Feed conditioning granulator

Abstract

The invention belongs to the technical field of feed production devices, and discloses a feed conditioning granulator. The feed conditioning granulator is mainly technically characterized by comprising a frame body, a feeding mechanism, a conditioner and a granulating mechanism, wherein the conditioner comprises a power mechanism, a shell with a feed port and a discharge port, a stirring shaft andstirring fins located on the stirring shaft; and spiral fin plates are arranged, opposite to the feed port and the discharge port, on the stirring shaft. After materials enter from the feed port, thefirst spiral fin plate on the stirring shaft located at the feed port pushes the materials forwards rapidly, feeding is more uniform, the materials and steam are fully mixed under the action of the stirring fins on the stirring shaft, and due to the fact that the first spiral fin plate and the second spiral fin plate are arranged at the two ends of the stirring shaft, the steam is sealed in the conditioner, the steam cost is saved, and the heat loss is avoided, so that the temperature is higher in the conditioning process, and the conditioning and sterilizing effects are greatly improved.

Description

technical field [0001] The invention belongs to the technical field of conditioning and granulating machinery, and in particular relates to a feed conditioning and granulating machine. Background technique [0002] Due to the low ability of most animals to digest starch, in the field of feed processing, powdery materials need to be matured. In the conditioner, saturated steam contacts with the material, and a large amount of heat is released when the surface of the powder is condensed. Absorption raises the temperature of the powder to 80-88°C, greatly increases the degree of gelatinization of the starch under the action of hydrothermal heat, and also promotes the thermal denaturation of the protein in the material. The denatured protein is easy to be enzymatically hydrolyzed, thereby improving The digestion and utilization rate of the pellet feed is improved, and the denatured protein can fully play the role of a binder, effectively bonding other components around it, and u...

AI Technical Summary

Problems solved by technology

The above-mentioned feed conditioning granulator has the following defects: First, because the filling degree of the material in the shell is only about two-thirds during the conditioning work, the steam is easy to run away at the inlet and outlet, resulting in The waste of steam increases the cost of steam in the production process; secondly, when the material is added into the charging port, the material is easy to accumulate at the feeding port, and the production efficiency is reduced; thirdly, the processed material is not easy to discharge from the discharge port Fourthly, since the two ends of the conditioner are provided with a feed inlet and a discharge port, not only the loss of steam is caused, but also the internal temperature of the conditioner is low and the temperature is uneven, the protein is thermally denatured and the bactericidal effect is poor, and the feed greatly reduced quality
