[0002] Antibiotic-free breeding aims to protect animal health, human health, and produce safe, nutritious livestock products without antibiotic residues, and ultimately results in the production of antibiotic-free animal husbandry. Antibiotic-free fermented feed is a biological fermented feed that uses microorganisms and compound enzyme microbial feed fermentation agent strains to convert feed raw materials into microbial bacterial proteins, bioactive small peptide amino acids, microbial active probiotics, and compound enzyme preparations. This product can not only make up for the amino acids that are easily lacking in conventional feeds, but also quickly convert the nutritional components of other roughage raw materials, promote the reproduction of intestinal flora, and inhibit the growth of pathogenic microorganisms, thereby replacing the use of antibiotics in the diet and reducing the threats of antibiotics to the environment and food safety.

[0003] Most of the existing fermentation devices for antibiotic-free fermented feed for livestock and poultry breeding use heating and cooling equipment directly installed in the fermentation tank. The heating and cooling elements are in direct contact with the fermented material. When the temperature changes, the temperature of the fermented material in contact with the elements changes rapidly, which can easily cause the fermented material to deteriorate and affect the fermentation quality of the overall fermented feed.

[0022] The first sprocket 7 and the second sprocket 20 are both meshed and connected with the chain 21. The first sprocket 7 can be driven to rotate by the motor 6. The transmission through the chain 21 facilitates the rotation of the second sprocket 20, thereby facilitating the outward expansion of the driving force and realizing linkage.

[0023] A center rod 9 is fixedly connected to the axis of the first sprocket 7, and the center rod 9 penetrates the top cover 4 and is fixedly connected to a stirring assembly 10. The stirring assembly 10 includes a stirring frame 11 and a scraper frame 12, and the stirring frame 11 and the scraper frame 12 are both fixedly connected to the outer wall of the center rod 9, and the scraper frame 12 is smoothly fitted with the inner wall of the fermentation tank 3. The center rod 9 periodically reciprocates, which is convenient for driving the stirring frame 11 to rotate to stir the feed, and driving the scraper frame 12 to rotate to clean the inner wall of the fermentation tank 3 to reduce the adhesion of feed.

[0024] A temperature control cylinder 13 is fixedly connected to the outer wall of the fermentation tank 3, and a heat preservation cotton 14 is embedded in the inner wall of the temperature control cylinder 13 near the outer side. An insulation layer 15 is provided on the inner wall of the temperature control cylinder 13, and a heating wire 16 is arranged inside the temperature control cylinder 13. The top and bottom ends of the heating wire 16 are fixedly connected to a fixing ring 17, and the heating wire 16 is arranged in a spiral shape. Compared with a large-area heating plate, the spiral heating wire 16 is lighter in weight. The fixing ring 17 is connected to the inner wall bearing of the temperature control cylinder 13, and the inner wall of the heating wire 16 is smoothly fitted with the outer wall of the fermentation tank 3. The heat can be concentrated on the heating wire 16, and the heat conduction is faster. At the same time, by rotating the heating wire 16 outside the fermentation tank 3, the heating wire 16 can periodically sweep the entire area of ​​the outer wall of the fermentation tank 3, which is actually the same as the heating range of a traditional heating plate.

[0025] The top of the fixing ring 17 near the top of the two fixing rings 17 is fixedly connected with a gear ring 18, and the top bearing outside the temperature control tube 13 is connected with a driven gear 19 corresponding to the gear ring 18. The center of the bottom of the second sprocket 20 is fixedly connected with a connecting rod, which penetrates the top cover 4 and is fixedly connected with the axis of the driven gear 19, so that the second sprocket 20 can transmit the driving force to the driven gear 19. A gear is fixedly connected to the outer wall of the gear ring 18 near the top, and the driven gear 19 is meshed and connected with the gear. The power is transmitted to the gear ring 18 through the driven gear 19, so as to drive the heating wire 16 to rotate. When the fermentation and stirring work starts inside the fermentation tank 3, the heating wire 16 can be synchronously driven to rotate back and forth periodically, and then the heating wire 16 can be flexibly opened and closed according to the temperature requirements.

[0026] A cold air pipe 22 and an exhaust pipe 23 are respectively provided at both ends of the bottom of the temperature control cylinder 13. A cavity is provided between the temperature control cylinder 13 and the fermentation tank 3. One end of the cold air pipe 22 and the exhaust pipe 23 penetrates the bottom of the temperature control cylinder 13 and extends into the cavity. The other end of the cold air pipe 22 is connected to the air outlet of the external air conditioner, so as to inject cold air into the temperature control cylinder 13 and cooperate with the heating wire 16 to adjust the temperature of the fermentation tank 3.

[0027] In this embodiment, a temperature measuring module is embedded in the inner wall of the fermentation tank 3. The staff can control the temperature in the fermentation tank 3 by measuring the data from the temperature measuring module. The outer wall of the middle part of the fermentation tank 3 corresponding to the temperature control tube 13 is made of corrosion-resistant aluminum alloy with good thermal conductivity, which is convenient for heating by the heating wire 16 and supplying cold air to adjust the temperature in the fermentation tank 3.

[0028] When in use, the fermented material is firstly poured into the fermentation tank 3 through the feeding hopper 8, and then the sealing door on the top of the feeding hopper 8 is closed, and then the gas valve 24 in the sealing door is opened to pass the gas required for fermentation into the fermentation tank 3.

[0029] During the fermentation process, the motor 6 drives the first sprocket 7 and the center rod 9 to rotate, driving the stirring assembly 10 to rotate, which can not only stir the fermentation product, but also clean up the feed attached to the inner wall of the fermentation tank 3, so that the fermentation product is mixed more evenly and fully.

[0030] At the same time, the motor 6 drives the second sprocket 20 to rotate through the first sprocket 7 and the chain 21, and drives the driven gear 19 to rotate through the second sprocket 20, and uses the driven gear 19 to drive the gear ring 18 to rotate, thereby driving the heating wire 16 in the temperature control cylinder 13 to rotate. In this device, the outer wall of the fermentation tank 3 is set with a single-layer shell of high thermal conductivity material. Compared with directly setting a heating and cooling mechanism in the fermentation tank 3, the temperature changes slowly and is easier to adjust the temperature, thereby avoiding direct contact between the heating and cooling elements and the fermentation product, resulting in excessively fast heating and cooling speeds and adverse effects on the fermentation product.

[0031] The heating wire 16 provides heating, and the cold air pipe 22 and the exhaust pipe 23 are used to supply cold air to the cavity to provide a cooling effect. The two work together to ensure the environmental temperature required for fermentation. When the fermentation is completed, the discharge valve 2 is opened to take the fermented material out of the fermentation tank 3.

[0032] Although the present invention has been described above with reference to the embodiments, various modifications may be made thereto and parts thereof may be replaced by equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention may be used in combination with each other in any manner, and the fact that these combinations are not exhaustively described in this specification is only for the sake of omitting space and saving resources. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
