between the first heat exchanger and the second heat exchanger, so that air flows through the second energy-saving device and then to the second heat exchanger; wherein the first energy-saving device and the second energy-saving device are connected by a second refrigerant pipeline, so that refrigerant circulation can occur between them.

[0014] As described above, by placing the first energy-saving device between the air inlet and the first heat exchanger, the air entering through the inlet (hot and humid air) exchanges heat with the first energy-saving device before entering the first heat exchanger for cooling, thus reducing the workload of the first heat exchanger and lowering energy consumption. After the first energy-saving device heats up the air through heat exchange, it transfers the heated heat exchange medium to the second energy-saving device. By placing the second energy-saving device between the first and second heat exchangers, the air cooled by heat exchange with the first heat exchanger (dry and cold air) first exchanges heat with the second energy-saving device. The second energy-saving device recovers waste heat to heat up the air, and then exchanges heat with the second heat exchanger for further heating, thus reducing the workload of the second heat exchanger and lowering energy consumption. After the second energy-saving device cools down the air through heat exchange, it transfers the cooled heat exchange medium back to the first energy-saving device, thus forming a cycle.

[0015] As one possible implementation of the first aspect, the dehumidifier is located at the other end near the fermentation tank; the dehumidifier also includes a compressor and an expansion valve, the compressor, the expansion valve, the first heat exchanger and the second heat exchanger are connected by a refrigerant pipeline to form a refrigerant circulation path, the first heat exchanger is an evaporator and the second heat exchanger is a condenser.

[0016] Therefore, by placing the dehumidifier closer to the other end of the fermentation tank, the length of the duct between the air outlet and the fermentation tank can be reduced, thereby minimizing heat loss during air transport. This, in turn, increases the temperature of the air entering the fermentation tank from the air outlet, thus improving the fermentation effect.

[0017] As one possible implementation of the first aspect, the temperature of the air after heat exchange and cooling with the first heat exchanger is 20°C-30°C.

[0018] As mentioned above, by cooling the air to 20℃-30℃ after heat exchange with the first heat exchanger, the condensation effect of water vapor can be improved, thereby enhancing the dehumidification effect.

[0019] As one possible implementation of the first aspect, the temperature of the air after heat exchange with the second heat exchanger is 60°C-75°C.

[0020] As described above, by exchanging heat with the second heat exchanger to raise the temperature of the air to 60℃-75℃, the air can return to the tank and maintain the temperature required for fermentation, thereby improving the fermentation effect.

[0021] As one possible implementation of the first aspect, the temperature of the air entering through the air inlet is 40°C-50°C.

[0022] As shown above, the temperature of the air entering through the inlet is 40℃-50℃, meaning the temperature of the air inside the tank is also 40℃-50℃. This maintains the necessary temperature for fermentation within the tank, thereby improving the fermentation effect. Furthermore, since the air temperature entering through the inlet is 40℃-50℃, the temperature of the air after heat exchange and cooling with the first heat exchanger is 20℃-30℃. This ensures sufficient cooling of the air during heat exchange with the first heat exchanger, thereby improving the condensation effect of water vapor and enhancing the dehumidification effect.

[0023] The second aspect of this application provides a fermentation apparatus, comprising: a fermentation device, wherein the fermentation device is the same as described in any one of the first aspects of this application; and a separator, wherein the separator is used to dehydrate the material and transport the dehydrated material to the tank of the fermentation device.

[0024] As described above, by installing a dehumidifier with its inlet and outlet connected to the tank, air from inside the tank is driven into the dehumidifier through the inlet for dehumidification, and then the dry air is sent back into the tank through the outlet. This reduces the humidity inside the tank, thereby improving the fermentation effect of the material. Additionally, by installing a separator to dehydrate the material, the moisture content can be reduced, facilitating fermentation within the fermentation tank of the fermentation device.

[0025] As one possible implementation of the second aspect, the separator is provided in multiple ways.

[0026] As mentioned above, by setting up multiple separators, the speed of dehydration of materials can be increased, thereby increasing the speed at which materials are supplied to the tank.

[0027] As a possible implementation of the second aspect, the fermentation equipment further includes a conveyor belt for transporting the fermented material to a storage area.

[0028] As mentioned above, by setting up a conveyor belt to transport the fermented material from the fermentation device to the storage area, it is possible to avoid the fermented material from accumulating at the outlet of the fermentation device and affecting the normal operation of the fermentation device.

[0029] These and other aspects of this invention will become more readily apparent in the following description of several embodiments. Attached Figure Description

[0039] Below, with reference to the accompanying drawings, possible embodiments of the fermentation apparatus 100 in this application will be described by way of example.

[0040] like Figure 1 , Figure 2 As shown, this application provides a fermentation apparatus 100, including a frame 110, a fermentation tank 120, and a dehumidifier 130. The fermentation tank 120 is mounted on the frame 110. The dehumidifier 130 has an air inlet 131, an air outlet 132, a first heat exchanger 133, and a second heat exchanger 134. The air inlet 131 is connected to one end of the fermentation tank 120, and the air outlet 132 is connected to the other end of the fermentation tank 120. Air entering through the air inlet 131 exchanges heat with the first heat exchanger 133, causing water vapor in the air to condense into condensate. Air that has exchanged heat with the first heat exchanger 133 exchanges heat with the second heat exchanger 134, increasing its temperature, and is discharged through the air outlet 132. The first heat exchanger 133 and the second heat exchanger 134 are connected by a first refrigerant pipeline, enabling refrigerant circulation between them.

[0041] As described above, by installing a dehumidifier 130, with its air inlet 131 and outlet 132 connected to the fermentation tank 120, the first heat exchanger 133 can cool the air entering through the air inlet 131, causing water vapor in the air to condense into condensate, thereby reducing the air humidity. Then, the second heat exchanger 134 heats the air, allowing the warmed, dry air to return to the fermentation tank 120 through the outlet 132, reducing the impact of the low-temperature air on the fermentation temperature within the fermentation tank 120. Thus, while reducing the air humidity within the fermentation tank 120, the fermentation temperature within the fermentation tank 120 can be stabilized, ensuring both the dryness of the material and the sterilization effect.

[0042] like Figure 1As shown, in some embodiments, the fermentation tank 120 includes a tank body 121, a first end cap 122, and a second end cap 123. The tank body 121 is cylindrical and horizontally mounted on a frame 110, allowing it to rotate around its axis on the frame 110. The first end cap 122 and the second end cap 123 are fixed to the frame 110 and rotatably connected to both ends of the tank body 121, respectively, sealing both ends. An air inlet 131 and an air outlet 132 are respectively connected to the first end cap 122 and the second end cap 123 via pipes. Therefore, by connecting the air inlet 131 and the air outlet 132 to the fixed first end cap 122 and the second end cap 123 via pipes, the position of the air inlet 131 and the air outlet 132 communicating with the interior of the tank body 121 remains unchanged when the tank body 121 rotates. This prevents the rotation of the tank body 121 from affecting the air intake and exhaust of the dehumidifier 130.

[0043] like Figure 1 As shown, in some embodiments, the second end cap 123 is provided with a feed inlet 124, through which the material enters the fermentation tank 120. Since the air outlet 132 is pipe-connected to the second end cap 123, by placing the feed inlet 124 on the second end cap 123, the material entering the fermentation tank 120 through the feed inlet 124 can come into contact with the dry, hot air blown out by the air outlet 132, thus allowing the material to reach the fermentation temperature as quickly as possible after entering the fermentation tank 120. This improves fermentation efficiency and enhances the fermentation effect.

[0044] like Figure 1 As shown, in some embodiments, the air inlet 131 and air outlet 132 are located above the axis of the fermentation tank 120, communicating with each other. Specifically, they are located above the first end cover 122 and the second end cover 123, in the upper 1 / 3 of the height direction of the first end cover 122 and the second end cover 123. Therefore, by placing the air inlet 131 and air outlet 132 at the upper part of the tank 121, the material inside the tank 121 can be prevented from blocking the air inlet 131 and air outlet 132, thus ensuring the dehumidification effect of the dehumidifier 130 on the air inside the tank 121, and thereby improving the fermentation effect of the material.

[0045] like Figure 3As shown, in some embodiments, the dehumidifier 130 further includes a first energy-saving device 137 and a second energy-saving device 138. The first energy-saving device 137 is disposed between the air inlet 131 and the first heat exchanger 133, allowing air to flow from the air inlet 131 through the first energy-saving device 137 before flowing to the first heat exchanger 133. The second energy-saving device 138 is disposed between the first heat exchanger 133 and the second heat exchanger 134, allowing air to flow through the second energy-saving device 138 before flowing to the second heat exchanger 134. The first energy-saving device 137 and the second energy-saving device 138 are connected by a second refrigerant pipeline, enabling refrigerant circulation between them. By disposing of the first energy-saving device 137 between the air inlet 131 and the first heat exchanger 133, the air entering through the air inlet 131 (high-temperature, humid air) can exchange heat with the first energy-saving device 137 before entering the first heat exchanger 133 for cooling, thus reducing the workload of the first heat exchanger 133 and consequently reducing energy consumption. After the first energy-saving device 137 exchanges heat with the air and heats it up, the heated heat exchange medium is then transported to the second energy-saving device 138. By placing the second energy-saving device 138 between the first heat exchanger 133 and the second heat exchanger 134, the air (dry, cold air) that has been cooled down by heat exchange with the first heat exchanger 133 first exchanges heat with the second energy-saving device 138, raising its temperature. Then, the air exchanges heat with the second heat exchanger 134, raising its temperature further. This reduces the workload of the second heat exchanger 134, thereby reducing energy consumption. After the second energy-saving device 138 cools down by heat exchange with the air, the cooled heat exchange medium is then transported back to the first energy-saving device 137, thus forming a cycle.

[0046] In some embodiments, the refrigerant in the first refrigerant line and / or the second refrigerant line may be, for example, a hydrofluorocarbon refrigerant, a hydrofluoroolefin refrigerant, a hydrocarbon refrigerant, a mixed refrigerant, or other suitable refrigerant.

[0047] like Figure 1 As shown, in some embodiments, the dehumidifier 130 is positioned at the other end near the fermentation tank 120. The dehumidifier 130 also includes a compressor 135 and an expansion valve 136. The compressor 135, expansion valve 136, first heat exchanger 133, and second heat exchanger 134 are connected via refrigerant piping to form a refrigerant circulation path. The first heat exchanger 133 is an evaporator, and the second heat exchanger 134 is a condenser. Therefore, by positioning the dehumidifier 130 at the other end near the fermentation tank 120, the length of the pipe between the air outlet 132 and the fermentation tank 120 can be reduced, thereby reducing heat loss during air transport in the pipe. This increases the temperature of the air entering the fermentation tank 120 from the air outlet, thereby improving the fermentation effect.

[0048] like Figure 3As shown, in some embodiments, the first heat exchanger 133 is an evaporator, and the second heat exchanger 134 is a condenser. The dehumidifier 130 also includes a compressor 135 and an expansion valve 136. The refrigerant circulates between the compressor 135, the second heat exchanger 134, the expansion valve 136, and the first heat exchanger 133. Specifically, the compressor 135 compresses the refrigerant into a high-temperature, high-pressure gas, which is then sent to the second heat exchanger 134 (condenser) to dissipate heat and become liquid. This process releases heat, which is exchanged with the air passing through the second heat exchanger, raising the air temperature. Then, the liquid refrigerant is depressurized through the expansion valve 136 into a low-temperature, low-pressure wet vapor, which enters the first heat exchanger 133 (evaporator) to absorb heat from the air passing through it, causing the water vapor in the air to condense into condensate. In other words, the dehumidifier 130 in this embodiment utilizes a heat pump system to cool and heat the gas to be treated, thereby reducing energy consumption.

[0049] In some embodiments, the temperature of the air after heat exchange and cooling with the first heat exchanger 133 is 20°C-30°C. Therefore, by setting the temperature of the air after heat exchange and cooling with the first heat exchanger 133 to 20°C-30°C, the condensation effect of water vapor can be improved, thereby enhancing the dehumidification effect.

[0050] In some embodiments, the temperature of the air after heat exchange with the second heat exchanger 134 is 60°C-75°C. Therefore, by maintaining the temperature of the air after heat exchange with the second heat exchanger 134 at 60°C-75°C, the air can return to the tank 121, maintaining the temperature required for fermentation within the tank 121, thereby improving the fermentation effect.

[0051] In some embodiments, the temperature of the air entering through the air inlet 131 is 40°C-50°C. Therefore, the temperature of the air entering through the air inlet 131 is 40°C-50°C, which means the temperature of the air inside the tank 121 is 40°C-50°C. This allows the temperature inside the tank 121 to be maintained as required for fermentation, thereby improving the fermentation effect. Furthermore, since the air temperature entering through the air inlet 131 is 40°C-50°C, the temperature of the air after heat exchange and cooling with the first heat exchanger 133 is 20°C-30°C. This ensures that the air receives sufficient cooling during heat exchange with the first heat exchanger 133, thereby improving the condensation effect of water vapor and enhancing the dehumidification effect of the air.

[0052] In some embodiments, a humidity sensor and a temperature sensor are also installed inside the fermentation tank 120 to detect the humidity and temperature inside the fermentation tank 120, respectively, to monitor the environment inside the fermentation tank 120. The humidity sensor and the temperature sensor are electrically connected to the dehumidifier 130. The dehumidifier 130 operates based on the humidity and temperature data detected by the humidity sensor and the temperature sensor, adjusting the humidity and temperature inside the fermentation tank 120 to efficiently improve the internal environment of the fermentation tank 120, ensuring that the fermentation tank 120 is at a suitable humidity and temperature for fermentation, and guaranteeing the dryness of the material and the sterilization effect.

[0053] In some embodiments, an air valve is provided on the pipe connecting the air outlet 132 and / or air inlet 131 to the fermentation tank 120. Therefore, when the dehumidifier 130 adjusts the temperature and humidity inside the fermentation tank 120, the air valve can be opened to connect the dehumidifier 130 to the fermentation tank 120, thus allowing for temperature and humidity adjustment within the fermentation tank 120. When the temperature and humidity inside the fermentation tank 120 are within the suitable range for fermentation, and adjustment by the dehumidifier 130 is not required, the air valve can be closed to isolate the fermentation tank 120 from the dehumidifier 130, preventing mutual interference.

[0054] The above description provides an exemplary description of possible embodiments of the fermentation apparatus 100. Below, with reference to the accompanying drawings, an exemplary description of possible embodiments of the fermentation apparatus 10 in this application will be provided.

[0055] like Figure 1 , Figure 2 As shown, this application provides a fermentation device 10, including a fermentation apparatus 100 and a separator 200. The fermentation apparatus 100 can be any of the possible implementations of the aforementioned fermentation apparatus 100; the specific structure of the fermentation apparatus 100 will not be described in detail here. The separator 200 is used to dehydrate the material and transport the dehydrated material to the tank 121 of the fermentation apparatus 100.

[0056] like Figure 1 , Figure 2 As shown, in some embodiments, multiple separators 200 are provided. Therefore, by providing multiple separators 200, the speed of dehydration of the material can be increased, thereby increasing the speed at which the material is supplied to the fermenter 120.

[0057] like Figure 1 , Figure 2As shown, in some embodiments, the fermentation device 10 further includes a conveyor belt 400, which is used to transport the fermented material from the fermentation device 100 to the storage area. Therefore, by using the conveyor belt 400 to transport the fermented material from the fermentation device 100 to the storage area, the accumulation of fermented material at the outlet of the fermentation device 100 can be avoided, thus preventing the normal operation of the fermentation device 100 from being affected.

[0058] The above description provides an exemplary account of possible embodiments of the fermentation apparatus 100 and fermentation equipment 10 in this application. Below, with reference to the accompanying drawings, a detailed description of the specific structure of the fermentation equipment 10 in this application will be provided in specific embodiments.

[0059] Figure 1 This is a schematic diagram of the front orthographic projection of the fermentation equipment 10 in this application; Figure 2 for Figure 1 A schematic diagram of the top orthographic projection structure of the fermentation equipment 10. (See attached diagram.) Figure 1 , Figure 2 As shown, the fermentation equipment 10 includes a fermentation unit 100, a separator 200, a feeding auger 300, and a conveyor belt 400. The separator 200 is used for solid-liquid separation of materials such as manure. After solid-liquid separation, the material is conveyed to the fermentation unit 100 for fermentation. After fermentation, the material is discharged from the fermentation unit 100 and transported by the conveyor belt 400 to the storage area for storage.

[0060] like Figure 1 , Figure 2 As shown, two separators 200 are provided, and both separators 200 are connected to the feed auger 300. After the separators 200 complete the solid-liquid separation of the material, they will convey the material to the feed auger 300. The feed auger 300 is connected to the tank 121 of the fermentation device 100. The feed auger 300 can convey the material obtained by the separators 200 to the fermentation device 100 for fermentation.

[0061] like Figure 1 , Figure 2 As shown, the fermentation apparatus 100 includes a frame 110, a fermentation tank 120, and a dehumidifier 130. The fermentation tank 120 and the dehumidifier 130 are mounted on the frame 110. The fermentation tank 120 is used for fermenting materials. The dehumidifier 130 is connected to the fermentation tank 120 and is used to dehumidify the air inside the fermentation tank 120 to facilitate better fermentation of the materials within the fermentation tank 120.

[0062] like Figure 1 , Figure 2As shown, the fermenter 120 includes a tank body 121, a first end cap 122, and a second end cap 123. The tank body 121 is a cylindrical component with its axis horizontally positioned and horizontally mounted on the frame 110. Specifically, two support portions 126 are provided on the outer circumferential surface of the tank body 121, located at approximately one-quarter of the axial length of the tank body 121 near both ends. The support portions 126 are annular, fitted onto the outer circumferential surface of the tank body 121, and have two annular end faces and a circular outer circumferential surface. The axis of the support portion 126 coincides with the axis of the tank body 121, allowing both the support portion 126 and the tank body 121 to rotate around the same axis.

[0063] like Figure 1 As shown, the frame 110 is equipped with support wheels 111, arranged in pairs, with two pairs of wheels each positioned at the bottom of a support portion 126. The pairs of support wheels 111 are located at the lower part of the support portion 126, on the same radial plane as the tank body 121. The outer circumferential surface of the support wheel 111 abuts against the outer circumferential surface of the support portion 126, allowing the support wheel 111 to support the tank body 121 while simultaneously enabling the tank body 121 to rotate around its axis on the support wheel 111.

[0064] like Figure 1 As shown, the frame 110 is also equipped with limit wheels 112. The limit wheels 112 are arranged in pairs, each located at a corresponding position on one end face of a support part 126, and abut against the two end faces of the support part 126, clamping the support part 126 in the middle and preventing the support part 126 and the tank 121 from moving along the axial direction. Therefore, when the tank 121 rotates on the support wheels 111, it is prevented from shifting, thereby improving the stability of the tank 121's rotation.

[0065] like Figure 1 , Figure 2 As shown, a gear portion 127 is also fitted onto the outer circumferential surface of the tank body 121, with the axis of the gear portion 127 coinciding with the axis of the tank body 121. A motor is also mounted on the frame 110, and the motor is geared to the gear portion 127, thereby driving the gear portion 127 and the tank body 121 to rotate. The gear portion 127 is positioned near another support portion 126 (the support portion 126 without a corresponding limit wheel 112), which reduces the torque between the gear portion 127 and the support portion 126, thereby improving the stability of the tank body 121 rotating on the support wheel 111 when driven by the motor through the gear portion 127.

[0066] like Figure 1As shown, a first end cover 122 and a second end cover 123 are mounted on the frame 110. The first end cover 122 is located at the end of the fermenter 120 facing the conveyor belt 400, and is sealed to the end opening of the tank body 121, allowing the tank body 121 to rotate relative to the first end cover 122. The second end cover 123 is located at the end of the tank body 121 facing the separator 200, and is sealed to the end opening of the tank body 121, allowing the tank body 121 to rotate relative to the second end cover 123. In order to maintain a seal between the two ends of the tank 121 and the first end cap 122 and the second end cap 123 while the tank 121 is rotating, the first end cap 122 and the second end cap 123 can be mounted on the frame 110 by means of springs. The elastic force provided by the springs drives the first end cap 122 and the second end cap 123 to move toward the tank 121, so that the first end cap 122 and the second end cap 123 are always in contact with the two ends of the tank 121 when the tank 121 is rotating, thereby achieving a seal at the two ends of the tank 121.

[0067] The second end cover 123 is provided with a feed inlet 124, and the feed auger 300 is connected to the feed inlet 124. The feed auger 300 can transport the material obtained by the separator 200 into the fermentation tank 120 through the feed inlet 124. The first end cover 122 is provided with a discharge outlet 125. The starting end of the conveyor belt 400 is located below the discharge outlet 125. After fermentation, the material is output from the discharge outlet 125 and can fall directly onto the conveyor belt 400, which will then transport it to the storage area for centralized storage.

[0068] like Figure 1 , Figure 2 As shown, the dehumidifier 130 has an air inlet 131 and an air outlet 132. The air inlet 131 is connected to a pipe to the first end cap 122, allowing air from the fermentation tank 120 to enter the dehumidifier 130 for dehumidification. The air outlet 132 is connected to a pipe to the second end cap 123, allowing the dehumidified air to return to the fermentation tank 120 after being discharged from the dehumidifier 130, thus enabling air circulation between the fermentation tank 120 and the dehumidifier 130.

[0069] like Figure 1 As shown, the air inlet 131 and air outlet 132 are located above the axis of the fermentation tank 120, connecting to the interior of the tank 121. Specifically, they are located above the first end cover 122 and the second end cover 123, in the upper 1 / 3 of the height direction of the first end cover 122 and the second end cover 123. This prevents the material inside the fermentation tank 120 from blocking the air inlet 131 and air outlet 132, thus ensuring the dehumidification effect of the dehumidifier 130 on the air inside the fermentation tank 120 and improving the fermentation effect of the material.

[0070] Figure 3 This is a schematic diagram illustrating the principle of dehumidifier 130 dehumidifying the air inside fermentation tank 120. Figure 3 As shown, the dehumidifier 130 includes a first heat exchanger 133, a second heat exchanger 134, a compressor 135, and an expansion valve 136. The first heat exchanger 133 is an evaporator, and the second heat exchanger 134 is a condenser. Refrigerant circulates between the compressor 135, the second heat exchanger 134, the expansion valve 136, and the first heat exchanger 133. Specifically, the compressor 135 compresses the refrigerant into a high-temperature, high-pressure gas, which is then sent to the second heat exchanger 134 (condenser) to dissipate heat and become liquid. This process releases heat, which is exchanged with the air passing through the second heat exchanger, raising the air temperature. Then, the liquid refrigerant is depressurized through the expansion valve 136, becoming a low-temperature, low-pressure wet vapor, which enters the first heat exchanger 133 (evaporator) to absorb heat from the air passing through it, causing the water vapor in the air to condense into condensate.

[0071] like Figure 3 As shown, the air (high-temperature, humid air, temperature 40℃-50℃) inside the fermentation tank 120 enters the dehumidifier 130 through the air inlet 131 and exchanges heat with the first heat exchanger 133, cooling the air to 20℃-30℃. This causes water vapor in the air to condense into condensate on the first heat exchanger 133. A water collection tray is located below the first heat exchanger 133 to collect the condensate. A drain pipe is installed at the bottom of the water collection tray to discharge the collected condensate to a predetermined location.

[0072] like Figure 3 As shown, the air cooled by heat exchange with the first heat exchanger 133 forms dry and cold air. After passing through the second heat exchanger 134, it is heated to 60℃-75℃ by heat exchange with the second heat exchanger 134. Then it is discharged from the air outlet 132, making the air form high-temperature dry and hot air, which is sent back into the fermentation tank 120. This reduces the humidity of the air in the fermentation tank 120 while maintaining the temperature required for fermentation.

[0073] like Figure 3As shown, the dehumidifier 130 also includes a first energy-saving device 137 and a second energy-saving device 138. The first energy-saving device 137 and the second energy-saving device 138 are connected by a pipe, and a heat exchange medium circulates between them. The first energy-saving device 137 is located in front of the first heat exchanger 133, so that the air (hot and humid air) entering through the air inlet 131 exchanges heat with the first energy-saving device 137 before entering the first heat exchanger 133 for cooling, thereby reducing the workload of the first heat exchanger 133 and thus reducing energy consumption. After the first energy-saving device 137 heats up the air through heat exchange, it transfers the heated heat exchange medium to the second energy-saving device 138. The second energy-saving device 138 is positioned in front of the second heat exchanger 134. This allows the air (dry, cold air) cooled by heat exchange with the first heat exchanger 133 to first exchange heat with the second energy-saving device 138, raising its temperature. The air then exchanges heat with the second heat exchanger 134, further increasing its temperature. This reduces the workload of the second heat exchanger 134 and consequently lowers energy consumption. After the second energy-saving device 138 cools the air, it then supplies the cooled heat exchange medium to the first energy-saving device 137, thus forming a cycle.
