An ultrasonic and microwave extraction system for traditional Chinese medicinal materials

Abstract

The invention provides an ultrasonic wave and microwave extraction system equipped with a reflux unit and used for traditional Chinese medicinal materials. The ultrasonic wave and microwave extraction system comprises a second reflux unit. The second reflux unit has a taper drainage cover which is inserted into a sample solution device; the large end surface of the taper drainage cover covers a whole liquid level and is located at a position which is above the liquid level and closest to the upper end of the sample solution device, so all the gas produced during microwave heating can enter the taper drainage cover and form liquid through condensation under the action of the inner wall of the taper drainage cover, and the formed liquid flows back to a sample solution along the taper drainage cover, thereby reducing air pressure above the sample solution device and improving an ultrasonic vibration effect.

Description

Technical field

[0001] The invention relates to an ultrasonic and microwave extraction system for Chinese medicinal materials, belonging to the technical field of extraction of useful components of Chinese medicinal materials. Background technique

[0002] The natural active ingredients in plants or traditional Chinese medicine have broad application prospects in the fields of medicine, food, chemical industry, cosmetics, and feed. The preparation of traditional Chinese medicine extracts, liquid extracts or biologically active substances in the pharmaceutical industry and the preparation of plant-derived functional additives in the food, cosmetics, and feed industries require extraction equipment; in the field of chemical and chemical analysis, sample pretreatment or Processes such as sample preparation and chemical synthesis may also require digestion and extraction equipment or reactors.

[0003] Ultrasonic assisted extraction and microwave assisted extraction are emerging extra...
