Alcohol recovery concentration on-line detection device during the production process of traditional Chinese medicines, and control method of alcohol recovery concentration during the production process of traditional Chinese medicines

Abstract

The invention discloses an alcohol recovery concentration on-line detection device during the production process of traditional Chinese medicines, and a control method of alcohol recovery concentration during the production process of traditional Chinese medicines. The alcohol recovery concentration on-line detection device is characterized in that thermometers are each arranged in a rectifying still and on the top of a rectifying tower; a liquid outlet for a cooler is provided with a hydrops device; an on-line alcoholic strength meter is arranged at a pipeline below the hydrops device; a reflux regulating valve is arranged in a reflux pipeline; and an outlet regulating valve is arranged in an outlet pipeline. The control method comprises: utilizing the on-line alcoholic strength meter to monitor the concentration of the recovered alcohol in real time, and regulating the opening degree of the outlet regulating valve and the opening degree of the reflux regulating valve. Through the above mode, the alcohol recovery concentration on-line detection device and the control method are used in the alcohol recovery process, can realize real time control of the alcohol concentration during the alcohol recovery process and realize stable control of the concentration of the recovered alcohol, improve the automatic control level during the alcohol recovery process for production of traditional Chinese medicines and the homogeneity of the concentration among batches for the recovered alcohol, and provide a new technology for improvement of quality stabilization of traditional Chinese medicine products and modernization of traditional Chinese medicines.

Description

technical field [0001] The invention relates to the field of alcohol recovery technology in traditional Chinese medicine pharmacy, in particular to an online detection device and control method for alcohol recovery concentration in traditional Chinese medicine production. Background technique [0002] With the rapid development of traditional Chinese medicine in my country, alcohol is used as the main extraction solvent and purification solvent, and the consumption is increasing day by day. Therefore, reclaiming the discarded dilute alcohol and ensuring the quality of the recovered alcohol to make it meet the reuse standard for reuse are the main ways for the majority of traditional Chinese medicine pharmaceutical companies to reduce production costs and improve economic benefits. The alcohol recovery tower is composed of tower kettle, tower body, condenser, cooler, etc. Its working principle is to use the azeotropic point of alcohol-water (95.6:4.4, v / v) and the boiling poi...

AI Technical Summary

Problems solved by technology

[0003] At present, there are the following problems in the alcohol recovery process of the existing traditional Chinese medicine production in my country: low concentration of alcohol recovery, low recovery rate, high energy consumption; low degree of equipment automation, generally still using manual experience control, and the uniformity between batches is difficult to obtain Therefore, it is necessary to develop a method for controlling the recovery concentration of alcohol in traditional Chinese medicine production to achieve stable control of the recovery concentration of alcohol
