Abstract

The invention relates to a device and a method for automatic feeding and discharging for alcohol precipitation in traditional Chinese medicine extraction. The device comprises an alcohol precipitationtank, a stirrer, and a pipeline and a valve which are connected with the alcohol precipitation tank, and the device further comprises an optical interfacial instrument, a motor, a discharging insertion tube and a control system; and the motor is arranged at one side of the alcohol precipitation tank, the lower end of the motor is connected with the discharging insertion tube, and one end of the discharging insertion tube is inserted into the alcohol precipitation tank. The device and the method have the following advantages: the alcohol precipitation tank can be effectively cleaned through in-situ cleaning to avoid cross-contamination, so the production process meets GMP standards; the optical interfacial instrument is used to effectively identify an irregular liquid-solid interface in the alcohol precipitation tank, so the problem of reagent wastes caused by precisou inaccurate artificial judgment of the solid-liquid interface is solved, and the production efficiency is effectively improved; and the feeding and discharging in alcohol precipitation are controlled by the control system, and automatic feeding and discharging make an operator not required in the alcohol precipitationworkshop section place, so automation and unmanning of the alcohol precipitation section are achieved, and the extraction efficiency of a liquid reagent is improved.

Description

technical field [0001] The invention relates to the technical field of traditional Chinese medicine extraction technology, in particular to a device and method for automatic feeding and discharging of traditional Chinese medicine extraction and alcohol precipitation. Background technique [0002] Extraction of traditional Chinese medicine is a vital part of traditional Chinese medicine production, and it is also a bottleneck restricting the industrialization of traditional Chinese medicine. In the production of traditional Chinese medicine extraction, the degree of automation of the alcohol precipitation section will be an important factor in the automation of traditional Chinese medicine extraction. [0003] At present, many traditional Chinese medicine extraction factories have realized the automation of the feeding section, concentration section and drying section, but the automatic feeding and discharging of the alcohol precipitation section has not been broken through a...
