Description

Technical Field

[0001] This disclosure relates to the field of microbial fertilizer manufacturing technology, and in particular to a compound microbial agent production device and its production method. Background Technology

[0002] Compound microbial inoculants are live preparations made from two or more non-antagonistic microbial strains. Through the principles of microecological engineering, multiple non-antagonistic microbial strains are fermented together to create live preparations, exhibiting rational strain compatibility and functional complementarity. In agriculture, the synergistic effect of Bacillus subtilis and other microbial communities can improve nitrogen, phosphorus, and potassium absorption rates, promote root development, increase crop yields by 15-30%, improve soil, and enhance crop disease resistance. As a green and environmentally friendly fertilizer, compound microbial inoculants are increasingly widely used in agricultural production. As an important component of organic fertilizer, microbial inoculants can effectively decompose organic matter, inhibit pathogens, and promote plant growth.

[0003] In the existing technology, the preparation of compound microbial agents involves mixing the bacterial liquid with the fermentation material and then fermenting it. After that, it needs to be dried. However, the conventional fermentation method of piling up the materials affects the efficiency of subsequent drying. Furthermore, after drying, the compound microbial agents need to be pulverized.

[0015] A method for producing a compound microbial agent, the method comprising the following steps: (1) Select three strains of bacteria: Bacillus subtilis, phosphate-solubilizing bacteria and potassium-solubilizing bacteria, and inoculate them into the corresponding liquid culture medium to make three different bacterial suspensions. Then, put them into the bacterial liquid mixing tank and stir them evenly. Mix and crush livestock and poultry manure, crop straw and peat soil. Put the crushed material into the feed mixing tank and stir it evenly to make fermentation substrate. Put the fermentation substrate and bacterial suspension into the mixing tank and stir according to the ratio. (2) The collection tray in the drying box is horizontally fed into the fermentation box from top to bottom by rotating the assembly. The mixture is fed from the mixing box into the collection plate at the bottom of the fermentation box through the conveying channel and the feeding plate, and the mixture is evenly sprinkled. (3) The collection plate containing the mixture is moved upward along the inside of the frame assembly by the lifting component, and the rotating component continues to send the collection plate inside the drying box into the bottom of the fermentation box, and continues to receive the mixture through the collection plate. Multiple sets of collection trays are stacked and stored inside the fermentation box. (4) Sterile and oxygenated air is sent into the fermentation chamber by a blower, and the temperature control system inside the fermentation chamber is controlled to adjust the appropriate fermentation temperature. After fermentation is completed, the collection plate is sent back to the drying chamber from the top of the fermentation chamber. (5) The collection plate stacked inside the drying box is dried by the drying fan at the top of the fermentation box. When the bottom collection plate is sent back into the fermentation box by rotating the assembly, the dried mixture is pushed down to the bottom of the drying box. The mixture is then completely crushed by two crushing shafts and sent out through the delivery channel.

[0016] The technical solution provided in this disclosure may include the following beneficial effects: 1. This invention uses a feed mixing box to mix feed raw materials and a bacterial liquid mixing box to mix bacterial liquid. After being mixed evenly in the mixing box according to the ratio, the mixture is fed into the conveying channel under the control of a solenoid valve. After the collecting plate enters the fermentation box from the bottom of the drying box, the slider and spring telescopic plate are moved horizontally by the screw device in the slide rail. At this time, the feeding plate, which is inclined and inserted into the fermentation box, moves along the top of the collecting plate. The mixture is fed onto the collecting plate by the inclination of the feeding plate and the outlet, and is evenly distributed. With the setting of the moving groove, when the feeding plate moves, the bottom of the conveying channel slides along the moving groove to maintain communication with the feeding plate. 2. In this invention, when the collection plate at the bottom of the drying box moves towards the fermentation box, the feed on the collection plate is pushed out by the scraper and falls between the two crushing shafts through the bottom inclined plate. The first motor drives the two gears to rotate and mesh, so that the two crushing shafts rotate synchronously in opposite directions to crush the dried material and fall down from the delivery channel for collection. The two side plates can prevent the material from falling to the outside. 3. During the fermentation and drying stages, the invention uses a first electric push rod to lower two sealing plates to seal and block the inlet and outlet, isolating the fermentation box and the drying box. When it is necessary to transfer the collection plate, the sealing plates are moved upward to open the inlet and outlet. The second electric push rod drives the scraper to descend. When the collection plate at the bottom of the drying box is moved horizontally back into the fermentation box, the scraper contacts the top of the collection plate, pushing the dried feed on the collection plate out into the lower layer of the drying box. 4. In this invention, the sprocket of the sprocket and chain device is driven by a second motor to rotate. Under the transmission action of the transmission belt and shaft, the sprocket and chain device inside the fermentation box and the drying box can synchronously drive the lifting plate on the chain to move. The lifting plate contacts the convex plates on both sides of the collection plate along the first moving notch, pushing the collection plate in the fermentation box upward along the vertical rail and the collection plate in the drying box downward. The lifting plate on the other side of the chain passes through the second moving notch, which can avoid movement interference. The collection plates stacked inside the fermentation box and the drying box are supported by the vertical columns at the four corners to maintain a certain distance and facilitate the vertical movement of the lifting plate. The air vents on the collection plate can facilitate the air flow during fermentation and drying, thereby improving the fermentation and drying effect. 5. In this invention, the extended end of a third electric push rod is inserted into the extended end of a bidirectional telescopic plate. The third motor drives the bidirectional telescopic plate to rotate, simultaneously pulling two sets of inserts horizontally. After the two inlets and outlets on the middle plate are opened, the inserts on the outside of the fermentation box drive the push plate to move, causing the top collection plate of the fermentation box to slide along the horizontal rail, pass through the top inlet and outlet, and enter the horizontal rail of the drying box. The inserts at the bottom of the drying box push the bottom collection plate along the horizontal rail, pass through the lower inlet and outlet of the middle plate, and enter the fermentation box. This completes the cyclical conversion of the collection plates inside the fermentation box and the drying box, enabling the fermented feed to enter the drying box for drying. After drying, the feed can be sent out and returned to the fermentation box for continued use. It also facilitates the sending out of the dried collection plate.

[0019] Embodiments of this disclosure are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are used only to explain this disclosure, and should not be construed as limiting this disclosure. Rather, embodiments of this disclosure include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0020] like Figure 1 As shown, a method for producing a compound microbial agent includes the following steps: (1) Select three strains of bacteria: Bacillus subtilis, phosphate-solubilizing bacteria and potassium-solubilizing bacteria, and inoculate them into the corresponding liquid culture medium to make three different bacterial suspensions. Then, put them into the bacterial liquid mixing tank and stir them evenly. Mix and crush livestock and poultry manure, crop straw and peat soil. Put the crushed material into the feed mixing tank and stir it evenly to make fermentation substrate. Put the fermentation substrate and bacterial suspension into the mixing tank and stir according to the ratio. (2) The collection tray in the drying box is horizontally fed into the fermentation box from top to bottom by rotating the assembly. The mixture is fed from the mixing box into the collection plate at the bottom of the fermentation box through the conveying channel and the feeding plate, and the mixture is evenly sprinkled. (3) The collection plate containing the mixture is moved upward along the inside of the frame assembly by the lifting component, and the rotating component continues to send the collection plate inside the drying box into the bottom of the fermentation box, and continues to receive the mixture through the collection plate. Multiple sets of collection trays are stacked and stored inside the fermentation box. (4) Sterile and oxygenated air is sent into the fermentation chamber by a blower, and the temperature control system inside the fermentation chamber is controlled to adjust the appropriate fermentation temperature. After fermentation is completed, the collection plate is sent back to the drying chamber from the top of the fermentation chamber. (5) The collection plate stacked inside the drying box is dried by the drying fan at the top of the fermentation box. When the bottom collection plate is sent back into the fermentation box by rotating the assembly, the dried mixture is pushed down to the bottom of the drying box. The mixture is then completely crushed by two crushing shafts and sent out through the delivery channel.

[0021] like Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 7 and Figure 8As shown in the present disclosure, an embodiment of a compound microbial agent production device is proposed, comprising: a fermentation chamber 1, a middle plate 19 fixed on one side of the fermentation chamber 1, and a drying chamber 2 fixed on the other side of the middle plate 19; a frame assembly 5 is provided inside both the fermentation chamber 1 and the drying chamber 2; lifting assemblies 3 are provided on both sides of the fermentation chamber 1 and the drying chamber 2; and a rotating assembly 4 is provided on one side of the middle plate 19; the frame assembly 5 includes vertical rails 51, two sets of which are fixed to the inner walls of the fermentation chamber 1 and the drying chamber 2; horizontal rails 53 are fixed to the top and bottom of the vertical rails 51, and both ends of the vertical rails 51 are connected to the horizontal rails 53; the drying chamber 2 and the fermentation chamber 1... The horizontal rails 53 are on the same straight line. Multiple sets of collecting plates 58 are equidistantly arranged inside the fermentation chamber 1 and the drying chamber 2. Convex plates 511 are fixed to both sides of each collecting plate 58, and the convex plates 511 slide along the vertical rails 51 and the horizontal rails 53. The lifting assembly 3 includes a vertical frame 31. Vertical frames 31 are fixed to both sides of the drying chamber 2 and the fermentation chamber 1, and a sprocket and chain device 34 is rotatably installed inside the vertical frame 31. Lifting plates 57 are equidistantly fixed to the chain surface of the sprocket and chain device 34, and the lifting plates 57 are in contact with the bottom of the convex plates 511. The rotating assembly 4 includes a bracket 43. Two sets of brackets 43 are provided, and the two sets of brackets 43 are respectively inserted into the fermentation chamber 1 and the drying chamber 2 away from the center. On the top and bottom of one side of plate 19, the selection of bacterial solution in this scheme can be based on different raw materials, such as disinfectants, insecticides or herbicides; preparation of insect repellents or attractants, soil conditioners. When using the device, three bacterial strains, Bacillus subtilis, phosphate-solubilizing bacteria and potassium-solubilizing bacteria, are selected and inoculated into the corresponding liquid culture medium to prepare three different bacterial suspensions, which are then sent into the bacterial solution mixing tank 12 and stirred evenly. Livestock and poultry manure, crop straw and peat are mixed and crushed, and the crushed material is sent into the feed mixing tank 11 and stirred evenly to prepare fermentation substrate. According to the ratio, the fermentation substrate and bacterial suspension are sent into the mixing tank 13 and stirred. The collection tray in the drying box 2 is moved from top to bottom by rotating component 4. The mixture is fed into the fermentation chamber 1 from the mixing chamber 13 through the conveying channel 14 and the feeding plate 15, and the mixture is evenly sprinkled. The lifting component 3 moves the collection plate 58 loaded with the mixture upward along the inside of the frame component 5. The rotating component 4 continues to send the collection plate 58 inside the drying chamber 2 into the bottom of the fermentation chamber 1, and continues to receive the mixture through the collection plate 58. Multiple sets of collection trays are stacked and stored inside the fermentation chamber 1. When the rotating component 4 sends the bottom collection plate 58 back into the fermentation chamber 1, the dried mixture is pushed down to the bottom of the drying chamber 2. The mixture is then thoroughly crushed by the two crushing shafts 26 and sent out through the delivery channel 27.

[0022] like Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, in some embodiments, a feed mixing tank 11 is fixed to the top of the fermentation tank 1, and an addition port is provided on the top of the feed mixing tank 11. A bacterial liquid mixing tank 12 is fixed to the top of the fermentation tank 1 on one side of the feed mixing tank 11, and an inlet pipe is provided on the top of the bacterial liquid mixing tank 12. A mixing tank 13 is fixed to the bottom of the fermentation tank 1 at the bottom of the feed mixing tank 11 and the bacterial liquid mixing tank 12. The bottoms of the feed mixing tank 11 and the bacterial liquid mixing tank 12 are connected to the mixing tank 13 through pipes. Each of the feed mixing tank 11, the bacterial liquid mixing tank 12, and the mixing tank 13 has a stirring frame installed inside via a motor. The surface of the fermentation tank 1 on one side of the mixing tank 13 corresponds to the lower horizontal rail 53. The position is fixed with slide rails 46, and sliders 45 are slidably installed inside the two sets of slide rails 46 through a screw device. Spring telescopic plates 47 are fixed on the outside of the sliders 45. Feeding plates 15 are fixed to the extended ends of the two spring telescopic plates 47. The feeding plates 15 are inclined and slide through the top of the bottom collection plate 58 inside the fermentation box 1. The insertion end of the feeding plates 15 has a feeding outlet 17, and the top of the feeding plates 15 has a moving groove 18. The fermentation box 1 has a conveying channel 14 fixed on the outer wall of the top of the feeding plates 15, and the bottom of the conveying channel 14 is slidably installed inside the moving groove 18. The bottom of the mixing box 13 is fixedly connected to the conveying channel 14 through a pipe.

[0023] It is understandable that the feed raw materials are mixed by the feed mixing tank 11, the bacterial liquid is mixed by the bacterial liquid mixing tank 12, and then fed into the mixing tank 13 according to the ratio and mixed evenly. After being fed into the conveying channel 14 by the control of the solenoid valve, the collecting plate 58 enters the fermentation tank 1 from the bottom of the drying box 2. The slider 45 and the spring telescopic plate 47 are moved horizontally by the screw device in the slide rail 46. At this time, the feeding plate 15, which is inserted into the fermentation tank 1 at an inclination, moves along the top of the collecting plate 58. The mixed material is fed into the collecting plate 58 by the inclination of the feeding plate 15 and the discharge outlet 17 and is evenly distributed. With the setting of the moving groove 18, when the feeding plate 15 moves, the bottom of the conveying channel 14 slides along the moving groove 18 to maintain communication with the feeding plate 15. The feed mixing tank 11, bacterial liquid mixing tank 12 and mixing tank in this solution are based on the same principle as the mixing equipment used in the manufacture of organic fertilizer and microbial fertilizer.

[0024] like Figure 5 and Figure 7As shown, in some embodiments, a blower 16 is fixed to the bottom of the fermentation chamber 1 at the frame assembly 5, and an air inlet communicating with the blower 16 is opened on the outside of the fermentation chamber 1. A drying fan 21 is fixed to the top of the drying chamber 2, and an air outlet communicating with the drying fan 21 is opened on the top of the drying chamber 2. An air inlet pipe is provided on the outside of the drying chamber 2. Two pulverizing shafts 26 are symmetrically and rotatably mounted at the bottom of the drying chamber 2 at the bottom of the frame assembly 5, and side plates are fixed to the bottom of the drying chamber 2 on both sides of the pulverizing shafts 26. 24, and an inclined plate 25 is fixed on the top of the side plate 24 facing the crushing shaft 26. The other end of the inclined plate 25 slides in contact with the top of the crushing shaft 26. Gears 23 are rotatably installed on the outside of the drying chamber 2 corresponding to the positions of the two crushing shafts 26. The two gears 23 are meshed and connected. A first motor 22 is fixed on the drying chamber 2 corresponding to the position of the gear 23 on one side, and the output end of the first motor 22 is fixedly connected to the gear 23. The bottom of the drying chamber 2 is located between the two crushing shafts 26 and a feeding channel 27 is fixedly provided.

[0025] It is understandable that sterile, aerobic air is delivered into the fermentation chamber 1 by the blower 16 for aerobic fermentation. At the same time, the fermentation chamber 1 is equipped with a temperature control system to regulate the temperature inside the fermentation chamber 1 to achieve a suitable fermentation environment. The drying blower 21 blows air to dry the collection plates 58 stacked inside the drying chamber 2. When the bottom collection plate 58 of the drying chamber 2 moves towards the fermentation chamber 1, the scraper 114 pushes the feed on the collection plate 58 out and it falls between the two crushing shafts 26 through the bottom inclined plate 25. The first motor 22 drives the two gears 23 to rotate and mesh, so that the two crushing shafts 26 rotate synchronously in opposite directions to crush the dried material. The material falls and is collected from the discharge channel 27. The two side plates 24 can prevent the material from falling to the outside.

[0026] like Figure 8 and Figure 9 As shown, in some embodiments, the intermediate plate 19 has inlet and outlet 112 at the positions of the upper and lower sets of horizontal rails 53 corresponding to the fermentation box 1 and the drying box 2, and a sealing plate 113 is slidably inserted into the top of the inlet and outlet 112. The two sealing plates 113 are fixedly connected. The top of the intermediate plate 19 is symmetrically fixed with a first electric push rod 110, and the extended end of the first electric push rod 110 is fixedly connected to the sealing plate 113. The inlet and outlet 112 at the lower end of the intermediate plate 19 is provided with a scraper 114 on one side of the baffle 55, and the scraper 114 slides along the inside of the intermediate plate 19. The top of the intermediate plate 19 is fixed with two sets of second electric push rods 111 at the positions corresponding to the scraper 114, and the extended end of the second electric push rod 111 is fixedly connected to the scraper 114.

[0027] It should be noted that during the fermentation and drying stages, the first electric push rod 110 drives the two sealing plates 113 to descend and seal the inlet and outlet 112, thus isolating the fermentation chamber 1 and the drying chamber 2. When it is necessary to transfer the collection plate 58, the sealing plate 113 is moved upward to open the inlet and outlet 112. The second electric push rod 111 drives the scraper 114 to descend. When the collection plate 58 at the bottom of the drying chamber 2 is moved horizontally back into the fermentation chamber 1, the scraper 114 contacts the top of the collection plate 58, pushing the dried feed on the collection plate 58 out and into the lower layer of the drying chamber 2.

[0028] like Figure 6 , Figure 8 , Figure 10 , Figure 11 and Figure 12 As shown, in some embodiments, the lifting assembly 3 further includes: a second motor 32 and a transmission belt 33. The second motor 32 is fixed to the bottom of the vertical frame 31 on one side of the drying chamber 2, and the output end of the second motor 32 is fixedly connected to the sprocket of the sprocket and chain device 34. The transmission belt 33 is installed on the top of the vertical frame 31 on the same side of the fermentation chamber 1 and the drying chamber 2, and the pulley of the transmission belt 33 is fixedly connected to the sprocket of the sprocket and chain device 34 inside the vertical frame 31. The sprocket at the top of the fermentation chamber 1 is fixedly connected by a shaft. The vertical rail 51 and the horizontal rail 53 have a first moving notch 52 corresponding to the moving path of the lifting plate 57 on one side of the chain, and the horizontal rail 53 has a second moving notch 54 corresponding to the moving path of the lifting plate 57 on the other side of the chain. The lifting plate 57 moves along the first moving notch 52 and the second moving notch 54. The frame assembly 5 also includes: a baffle 55, a pusher block 56, a pusher plate 35, and a vertical column 510. The vertical column 510 is fixed at the four corners of the top of the collecting plate 58. The bottom of the collecting plate 58 is pressed against the lower vertical column 510. The inner wall of the fermentation box 1 and the drying box 2 on the side away from the middle plate 19 is fixed with a baffle 55 corresponding to the position of each collecting plate 58. The uppermost baffle 55 of the fermentation box 1 is provided with a pusher plate 35 on the outside. The bottommost baffle 55 of the drying box 2 is provided with pushers 56 on both sides. The two inserts 43 are fixedly connected to the pusher plate 35 and the pusher block 56 respectively. The collecting plate 58 has multiple air windows 59 on its surface.

[0029] It should be noted that the second motor 32 drives the sprocket of the sprocket and chain device 34 to rotate. Under the transmission action of the transmission belt 33 and the shaft, the sprocket and chain device 34 inside the fermentation box 1 and the drying box 2 can synchronously drive the lifting plate 57 on the chain to move. The lifting plate 57 contacts the protruding plates 511 on both sides of the collecting plate 58 along the first moving notch 52, pushing the collecting plate 58 in the fermentation box 1 upward along the vertical rail 51, and the collecting plate 58 in the drying box 2 moves downward. The lifting plate 57 on the other side of the chain passes through the second moving notch 54, which can avoid movement interference. The collecting plates 58 stacked inside the fermentation box 1 and the drying box 2 are supported by the vertical columns 510 at the four corners to maintain a certain distance and facilitate the vertical movement of the lifting plate 57. The air window 59 on the collecting plate 58 can facilitate the air flow during fermentation and drying, thereby improving the fermentation and drying effect.

[0030] like Figure 3 , Figure 5 , Figure 6 , Figure 7 , Figure 9 and Figure 10 As shown, in some embodiments, the rotating assembly 4 further includes: a third motor 41, a bidirectional telescopic plate 42, and a third electric push rod 44. The bidirectional telescopic plate 42 is rotatably mounted at the middle position of the intermediate plate 19. The two inserts 43 are fixed with the third electric push rod 44 on one side facing the extended end of the bidirectional telescopic plate 42, and the extended end of the third electric push rod 44 is slidably inserted into the extended end of the bidirectional telescopic plate 42.

[0031] It should be noted that the third electric push rod 44 is inserted into the extended end of the bidirectional telescopic plate 42. The third motor 41 drives the bidirectional telescopic plate 42 to rotate, and at the same time pulls the two sets of inserts 43 to move horizontally. After the two inlets and outlets 112 of the middle plate 19 are opened, the inserts 43 on the outside of the fermentation box 1 drive the push plate 35 to move, and slide the top collection plate 58 of the fermentation box 1 along the horizontal rail 53, through the top inlet and outlet 112 and into the horizontal rail 53 of the drying box 2. The inserts 43 at the bottom of the drying box 2 push the bottom collection plate 58 along the horizontal rail 53 through the bottom inlet and outlet 112 of the middle plate 19 through the push block 56 and into the fermentation box 1. This completes the cycle of the collection plates 58 in the fermentation box 1 and the drying box 2, so that the fermented feed can enter the drying box 2 for drying. After drying, the feed can be sent out and returned to the fermentation box 1 for continued use. It is also convenient to send out the feed on the dried collection plate 58.

[0032] Working principle: When using the device, three bacterial strains—Bacillus subtilis, phosphate-solubilizing bacteria, and potassium-solubilizing bacteria—are selected and inoculated into their respective liquid culture media to prepare three different bacterial suspensions. These suspensions are then fed into the bacterial suspension mixing tank 12 and stirred evenly. Livestock and poultry manure, crop straw, and peat moss are mixed and pulverized, and the pulverized material is fed into the feed mixing tank 11 and stirred evenly to prepare the fermentation substrate. The fermentation substrate and bacterial suspension are then fed into the mixing tank 13 according to the specified ratio and stirred. Sterile aerobic air is then introduced into the fermentation tank 1 by the blower 16 for aerobic fermentation. The fermentation tank 1 is equipped with a temperature control system to regulate the temperature and achieve a suitable fermentation environment. The drying fan 21 blows air onto the stacked collection plates 58 inside the drying tank 2 for drying. The bottom of the drying tank 2 collects the air. When the collecting plate 58 moves towards the fermentation chamber 1, the scraper 114 pushes the feed off the collecting plate 58, which then falls between the two crushing shafts 26 via the bottom inclined plate 25. The first motor 22 drives the two gears 23 to rotate and mesh, causing the two crushing shafts 26 to rotate synchronously in opposite directions, crushing the dried material. The material then falls through the discharge channel 27 for collection. Two side plates 24 prevent the material from falling to the outside. During the fermentation and drying stages, the first electric push rod 110 drives the two sealing plates 113 to descend and seal the inlet and outlet 112, isolating the fermentation chamber 1 and the drying chamber 2. When it is necessary to move the collecting plate 58, the sealing plates 113 are moved upward to open the inlet and outlet 112, and the second electric push rod 111 drives the scraper 114 to descend at the bottom of the drying chamber 2. When the collecting plate 58 moves horizontally back into the fermentation chamber 1, the scraper 114 contacts the top of the collecting plate 58, pushing the dried feed on the collecting plate 58 into the lower layer of the drying chamber 2. The second motor 32 drives the sprocket of the sprocket chain device 34 to rotate. Under the transmission action of the transmission belt 33 and the shaft, the sprocket chain device 34 inside the fermentation chamber 1 and the drying chamber 2 can synchronously drive the lifting plate 57 on the chain to move. The lifting plate 57 contacts the protruding plates 511 on both sides of the collecting plate 58 along the first moving notch 52, pushing the collecting plate 58 in the fermentation chamber 1 upward along the vertical rail 51, and the collecting plate 58 in the drying chamber 2 downward. The lifting plate 57 on the other side of the chain passes through the second moving notch 54, avoiding movement interference. The collection plates 58 stacked inside the drying chamber 2 are supported by vertical columns 510 at the four corners, maintaining a certain distance and facilitating vertical movement of the lifting plate 57. Air vents 59 on the collection plates 58 allow for airflow during fermentation and drying, improving the efficiency of both processes. A third electric push rod 44, with its extended end inserted into the extended end of the bidirectional telescopic plate 42, is driven to rotate by a third motor 41. Simultaneously, the two sets of inserts 43 move horizontally. After the two inlets / outlets 112 on the middle plate 19 are opened, the inserts 43 on the outside of the fermentation chamber 1 move the push plate 35, sliding the top collection plate 58 of the fermentation chamber 1 along the horizontal rail 53, passing through the top inlet / outlet 112, and into the horizontal rail 53 of the drying chamber 2.The insert rack 43 at the bottom of the drying chamber 2 pushes the lowest collecting plate 58 along the horizontal rail 53 through the lower inlet / outlet 112 of the middle plate 19 into the fermentation chamber 1 via the push block 56. This completes the circulation of the collecting plate 58 between the fermentation chamber 1 and the drying chamber 2, allowing the fermented feed to enter the drying chamber 2 for drying. After drying, the feed can be returned to the fermentation chamber 1 for continued use, and it also facilitates the removal of the dried feed from the collecting plate 58.
