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
[0013] However, none of the above-mentioned extraction and separation methods discloses the use of dynamic extraction tanks for extraction, nor does it disclose the use of three-stage separation devices for separation, and the effects and efficiencies of extraction and separation are relatively low

Embodiment 1

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

[0098] (1) Feeding:

[0099] Coix seed is pretreated, cut or crushed to a particle size of <0.2cm;

[0100] Move 200KG of coix seed with a particle size of 3 Add 2000L of solvent into the dynamic extraction tank, and when the amount of solvent reaches the preset process setting value, put coix seed 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 coix seed 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 body side detects the tempe...

Embodiment 2

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

[0111] (1) Feeding:

[0112] Pretreat ginger pinellia, cut or pulverize it until the particle size is less than 0.5cm;

[0113] Move 150KG ginger pinellia with a particle size of 3 1950L of solvent is added to the dynamic extraction tank, and when the amount of solvent reaches the preset process setting value, ginger pinellia is put into the extraction tank T-1 from the feeding port.

[0114] (2) Dynamic extraction:

[0115] 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 ginger pinellia 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 side detects th...

Abstract

The invention relates to an automatic extraction and separation method for starch traditional Chinese medicines. The method includes a solid-liquid separation step for an extracting solution obtainedby dynamic extraction, wherein the separation step sequentially utilizes a primary centrifuge or a slag remover, a filtering solid-liquid separator and a secondary centrifuge to preform combined solid-liquid separation on the extracting solution and medicine slags flowing out of a dynamic extraction tank. Three-stage solid-liquid separation equipment is adopted to preform continuous operation, filtering bottleneck and blockage cannot be generated, continuous production can be realized, the production efficiency is high, the cost is low, and the separated product has high light transmittance and less precipitation.

Description

technical field [0001] The invention relates to the technical field of traditional Chinese medicine production, in particular to an automatic extraction technology of traditional Chinese medicine. Background technique [0002] Extraction is the primary link and an important operation unit of traditional Chinese medicine production, and the quality of its process directly affects the quality of the product. 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 oft...
