Miniaturized extracting concentrating machine set and formulation production technique thereof

Abstract

The invention discloses a miniaturized extracting and concentrating unit and its preparation production process. The concentrating tank, extracting tank and liquid receiving tank are sequentially arranged side by side on a support, and the concentrating tank (1) and the extracting tank (2) pass through a pipeline (8 ) is connected, and is connected with the condenser through another pipeline (9), and a liquid suction pump (21) and a pipeline filter (20) are connected in sequence between the pipeline (8) and the bottom of the extraction tank, and its cooling A vacuum converter (7) is housed between the device (4) and the extraction tank, and a vacuum pump (16) is connected to the upper cavity of the vacuum converter. Its production process is: negative pressure extraction, negative pressure concentration, negative pressure reflux treatment and repeated circulation can be performed on Chinese herbal medicines until the active ingredients of the extract in the extraction tank are extracted, and then all the extract is sucked into the concentration tank to continue concentration. Until the concentrate in the concentration tank meets the requirements. The invention has the advantages of compact structure, small occupied space, energy-saving, high-efficiency, scientific and reasonable preparation process, and effectively improves the quality and extraction efficiency of the pharmaceutical preparation.

Description

1. Technical field [0001] The invention relates to an extraction and concentration equipment mainly used for the preparation of Chinese herbal medicinal materials - an extraction and concentration unit and a preparation production process thereof. 2. Background technology [0002] At present, the extraction and concentration units for Chinese herbal medicine preparations all adopt the preparation production process of normal pressure extraction, normal pressure reflux, and negative pressure concentration. The extraction tanks, concentration tanks, condensers and other facilities are separated by a large distance, and the production occupies a large space. 1. The operation is inconvenient, resulting in higher input costs; the production process consumes more energy, and the temperature during extraction is higher, which affects the retention and extraction of active ingredients of the drug. 3. Contents of the invention [0003] The object of the present invention is to over...
