Complete equipment for continuous counter-current ultrasonic extraction

Abstract

The invention discloses complete equipment for continuous counter-current ultrasonic extraction, comprising a continuous counter-current ultrasonic extractor, a continuous residue drying machine, a continuous residue solvent evaporation recovering and drying machine, an extracting solution residue-liquid separator, a continuous automatic discharge filter and a dynamic circulating low-temperature evaporation concentrator, wherein the continuous counter-current ultrasonic extractor is sequentially connected with the extracting solution residue-liquid separator, the continuous automatic discharge filter, and the dynamic circulating low-temperature evaporation concentrator; a raw material is conveyed to the continuous counter-current ultrasonic extractor for extracting a liquid medicine by conveying equipment; the liquid medicine is input into the extracting solution residue-liquid separator for separating out the residue, then enters the continuous automatic discharge filter for further filtering out fine residue, enters the dynamic circulating low-temperature evaporation concentrator for evaporating and concentrating, so as to obtain concentrate. By adopting the complete equipment, the functions such as extracting, filtering, residue-liquid separating, concentrating, and recovering of solvent tail gas are organically combined together systematically; continuous operation and large-scale industrialization of all procedures are achieved; the maximization of the extracting efficiency and the minimization of the solvent dosage are also achieved.

Description

technical field [0001] The invention relates to plant extraction equipment, in particular to a complete set of equipment for continuous countercurrent ultrasonic extraction. Background technique [0002] The modernization of traditional Chinese medicine is being accelerated, and the field of herbal medicine will enter a period of rapid development. The plant extraction process should first consider improving the yield of active ingredients, shortening the leaching cycle, ensuring product quality and advanced operation; the concentration process should improve energy efficiency, and select appropriate concentration equipment to ensure drug efficacy and a suitable concentration ratio; alcohol precipitation The process should consider how to shorten the alcohol precipitation time, achieve the purpose of removing impurities and improve the utilization rate of equipment. [0003] The general plant extraction process can be divided into static intermittent type, dynamic intermitt...
