Traditional Chinese medicine extracting method and device

Abstract

The invention provides a traditional Chinese medicine extracting method and device. According to the traditional Chinese medicine extracting method, traditional Chinese medicine ingredients are efficiently extracted in a low intensity and high frequency extracting manner by controlling the temperature and pressure of extraction. The invention further provides the traditional Chinese medicine extracting device capable of realizing the extracting method. The traditional Chinese medicine extracting device comprises a connecting base, a high pressure adjustable metering pump and an instantaneous heater, wherein a detachable extraction cup is arranged at the bottom of the connecting base; a filtering part and at least one liquid outlet pipe are arranged at the bottom of the extraction cup; oneend of the high pressure adjustable metering pump is connected to a water source by a pipeline, and the other end of the high pressure adjustable metering pump is arranged on the connecting base by apipeline and is communicated with the extraction cup; the instantaneous heater acts on the pipeline between the high pressure adjustable metering pump and the connecting base. The device is simple tooperate, convenient in metering, timing and temperature control and small in size, so that the device can meet household requirements.

Description

technical field [0001] The invention relates to the field of traditional Chinese medicine extraction, in particular to a traditional Chinese medicine extraction method and device. Background technique [0002] At present, ordinary people still use traditional open fire medicine packs to directly boil traditional Chinese medicine. The boiling time is generally about two hours. The traditional decoction process has the following problems: (1) long-time boiling has nitrite Concentration is not good for health; (2) boiling above 100°C, the temperature of the bottom of the pot exceeds 150°C, when the traditional Chinese medicine is thick, it is easy to paste the bottom, resulting in a large amount of harmful substances; (3) the loss of active ingredients is serious, and the boiling When the drug temperature reaches above 80°C, the loss rate of the active ingredient is as high as 80%. [0003] Although there is a Chinese medicine decocting machine on the market, due to its large ...

Problems solved by technology

[0002] At present, ordinary people still use traditional open fire medicine packs to directly boil traditional Chinese medicine. The boiling time is generally about two hours. The traditional decoction process has the following problems: (1) long-time boiling has nitrite Concentration is not good for health; (2) boiling above 100°C, the temperature of the bottom of the pot exceeds 150°C, when the traditional Chinese medicine is thick, it is easy to paste the bottom, resulting in a large amount of harmful substances; (3) the loss of active ingredients is serious, and the boiling When the drug temperature reaches above 80°C, the loss rate of active ingredients is as high as 80%.

[0003] Although there are Chinese medicine decocting machines on the market, due to their large size, they are only widely used in traditional Chinese medicine hospitals and are rarely used in families.

On the other hand, the traditional Chinese medicine decocting machines currently available in the market only solve the time customization of traditional Chinese medicine boiling and the separation of medicinal residues and medicinal soup after boiling, and other problems have not been effectively solved.

[0004] At present, there are also commercially available traditional Chinese medicine extraction machines, which mainly meet the needs of traditional Chinese medicine factories to extract traditional Chinese medicine. The extraction process is complicated, and the equipment occupies a large area, which cannot meet the needs of household use. In addition, high temperature and high pressure are generally used for extraction, and the effectiveness of Chinese medicine ingredients is also limited. Guaranteed, resulting in reduced efficacy
