Pharmaceutical pill screening device

Abstract

The invention discloses a pharmaceutical pill screening device. The device structurally comprises a dustproof cover, an observation hole window, a screen frame, a pressing ring, a discharge port, a pressure valve, a spring bolt and a base. The dustproof cover is provided with the observation hole window and is connected with the screen frame, and the pressing ring is arranged at the edge positionof the screen frame. The device has the advantages that the air flow type and the configuration are improved on the structure, firstly, a through gas machine on the screen frame is utilized to achievelow-temperature dehumidification, hot air is prevented from re-generating water molecules to adhere to the surfaces of pills after meeting cold, and swinging of a turnover wheel generates a stirringand overturning effect on the pills left on the surface of the turnover wheel, so that the pills are in contact with cold air in all directions and dehumidified; and finally, a graded supporting rod is matched with a screen plate for vibration, the pill overturning action is realized, and the purposes of dead-corner-free cold air covering and dehumidifying of the pills are achieved.

Description

Technical field [0001] The invention relates to the field of chemical pharmacy, in particular to a pharmaceutical granule screening device. Background technique [0002] Chemical pharmacy mostly adopts the proportioning method to combine the medicines, especially the composition of the traditional Chinese medicine granules are manufactured by screening the best excipients by investigating the index of the medicine particles. During the manufacturing process, the humidity of the medicine particles must be strictly controlled. In order to reduce the influence of moisture on the properties and stability of the drug, once the moisture exceeds the standard, it will seriously affect the validity period of the drug granules, because some of the drug components contained in the drug granules will be hydrolyzed and deteriorated, and due to the different characteristics of the drug granules, heating is used. The influence of high temperature on the drug is uncertain, and the moisture dehum...

AI Technical Summary

Problems solved by technology

[0002] Chemicals and pharmaceuticals are mostly made by combining drugs in a proportioning manner. In particular, the composition of traditional Chinese medicine granules is manufactured by screening the optimal excipients through the inspection of the drug granules. During the manufacturing process, the humidity of the granules must be strictly controlled. In order to reduce the impact of moisture on the properties and stability of the drug, once the moisture exceeds the standard, it will seriously affect the validity period of the pills, because some pharmaceutical ingredients contained in the pills will be hydrolyzed and deteriorated, and due to the different characteristics of the pills, the heating method produces The impact of high temperature on the drug is uncertain, and there is also a big difference in the moisture drainage. The moisture of the medicine particles dried by hot air is easy to regain moisture and reattach to the surface of the medicine grains, and the excess water on the medicine grains cannot be effectively removed. Based on The above premise, this case developed a pharmaceutical drug particle screening equipment to solve this problem
