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 pr

Embodiment 1

[0042] The method of using the traditional Chinese medicine percolation process control system is as follows:

[0043] (1) Set each process setting value on the control unit;

[0044] (2) Add Chinese herbal medicines in the percolation tank 2, open the solvent tank outlet valve 7 and add solvent to the percolation tank 2;

[0045] (3) The radar liquid level gauge 9 monitors the height difference between the liquid level of the percolation tank and the medicinal material surface. When reaching the process setting value, close the solvent tank outlet valve 7 and start timing. When the soaking time reaches the process setting value, Open the solvent tank outlet valve 7, open the percolation tank outlet valve 10;

[0046](4) Observe the height difference between the liquid level on the radar liquid level gauge 9 and the medicinal material surface, and when the height difference between the percolation solvent liquid level and the medicinal material surface in the percolation tank...

[0049] Control method of Panax notoginseng percolation process

[0050] (1) Get the net decoction pieces of Radix Notoginseng, cross 20 mesh sieves after pulverizing, get Radix Notoginseng powder, get two parts of Radix Notoginseng powder respectively, each 100kg, carry out Radix Notoginseng percolation according to traditional method and the method of the present invention respectively;

[0051] (2) Set each process setting value on the control unit:

[0052] The high liquid level of the solvent tank is 80%, and the low liquid level is 20%; the height difference between the liquid level and the medicinal material level in the percolation tank is 20-30cm; the soaking time is 3 hours;

[0053] (3) Add notoginseng powder in the percolation tank 2, open the solvent tank outlet valve 7 and add the percolation solvent to the percolation tank 2; the percolation solvent is 75% ethanol; the addition of the percolation solvent is 800L; The percolation volume is 700L; the percolation r...

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...
