Description

Technical Field

[0001] The invention relates to the technical field of feed processing equipment, in particular to an internal circulation mixing device for biological fermentation antibiotic-free feed. Background Art

[0002] Feed is widely used in pig farming. In order to enable pigs to grow quickly, fatten and strengthen, various nutrients or solvents such as probiotics are added to the feed during pig feed production. Therefore, the demand for a stirring device for bio-fermentation and antibiotic-free feed is growing. Since the solvent is usually liquid, it will cause the feed to clump after contacting the feed, resulting in uneven mixing of the feed and the nutrient solution, and the clumps will harden after a period of time, and are not easy to break up during stirring, affecting the quality of the feed. The feed has greater viscosity after mixing with the solvent, resulting in uneven mixing of the feed, and if the feed sticks to the casing for too long, the feed will deteriorate and mold. To address this problem, the existing patent announcement number CN201921516192.6 discloses a mixing device. Although the device can scrape the material during operation, it can only stir the feed horizontally, and the stirring effect is not good.

[0003] In view of the above problems, an improved internal circulation mixing device for feed is now provided. Summary of the invention

When the rotating cylinder rotates, under the action of the lifting blades, the material will slide upward along the lifting channel and then be discharged along the overflow holes, thereby forming longitudinal convection. Compared with traditional single horizontal stirring, the combination of longitudinal convection and horizontal stirring in the present application greatly improves the stirring effect on the material.

[0009] As a further solution of the present invention: the bottom of the mixing box is a conical bottom plate for facilitating the collection of materials.
