Description

Technical Field

[0001] This invention belongs to the field of fermentation equipment technology, specifically relating to a fermentation device for raw materials used in the preparation of saline-alkali land conditioner. Background Technology

[0002] The raw material fermentation device for preparing saline-alkali land conditioner is a specialized piece of equipment used in the production of biological conditioners. Its main function is to process agricultural organic waste (such as straw, mushroom residue, and livestock manure) and specific functional microbial agents through a controlled fermentation process, transforming them into soil conditioner substrates rich in active organic matter, humic acid, and beneficial metabolites. This device typically includes units for raw material pretreatment, quantitative addition, temperature / humidity / pH control, aeration or turning for oxygen supply, and deodorization. Its aim is to create an efficient and stable environment for the proliferation and metabolism of functional microorganisms, thereby producing biological organic conditioners that can improve the physical structure of saline-alkali land, enhance fertility, and reduce saline-alkali stress.

[0003] Existing fermentation equipment typically ferments raw materials for saline-alkali land conditioner in sealed tanks. However, different temperatures significantly affect the composition, activity, and final effect of the fermented product, resulting in varying effects of the final conditioner. To obtain conditioners with different effects, existing equipment requires multiple fermentations of raw materials at different temperatures, necessitating refeeding and temperature control each time. This significantly impacts fermentation efficiency when using a single tank. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a fermentation device for raw materials for preparing saline-alkali land conditioner.

[0005] The technical solution adopted to solve the above technical problems is: a fermentation device for raw materials for preparing saline-alkali land conditioner, including an outer tank, a feeding mechanism installed at the top of the inner side of the outer tank, and a distributing mechanism installed at the bottom of the feeding mechanism inside the outer tank;

[0006] An insulation frame is fixedly connected to the bottom of the outer tank. A material mixing mechanism is installed at the top center of the insulation frame. Multiple fermentation tanks are fixedly installed inside the insulation frame. A stirring mechanism is installed at the center of the interior of each of the multiple fermentation tanks.

[0007] Each of the fermenters is equipped with a sampling mechanism on its outer wall, and a heating mechanism is fixedly installed at the center of the bottom inner surface of the outer tank. The heating mechanism controls the different temperatures of the multiple fermenters.

[0008] Furthermore, the feeding mechanism includes a feeding hopper fixedly connected to the top of the inner wall of the outer tank. A feeding pipe is fixedly connected to one side of the feeding hopper, and the outer end of the feeding pipe penetrates the outer tank. A feeding hopper is fixedly connected to one end of the outer wall of the feeding pipe. A mesh cylinder is fixedly connected to the inner center of the feeding hopper. A spiral feeding blade is rotatably connected to the inner center of the feeding pipe. A first rotating shaft is fixedly connected to the other end of the spiral feeding blade. The other end of the first rotating shaft is rotatably connected to the feeding hopper. Two blade holders are fixedly connected to the outer wall of the first rotating shaft. Multiple crushing blades are fixedly installed between the two blade holders. A first motor is fixedly installed at the outer end of the feeding pipe. One end of the output shaft of the first motor is fixedly connected to the spiral feeding blade.

[0009] Through the above technical solution, the raw materials are poured into the feed pipe through the feed hopper. At this time, the first motor is started, and the output shaft rotates to drive the spiral feed knife to rotate, thereby feeding the raw materials into the mesh cylinder. The rotation of the spiral feed knife also drives the first rotating shaft to rotate, thereby driving multiple crushing blades to rotate, thus breaking up the clumps of raw materials. Pre-breaking up the clumps greatly reduces the load and energy consumption of the subsequent stirring mechanism, and allows the inoculant, moisture and nutrients to come into full contact with the material instantly, improving the overall fermentation efficiency. The crushed material is discharged through the mesh cylinder to the bottom of the feeding hopper, and finally discharged to the distribution mechanism.

[0010] Furthermore, the material distribution mechanism includes a feeding hopper fixedly connected to the bottom of the feeding bin, and a plurality of material distribution pipes fixedly connected to the bottom of the feeding hopper. Each of the plurality of material distribution pipes is equipped with a solenoid valve, and a connecting pipe is fixedly connected to the bottom end of each of the plurality of material distribution pipes.

[0011] Through the above technical solution, the material at the bottom of the hopper flows into multiple distribution pipes by its own weight. When it is necessary to distribute the material into multiple fermentation tanks, the corresponding solenoid valves are opened in sequence, so that the material in the hopper flows into multiple fermentation tanks in sequence, which facilitates the subsequent fermentation of the material in multiple fermentation tanks.

[0012] Furthermore, the insulation frame has multiple insulation cavities inside, and multiple fermentation tanks are installed in the corresponding insulation cavities.

[0013] Through the above technical solution, the insulation frame is equipped with insulation material, which can keep multiple fermentation tanks warm, resulting in higher quality fermented products. Furthermore, different fermentation environments with different temperatures can be set in multiple fermentation tanks to meet different fermentation requirements, thereby obtaining improvers with different effects. There is no need for staff to put raw materials into fermentation tanks for fermentation and processing one time. Improvers with different effects can be obtained in one go, which greatly improves the overall processing efficiency.

[0014] Furthermore, the material mixing mechanism includes a top support frame fixedly connected to the insulation frame. A second rotating shaft is rotatably connected to the top center of the support frame. An arc-shaped stirring blade is fixedly connected to the top of the second rotating shaft. The arc-shaped stirring blade is slidably connected to the bottom inner surface of the hopper. A first gear is fixedly connected to the bottom of the outer wall of the second rotating shaft. A second motor is fixedly installed on one side of the top front end of the support frame. A second gear is fixedly connected to the outer wall of the output shaft of the second motor. The second gear meshes with the first gear.

[0015] With the above technical solution, when the hopper discharges material, the second motor is started, and the output shaft rotates to drive the second gear to rotate, which in turn drives the first gear to rotate, which in turn drives the second shaft to rotate, which in turn drives the arc-shaped stirring blade to rotate. This allows the arc-shaped stirring blade to stir the material at the bottom of the hopper, preventing blockage when the material is discharged into multiple distribution pipes, improving the discharge efficiency, and avoiding the discharge efficiency affecting the final fermentation effect.

[0016] Furthermore, each of the multiple fermenters has a feed inlet at its top and a discharge outlet at its bottom. A temperature sensor is fixedly installed at the top of the interior of each of the multiple fermenters, and each of the multiple connecting pipes is fixedly connected to its corresponding feed inlet.

[0017] Through the above technical solution, the material in the hopper flows to the inlet through the distribution pipe and connecting pipe, and is finally discharged into the fermentation tank. When the fermentation tank ferments the material, the temperature can be monitored at all times by the temperature sensor to prevent the fermentation temperature from not corresponding to the designed temperature. At the same time, different temperatures can be designed to change the final fermentation effect, which is highly functional.

[0018] Furthermore, the stirring mechanism includes a base fixedly connected to the center of the inner surface of the bottom of the fermentation tank, a third rotating shaft rotatably connected between the base and the top of the fermentation tank, a third gear fixedly connected to the top of the outer wall of the third rotating shaft, two connecting frames fixedly connected to the outer wall of the third rotating shaft, a plurality of fourth rotating shafts rotatably connected between the two connecting frames, a fourth gear fixedly connected to the top of the outer wall of each of the plurality of fourth rotating shafts, a first stirring paddle fixedly connected to the outer wall of each of the plurality of fourth rotating shafts, a gear ring fixedly connected to the top of the inner wall of the fermentation tank, and a second stirring paddle fixedly connected to the center of the outer wall of the third rotating shaft.

[0019] Through the above technical solution, when the material is stirred, the rotation of the first gear drives the rotation of multiple third gears, which in turn drives the rotation of the third shaft, which in turn drives the rotation of the second stirring paddle, thereby stirring the material in the central area inside the fermentation tank. The rotation of the third shaft also drives the rotation of two connecting frames, which in turn drives the rotation of multiple fourth shafts, which in turn drives the rotation of the first stirring paddle, thereby stirring the material in the area near the inner wall of the fermentation tank. The rotation of multiple fourth shafts simultaneously drives the corresponding fourth gears to rotate, so that multiple fourth gears mesh and rotate on the gear ring, thereby driving multiple first stirring paddles to rotate. This greatly increases the contact interface between the material and the air, achieving uniform mixing without dead angles, and enhancing the transfer efficiency of oxygen, heat and volatile substances.

[0020] Furthermore, the third gear meshes with the first gear, and the plurality of fourth gears mesh with the gear ring.

[0021] The above technical solution enables the simultaneous revolution and rotation of multiple first stirring paddles, greatly improving the stirring efficiency.

[0022] Furthermore, the sampling mechanism includes a fixed sleeve fixedly connected to the bottom of the outer wall of the fermenter. A limiting pin is fixedly connected to one end of the inner wall of the fixed sleeve. A movable rod is slidably connected to and passes through the center of the fixed sleeve. A sampling tube is fixedly connected to the inner end of the fixed sleeve. The outer wall of the sampling tube is provided with a groove. The outer wall of the movable rod is provided with a limiting groove. The limiting groove is slidably connected to the limiting pin. A fixed ring is rotatably connected to the center of the outer wall of the movable rod. A spring is fixedly connected to one end of the fixed ring. A handle is fixedly connected to the outer end of the movable rod. A drainage tube is fixedly connected inside the bottom of the outer tank. The drainage tube is located below the sampling tube. A receiving cup is threadedly connected to the bottom end of the outer wall of the drainage tube.

[0023] Using the above technical solution, after the materials in multiple fermenters have fermented for a period of time, sampling and testing are required. Workers pull the handle, which in turn moves the movable rod and sampling tube. During the movement, the movable rod rotates due to the cooperation of the limiting groove and the limiting pin. When the handle is pulled a specified distance, the sampling tube is pulled out and rotated 180 degrees, causing the slot to face the top of the drainage pipe. This allows the material inside the sampling tube to be poured into the drainage pipe and finally into the receiving cup. When the handle is released, the movable rod resets via a spring, causing the sampling tube to retract into the fermenter. Workers then rotate the receiving cup to remove it and retrieve the material for testing. Based on the test report, process parameters can be adjusted in a timely manner to optimize fermentation efficiency and improve the quality of the improver.

[0024] Furthermore, the heating mechanism includes heating pipes fixedly connected to the inner walls of multiple fermentation tanks, with wires fixedly connected to the bottom ends of each heating pipe. A heating device is installed at the center of the bottom inner surface of the outer tank, and the other ends of each wire are fixedly connected to the heating device.

[0025] The above technical solution requires the design of multiple fermentation tanks with different temperatures to activate the heating device. The temperature of multiple heating tubes is controlled by wires to heat the material in the fermentation tank. The material can be heated to a specified temperature. The activity and composition of the fermentation product are different at different temperatures, resulting in different final effects. Therefore, it is possible to produce improvers with different effects.

[0026] The beneficial effects of the present invention are as follows: (1) The present invention designs a feeding mechanism to break up the clumps of raw materials before stirring them by using multiple crushing blades. This pre-crushing of clumps greatly reduces the load and energy consumption of the subsequent stirring mechanism and allows the bacteria, water, and nutrients to come into full contact with the materials instantly, thereby improving the overall fermentation efficiency; (2) The present invention designs a heat preservation frame and a temperature sensor to keep multiple fermentation tanks warm, resulting in higher quality fermented products. Furthermore, different fermentation environments with different temperatures can be set in multiple fermentation tanks to meet different fermentation requirements, thereby obtaining different modifiers. This eliminates the need for staff to repeatedly put raw materials into the fermentation tanks for fermentation and processing, allowing for the acquisition of modifiers with different effects in one go, thus greatly improving the overall processing efficiency; (3) The present invention designs a sampling mechanism so that after the materials in multiple fermentation tanks have fermented for a period of time, the materials can be taken out and tested by removing the receiving cup. Based on the test report, the process parameters can be adjusted in a timely manner to optimize the fermentation efficiency and improve the quality of the modifier. Attached Figure Description

Detailed Implementation

[0041] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0042] like Figures 1-5As shown, a fermentation device for raw materials used in the preparation of saline-alkali land conditioner according to this embodiment includes an outer tank 1. A feeding mechanism 2 is installed at the top of the inner wall of the outer tank 1. The feeding mechanism 2 includes a feeding hopper 201 fixedly connected to the top of the inner wall of the outer tank 1. A feeding pipe 202 is fixedly connected to one side of the feeding hopper 201. The outer end of the feeding pipe 202 penetrates the outer tank 1. A feeding hopper 203 is fixedly connected to one end of the top of the outer wall of the feeding pipe 202. A mesh cylinder 204 is fixedly connected to the center of the inner wall of the feeding hopper 201. A spiral feeding blade 205 is rotatably connected to the center of the inner wall of the feeding pipe 202. A first rotating shaft 206 is fixedly connected to the other end of the spiral feeding blade 205. The other end of the first rotating shaft 206 is rotatably connected to the feeding hopper 201. Two blade holders 207 are fixedly connected to the outer wall of the first rotating shaft 206. Multiple [unclear text - possibly related to a specific device or equipment] are fixedly installed between the two blade holders 207. Each crushing blade 208 has a first motor 209 fixedly installed at the outer end of the feed pipe 202. One end of the output shaft of the first motor 209 is fixedly connected to the spiral feeding blade 205. The raw material is poured into the feed pipe 202 through the feed hopper 203. At this time, the first motor 209 is started, and the spiral feeding blade 205 is rotated through the output shaft, thereby driving the raw material into the mesh cylinder 204. At the same time, the spiral feeding blade 205 rotates, driving the first rotating shaft 206 to rotate, thereby driving the multiple crushing blades 208 to rotate, thereby breaking up the clumps of raw material. Pre-breaking up the clumps greatly reduces the load and energy consumption of the subsequent stirring mechanism 7, and allows the inoculant, water, and nutrients to come into full contact with the material instantly, improving the overall fermentation efficiency. The crushed material is discharged through the mesh cylinder 204 to the bottom of the feeding bin 201, and finally discharged into the distributing mechanism 3.

[0043] like Figures 1-13 As shown, a material distribution mechanism 3 is installed inside the outer tank 1 at the bottom of the feeding mechanism 2. The material distribution mechanism 3 includes a feeding hopper 301 fixedly connected to the bottom of the feeding bin 201. Multiple material distribution pipes 302 are fixedly connected to the bottom of the feeding hopper 301. Solenoid valves 303 are installed on each of the multiple material distribution pipes 302. Connecting pipes 304 are fixedly connected to the bottom of each of the multiple material distribution pipes 302. The material at the bottom of the feeding hopper 301 flows to the multiple material distribution pipes 302 by its own weight. When it is necessary to distribute the material into multiple fermentation tanks 6, the corresponding solenoid valves 303 are opened in sequence, so that the material in the feeding hopper 301 flows into the multiple fermentation tanks 6 in sequence, which facilitates the subsequent fermentation of the material in the multiple fermentation tanks 6.

[0044] like Figures 1-7As shown, an insulation frame 4 is fixedly connected to the bottom of the outer tank 1. The insulation frame 4 has multiple insulation cavities 41 inside, and multiple fermentation tanks 6 are installed in the corresponding insulation cavities 41. The insulation frame 4 is filled with insulation material, which can keep the multiple fermentation tanks 6 warm, resulting in higher quality fermented products. Furthermore, different fermentation environments can be set in the multiple fermentation tanks 6 to meet different fermentation requirements, thereby obtaining improvers with different effects. There is no need for staff to put raw materials into the fermentation tanks 6 for fermentation and processing one time. Improvers with different effects can be obtained in one go, which greatly improves the overall processing efficiency.

[0045] like Figures 1-8 As shown, a tamping mechanism 5 is installed at the top center of the insulation frame 4. The tamping mechanism 5 includes a top support frame 501 fixedly connected to the insulation frame 4. A second rotating shaft 502 is rotatably connected between the support frame 501 and its top. An arc-shaped stirring blade 503 is fixedly connected to the top of the second rotating shaft 502. The arc-shaped stirring blade 503 is slidably connected to the bottom inner surface of the hopper 301. A first gear 504 is fixedly connected to the bottom of the outer wall of the second rotating shaft 502. A second motor 505 is fixedly installed on one side of the top front end of the support frame 501. The second motor 505 outputs... A second gear 506 is fixedly connected to the outer wall of the shaft. The second gear 506 meshes with the first gear 504. When the hopper 301 discharges material, the second motor 505 is started. The output shaft rotates to drive the second gear 506 to rotate, which in turn drives the first gear 504 to rotate, which in turn drives the second rotating shaft 502 to rotate, which in turn drives the arc-shaped stirring blade 503 to rotate. This allows the arc-shaped stirring blade 503 to stir the material at the bottom of the hopper 301, preventing blockage when the material is discharged into multiple distribution pipes 302, improving the discharge efficiency, and avoiding the discharge efficiency affecting the final fermentation effect.

[0046] like Figures 1-9 As shown, multiple fermentation tanks 6 are fixedly installed inside the insulation frame 4. Each fermentation tank 6 has a feed inlet 61 at the top and a discharge outlet 62 at the bottom. Temperature sensors 63 are fixedly installed at the top of the interior of each fermentation tank 6. Multiple connecting pipes 304 are fixedly connected to the corresponding feed inlets 61. The material in the discharge hopper 301 flows to the feed inlet 61 through the distribution pipe 302 and the connecting pipe 304, and is finally discharged into the fermentation tank 6. When the fermentation tank 6 ferments the material, the temperature can be monitored at all times by the temperature sensor 63 to prevent the fermentation temperature from not corresponding to the designed temperature. At the same time, different temperatures can be designed to change the final fermentation effect, which is highly functional.

[0047] like Figures 1-10As shown, a stirring mechanism 7 is installed at the center of the interior of multiple fermentation tanks 6. The stirring mechanism 7 includes a base 701 fixedly connected to the center of the inner surface of the bottom of the fermentation tank 6. A third rotating shaft 702 is rotatably connected between the base 701 and the top of the fermentation tank 6. A third gear 703 is fixedly connected to the top of the outer wall of the third rotating shaft 702. Two connecting frames 704 are fixedly connected to the outer wall of the third rotating shaft 702. Multiple fourth rotating shafts 705 are rotatably connected between the two connecting frames 704. A fourth gear 706 is fixedly connected to the top of the outer wall of each of the multiple fourth rotating shafts 705. A first stirring paddle 707 is fixedly connected to the outer wall of each of the multiple fourth rotating shafts 705. A gear ring 708 is fixedly connected to the top of the inner wall of the fermentation tank 6. A second stirring paddle 709 is fixedly connected to the center of the outer wall of the third rotating shaft 702. When stirring the material, the rotation of the first gear 504 drives the rotation of the multiple third gears 703, thereby driving the rotation of the third rotating shaft 702. This rotation drives the second stirring paddle 709 to rotate, thus stirring the material in the central area inside the fermenter 6. The rotation of the third rotating shaft 702 drives the two connecting frames 704 to rotate, which in turn drives multiple fourth rotating shafts 705 to rotate, thereby driving the first stirring paddle 707 to rotate, thus stirring the material in the area near the inner wall of the fermenter 6. The rotation of multiple fourth rotating shafts 705 simultaneously drives the corresponding fourth gears 706 to rotate, so that multiple fourth gears 706 mesh and rotate on the gear ring 708, thereby driving multiple first stirring paddles 707 to rotate, greatly increasing the contact interface between the material and the air, achieving uniform mixing without dead angles, and enhancing the transfer efficiency of oxygen, heat and volatile substances. The third gear 703 meshes with the first gear 504, and multiple fourth gears 706 mesh with the gear ring 708, simultaneously realizing the revolution and rotation of multiple first stirring paddles 707, greatly improving the mixing efficiency.

[0048] like Figures 1-12As shown, sampling mechanisms 8 are installed on the outer walls of multiple fermenters 6. Each sampling mechanism 8 includes a fixed sleeve 801 fixedly connected to the bottom of the outer wall of the fermenter 6. A limiting pin 802 is fixedly connected to one end of the inner wall of the fixed sleeve 801. A movable rod 803 is slidably connected to and passes through the center of the fixed sleeve 801. A sampling tube 804 is fixedly connected to the inner end of the fixed sleeve 801. A groove 805 is provided on the outer wall of the sampling tube 804. A limiting groove 806 is provided on the outer wall of the movable rod 803. The limiting groove 806 is slidably connected to the limiting pin 802. A fixing ring 807 is rotatably connected to the center of the outer wall of the movable rod 803. A spring 808 is fixedly connected to one end of the fixing ring 807. A handle 809 is fixedly connected to the outer end of the movable rod 803. A drainage pipe 810 is fixedly connected inside the bottom of the outer tank 1. The drainage pipe 810 is located below the sampling tube 804. A receiving cup 811 is threadedly connected to the bottom end of the outer wall of the drainage pipe 810. When the materials in multiple fermentation tanks 6 have been fermenting for a period of time, sampling and testing are required. The operator pulls handle 809, which in turn pulls movable rod 803 and sampling tube 804. During the movement, movable rod 803 rotates due to the cooperation of limiting groove 806 and limiting pin 802. When handle 809 is pulled a specified distance, sampling tube 804 is pulled out and rotated 180 degrees, causing the slot 805 to face the top of the drainage pipe 810, thus pouring the material inside sampling tube 804 into the drainage pipe 810, and finally into receiving cup 811. When handle 809 is released, movable rod 803 resets via spring 808, causing sampling tube 804 to retract into fermentation tank 6. The operator then rotates receiving cup 811 to remove the material for testing. Based on the test report, process parameters can be adjusted in a timely manner to optimize fermentation efficiency and improve the quality of the improver.

[0049] like Figures 1-9 As shown, a heating mechanism 9 is fixedly installed at the center of the bottom inner surface of the outer tank 1. The heating mechanism 9 controls different temperatures of multiple fermentation tanks 6. The heating mechanism 9 includes heating pipes 901 fixedly connected to the inner walls of multiple fermentation tanks 6. The bottom ends of multiple heating pipes 901 are all fixedly connected to wires 902. A heating device 903 is installed at the center of the bottom inner surface of the outer tank 1. The other ends of multiple wires 902 are all fixedly connected to the heating device 903. When it is necessary to design different temperatures in multiple fermentation tanks 6, the heating device 903 is activated, and the temperature of multiple heating pipes 901 is controlled through the wires 902, thereby heating the material in the fermentation tank 6. A specified temperature can be heated. At different temperatures, the activity and components of the fermentation product are different, resulting in different final use effects. Therefore, different effects of improvers can be produced.

[0050] The working principle of this embodiment is as follows: the raw material is poured into the feed pipe 202 through the feed hopper 203. At this time, the first motor 209 is started, and the output shaft rotates to drive the spiral feed knife 205 to rotate, thereby driving the raw material into the mesh cylinder 204. While the spiral feed knife 205 rotates, it drives the first rotating shaft 206 to rotate, thereby driving multiple crushing knives 208 to rotate, thereby crushing the lumpy raw material. The crushed material is discharged through the mesh cylinder 204 to the bottom of the discharge bin 201.

[0051] The material at the bottom of the hopper 301 flows by its own weight into multiple distribution pipes 302. When the material needs to be distributed into multiple fermentation tanks 6, the corresponding solenoid valves 303 are opened in sequence, so that the material in the hopper 301 flows into the inlet 61 through the connecting pipe 304, and finally flows into multiple fermentation tanks 6 in sequence. When the hopper 301 discharges material, the second motor 505 is started, and the output shaft rotates to drive the second gear 506 to rotate, which in turn drives the first gear 504 to rotate, which in turn drives the second rotating shaft 502 to rotate, which in turn drives the arc-shaped stirring blade 503 to rotate, so that the arc-shaped stirring blade 503 stirs the material at the bottom of the hopper 301, preventing blockage when the material is discharged into multiple distribution pipes 302.

[0052] Simultaneously, the rotation of the first gear 504 drives the rotation of multiple third gears 703, which in turn drives the rotation of the third rotating shaft 702, which in turn drives the rotation of the second stirring paddle 709, thereby stirring the material in the central area inside the fermentation tank 6. The rotation of the third rotating shaft 702 also drives the rotation of the two connecting frames 704, which in turn drives the rotation of multiple fourth rotating shafts 705, which in turn drives the rotation of the first stirring paddle 707, thereby stirring the material in the area near the inner wall of the fermentation tank 6. While the multiple fourth rotating shafts 705 are rotating, they also drive the corresponding fourth gears 706 to rotate, so that the multiple fourth gears 706 mesh and rotate on the gear ring 708, thereby driving the multiple first stirring paddles 707 to rotate, which greatly increases the contact interface between the material and the air, and achieves uniform mixing and stirring without dead angles.

[0053] Simultaneously, the heating device 903 is activated, and the temperature of multiple heating tubes 901 is controlled by the wire 902 to heat the material in the fermentation tank 6. It can heat to a specified temperature. The activity and composition of the fermented product are different at different temperatures. The temperature sensor 63 can detect the temperature at all times to prevent the fermentation temperature from not corresponding to the designed temperature.

[0054] When fermentation has been going on for a certain period of time, the operator pulls handle 809, which in turn pulls movable rod 803 and sampling tube 804. During the movement of movable rod 803, the interaction between limiting groove 806 and limiting pin 802 causes movable rod 803 to rotate. When handle 809 is pulled a specified distance, sampling tube 804 is pulled out and rotated 180 degrees, causing slot 805 to face the top of drainage pipe 810, thus pouring the material inside sampling tube 804 into drainage pipe 810, and finally into receiving cup 811. When handle 809 is released, movable rod 803 is reset by spring 808, causing sampling tube 804 to retract into fermentation tank 6. The operator rotates receiving cup 811 to remove receiving cup 811 and take out material for testing. Based on the test report, process parameters can be adjusted in a timely manner to optimize fermentation efficiency and improve the quality of improver.

[0055] After the materials in multiple fermentation tanks 6 are optimized, the final fermented product can be discharged through the corresponding discharge port 62.

[0056] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
