Abstract

The invention discloses a method and an apparatus for extracting effective components of plants by ultrasonic cooperating with an electrostatic field. The apparatus for extracting effective components of plants by ultrasonic cooperating with an electrostatic field comprises an extraction tank, and is characterized in that is the extraction tank is a rinse tank type cylindrical sound reactor in which a central electrode is arranged, the anode and the cathode of a static generator are electrically connected with the central electrode through a control switch, and the grounded terminal of the static generator is electrically connected with the side wall of the extraction tank. The invention has the advantages of realizing extraction of polar components and nonpolar components, having high extraction rate, short period of extraction and low extraction temperature, avoiding using an entrainer or reducing the amount, and reducing the pollution of the residual of the extractive.

Description

technical field [0001] The invention relates to a technology for extracting active ingredients of plants, in particular to a method and a device for extracting active ingredients of plants in cooperation with ultrasound and an electrostatic field. Background technique [0002] The traditional methods for extracting active ingredients of plants mainly include: water decoction, solvent extraction and steam distillation, etc., which have the advantages of simple process and easy operation, but there are problems such as long extraction time, low extraction rate, and high energy consumption. In particular, the organic solvent extraction method also has disadvantages such as flammable and explosive hazards and solvent residues in the extract. The unique cavitation effect of ultrasonic waves propagating in liquid media, coupled with multipolar effects such as mechanical vibration, micro-jet, and micro-acoustic flow generated by ultrasonic waves, can destroy the cell walls of medic...
