Problems solved by technology

The traditional extraction methods used in plant extracts, such as maceration, percolation, digestion, preparation of decoction and perfusate, etc., all have shortcomings of one kind or another and cannot meet the growing market demand
Especially for herbal extracts, the demand is also increasing. The extraction rate of common extraction methods is low and the cost is high, which will cause waste of raw materials and cannot achieve industrial scale extraction.

Abstract

The invention discloses a continuous industrial-scale microwave extraction method which comprises the following steps: mixing plant biomass with a solvent, performing microwave action in a 915 MHz continuous flow extractor, and continuously adding a mixture of the plant biomass and the solvent into the 915 MHz continuous flow extractor in the microwave action process to obtain a plant extract. According to the mode, the microwave effect is enhanced in the process, so that the processing time is greatly shortened, the extraction efficiency, selectivity and quality of the target extract are improved, the effects of reducing the cost and improving the yield are achieved, the energy consumption can be reduced, the material utilization rate can be improved, and the scale and complexity of production equipment are reduced; the production of wastes is reduced to the greatest extent, the production cost is greatly reduced, and the increasing requirements of herbal medicine nutrition medicine and food industry can be met by adopting a technology which is more effective and advanced than a traditional extraction method.

Description

technical field [0001] The invention relates to the technical field of plant extraction, in particular to a continuous industrial-scale microwave extraction method. Background technique [0002] Plant extracts have long been used by traditional physicians to provide health benefits and are suitable ingredients for the production of nutraceuticals and nutritional products. The traditional extraction methods used for plant extracts, such as maceration, percolation, digestion, preparation of decoction and perfusate, etc., all have shortcomings of one kind or another, and cannot meet the growing market demand. Especially for herbal extracts, the demand is also increasing. Common extraction methods have low extraction rates and high costs, which will cause waste of raw materials and cannot achieve industrial-scale extraction. Contents of the invention [0003] The technical problem mainly solved by the invention is to provide a continuous industrial-scale microwave extraction ...
