[0003] The existing patent document CN221681116U discloses a solid feed enzymatic hydrolysis and fermentation device. This utility model has a pH detector at the lower part of the rotating shaft and a temperature control device inside the tank. The pH detector and the temperature control device are connected to the control panel set outside the tank by wires. Using this device can greatly improve the efficiency of cottonseed enzymatic hydrolysis.

If these materials are not cleaned in time, it will directly affect the fullness of solid feed fermentation and thus affect the quality of the finished solid feed product. Utility Model Content

The cleaning plate 403 is fully attached to the inner wall of the fermentation tank 1. The motor 2 drives the drive shaft 3 to rotate, which in turn drives the stirring blade 401 to rotate and stir the feed raw materials. At the same time, the connecting rod 402 drives the cleaning plate 403 to rotate under the rotation of the drive shaft 3, scraping off the raw materials attached to the inner wall of the fermentation tank 1.

[0027] The auxiliary mechanism 5 includes a feed inlet 501, which is fixedly installed on the outer surface of the fermentation tank 1. A water inlet 502 is fixedly installed on the outer surface of the fermentation tank 1 away from the feed inlet 501. An air inlet 503 is fixedly installed on the outer side of the fermentation tank 1, with one end of the air inlet 503 extending into the interior of the fermentation tank 1. An exhaust port 504 is installed on the outer surface of the fermentation tank 1 above the water inlet 502. A discharge port 505 is fixedly installed at the bottom of the fermentation tank 1. The temperature control mechanism 6 includes a temperature sensor 601, which is fixedly installed... A temperature control sleeve 602 is fixedly connected to the outer surface of the fermentation tank 1, installed at the top inside the fermentation tank 1. A water inlet pipe 603 is provided on one side of the temperature control sleeve 602. One end of the water inlet pipe 603 passes through the temperature control sleeve 602 and is fixedly connected to a heat exchange pipe 604, which is located inside the temperature control sleeve 602. A water outlet pipe 605 is fixedly connected to the end of the heat exchange pipe 604 away from the water inlet pipe 603. The end of the water outlet pipe 605 away from the heat exchange pipe 604 extends to the outside of the temperature control sleeve 602.

When using this device for enzymatic fermentation of solid feed, the operator pours the feed raw materials into the fermentation tank 1 through the feed inlet 501, adds an appropriate amount of water through the water inlet 502, and introduces oxygen through the air pipe 503. The operator can depressurize the fermentation tank 1 by adjusting the valve inside the exhaust port 504. The temperature sensor 601 monitors the temperature inside the fermentation tank 1. The system allows staff to monitor the ambient temperature during the enzymatic hydrolysis and fermentation of solid feed. Then, staff introduce water at a specific temperature into the heat exchange tube 604 through the inlet pipe 603. The water inside the heat exchange tube 604 exchanges heat with the first heat-conducting wall 606, causing the water temperature inside the heat exchange tube 604 to decrease. The first heat-conducting wall 606 then exchanges heat with the second heat-conducting wall 607, causing the temperature inside the fermentation tank 1 to rise. The water that has absorbed heat is discharged through the outlet pipe 605. This cycle is repeated to regulate the temperature inside the fermentation tank 1, ensuring more even heating of the feed ingredients.

[0028] Working Principle: When using this device for enzymatic fermentation of solid feed, the operator pours the feed raw materials into the fermentation tank 1 through the feed inlet 501, adds an appropriate amount of water through the water inlet 502, and introduces oxygen through the air inlet 503. The operator can depressurize the fermentation tank 1 by adjusting the valve inside the exhaust port 504. The motor 2 drives the drive shaft 3 to rotate, which in turn drives the stirring blade 401 to rotate, agitating the feed raw materials. At the same time, the connecting rod 402, under the rotation of the drive shaft 3, drives the cleaning plate 403 to rotate, scraping off the raw materials adhering to the inner wall of the fermentation tank 1. Temperature sensor 601 monitors the temperature inside fermentation tank 1, allowing staff to control the ambient temperature for solid feed enzymatic hydrolysis fermentation. Then, staff introduce water at a certain temperature into heat exchange tube 604 through water inlet pipe 603. The water inside heat exchange tube 604 exchanges heat with the first heat-conducting wall 606, causing the water temperature inside heat exchange tube 604 to decrease. The first heat-conducting wall 606 exchanges heat with the second heat-conducting wall 607, causing the temperature inside fermentation tank 1 to rise. The water that has absorbed heat is discharged through water outlet pipe 605. This cycle is repeated to regulate the temperature inside fermentation tank 1, making the feed raw materials heat more evenly.
