Description

Technical Field

[0001] The utility model relates to the technical field of livestock feed processing, in particular to a poultry feed fermentation device. Background Art

[0002] During the production process, poultry feed needs to be fermented in fermentation equipment. This process generally requires a specialized fermentation environment, primarily consisting of fermentation conditions such as temperature and humidity. Prior art Chinese patent document CN212476767U discloses a poultry feed fermentation device. During fermentation, multiple external heat-insulating mechanisms and an internal heat-insulating mechanism ensure consistent fermentation temperatures within the fermentation tank, ensuring the quality of the feed fermentation and the feed product. Furthermore, after fermentation is complete, the fermentation tank can be tilted upward with one end facing upward to allow the feed within the fermentation tank to be discharged through a discharge port. However, this device still has significant drawbacks during use. Its insulation effect is achieved by the flow of water through an insulation pipe, achieving temperature balance across various parts. This heat transfer occurs only near the insulation pipe, leaving the rest of the tank ineffectively. This results in uneven fermentation between the center and outer portions of the fermentation tank. Furthermore, the fermentation tank is complex in structure and requires frequent flipping or rotation, making it inconvenient to use. Utility Model Content

[0014] The specific implementation of the present invention is further described in detail below with reference to the accompanying drawings.

[0015] Depend on Figures 1 to 3 The present invention includes a cylindrical fermentation tank 1, the upper side plate of the fermentation tank 1 is a concave cone, the lower side plate of the fermentation tank 1 is a trumpet-shaped plate with an opening downward, a cylinder 2 is coaxial with the fermentation tank 1, the cylinder 2 and the fermentation tank 1 are fixed together by multiple fixing rods 3, and there is a gap between the upper and lower ends of the cylinder 2 and the fermentation tank 1; a rotating shaft 4 coaxial with the cylinder 2 is provided in the cylinder 2, and a spiral blade 5 is fixed on the rotating shaft 4; when the rotating shaft 4 rotates, the spiral blade 5 can push the material in the cylinder 2 downward and enter the annular space formed between the cylinder 2 and the fermentation tank 1 along the lower side plate of the fermentation tank 1;

[0016] A plurality of feed ports 6 are provided around the upper end of the fermentation tank 1 , and a plurality of discharge ports 7 are provided around the lower end of the fermentation tank 1 . Both the feed ports 6 and the discharge ports 7 are provided with plugs 8 for sealing.

[0017] The upper end of the rotating shaft 4 is connected to a motor 9 , which is fixed to the outer side of the upper end of the fermentation tank 1 .

[0018] In order to conveniently squeeze the material in the cavity of the cylinder 2 into the annular space formed by the cylinder 2 and the fermentation tank 1, thereby realizing the position exchange of the inner and outer layers of the fermentation tank 1, so that the material in the fermentation tank 1 can be fermented evenly, the connection between the outer circular side plate and the upper and lower side plates of the fermentation tank 1 is an arc transition.

[0019] A plurality of support rods 10 are fixed to the lower end of the fermentation tank 1 .

[0020] In order to further facilitate the replacement of the inner and outer layer materials, the lower end of the spiral blade 5 extends out of the cylinder 2, and the inner edge of the lower end of the spiral blade 5 contacts the lower side plate of the fermentation tank 1.

[0021] It is worth noting that the plug 8 is responsible for sealing the feed port 6 and the discharge port 7. In order to leave no dead angle, the inner end of the plug 8 is in contact with the inner wall of the fermentation tank 1. In the top projection, the projection of the feed port 6 is located within the projection of the cylinder 2. In this way, when feeding, the material first fills the cavity of the cylinder 2.

[0022] When in use, the discharge port 7 is blocked with a plug 8, and then the motor 9 is started to pour the material through the multiple feed ports 6. The material falls into the cylinder 2, and the motor 9 drives the spiral blade 5 to rotate through the rotating shaft 4. The spiral blade 5 concentrates the material downward and moves along the lower side plate of the fermentation tank 1. The lower side plate of the fermentation tank 1 is in a cone shape with an opening downward, so that the material moves to the surroundings and eventually gradually enters the annular structure formed between the cylinder 2 and the side wall of the fermentation tank 1. When the material reaches a certain amount, the feed port 6 is blocked and placed in a suitable ambient temperature. The motor 9 stops rotating and fermentation begins; after a period of time, since the heat in the cylinder 2 is not easy to dissipate during the fermentation process, the temperature inside the cylinder 2 is higher than the temperature outside the cylinder 2, and there is a large difference in fermentation efficiency inside and outside the cylinder 2. At this time, the motor 9 is started, and the motor 9 drives the spiral blade 5 to rotate via the rotating shaft 4, so that the material in the cylinder 2 enters the annular space from the lower end of the fermentation tank 1. The original material in the annular space moves upward and finally enters the cavity of the cylinder 2 from the upper end of the cylinder 2, realizing the exchange of the inner and outer layers of the material, so that all the materials in the cavity of the fermentation tank 1 can be fermented evenly.
