Intelligent automated control method for traditional Chinese medicine production

Abstract

The invention relates to a control method for a traditional Chinese medicine production process, in particular to an intelligent automated control method for the extraction and production process of a traditional Chinese medicine by adopting a water-extraction and alcohol-precipitation technique as well as a water-decoction and alcohol-extraction technique. In the method, the whole production process is respectively controlled by a plurality of control stations; industrial Ethernet is connected with an upper operator station; non-PROFIBUS (process field bus) instruments are utilized as the field instruments of which an analog input/output signal is 4-20mA and an on-off input/output signal is plus +24VDC; and all the instruments are provided with field indicators and are connected with actuating mechanisms such as a valve, a pump, a motor, various transmitters and the like so as to realize control and data management for the whole extraction and production process of the traditional Chinese medicine from feeding, extraction, concentration, removal of impurities, extract collection, ethanol recovery to dreg draining. Compared with the existing traditional Chinese medicine extraction and production technologies, the method provided by the invention has the advantages that extraction ratio of liquid medicine is improved by 13%, extraction ratio of volatile oil is improved by 30%, total energy consumption is reduced by 28%, and recovery rate of ethanol and the liquid medicine are increased by 35% and 25% respectively.

Description

technical field [0001] The invention relates to a method for controlling the production process of traditional Chinese medicine, in particular to an automatic intelligent control method for the production process of extracting traditional Chinese medicine. Background technique [0002] The production process of traditional Chinese medicine refers to the whole process from raw materials into production to product storage. It is mainly composed of extraction, concentration, impurity removal, ointment collection, preparation, packaging, storage and other processes. Extraction is one of the most critical links in the production process of traditional Chinese medicine. First, it directly affects the quality of traditional Chinese medicine preparations. The extraction of traditional Chinese medicine is a complex process of physical changes and chemical reactions, and it is a complex dynamic system with multiple variables, large disturbances, and nonlinearity. Every link in the ex...
