Description

Technical Field

[0001] This invention relates to the field of microbial agent preparation technology, specifically to an apparatus and process for preparing a compound microbial agent for white-skinned chicken bamboo. Background Technology

[0002] Bai Bu Ji Bamboo Compound Microbial Agent is a compound microbial agent prepared from bamboo leaves, branches, and shavings of Bai Bu Ji Bamboo through processes such as strain selection, raw material pretreatment, fermentation, mixing, and packaging.

[0003] Patent publication number CN214528979U relates to a device for preparing a lactic acid bacteria compound inoculant. The device includes a housing with a first chamber and a second chamber inside. A rotary motor is embedded in each of the first and second chambers. A rotating shaft is fixedly connected to the output shaft of the rotary motor, and a bearing is fitted to one end of the rotating shaft. The bearing is fixedly connected to the inner walls of both the first and second chambers. A stirring paddle is fixedly connected to the surface of the rotating shaft. The advantages are that by using two rotary motors in the first and second chambers respectively, the raw materials inside can be stirred, facilitating better fermentation later. A first feed pump and a first pipeline can transport the steam-sterilized raw materials from the first chamber to the second chamber, facilitating fermentation in the second chamber and also enabling material transfer.

[0004] In the aforementioned patent, two rotary motors are installed in the first and second chambers respectively to stir the raw materials inside the first and second chambers, which facilitates better fermentation of the raw materials in the later stage. The first feed pump and the first pipeline can transfer the steam-sterilized raw materials from the first chamber to the second chamber, which facilitates fermentation of the materials in the second chamber and also realizes the transfer of materials. However, the continuous spraying of compound bacteria during the fermentation process may lead to high water content, which may block the pores of the substrate, reduce air permeability, prevent oxygen from effectively penetrating the tank, inhibit the respiration and metabolism of aerobic bacteria, and at the same time, cause a large number of anaerobic bacteria to grow, resulting in mold and odor of the fermentation material. In addition, the continuous introduction of oxygen will lead to insufficient moisture, which will cause the bacterial cells to dehydrate, significantly reduce metabolic activity, slow down the proliferation rate, and fail to form a sufficient concentration of active bacteria. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a preparation apparatus and process for a compound microbial agent for white-breasted chicken bamboo, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a device for preparing a compound microbial agent for *Bambusa textilis*, comprising: a fermentation tank; a feed inlet located at the top of the fermentation tank; a motor fixedly mounted on the surface of the fermentation tank; a stirring rod located at the output end of the motor; a mounting frame fixedly mounted on the surface of the fermentation tank; a ventilation device located at the top of the mounting frame; and a connecting pipe, one end of which is fixedly mounted at the bottom of the ventilation device, and the other end of which is fixedly mounted on the surface of the fermentation tank; the top of the fermentation tank... The fermentation tank is equipped with a bacterial culture tank. A linear motor is installed on the top of the inner wall of the fermentation tank. A scraper is installed at the output end of the linear motor. A pulley frame is fixedly installed on the surface of the scraper. An outlet pipe is installed at the bottom of the bacterial culture tank. A sliding rod is slidably installed on the surface of the outlet pipe. A sealing plate is fixedly installed on the top of the sliding rod. A connecting plate is fixedly installed on the bottom of the sliding rod. A trapezoidal block is fixedly installed on the surface of the connecting plate. When the trapezoidal block moves upward, it will drive the connecting plate, the sliding rod, and the sealing plate to move upward. When the sealing plate moves upward, it will disengage from the seal on the outlet pipe, allowing the bacterial culture liquid inside the bacterial culture tank to flow into the fermentation tank, thereby improving fermentation efficiency.

[0007] According to the above technical solution, a sliding frame is slidably installed on the surface of the connecting plate, a rotating plate is rotatably installed on the inner wall of the connecting plate, a baffle is fixedly installed at the bottom of the rotating plate, a short plate is fixedly installed on the surface of the rotating plate, an exhaust box is provided at the top of the fermentation tank, an air intake pipe is provided at the bottom of the exhaust box, and a gas separation membrane is provided on the inner wall of the exhaust box. When the connecting plate moves upward, it will drive the sliding frame to move upward. When the sliding frame moves upward, it will contact the liquid outlet pipe. The reverse force will push the sliding frame to move downward. When the sliding frame moves downward, it will push the short plate to rotate downward. When the short plate rotates downward, it will drive the rotating plate and the baffle to rotate upward. A first spring is provided between the liquid outlet pipe and the sliding rod. The first spring's own elastic force will drive the sliding rod to reset. A first torsion spring is provided between the connecting plate and the rotating plate. The first torsion spring's own elastic force will drive the rotating plate to reset.

[0008] A preparation process for a compound microbial agent preparation device for white-skinned chicken bamboo includes the following steps: Step 1: After mixing the crushed white bamboo raw material particles evenly, put them into the fermentation box, then start the motor. The motor stirs at low speed to ensure that the inoculum liquid and the substrate are in full contact, improving the mixing effect. At the same time, start the linear motor, which will drive the scraper to move back and forth on the inner wall of the fermentation box. The reciprocating motion of the scraper prevents the material from sticking to the inner wall of the fermentation box and affecting the subsequent fermentation effect. At the same time, the reciprocating motion of the scraper can also assist in cleaning the fermentation box later, improving the cleaning effect. Step 2: Simultaneously, as the scraper moves, it will drive the pulley frame to move. As the pulley frame moves, it will push the trapezoidal block upward. The upward movement of the trapezoidal block will drive the connecting plate, sliding rod, and sealing plate upward. The upward movement of the sealing plate will disengage from the outlet pipe, allowing the inoculum liquid inside the bacterial liquid tank to flow into the fermentation tank, thus improving fermentation efficiency. Step 3: After the pulley frame disengages from the trapezoidal block, the sealing plate will reseal the outlet pipe to prevent waste caused by continuous spraying of inoculum solution. By intermittently spraying inoculum solution in conjunction with stirring rod, the inoculum solution and material are mixed more thoroughly, avoiding the inoculum solution from concentrating in one place on the material, which would result in the material and inoculum solution not being fully mixed. Step 4: Simultaneously, when the connecting plate moves upward, it will cause the sliding frame to move upward. The upward movement of the sliding frame will contact the liquid outlet pipe, and the reverse force will push the sliding frame downward. The downward movement of the sliding frame will push the short plate to rotate downward. The downward rotation of the short plate will cause the rotating plate and the baffle to rotate upward. The upward rotation of the baffle will block the area below the liquid outlet pipe, allowing the sprayed inoculum liquid to splash onto the surface of the material, increasing the spread range of the inoculum liquid and improving the mixing effect.

[0009] According to the above technical solution, the fermentation box is equipped with a ventilation device and an exhaust device for controlling air intake. The ventilation device includes a rotating shaft, a sealing circular plate, a trapezoidal slider, and a connecting rope. When the pulley frame moves towards the ventilation device, it will contact the trapezoidal slider, which will push the trapezoidal slider upward. The upward movement of the trapezoidal slider will drive the connecting rope upward. The rotating shaft is rotatably installed on the inner wall of the fermentation box, the sealing circular plate is fixedly installed on the surface of the rotating shaft, the trapezoidal slider is slidably installed on the inner wall of the fermentation box, one end of the connecting rope is fixedly installed on the bottom of the trapezoidal slider, and the other end of the connecting rope is fixedly installed on the surface of the sealing circular plate.

[0010] According to the above technical solution, a chute is fixedly installed on the surface of the fermentation box, a slider is slidably installed on the inner wall of the chute, a connecting frame is fixedly installed at the bottom of the slider, a scraper is fixedly installed at the top of the connecting frame, a hinge rod is rotatably installed on the inner wall of the connecting frame, a connecting seat is fixedly installed on the top of the trapezoidal slider, and the end of the hinge rod away from the connecting frame is rotatably installed on the inner wall of the connecting seat. When the connecting frame moves away from the chute, the scraper will move away from the chute.

[0011] According to the above technical solution, a second torsion spring is provided between the rotating shaft and the fermentation box, and the rotating shaft is reset by the elastic force of the second torsion spring itself. A second spring is provided between the trapezoidal slider and the fermentation box, and the trapezoidal slider is reset by the elastic force of the second spring itself. A third spring is provided between the slide groove and the slider, and the slider is reset by the elastic force of the third spring itself.

[0012] According to the above technical solution, the exhaust device includes a connecting rod, a sealing ring, a sliding rod, a trapezoidal frame, and a circular plate. When the trapezoidal slider moves upward, it drives the connecting rod to move upward. The upward movement of the connecting rod pushes the trapezoidal frame towards the air pipe. The movement of the trapezoidal frame towards the air pipe drives the sliding rod and the circular plate towards the air pipe. The movement of the circular plate towards the air pipe disengages the seal on the sealing ring. The connecting rod is fixedly installed on the top of the trapezoidal slider. The exhaust box is connected to the ventilation equipment through an air pipe. A one-way valve is installed inside the air pipe. The sealing ring is fixedly installed on the inner wall of the air pipe. The sliding rod slides through the sealing ring. The trapezoidal frame is fixedly installed on the surface of the sliding rod. The circular plate is fixedly installed at the end of the sliding rod away from the trapezoidal frame.

[0013] According to the above technical solution, a pressure plate is slidably installed on the inner wall of the exhaust box. The pressure plate is fixedly connected to the connecting rod. A long rod slides through the surface of the exhaust box and the pressure plate. A circular plate is fixedly installed on the top of the long rod. When the connecting rod moves upward, it will drive the pressure plate to move upward. The upward movement of the pressure plate will push the circular plate to move upward. The circular plate will seal the circular hole on the surface of the pressure plate.

[0014] According to the above technical solution, a No. 4 spring is provided between the sliding rod and the sealing ring, and the sliding rod is reset by the elastic force of the No. 4 spring itself. A No. 5 spring is provided between the exhaust box and the long rod, and the long rod is reset by the elastic force of the No. 5 spring itself.

[0015] This invention provides an apparatus and process for preparing a compound fungal agent for *Bambusa textilis*. It has the following beneficial effects: (1) This invention prevents materials from sticking to the inner wall of the fermentation tank by the reciprocating motion of the scraper, which affects the subsequent fermentation effect. At the same time, the reciprocating motion of the scraper can assist in the subsequent cleaning of the fermentation tank and improve the cleaning effect. By intermittently spraying the inoculum liquid and stirring with the stirring rod, the inoculum liquid and the materials are mixed more thoroughly, avoiding the inoculum liquid from being concentrated in one place of the materials, which would result in the materials and the inoculum liquid not being fully mixed. This also avoids the waste of resources caused by continuous spraying. At the same time, the downward rotation of the short plate will drive the rotating plate and the baffle to rotate upward. The upward rotation of the baffle will block the bottom of the liquid outlet pipe, so that the sprayed inoculum liquid can splash onto the surface of the materials, increasing the spread range of the inoculum liquid and improving the mixing effect.

[0016] (2) In this invention, rotating the sealing disc upward will open the connecting pipe, allowing the ventilation device to introduce oxygen into the fermentation chamber. When the pulley frame is disengaged from the trapezoidal slider, the elastic force of the second spring will cause the trapezoidal slider to reset. The sealing disc will reset under the elastic force of the second torsion spring after losing the tension of the connecting rope. The reset of the sealing disc will cause the connecting pipe to be resealed, preventing the continuous introduction of oxygen from causing insufficient moisture, dehydration of the bacterial cells, a significant reduction in metabolic activity, a slowdown in proliferation rate, and the inability to form a sufficient concentration of active bacteria. At the same time, the movement of the connecting frame away from the trough will cause the scraper to move away from the trough. The scraper will remove impurities at the bottom of the suction pipe by moving away from the trough, preventing impurities from clogging the suction pipe and affecting the exhaust effect.

[0017] (3) In this invention, a gas containing carbon dioxide and oxygen is drawn into the exhaust box through the suction tube. The carbon dioxide and oxygen are separated by the gas separation membrane. The carbon dioxide will pass through the membrane and enter the upper part of the gas separation membrane. The selective permeability of the gas separation membrane to different gases is used to separate carbon dioxide and oxygen. The oxygen will remain below the gas separation membrane and then re-enter the ventilation equipment through the air tube to realize the oxygen recycling. At the same time, the circular plate moves towards the air tube and will break the seal on the sealing ring, so that the oxygen below the gas separation membrane will re-enter the ventilation equipment to realize the oxygen recycling.

[0018] (4) This invention can provide sufficient separation time for carbon dioxide and oxygen by controlling the movement of the linear motor, preventing oxygen from entering the ventilation equipment along with carbon dioxide and affecting the ventilation effect. When the connecting rod moves upward, it will drive the pressure plate to move upward. The upward movement of the pressure plate will push the circular plate to move upward. The circular plate will seal the circular hole on the surface of the pressure plate. At the same time, the upward movement of the pressure plate will squeeze the oxygen above the pressure plate into the air pipe, improving the recovery and utilization of oxygen and improving the oxygen circulation efficiency.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figure 1 - Figure 7 One embodiment of the present invention is: a preparation device for a compound microbial agent for white-breasted chicken bamboo, comprising: a fermentation tank 1, a feed inlet 2, the feed inlet 2 being disposed at the top of the fermentation tank 1; a motor 3, the motor 3 being fixedly mounted on the surface of the fermentation tank 1; a stirring rod 4, the stirring rod 4 being disposed at the output end of the motor 3; a fixing frame 5, the fixing frame 5 being fixedly mounted on the surface of the fermentation tank 1; a ventilation device 6, the ventilation device 6 being disposed at the top of the fixing frame 5; a connecting pipe 7, one end of the connecting pipe 7 being fixedly mounted at the bottom of the ventilation device 6, and the other end of the connecting pipe 7 being fixedly mounted on the surface of the fermentation tank 1; a microbial liquid tank 8 being disposed at the top of the fermentation tank 1, and a linear motor 9 being disposed at the top of the inner wall of the fermentation tank 1, the output end of the linear motor 9 being disposed at the top of the inner wall of the fermentation tank 1; and a microbial liquid tank 8 being disposed at the top of the fermentation tank 1. A scraper 10 is provided, and a pulley frame 11 is fixedly installed on the surface of the scraper 10. A liquid outlet pipe 12 is provided at the bottom of the liquid tank 8. A sliding rod 13 is slidably installed on the surface of the liquid outlet pipe 12. A sealing plate 14 is fixedly installed on the top of the sliding rod 13. A connecting plate 15 is fixedly installed on the bottom of the sliding rod 13. A trapezoidal block 16 is fixedly installed on the surface of the connecting plate 15. When the pulley frame 11 disengages from the trapezoidal block 16, the sealing plate 14 will re-seal the liquid outlet pipe 12 to prevent waste caused by continuous spraying of the inoculum liquid. By intermittently spraying the inoculum liquid in conjunction with stirring rod 4, the inoculum liquid and the material are mixed more thoroughly, avoiding the inoculum liquid from concentrating in one place on the material, which would result in the material and the inoculum liquid not being fully mixed.

[0023] A sliding frame 171 is slidably mounted on the surface of the connecting plate 15. A rotating plate 172 is rotatably mounted on the inner wall of the connecting plate 15. A baffle 173 is fixedly mounted on the bottom of the rotating plate 172. A short plate 174 is fixedly mounted on the surface of the rotating plate 172. An exhaust box 175 is provided at the top of the fermentation tank 1. An air suction pipe 176 is provided at the bottom of the exhaust box 175. A gas separation membrane 177 is provided on the inner wall of the exhaust box 175. When the baffle 173 rotates upward, it will block the bottom of the liquid outlet pipe 12, so that the sprayed inoculum liquid can splash onto the surface of the material, thereby increasing the spread range of the inoculum liquid and improving the mixing effect. A first spring is provided between the liquid outlet pipe 12 and the sliding rod 13. The sliding rod 13 is reset by the elastic force of the first spring. A first torsion spring is provided between the connecting plate 15 and the rotating plate 172. The rotating plate 172 is reset by the elastic force of the first torsion spring.

[0024] In this embodiment, the following steps are performed: After the pulverized white bamboo raw material granules are evenly mixed, they are placed into the fermentation tank 1. Then, the motor 3 is started, and the motor 3 stirs at low speed to ensure that the inoculum liquid and the substrate are in full contact, improving the mixing effect. At the same time, the linear motor 9 is started, which drives the scraper 10 to reciprocate against the inner wall of the fermentation tank 1. The reciprocating motion of the scraper 10 prevents the material from sticking to the inner wall of the fermentation tank 1, which would affect the subsequent fermentation effect. At the same time, the reciprocating motion of the scraper 10 can assist in the subsequent cleaning of the fermentation tank 1, improving the cleaning effect. During the movement of the scraper 10, the pulley frame 11 is moved, which pushes the trapezoidal block 16 upward. The upward movement of the trapezoidal block 16 drives the connecting plate 15, the sliding rod 13, and the sealing plate 14 upward. The upward movement of the sealing plate 14 will disengage from the seal on the liquid outlet pipe 12, allowing the inoculum liquid inside the inoculum tank 8 to flow into the fermentation tank 1, assisting the fermentation. To improve efficiency, after the pulley frame 11 disengages from the trapezoidal block 16, the sealing plate 14 re-seals the outlet pipe 12 to prevent waste caused by continuous spraying of the inoculum solution. By intermittently spraying the inoculum solution in conjunction with stirring rod 4, the inoculum solution and the material are mixed more thoroughly, preventing the inoculum solution from concentrating in one place and causing the material and inoculum solution to not be fully mixed. At the same time, when the connecting plate 15 moves upward, it will drive the sliding frame 171 to move upward. The upward movement of the sliding frame 171 will contact the outlet pipe 12, and the reverse force will push the sliding frame 171 to move downward. The downward movement of the sliding frame 171 will push the short plate 174 to rotate downward. The downward rotation of the short plate 174 will drive the rotating plate 172 and the baffle 173 to rotate upward. The upward rotation of the baffle 173 will block the bottom of the outlet pipe 12, allowing the sprayed inoculum solution to splash onto the surface of the material, increasing the spread range of the inoculum solution and improving the mixing effect.

[0025] Please see Figure 1 - Figure 7Based on the above embodiments, in another embodiment of the present invention, the fermentation chamber 1 is provided with a ventilation device and an exhaust device for controlling air intake. The ventilation device includes a rotating shaft 181, a sealing circular plate 182, a trapezoidal slider 183, and a connecting rope 184. The rotating shaft 181 is rotatably installed on the inner wall of the fermentation chamber 1, the sealing circular plate 182 is fixedly installed on the surface of the rotating shaft 181, the trapezoidal slider 183 is slidably installed on the inner wall of the fermentation chamber 1, one end of the connecting rope 184 is fixedly installed on the bottom of the trapezoidal slider 183, and the other end of the connecting rope 184 is fixedly installed on the surface of the sealing circular plate 182. The ventilation device 6 introduces oxygen into the fermentation chamber 1. When the sealing circular plate 182 is reset, it will re-seal the connecting pipe 7 to prevent continuous oxygen supply from causing insufficient moisture, dehydration of bacterial cells, significant reduction in metabolic activity, slowing down the proliferation rate, and failure to form a sufficient concentration of active bacteria.

[0026] A chute 185 is fixedly installed on the surface of the fermentation tank 1. A slider 186 is slidably installed on the inner wall of the chute 185. A connecting frame 187 is fixedly installed at the bottom of the slider 186. A scraper 188 is fixedly installed at the top of the connecting frame 187. A hinge rod 189 is rotatably installed on the inner wall of the connecting frame 187. A connecting seat 1810 is fixedly installed on the top of the trapezoidal slider 183. The end of the hinge rod 189 away from the connecting frame 187 is rotatably installed on the inner wall of the connecting seat 1810. By moving the scraper 188 away from the chute 185, impurities at the bottom of the suction pipe 176 are scraped off, preventing impurities from clogging the suction pipe 176 and affecting the exhaust effect.

[0027] A second torsion spring is installed between the rotating shaft 181 and the fermentation box 1. The rotating shaft 181 is reset by the elastic force of the second torsion spring. A second spring is installed between the trapezoidal slider 183 and the fermentation box 1. The trapezoidal slider 183 is reset by the elastic force of the second spring. A third spring is installed between the slide groove 185 and the slider 186. The slider 186 is reset by the elastic force of the third spring.

[0028] In this embodiment, during operation: as the pulley frame 11 moves towards the ventilation device 6, it contacts the trapezoidal slider 183. The pulley frame 11 pushes the trapezoidal slider 183 upward, which in turn moves the connecting rope 184 upward. The upward movement of the connecting rope 184 pulls the rotating plate 172 upward, causing the sealing plate 182 to rotate upward. This upward rotation of the sealing plate 182 opens the connecting pipe 7, allowing oxygen to enter the fermentation chamber 1 through the ventilation device 6. When the pulley frame 11 disengages from the trapezoidal slider 183, the elastic force of the second spring causes the trapezoidal slider 183 to reset. The sealing plate 182, losing the tension of the connecting rope 184, resets under the elastic force of the second torsion spring. The reset of the sealing plate 182 re-seals the connecting pipe 7, preventing continuous oxygen supply. This can lead to insufficient moisture, causing dehydration of the bacterial cells, a significant reduction in metabolic activity, and a slower proliferation rate, making it impossible to form a sufficiently concentrated active bacterial community. At the same time, the upward movement of the trapezoidal slider 183 will cause the connecting seat 1810 to move upward, which in turn will cause the hinge rod 189 to move upward. The upward movement of the hinge rod 189 will cause the connecting frame 187 to move away from the slide 185. The movement of the connecting frame 187 away from the slide 185 will cause the scraper 188 to move away from the slide 185. By moving the scraper 188 away from the slide 185, impurities at the bottom of the suction pipe 176 are scraped away, preventing impurities from clogging the suction pipe 176 and affecting the exhaust effect.

[0029] The exhaust device includes a connecting rod 191, a sealing ring 192, a sliding rod 193, a trapezoidal frame 194, and a circular plate 195. The connecting rod 191 is fixedly installed on the top of the trapezoidal slider 183. The exhaust box 175 is connected to the ventilation device 6 through a gas pipe. A one-way valve is installed inside the gas pipe to restrict gas backflow. The sealing ring 192 is fixedly installed on the inner wall of the gas pipe. The sliding rod 193 slides through the sealing ring 192. The trapezoidal frame 194 is fixedly installed on the surface of the sliding rod 193. The circular plate 195 is fixedly installed at the end of the sliding rod 193 away from the trapezoidal frame 194, so that the oxygen below the gas separation membrane 177 can re-enter the ventilation device 6 to achieve oxygen recycling. At the same time, by controlling the movement of the linear motor 9, sufficient separation time can be given to carbon dioxide and oxygen to prevent oxygen from entering the ventilation device 6 along with carbon dioxide and affecting the ventilation effect.

[0030] A pressure plate 196 is slidably installed on the inner wall of the exhaust box 175. The pressure plate 196 is fixedly connected to the connecting rod 191. A long rod 197 slides through the surface of the exhaust box 175 and the pressure plate 196. A circular plate 198 is fixedly installed on the top of the long rod 197. At the same time, when the pressure plate 196 moves upward, it will squeeze the oxygen above the pressure plate 196 into the trachea, thereby improving the recovery and utilization of oxygen and improving the oxygen circulation efficiency.

[0031] A No. 4 spring is installed between the sliding rod 193 and the sealing ring 192. The sliding rod 193 is reset by the elastic force of the No. 4 spring. A No. 5 spring is installed between the exhaust box 175 and the long rod 197. The long rod 197 is reset by the elastic force of the No. 5 spring.

[0032] A preparation process for a compound microbial agent preparation device for white-skinned chicken bamboo includes the following steps: Step 1: After the crushed white bamboo raw material particles are evenly mixed, they are put into fermentation box 1. Then, motor 3 is started. Motor 3 stirs at low speed to ensure that the inoculum liquid and the substrate are in full contact, thereby improving the mixing effect. At the same time, linear motor 9 is started. Linear motor 9 will drive scraper 10 to move back and forth on the inner wall of fermentation box 1. The reciprocating motion of scraper 10 prevents the material from sticking to the inner wall of fermentation box 1, which would affect the subsequent fermentation effect. At the same time, the reciprocating motion of scraper 10 can also assist in the subsequent cleaning of fermentation box 1, thereby improving the cleaning effect. Step 2: Simultaneously, as the scraper 10 moves, it will drive the pulley frame 11 to move. As the pulley frame 11 moves, it will push the trapezoidal block 16 to move upward. The upward movement of the trapezoidal block 16 will drive the connecting plate 15, the sliding rod 13, and the sealing plate 14 to move upward. The upward movement of the sealing plate 14 will disengage from the seal on the liquid outlet pipe 12, allowing the inoculum liquid inside the bacterial liquid tank 8 to flow into the fermentation tank 1, thereby improving fermentation efficiency. Step 3: After the pulley frame 11 disengages from the trapezoidal block 16, the sealing plate 14 will reseal the liquid outlet pipe 12 to prevent waste caused by continuous spraying of inoculum liquid. By intermittently spraying inoculum liquid in conjunction with stirring rod 4, the inoculum liquid and the material are mixed more thoroughly, avoiding the inoculum liquid from concentrating in one place of the material, which would result in the material and the inoculum liquid not being fully mixed. Step 4: Simultaneously, when the connecting plate 15 moves upward, it will drive the sliding frame 171 to move upward. The upward movement of the sliding frame 171 will contact the liquid outlet pipe 12, and the reverse force will push the sliding frame 171 to move downward. The downward movement of the sliding frame 171 will push the short plate 174 to rotate downward. The downward rotation of the short plate 174 will drive the rotating plate 172 and the baffle 173 to rotate upward. The upward rotation of the baffle 173 will block the area below the liquid outlet pipe 12, allowing the sprayed inoculum liquid to splash onto the surface of the material, increasing the spread range of the inoculum liquid and improving the mixing effect.

[0033] Gas containing carbon dioxide and oxygen is drawn into the exhaust box 175 through the suction pipe 176. The carbon dioxide and oxygen are separated by the gas separation membrane 177. The carbon dioxide passes through the membrane and enters above the gas separation membrane 177. Utilizing the selective permeability of the gas separation membrane 177 to different gases, carbon dioxide and oxygen are separated. The oxygen remains below the gas separation membrane 177 and subsequently re-enters the ventilation device 6 through the air pipe, achieving oxygen recycling. Simultaneously, when the trapezoidal slider 183 moves upward, it drives the connecting rod 191 upward. The upward movement of the connecting rod 191 pushes the trapezoidal frame 194 towards the air pipe. The movement of the trapezoidal frame 194 towards the air pipe causes the sliding rod 193 and the circular plate 195 to move towards the air pipe. When the circular plate 195 moves closer to the trachea, it disengages from the sealing ring 192, allowing oxygen below the gas separation membrane 177 to re-enter the ventilation device 6, thus achieving oxygen recycling. Simultaneously, controlling the linear motor 9 provides sufficient separation time for carbon dioxide and oxygen, preventing oxygen from entering the ventilation device 6 along with carbon dioxide and affecting ventilation efficiency. Furthermore, when the connecting rod 191 moves upward, it drives the pressure plate 196 upward, which in turn pushes the circular plate 198 upward. The circular plate 198 seals the circular holes on the surface of the pressure plate 196, while the upward movement of the pressure plate 196 forces oxygen above it into the trachea, improving oxygen recovery and circulation efficiency.

9. A preparation process for a compound microbial agent preparation device for *Bambusa textilis*, using the compound microbial agent preparation device for *Bambusa textilis* as described in claim 8, characterized in that... Includes the following steps: Step 1: After mixing the crushed white bamboo raw material particles evenly, put them into the fermentation box (1), and then start the motor (3). The motor (3) stirs at low speed to make the inoculum liquid and the substrate fully contact each other and improve the mixing effect. At the same time, start the linear motor (9). The linear motor (9) will drive the scraper (10) to move back and forth on the inner wall of the fermentation box (1). The scraper (10) moves back and forth to prevent the material from sticking to the inner wall of the fermentation box (1) and affecting the subsequent fermentation effect. At the same time, the scraper (10) moves back and forth to assist in cleaning the fermentation box (1) and improve the cleaning effect. Step 2: At the same time, when the scraper (10) moves, it will drive the pulley frame (11) to move. When the pulley frame (11) moves, it will push the trapezoidal block (16) to move upward. When the trapezoidal block (16) moves upward, it will drive the connecting plate (15), the sliding rod (13) and the sealing plate (14) to move upward. When the sealing plate (14) moves upward, it will break the seal on the liquid outlet pipe (12), so that the inoculum liquid inside the bacterial liquid tank (8) flows into the fermentation tank (1) to assist the fermentation efficiency. Step 3: After the pulley frame (11) disengages from the trapezoidal block (16), the sealing plate (14) will reseal the liquid outlet pipe (12) to prevent waste caused by continuous spraying of inoculum. By intermittently spraying inoculum in conjunction with stirring rod (4), the inoculum and material are mixed more thoroughly, avoiding the inoculum from concentrating in one place of the material, which would result in the material and inoculum not being fully mixed. Step 4: At the same time, when the connecting plate (15) moves upward, it will drive the sliding frame (171) to move upward. When the sliding frame (171) moves upward, it will contact the liquid outlet pipe (12). The reverse force will push the sliding frame (171) to move downward. When the sliding frame (171) moves downward, it will push the short plate (174) to rotate downward. When the short plate (174) rotates downward, it will drive the rotating plate (172) and the baffle (173) to rotate upward. When the baffle (173) rotates upward, it will block the bottom of the liquid outlet pipe (12), so that the sprayed inoculum liquid can splash onto the surface of the material, increase the spread range of the inoculum liquid, and improve the mixing effect.
