Description

TECHNICAL FIELD

[0001] The application relates to the technical field of stirring equipment, in particular to a stirring equipment for preparing amino acid feed. BACKGROUND

[0002] In the industrial production of amino acid feed, the fusion of base feed components such as grain powder and soybean meal and trace amino acid raw materials is a core problem. The former has a large volume, and the latter has a very small amount and various forms. If mixed improperly, it is easy to cause nutritional deviation or material waste. The core equipment of this link is the stirring equipment for preparing amino acid feed, which is a special machine specially used for uniformly mixing amino acid raw materials and other feed components. It needs to adapt to different material characteristics and meet the precision and hygiene requirements of feed production.

[0003] For example, the patent number CN210356831U discloses a feed stirring preparation machine, which comprises a shell, a bin, a crushing device, a material returning device one and a material returning device two. The bin is located inside the shell and is provided with a feeding port at one end. The crushing device is rotatably arranged at the bottom of the bin. The material returning device one and the material returning device two are respectively arranged on the two sides of the crushing device in a symmetrical manner and are rotatably arranged on the inner wall of the shell. The material returning device one comprises a stirring shaft one arranged in parallel with the crushing device, and a spiral blade one arranged on the stirring shaft one. The spiral blade one is provided with a plurality of forks on the side close to the feeding port. The forks are uniformly distributed on the stirring shaft one. The fork comprises a first prong plate arranged along the axis direction of the stirring shaft one. The two ends of the first prong plate are both provided with a second prong plate arranged perpendicularly. The second prong plate is perpendicular to the stirring shaft one. The edge of the second prong plate is arc-shaped. The height of the second prong plate gradually decreases along the direction away from the first prong plate.

[0004] However, in the prior art, the trace addition of amino acid raw materials in the material during the stirring process makes them in a "weak dispersion state" in the large base feed system. The volume of base feed components such as grain powder and soybean meal accounts for an absolute dominant position. The amino acid particles are easily wrapped or "wrapped and carried" by the base material and are difficult to diffuse independently. At the same time, the significant differences in density, particle size and fluidity between the two further aggravate the dispersion difficulty, resulting in a serious loss of control of feed nutrition precision. The "local enrichment" area can cause animals to intake excessive amino acids, increase the burden on metabolic organs such as liver and kidney, and even cause poisoning reactions. The "local deficiency" area cannot meet the needs of essential amino acids for animal growth and reproduction, causing problems such as slow weight gain of livestock and poultry, decreased egg production rate and reduced immunity.
