A low temperature ultrafine pulverizer

Abstract

The invention belongs to the technical field of agricultural machines, and particularly relates to a low-temperature ultra-micro pulverizer. The low-temperature ultra-micro pulverizer is suitable for pulverizing of multiple feedstuffs. The pulverizer comprises an upper box body (3), a lower box body (1), an output transmission device and a reciprocating motion device; a door cover (2) and a liquid nitrogen injection opening (6) are arranged on the upper box body (3); the output transmission device comprises a motor seat (4), a motor (5), a coupler (7), a transmission shaft (8), a bearing pedestal (9), a clamping ring (11), an eccentric wheel (13) and a bearing (14); and the reciprocating motion device comprises a square tube (12), a top plate (16), sliding blocks (17), a pulverizing chamber (18), a pulverizing tank basket (21) and a pulverizing tank (23). The low-temperature ultra-micro pulverizer is small in size and convenient to carry; and liquid nitrogen is used for providing low-temperature environment, the fodder pulverizing granularity is small, the frequency of the motor and the reciprocated work stroke can be changed according to the variety of materials, and the pulverizing tank is placed and taken out conveniently and rapidly.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, in particular to a low-temperature ultrafine pulverizer. Background technique [0002] The purpose of feed milling is to increase the surface area of ​​the feed and reduce the particle size. Increasing the surface area can improve the palatability and ease of digestion; reducing the particle size makes the subsequent storage, granulation and other processes more convenient and efficient. [0003] The crushing of feed raw materials is a very important link in feed processing. The particle size of the crushed raw materials has an important impact on the difficulty of the subsequent process and the quality of the finished product, and the size of the crushed particle size also affects the production cost. The smaller the crushing particle size, the easier it is to be absorbed and granulated, and the power consumption is also increased. Therefore, as the main equipment of feed proces...

AI Technical Summary

Problems solved by technology

[0004] Commonly used pulverizers still have some problems. For some raw materials with low melting point, when they are pulverized at high speed, the temperature is too high, which will easily cause the raw materials to melt and the pulverization effect is poor.

In addition, for those materials with many fibers, the crushing effect is not good
