A raw material screening device for biomedicine manufacturing

Abstract

The invention discloses a raw material screening device for biomedicine manufacturing, which relates to the technical field of pharmaceutical manufacturing and includes a screening housing, a primary screening mechanism and a secondary screening mechanism. The top of the screening housing is provided with a feed material communicating with the inside The feed channel is provided with a raw material loosening mechanism, and the screening housing is provided with an impurity receiving box and a bearing plate in sequence along the vertical direction, and the preliminary screening mechanism is located directly above the impurity receiving box. The feed channel is located directly above the primary screening mechanism, the secondary screening mechanism is installed on the carrying plate, a protective screen is provided between the impurity receiving box and the carrying plate, and one end of the screening shell is connected from the A discharge port, a closing assembly and a rectangular slot are provided in sequence from top to bottom, a cover is provided on the rectangular slot, and an impurity discharge channel is provided at the other end of the screening housing. The invention can effectively screen and exclude impurities through the primary screening mechanism and the secondary screening mechanism, thereby improving the screening quality.

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
