Description

Technical Field

[0001] This utility model relates to the field of feed fermentation technology, and more specifically, to a fermentation device for a pig feed production line. Background Technology

[0002] With the development of animal husbandry, feed fermentation agents have become increasingly popular among farmers. Fermented feed not only improves the absorption of nutrients and degrades toxins that may be present in feed ingredients, but also greatly reduces the use of antibiotics and other drug additives, improving animal health and thus enhancing the safety of pork products.

[0003] A search revealed that utility model patent CN214270847U discloses a fermentation device for a pig feed processing production line. The device includes a fermentation cylinder with a heater installed on its inner wall. A stirring motor is located at the center of the top of the fermentation cylinder, and a stirring rod is installed at the output end of the motor, penetrating the fermentation cylinder. Stirring blades are fixedly connected to the stirring rod inside the fermentation cylinder. Electric telescopic rods are installed on both sides of the fermentation cylinder, with connecting blocks at the top of the telescopic rods and movable rods fixedly connected to the bottom of the connecting blocks. A lifting ring is fixedly connected to the bottom of the movable rod, penetrating the fermentation cylinder. An annular scraper is connected to the outer side of the lifting ring, and the annular scraper is in close contact with the inner wall of the fermentation cylinder. The fermentation cylinder includes a metal outer shell, a fiberglass insulation layer, and a heat-conducting inner lining. This fermentation device for a pig feed processing production line facilitates the cleaning of materials adhering to the inner wall of the fermentation cylinder and reduces heat transfer and loss.

[0004] However, the above patent still has the following shortcomings: the heater is located at the bottom of the fermentation tank, which makes it difficult to ensure uniform heating of the feed. In addition, the annular scraper can only clean the top of the fermentation tank and is not convenient to clean the bottom of the inner cavity of the fermentation tank, resulting in poor performance. Therefore, we propose a fermentation device for pig feed production line. Utility Model Content

[0005] In view of the problems existing in the prior art, the purpose of this utility model is to provide a fermentation device for pig feed production line.

[0012] Compared with the prior art, the advantages of this utility model are: (1) In this utility model, when the pig feed is fermenting in the inner cavity of the fermentation tank, the exhaust fan is used to make the exhaust pipe generate suction to draw the gas in the inner cavity of the heating tank to the inner cavity of the heating box. The electric heating tube in the inner cavity of the heating box heats the gas. The heated gas is guided back to the inner cavity of the heating tank through the return pipe. The high temperature gas in the inner cavity of the heating tank heats the pig feed in the inner cavity of the fermentation tank, providing a suitable temperature for the fermentation of pig feed. At the same time, the heating tank is located on the side of the inner cavity of the fermentation tank. With the help of the stirring mechanism, the pig feed can be heated evenly.

[0013] (2) In this utility model, during the process of stirring the pig feed by using the speed reduction motor to drive the stirring shaft and stirring blade, the stirring shaft drives the upper scraper and the outer arc plate to rotate synchronously. The outer arc plate scrapes the pig feed off the inner wall of the fermentation cylinder, and the upper scraper scrapes the pig feed attached to the bottom surface of the cover plate, ensuring that the pig feed is fully stirred. When the pig feed is discharged, the upper scraper and the outer arc plate can clean the pig feed attached to the bottom surface of the cover plate and the inner wall of the fermentation cylinder. The structure of the outer arc plate can completely scrape the inner wall of the fermentation cylinder. Attached Figure Description
