Abstract

The invention discloses a traditional Chinese medicine percolation process control system and control method, wherein the control system includes a control unit, a solvent tank, a percolation tank, and a percolation fluid buffer tank, and the control unit is used to control the solvent tank and the percolation tank. 1. Control the flow control elements in the percolation buffer tank, so as to realize the automatic control of the whole percolation process. Through the control system and the corresponding control method, the automatic control of the key process parameters of the percolation process of traditional Chinese medicine can be realized, the stability control of the quality of the extract solution in the percolation process can be controlled between batches, and the stability and uniformity of the final product can be guaranteed. And the modernization of traditional Chinese medicine provides new technologies.

Description

technical field [0001] The invention belongs to the field of traditional Chinese medicine pharmacy, and in particular relates to a control system and a control method for controlling the percolation process of traditional Chinese medicine. Background technique [0002] The traditional Chinese medicine percolation method is one of the extraction methods of traditional Chinese medicine. It is to put the crushed medicinal materials in the percolation tank. After soaking for a period of time, the solvent tank at the upper end continuously adds the extraction solvent to the percolation tank, and the extraction solvent permeates through the medicinal material layer. It flows downward, and the lower end of the percolation tank continuously discharges liquid, which is the process of extracting the active ingredients in the Chinese medicinal materials. [0003] In terms of equipment, the percolation method requires special percolation equipment, and the tank body can be a cylinder, c...

Problems solved by technology

[0004] ①The versatility is not strong: except for percolation extraction, most of the percolation tanks have no other functions, and there are few types of traditional Chinese medicine preparations prepared by percolation. Once the equipment is put into use, it must be idle for a long time, causing a great waste of resources ;

[0006] ③Occupied space: In order to achieve a good percolation effect, the percolation tank body needs to have a larger height-to-diameter ratio, that is, the workshop where the percolation tank is installed requires a higher floor height

Space is allocated separately for the installation of percolation tanks with a low usage rate, which causes great waste in the use of GMP workshops;

[0007] ④Increased labor costs and error probability: The more types of equipment in the workshop, the more complex it is, the greater the number of personnel required, and the higher the requirements for training. On the other hand, the probability of errors in operating multiple types of equipment by one person is higher than that of operating one type of equipment , especially operating equipment that is not commonly used is more error-prone

[0009] ① High labor cost: Stir the medicinal materials during the infiltration process, and industrialized large-scale production is labor-intensive and costly;

[0010] ② Poor quality controllability: the uniformity of infiltration and mixing, and the exhaust effect after filling are mainly judged by experience, the process and product quality fluctuate greatly with the technical level of operators, and the quality controllability is poor

[0012] At present, in the percolation process of traditional Chinese medicine, most of the key process parameters are controlled by manual experience, which has large human error, low degree of automation, and high energy consumption, which cannot guarantee the stability and uniformity of product quality.
