Description

Technical Field

[0001] This utility model relates to the field of fermentation equipment technology, specifically to an automatic batching and fermentation device for microbial fermentation of feed. Background Technology

[0002] Microbial fermented feed is a feed product made by fermenting feed ingredients using beneficial microorganisms (such as lactic acid bacteria, yeast, and Bacillus). This type of feed has a natural fermented aroma, significantly improving palatability, and contains a large number of beneficial bacteria and digestive enzymes, which help balance the animal's intestinal flora and improve the digestion and absorption of nutrients. Furthermore, microbial fermented feed can degrade and adsorb harmful substances such as mycotoxins and anti-nutritional factors, reducing their harm to animals. Its raw materials are widely available, including crop straw, residues, oilseed cakes, and animal and plant remains. Microbial fermented feed has broad application prospects in animal husbandry, improving animal production performance, reducing breeding costs, and minimizing environmental pollution.

[0003] Microbial fermentation includes aerobic and anaerobic fermentation. Existing fermentation devices cannot achieve adequate aeration or sealing to meet the requirements of aerobic or anaerobic fermentation, which is detrimental to feed fermentation. Therefore, we propose an automated batching and fermentation device for microbial feed fermentation. Utility Model Content

[0004] The purpose of this utility model is to provide an automatic batching and fermentation device for microbial fermentation feed. By providing a perforation on the side of the fermentation tank that communicates with its interior, a first sealing plate with an air vent can be installed to achieve good ventilation with the interior of the fermentation tank, depending on the needs of aerobic or anaerobic fermentation. Alternatively, a second sealing plate can be installed to provide a good aerobic or anaerobic fermentation environment as needed, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic batching and fermentation device for microbial fermentation feed, comprising a fermentation tank and a support frame. The support frame is positioned above the fermentation tank. Feed hoppers, each communicating with the interior and equipped with a first solenoid valve, are provided on both sides of the fermentation tank's surface. Material bins are positioned on both sides of the support frame's surface. The bottom of each material bin is connected to a discharge pipe, communicating with the interior and equipped with a second solenoid valve. The discharge pipes on both sides are positioned above the feed hoppers on both sides. Both sides of the fermentation tank's surface have openings communicating with the interior. A first sealing plate is bolted to the surface of the fermentation tank at each opening. A ventilator is fixed to the side of the first sealing plate. The ventilator is inserted into the fermentation tank through the openings, and its surface has multiple evenly distributed openings. The surface of the first sealing plate has an opening communicating with the ventilator, and a second sealing plate of the same size as the first sealing plate is also provided.

[0006] By adopting the above technical solution, the raw materials are stored in the grain warehouse and can be automatically added to the fermentation tank according to the specified weight. When the first sealing plate with the air vent is installed, good aerobic fermentation can be achieved. Conversely, when the second sealing plate is replaced and the feed hopper is kept sealed, good sealing effect can be achieved for anaerobic fermentation.

[0007] Optionally, the fermenter is equipped with an agitator inside, which is connected to a motor mounted on the top of the fermenter above it.

[0008] By adopting the above technical solution, after the raw materials are put into the fermentation tank, they are stirred and mixed by a stirrer.

[0009] Optionally, the bottom outer ring of the fermenter is vertically fixed with support legs, and a weighing sensor is installed at the bottom of the support legs. The support legs are supported on the ground by the weighing sensor.

[0010] By adopting the above technical solution, different raw materials are added in batches before fermentation, and the amount of different materials added can be weighed.

[0011] Optionally, the first and second sealing plates are provided with through holes at the four corners of their surfaces, through which bolts can pass.

[0012] Optionally, a fine mesh is fixed inside the opening, with the mesh aperture smaller than the particle size of the raw material.

[0013] By adopting the above technical solution, the fermentation material in the fermenter is prevented from entering the ventilation cylinder through the inlet.

[0014] Optionally, the bottom of the fermenter is provided with a discharge pipe communicating with its interior, and a valve is installed on the discharge pipe.

[0015] By adopting the above technical solution, the fermented feed is finally discharged from the discharge pipe.

[0016] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:

[0017] 1. The technical solution of this application provides a perforation on the side of the fermenter that communicates with its interior. Depending on the needs of aerobic or anaerobic fermentation, a first sealing plate with an air vent can be installed to achieve good ventilation with the interior of the fermenter, or a second sealing plate can be installed to provide a good aerobic or anaerobic fermentation environment as needed.

[0018] 2. The technical solution of this application allows the aeration cylinder to be pulled out of the fermenter after the first sealing plate is removed. During use, the aeration cylinder and fine mesh can be cleaned at any time to ensure that the aeration effect is not affected. Attached Figure Description

Detailed Implementation

[0025] Please see Figure 1-4 This utility model provides a technical solution: an automatic batching and fermentation device for microbial fermentation feed, including a fermentation tank 1 and a support 2. Both sides of the surface of the fermentation tank 1 are provided with feeding hoppers 11 communicating with its interior. A first solenoid valve 111 is installed on the feeding hopper 11. The support 2 is placed above the fermentation tank 1. Both sides of the surface of the support 2 are provided with hoppers 21, which are used to hold raw materials and biological fermentation materials. The bottom of the hopper 21 is connected to a discharge pipe 22 communicating with its interior. A second solenoid valve 221 is also installed on the discharge pipe 22. The discharge pipes 22 on both sides are placed above the feeding hoppers 11 on both sides. In use, the raw materials or biological fermentation materials can be added to the fermentation tank 1 through the feeding hoppers 11 by opening the second solenoid valve 221.

[0026] The bottom outer ring of the fermentation tank 1 is vertically fixed with support legs 12, and a weighing sensor 121 is installed at the bottom of the support legs 12. The support legs 12 are supported on the ground by the weighing sensor 121. Each time raw materials or biological fermentation materials are added, they are added separately, so that the amount of raw materials or biological fermentation materials added can be weighed by the weighing sensor 121 each time. The fermentation tank 1 is equipped with a stirrer 13, which is connected to the motor installed on the top of the fermentation tank 1. After the raw materials and biological fermentation materials are added, the motor is started to drive the stirrer 13 to rotate, so that the raw materials are stirred and mixed.

[0027] To achieve a well-ventilated aerobic fermentation environment, both sides of the fermenter 1 are provided with openings 14 that communicate with the interior. A first sealing plate 3 is installed on the surface of the fermenter 1 at the openings 14 using bolts 4. An air vent 31 is fixed to the side of the first sealing plate 3. The air vent 31 is inserted into the fermenter 1 through the openings 14, and multiple openings 311 are evenly provided on the surface of the air vent 31. An opening 32 communicating with the air vent 31 is provided on the surface of the first sealing plate 3. A fine mesh 312 is fixed inside the opening 311. The mesh 312 has a pore size smaller than the particle size of the raw material. During aerobic fermentation, the first solenoid valve 111 of the feed hopper 11 is also kept open, allowing air to enter the air vent 31 through the opening 32. The air vent 311 provides a well-ventilated environment for the interior of the fermenter 1, thus providing an aerobic fermentation environment. The fine mesh 312 prevents raw material particles from entering the air vent 31.

[0028] To achieve a well-sealed anaerobic fermentation environment, a second sealing plate 5 with the same dimensions as the first sealing plate 3 is also provided. The first sealing plate 3 and the ventilator 31 can be removed by unscrewing the bolts 4. The four corners of the surfaces of the first sealing plate 3 and the second sealing plate 5 are provided with through holes 6. The bolts 4 can pass through the through holes 6 to the first sealing plate 3 and the second sealing plate 5, and the second sealing plate 5 can be installed at the through hole 14 in the same way to seal it. At the same time, the first solenoid valve 111 of the feed hopper 11 is kept closed to provide a good sealing environment.

[0029] A discharge pipe connected to the interior of the fermentation tank 1 is installed at the bottom, and a valve is installed on the discharge pipe. After the fermentation reaction is completed, the valve on the discharge pipe can be opened to allow the feed to be discharged from the discharge pipe.

[0030] In use, the first solenoid valve 111, the second solenoid valve 221, the weighing sensor 121, and the motor of the agitator 13 are all connected to the industrial control computer. The fermentation raw materials and the biological fermentation material used for fermentation are placed in different silos 21. When feed fermentation is required, the first solenoid valve 111 is kept open. The second solenoid valve 221 on the bottom discharge pipe 22 of one of the silos 21 is opened first, so that the raw materials are discharged through the discharge pipe 22 and enter the fermentation tank 1 through the feed hopper 11. The weighing sensor 121 weighs and obtains the amount of raw materials to be added. When the required amount is added, the second solenoid valve 221 is closed. Then, the raw materials in the other silo 21 are added to the fermentation tank 1 in the same way through the feed hopper 11. After that, the motor is started to drive the agitator 13 to rotate and stir and mix the raw materials. During aerobic fermentation, the first solenoid valve 111 is kept open, allowing external air to enter the ventilation cylinder 31 through the inlet 311. This ventilation cylinder 311 creates good airflow within the fermentation tank 1, ensuring a favorable aerobic fermentation environment. During anaerobic fermentation, before adding the raw materials, the bolts 4 are loosened to remove the first sealing plate 3 and the ventilation cylinder 31. The second sealing plate 5 is then replaced with the bolts 4, which are used to lock and seal the opening 14. During fermentation, the first solenoid valve 111 is kept closed, thus providing a sealed anaerobic fermentation environment. During both aerobic and anaerobic fermentation processes, the agitator 13 can be activated to further agitate the materials. After fermentation is complete, the valve on the bottom discharge pipe is opened to discharge the fermented feed.
