A fermentation method for compound microbial fermented feed, including the following steps:

S1: Prepare for the operation, put a variety of initial materials and enzyme-bacteria combined feed starter into a temporary container, and add warm water at 30-34°C;

S2: Pour warm water into the container to make the overall water content reach 55%-60%, seal it and let it stand for 10-12 hours. During this process, maintain appropriate temperature and humidity;

S3: Open the movable top cover 4 at the top of the mixer 1, pour the entire resting feed into the mixer 1, control the driving mechanism 2 of the mixer 1 to operate, and fully mix the entire raw materials of the fermented feed;

S4: Take out the mixed feed from the mixer 1, clean the inside of the mixer 1, dry the taken-out feed, and then store it to prevent deterioration.

During the mixing step, the moving top cover 4 is opened, the feed is put into the mixer 1, and the driving mechanism 2 is controlled to operate. The driving mechanism 2 drives the mixing shaft to rotate, and the feed is mixed in the mixer 1. After the mixing is completed, the The feed is taken out from the mixer 1, and then the coil 14 on the bearing of the driving mechanism 2 is controlled to be energized. After the coil 14 is energized, the electromagnetic block 15 on the coil 14 is energized at the same time. Since the electromagnetic block 15 is magnetically repelled by the magnet block 18 after being energized, the current is energized. The rear electromagnetic block 15 pushes the magnet block 18 to move in the direction away from the coil 14. The magnet block 18 drives the sliding sleeve 17 fixedly connected with it to slide on the rectangular shaft 16. The tension spring 19 cooperates to stretch, and the sliding sleeve The plug shaft 36 at the top of 17 is inserted into the rectangular slot 35 through the tapered head. At this time, when the driving mechanism 2 operates again, it will drive the docking shaft 34 to rotate at the same time. The docking shaft 34 is driven by the pulley set 41, and then drives the The power shaft 9 at the top of the connecting plate 33 rotates at the same time, and the power shaft 9 further drives the wind wheel 10 to rotate in the wind hood 8. At this time, air flow is generated in the wind hood 8, and the air inlet end of the wind hood 8 is responsible for inhaling air from the outside. , and the suction force generated in the air inlet pipe 20 at the air inlet end will pull the sliding rod 23 inward through the ventilation block 21 and squeeze the first spring 22. The sliding rod 23 moves into the air inlet pipe 20. When sliding, the blocking plate 12 is pulled by the driving block 24 at the same time. After the blocking plate 12 is driven, the water inlet 5 on the fixed top cover 3 is exposed. At this time, water is injected into the mixer 1 through the water inlet 5, and the mixer 1 cooperates with the operation. When cleaning is carried out and the sliding rod 23 moves to the point where it cannot move, in order to ensure the air flow in the air hood 8, the suction force generated by the air inlet end of the air hood 8 will cause the bump 30 to slide into the air inlet sleeve 26. When the block 30 squeezes the second spring 31, the external air enters the air inlet sleeve 26 through the top gap, and enters the air hood 8 through the multiple sets of air inlet holes 28 opened on the support block 27, thereby ensuring the air flow. flow, thereby keeping the whole functioning;

When clean water is injected to clean the inside of the mixer 1, the power shaft 9 on the wind wheel 10 drives the reciprocating screw 38 to rotate at the same time. Through the thread connection between the reciprocating screw 38 and the threaded sleeve 39, the threaded sleeve 39 is rotated on the reciprocating screw. The rod 38 moves back and forth, and the threaded sleeve 39 drives the scraper 40 fixedly connected to it to move. During the sliding process of the scraper 40 with the mixer 1, at the same time, the top end of the scraper 40 fits the inside of the moving top cover 4, and the movement of the scraper 40 is prevented. The feed residue adhered to the top cover 4 is scraped so that the residue falls into the cleaning water below. After cleaning, the cleaning water in the mixer 1 can be discharged. The air outlet pipe 11 provided at the air outlet end of the air hood 8 is connected to The inside of the mixer 1 is connected. When air flows in the air hood 8, the generated wind is discharged from the air outlet pipe 11 and blows the inside of the mixer 1 that has just been cleaned, thereby increasing the drying rate inside the mixer 1. When the staff While drying the mixed fermented feed, the inside of the mixer 1 is cleaned, which saves manpower and improves work efficiency.
