Abstract

The invention belongs to the technical field of pharmacy, and particularly relates to a vacuum drying device for pharmacy. The vacuum drying device aims to solve the problem that in the prior art, themedicine vacuum drying effect is poor. According to the scheme, the vacuum drying device comprises a drying box, wherein a top box and a bottom box are fixed to the top and the bottom of the drying box respectively, vacuum exhaust pipes are connected to the bottom of the top box, and heating pieces are connected to the top of the bottom box; and a fixing frame with the section of a rhombus structure is fixed to the inner wall of the drying box, a placement cavity is formed in the middle position of the fixing frame, and a plurality of auxiliary cavities are formed between the outer wall of the fixing frame and the inner wall of the drying box. According to the vacuum drying device for pharmacy, the airflow movement effect is improved through the change of the width in the vertical direction, connecting holes of the rhombus structures of the fixing frame are matched, then airflow around medicine on a supporting plate generates flow speed change and direction change, and the contact effect of the airflow with the medicine is improved through irregular collision, so that the actual vacuum drying completeness and drying efficiency of the medicine are improved.

Description

technical field [0001] The invention relates to the technical field of pharmacy, in particular to a vacuum drying device for pharmacy. Background technique [0002] Pharmaceutical engineering is a processing activity intersecting chemistry, biology, pharmacy (Chinese medicine) and engineering. In the process of pharmaceutical production and processing, it is often necessary to dry the finished drug or the intermediate of the drug. Nowadays, the drug is often dried by vacuum drying. Operation. [0003] The vacuum drying operation of drugs is a drying method in which the material is placed under negative pressure conditions, and the boiling point under the negative pressure state is reached by heating appropriately, or the material is solidified by cooling to dry the material through the melting point. Put the medicine in the tray and place it in the drying chamber, and cooperate with the vacuum equipment to draw negative pressure in the chamber where the medicine is placed t...
