Problems solved by technology

In recent years, the micronization technology of traditional Chinese medicine has been developed, which uses physical ultrafine pulverization technology to make the medicinal material fineness reach micron or nanometer level. The products obtained by this technology have low purity and uneven particle size distribution, and most of them are targeted at For a single medicinal material, the nanoscale particles are basically above 700 nanometers, and the product stability is not very ideal

[0044] Preparation of nano-scale powder raw materials of Liuwei Dihuang (pills, tablets).

[0045] Ingredients: Yam, Poria, Cornus officinalis, Alisma, Rehmannia glutinosa, Atractylodes macrocephala

[0046] 1. Liquid preparation:

[0047] 1. Soaking:

[0048] Equipment used: heatable microwave multifunctional extraction tank

[0049] Put the medicinal materials in the extraction tank, add the prepared 70-75% solvent ethanol into the extraction tank, completely immerse the raw materials, supply heat, heat the temperature in the tank to 50----60°C, and the pressure in the tank must not exceed 0.02Mpa. Turn off the heat and let stand for 12-14 hours.

[0050] 2. Extraction:

[0051] Equipment used: heatable microwave multifunctional extraction tank

[0052] Stand still for a specified time, supply heat, heat the temperature in the tank to 50--60°C, turn on the circulation pump and microwave generator, and circulate and extract for 10 minutes under heat preservation, then clos...

specific example 2

[0069] Preparation of nanoscale powder of Ganoderma lucidum:

[0070] 1. Liquid preparation:

[0071] 1. Soaking:

[0072] Equipment used: heatable microwave multifunctional extraction tank

[0073] Add drinking water to the extraction tank, submerge the raw materials completely, supply heat, heat the temperature inside the tank to 50----60°C, the pressure inside the tank should not exceed 0.02Mpa, turn off the heat supply, and let it stand for 12-14 hours.

[0074] 2. Extraction:

[0092] Preparation of Nanoscale Pearl Powder

[0093] 1. Liquid preparation:

[0094] 1. Dissolving:

[0095] Equipment used: heatable microwave multifunctional extraction tank

[0096] Add the prepared aqueous solution with a pH value of 3 into the extraction tank, completely immerse the raw materials, turn on the microwave generator, make it move at a speed of 2-3 billion times / second, and shake and dissolve until the raw materials are completely dissolved into a uniform liquid .

[0097] 2. Concentration:

[0098] Equipment used: low temperature decompression vacuum thin film evaporation concentration equipment

[0099] After transferring the completely dissolved liquid to about 100L in the evaporator, turn on the vacuum pump, start the vacuum system, open the steam valve, and start to concentrate. Control the steam flow rate to keep the temperature at 60±5°C. During the concentration process, the high-concentration and low-concentration ethanol are respectively sent ...
