Multistage superfine grinding device

Abstract

The invention relates to the technical field of probiotic production equipment, and provides a multistage superfine grinding device. The device comprises a hollow feeding and distributing shaft, and at least two stages of distributing cones are arranged on the inner side of the feeding and distributing shaft, a plurality of material distributing holes are arranged in the position, corresponding tothe lower edges of the upper conical surfaces of the material distributing cones, on the feeding and distributing shaft; except for the last stage of material distributing cone, each stage of material distributing cone is provided with material distributing holes which are communicated up and down, and the aperture of each stage of material distribution holes are smaller than the aperture of thematerial distributing holes of the previous stage; and a sieve tray is arranged on the feeding and distributing shaft and located below each stage of material distributing cone in a rotating mode, andthe sieve trays is provided with sieve holes which are communicated up and down, the sieve trays are driven by the sieve tray driving device to rotate, and the raw materials are crushed and screened.According to the multistage superfine grinding device, raw material particles can be rapidly feeding and distributing, and step-by-step rapid crushing and screening can be realized, so that the crushing efficiency is improved, and the quality of the powder can be ensured.

Description

technical field [0001] The invention relates to the technical field of probiotic production equipment, in particular to a multistage ultrafine pulverization device. Background technique [0002] Probiotic powder is a microorganism that is beneficial to human health and can maintain a healthy intestinal balance. It mainly includes bifidobacteria and lactobacilli, which have the functions of intestinal health, immune enhancement, and regulation. [0003] In the production process of probiotic powder, the raw materials of probiotic powder need to be crushed. Most of the existing ultrafine pulverizers are mechanically agitated, and a large amount of heat is easy to be generated during the stirring process, which is easy to cause damage to the quality of raw materials. Adverse effects, and incomplete crushing, low work efficiency. Contents of the invention [0004] The object of the present invention is to provide a multi-stage superfine pulverization device capable of centrif...
