Miniaturization extracting concentrating machine group and high-efficiency type preparation production technique thereof

Abstract

The invention discloses a miniature extraction and concentration unit and a preparation producing process thereof. The unit comprises a concentration tank, an extraction tank and an accumulation groove are arranged on a support in sequence, the concentration tank (1) and the extraction tank (2) are communicated through a pipe (8), the concentration tank is communicated with a condenser through another pipe (9), a liquid pump (21) and a pipe filter (20) are connected between the pipe (8) and the bottom of the extraction tank in sequence, a vacuum converter (7) is arranged between a condenser (4) and the extraction tank, the upper cavity of the vacuum converter is connected with a vacuum pump (16). The producing process is as follows: subpressure extraction, subpressure concentration, subpressure refluxing treatment and repeated cycle can be carried on for Chinese herbal medical materials until the effective components of the extracting liquid inside the extraction tank can be extracted completely, then the extracting liquid is absorbed into the concentration tank for continuous concentration until the concentrating liquid inside the concentration tank meets the requirements. The extraction and concentration unit of the invention is characterized by the compact structure, the small space being taken up, the preparation process of the invention has the advantages of saving energy and having high efficiency, being scientific and reasonable, and effectively improving the quality of pharmaceutical preparations and extraction efficiency.

Description

1. Technical field [0001] The invention relates to an equipment extracting and concentrating unit mainly used for extracting and concentrating Chinese herbal medicine preparations 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 overcome the above-mention...
