Description

Centrifugal coarse and fine material sorting device for livestock and poultry feed production granulator and implementation method

Technical Field

Background

The feed is a general term for food for all human-raised animals, and in a narrower sense, the general feed mainly refers to food for agricultural or animal-raising animals.

Classified according to the level of meeting the nutritional needs of animals, feed products can be divided into:

(1) complete compound feed. The complete compound feed is a feed which meets the requirements of animals on protein, energy, macromineral, trace mineral, vitamin and various nutritional and non-nutritional additives. The complete compound feed can be directly fed to animals.

(2) And (4) concentrating the feed. The energy feed such as corn, wheat, bran and the like in the formula of the concentrated feed accounts for more than 50 percent of the formula, and the raw materials are most produced by breeding manufacturers or purchased by the manufacturers. In order to reduce the transportation cost, a feed producer designs a feed product without energy raw materials, and after purchasing the product, a breeding dealer mixes the product with the self-produced or self-purchased energy raw materials to produce the complete formula feed with relatively low cost.

(3) And (4) premixing feed. In order to further meet the requirements of scale feeders on refined feeding and cost reduction, feed producers design premixed feed products, which mainly contain minerals, vitamins and various nutritional and non-nutritional additives. The product has the characteristics of low addition proportion, high nutrient concentration, high mixing difficulty, high product value, high technical content and high storage requirement.

The existing method for producing and granulating livestock and poultry feed needs to screen and grade according to the particle size of feed particles.

The existing feed screening device is generally used for primary screening, and the screening effect is poor; and the mode that the screen cloth adopted fixed mounting mostly, screening efficiency exists and promotes the space to also be inconvenient with the fodder quick discharge after the screening is accomplished.

Therefore, the inventor designs a centrifugal coarse and fine material sorting device for a livestock and poultry feed production granulator and an implementation method thereof, and aims to solve the problems.
