Embodiment 1

[0012] Please refer to the attached figure 1 Connect the transformer 1 with the power plug 3 of the rice cooker 2, one end of the anti-oxidation and anti-corrosion silicone tube 4 is connected with the electric cooker, and the other end is connected with the condenser tube 5; the anti-oxidation and anti-corrosion silicone tube adopts a horizontal folded tube; A curved glass guide tube is installed at the end of the spherical condenser tube and inserted into the receiving bottle.

[0013] Therefore, when controlling the voltage of the transformer, the temperature inside the rice cooker can be controlled to reach the boiling point of the organic solvent. The vapor of the organic solvent becomes liquid due to the condensation of the condensation pipe, and the condensation pipe is installed horizontally and obliquely downward. It can directly flow into the receiving bottle along with the condensing pipe and the curved pipe, and play the role of recovering the organic solvent. Sin...

Embodiment 2

[0015] Please refer to the attached figure 2 Connect the transformer 1 to the power plug 3 of the rice cooker 2, one end of the anti-oxidation and anti-corrosion silicone tube 4 is connected to the electric cooker, and the other end is connected to the condenser tube 5; the anti-oxidation and anti-corrosion silicone tube is a vertical tube.

[0016] In order to prove more strongly that this device can speed up the extraction efficiency of Chinese herbal medicine components and save the use of organic solvents. Now use the extraction of traditional Chinese medicine ginseng extract as an illustration. Put 0.5 kg of traditional Chinese medicine ginseng dry product into this device, add 1 kg of 95% ethanol, heat at 70 ° C for 8 hours, and then filter and recover the ethanol to obtain 0.1 kg of extract. Usually, in the process of extracting 0.5 kg of ginseng, 3 kg of 95% ethanol is needed, soaked for three days, and about 0.08 kg of ginseng extract can be obtained. Therefore, the ...

Embodiment 3

[0018] See attached image 3 Connect the transformer 1 with the power plug 3 of the electric rice cooker 2, one end of the anti-oxidation and anti-corrosion silicone tube 4 is connected with the electric cooker, and the other end is connected with the condenser tube 5; A ground plug is installed at the lower end of the tube. The volatile oil components in the Chinese medicinal materials can be effectively extracted.

Abstract

The invention relates to a multifunctional Chinese medicinal crop component extraction separation and solvent recovery device belonging to a Chinese medicinal crop component extraction separation and solvent recovery device. A transformer is connected with an attaching plug of an electric cooker, and one end of an antioxidant corrosion-resistant silicon pipe is connected with the electric cooker and the other end is connected with a condenser pipe. The invention has novel structure and achieves the effect of controlling the temperature of the electric cooker by combining the transformer with the electric cooker. The device can be used for conveniently extracting Chinese medicinal crop components and can also be used for recovering and extracting the organic solvent used in the extraction and separation process.

Description

technical field [0001] The invention belongs to a device for extraction and separation of components of Chinese medicinal materials and a solvent recovery device. Background technique [0002] General Chinese medicine laboratories and research laboratories mainly use organic solvents to soak Chinese medicinal materials to obtain Chinese medicinal material extracts. The usual method used is to soak the Chinese herbal medicine in a large container, add an organic solvent, generally place it at room temperature for three days, then filter to obtain the filtrate, and reclaim to obtain the extract. Although this method is simple, it is time-consuming and requires a large amount of organic solvents to fully dissolve the components of Chinese herbal medicines in the organic solvents. [0003] Generally, the amount of organic solvent used in the extraction and separation of traditional Chinese medicine greatly increases the requirement for the capacity of the rotary steamer. In lab...
