High-fiber mixed feed mixing and pelletizing system

Abstract

The invention discloses a high-fiber mixed feed mixing and pelletizing system which comprises a feed mixing system and a pelletizing system, wherein the feed mixing system comprises a raw material cabin, a blending scale, a mixing machine, a spiral conveying machine and a first hopper type lifting machine which are connected in sequence, wherein the pelletizing system comprises a to-be-pelletizedcabin, a pelletizing machine and a cooling tower which are connected in sequence; feed grains cooled in the cooling tower are conveyed into a grading screen through a second hopper type lifting machine; feed grains screened by using the grading screen are connected with a finished product cabin through a conveying pipeline; a modulator of the pelletizing machine is connected with a molasses addition device; a feed mixture is lifted by the first hopper type lifting machine into the inlet of the to-be-pelletized cabin, and is poured into the to-be-pelletized cabin. By adopting the system disclosed by the invention, the uniformity of the molasses and the grain hardness are improved, separation of high-fiber feed raw materials from other feed components is effectively prevented in the conveying process, the mixing uniformity of the feed is ensured, and the system is relatively well applicable to large-scale production and processing.

Description

technical field [0001] The invention relates to the field of feed processing machinery, in particular to a high-fiber compound feed mixing and granulating system. Background technique [0002] High-fiber compound feed is a relative nutritional balance obtained by fully mixing roughage, concentrate and various additives crushed to an appropriate length according to the nutritional needs of ruminants (cattle, sheep, etc.) in different physiological stages. daily ration. Compared with the traditional feeding method of fine-coarse split feeding, the high-fiber compound feed has been widely used in cattle and sheep fattening production due to its simple feeding method, balanced nutrition, good palatability, and high dry matter intake. Molasses is a by-product of the sugar industry. It is a viscous, dark brown, semi-fluid substance. The composition varies with the raw materials and processing conditions of the sugar industry. It mainly contains a large amount of fermentable sugar...

AI Technical Summary

Problems solved by technology

[0003] The existing high-fiber compound feed mixing and granulating system is a concentrated feed mixing and granulating system, which has low mixing and granulating efficiency for high-fiber feed, which easily causes the separation of high-fiber raw materials and other raw materials, and the nutrient uniformity of the finished pellet feed is poor. , unstable quality

The existing feed production line generally chooses to add molasses to the mixer, but this addition method is likely to cause molasses and material agglomeration, which affects the feed mixing efficiency and nutrient uniformity, and is not easy to clean the molasses on the inner wall of the mixer, reducing the service life of the machine
