The microorganism expansion liquid is stored and homogenized in the intermediate storage tank, and the microorganism expansion liquid is quantitatively supplied to the fermentation tank, which can ensure the stability of the quality of the microorganism expansion liquid entering the fermentation tank and the accurate measurement of the supply. The feed raw materials are quantitatively supplied to the fermentation tank through the feeding mechanism, and the feed raw materials and the microorganism expansion liquid are fully mixed in a suitable fermentation environment through the fermentation tank, which is conducive to improving the fermentation efficiency of the feed raw materials and thus improving the production efficiency of the microbial feed. The invention patent with patent number CN201811041217.1 discloses an invention patent. A composite microbial fermentation feed preparation machine can facilitate efficient crushing of raw materials through a crushing plate, and the qualified raw materials are transported to the preparation box through a screening net. Since the fixed block drives the screening net to rotate, it can help improve the screening efficiency of the raw materials and avoid clogging.

After the squeegeeing is completed, the solenoid valve 1 is opened, and the cultured bacteria fall into the inner side of the fermentation tank through the connecting pipe to ferment the raw materials. During the squeegeeing and fermentation process, the motor drives the lower sleeve to rotate clockwise through the gear 1, and the lower sleeve drives the inner horizontal pipe, and the inner horizontal pipe drives the inner vertical pipe through the connecting block to rotate clockwise.

The high-pressure cleaning liquid in the upper annular cavity is sequentially passed into the inner sides of the inner horizontal pipe and the inner vertical pipe, and the one-way valve is opened by water pressure, and is sprayed out at high pressure toward the corners of the fermentation tank or expansion tank through the oblique mouth. The high-pressure cleaning liquid in the outer vertical pipe, outer horizontal pipe, inner horizontal pipe and inner vertical pipe pushes open the sealing plate in the nozzle by pressure, and the sealing plate is twisted The spring rotates outward, and the cleaning liquid is sprayed outward through the nozzle, effectively cleaning the fermentation tank and the expansion tank. Due to the recoil effect of the nozzle, the outer horizontal tube spins on the connecting block, the upper sleeve and the lower clamping ring respectively, the outer vertical tube spins on the connecting block, the inner horizontal tube spins on the connecting block, the lower sleeve and the upper clamping ring respectively, and the inner vertical tube spins on the connecting block, and remains connected through the interface and the card cavity, so that the outer horizontal tube, the outer vertical tube, the inner horizontal tube and the inner vertical tube continuously rotate on the inside of the fermentation tank and the expansion tank, effectively cleaning the fermentation tank and the expansion tank in any direction, avoiding residue adhering to the corners and crevices in the fermentation tank and the expansion tank and being unable to be effectively cleaned, thereby ensuring the cleaning effect of the fermentation tank and the expansion tank.

[0017] 3. When the microbial feed expansion and fermentation system is in use, when the fermentation tank and the expansion tank are being cleaned, the outer horizontal tube, outer vertical tube, inner horizontal tube and inner vertical tube are spinning by the water pressure of the sprayed cleaning water, and the motor drives the lower sleeve to rotate clockwise through gear 1, and drives the upper sleeve to rotate counterclockwise through gear 2 and the gear ring, so that the outer horizontal tube and outer vertical tube are constantly intersecting with the inner horizontal tube and inner vertical tube, and cleaning each other during the intersection process, thereby effectively preventing residue from adhering to the outer horizontal tube, outer vertical tube, inner horizontal tube and inner vertical tube and being difficult to be cleaned off, so that the automatic cleaning structure can perform self-cleaning work, and there is no need for personnel to clean the cleaning equipment, which greatly reduces manpower consumption and facilitates the use of the equipment.

As a result, the outer horizontal tube 15, the outer vertical tube 14, the inner horizontal tube 17 and the inner vertical tube 16 continuously rotate inside the fermenter 1 and the expansion tank 2, effectively cleaning the fermenter 1 and the expansion tank 2 in any direction.In order to prevent residue from adhering to the corners and crevices inside the fermentation tank 1 and the expansion tank 2 and being unable to be effectively cleaned, and to ensure the cleaning effect of the fermentation tank 1 and the expansion tank 2, when the fermentation tank 1 and the expansion tank 2 are being cleaned, the outer horizontal pipe 15, the outer vertical pipe 14, the inner horizontal pipe 17 and the inner vertical pipe 16 are rotating by the water pressure of the sprayed cleaning water, and the motor 9 drives the lower sleeve 11 to rotate clockwise through the gear 12, and drives the upper sleeve 10 to rotate counterclockwise through the gear 2 13 and the gear ring 33, so that the outer horizontal pipe 15 and the outer vertical pipe 14 are constantly intersecting with the inner horizontal pipe 17 and the inner vertical pipe 16, and in the process of intersection, they clean each other, thereby effectively preventing residue from adhering to the outer horizontal pipe 15, the outer vertical pipe 14, the inner horizontal pipe 17 and the inner vertical pipe 16 and being difficult to be cleaned, so that the automatic cleaning structure can perform self-cleaning work, without the need for personnel to clean the cleaning equipment, greatly reducing manpower consumption and facilitating the use of the equipment.
