Problems solved by technology

Traditional Chinese medicine extraction methods include decoction method, dipping method, reflux method, percolation method, improved gelatin method, etc., but the traditional method has many shortcomings: 1) The decoction method loses more active ingredients, especially water-insoluble components; 2) The organic solvent may interact with the active ingredients during the extraction process, making it lose its original effectiveness; 3) The extraction yield is low, the extraction time is long, and the process is cumbersome; 4) Traditional Chinese medicine manufacturers often use multi-functional extraction tanks to directly feed and extract , because the conventional multifunctional tank cannot keep the solvent around the material at a certain concentration difference during the extraction process, the extraction efficiency is low, and the discharged medicinal residues generally have 1-2 times the medicinal liquid, which is easy to cause certain waste
The filter includes a filter screen and a two-position filter tank. This solid-liquid separation device only separates by filtration, and the separation efficiency is low, and the separation effect is poor, so it cannot be applied to the separation of different types of traditional Chinese medicines.
[0012] In addition, the existing technology also uses ceramic membranes for solid-liquid separation, which are mainly used in preparations such as traditional Chinese medicine injections that require extremely high clarity or active ingredient purity, but for traditional Chinese medicine formula granules or general solid oral preparations of traditional Chinese medicine, ceramic Membrane separation will cause problems such as large interception loss of active ingredients, incomplete prevention and control of membrane fouling, and low production efficiency.
[0013] However, the above-mentioned solid-liquid separation devices all adopt a simple solid-liquid separation method, the separation efficiency is low, and the separation effect is poor, and there are clear requirements for the type and nature of the traditional Chinese medicine to be separated. For the separation of precious and thin Chinese medicine extracts, Due to the high price of raw materials and the different viscosity, solid content, and impurity properties of the extract, it is difficult to use the above-mentioned general solid-liquid separation equipment

Embodiment 1

[0097] This embodiment relates to a method for extracting and separating ginseng. its use figure 1 The shown automatic extraction and separation device for traditional Chinese medicine performs automatic extraction and separation.

[0098] (1) Feeding:

[0099] Pretreat the ginseng slices, cutting or crushing to a particle size of <1cm;

[0100] Move 160KG of ginseng slices with a particle size of 3 Add 2400L of solvent into the dynamic extraction tank, and when the amount of solvent reaches the preset process setting value, put the ginseng slices into the extraction tank T-1 from the feeding port.

[0101] (2) Dynamic extraction:

[0102] After the feeding is completed, the steam regulating valve will be opened automatically so that steam will flow into the heating jacket of the extraction tank to heat the ginseng slices and water in the tank; while the heating jacket T-N3 of the extraction tank is heating, the The thermometer in the extraction tank at the bottom of the ...

Embodiment 2

[0110] This embodiment relates to the method for extracting and separating red ginseng. It also uses figure 1 The shown automatic extraction and separation device for traditional Chinese medicine.

[0111] (1) Feeding:

[0112] Pretreating the red ginseng, cutting or crushing the red ginseng until the particle size is less than 1cm;
