Raw material screening device for biomedical manufacturing

Abstract

The invention discloses a raw material screening device for biomedical manufacturing, and relates to the technical field of biomedical manufacturing. The raw material screening device for biomedical manufacturing comprises a screening shell, a primary screening mechanism and a secondary screening mechanism; a feeding material channel which communicates with the interior of the screening shell is formed in the top of the screening shell; a raw material loosening mechanism is arranged in the feeding material channel; an impurity receiving box and a bearing plate are arranged in the screening shell in sequence in the vertical direction; the primary screening mechanism is positioned right above the impurity receiving box; the feeding material channel is positioned right above the primary screening mechanism; the secondary screening mechanism is mounted on the bearing plate; a protective baffle net is arranged between the impurity receiving box and the bearing plate; one end of the screening shell is provided with a discharging hole, a closing component and a rectangular groove in sequence from top to bottom; a sealing cover is arranged on the rectangular cover; and an impurity discharging channel is formed in the other end of the screening shell. According to the raw material screening device for biomedical manufacturing, impurities can be effectively screened and removed through the primary screening mechanism and the secondary screening mechanism, so that the screening quality is improved.

Description

technical field [0001] The invention relates to the technical field of pharmaceutical manufacturing, in particular to a raw material screening device for biomedical manufacturing. Background technique [0002] With the development of science and technology, it has been found that the active ingredients that can inhibit or treat diseases in the raw materials of traditional Chinese medicine and biomedicine generally exist in the cells of animals and plants, and the content is very low. The active ingredients of many Chinese herbal medicines will grow with the time of plant growth. The longer the growth time, the harder the rhizomes and branches of plants will be. In order to obtain those active ingredients, the traditional methods include boiling, fermenting, processing, etc., and in the process of pharmaceutical manufacturing, it is necessary to For screening and removing impurities, traditional screening devices cannot effectively screen out impurities in raw materials, whic...

AI Technical Summary

Problems solved by technology

However, this invention still has many deficiencies: 1. The impurities mixed with biomedical raw materials are generally small in size or light in weight, and there is a defect that all impurities cannot be effectively screened out by using the screening method of comparison files

2. The material on the sieve after screening cannot be taken out
