Multifunctional efficient continuous cyclic extraction, modification and concentration equipment

Abstract

The invention discloses multifunctional efficient continuous cyclic extraction, modification and concentration equipment comprising an evaporation and concentration tank, an extraction tank and a cooler; the cooler is vertically arranged and comprises an inner cavity, and a first inlet and a first outlet which are connected with the inner cavity; the upper part of the inner cavity is connected with a vacuum pump; the first inlet of the cooler is connected with a first outlet of the extraction tank and a first outlet of the evaporation and concentration tank, the first outlet of the cooler is connected with a first inlet of the extraction tank through an air communicating vessel, a second outlet of the extraction tank is connected with a first inlet of the evaporation and concentration tankthrough the vacuum water pump, and therefore an internal circulation structure is formed. According to the invention, an internal circulation for continuous extraction of solvents can be formed.

Description

technical field [0001] The invention relates to the field of extraction and concentration, in particular to a multifunctional high-efficiency continuous circulation extraction modified concentration equipment. Background technique [0002] The traditional extraction equipment is to add a solvent, extract the material, discharge the solvent containing the extract and concentrate, then add fresh solvent for secondary or multiple extractions, and then concentrate. This process will use a large amount of solvent for extraction, and A large number of follow-up concentration work is also generated, and the traditional extraction equipment adds "pure" solvent once, but in the continuous extraction process, due to the gradual increase of the concentration of the extract, the concentration difference between the material and the extract gradually decreases, so the exudation of the material The degree of extraction gradually decreases and even tends to balance, so it exposes the short...

[0002] The traditional extraction equipment is to add solvent, after extracting the material, discharge the solvent containing the extract to concentrate, then add fresh solvent for secondary or multiple extractions, and then concentrate. This process will use a large amount of solvent for extraction, and A large number of follow-up concentration work is also generated, and the traditional extraction equipment adds "pure" solvent once, but in the continuous extraction process, due to the gradual increase of the concentration of the extract, the concentration difference between the material and the extract gradually decreases, so the exudation of the material The degree of extraction gradually decreases and even tends to balance, so it exposes the shortcomings of traditional extraction equipment with poor material extraction efficiency

The material residues extracted by traditional extraction equipment, through tracking and testing, will basically leave more active ingredients that have not been fully extracted. However, according to the process cost calculation, if re-extraction will result in an increase in product cost, that is to say, the process production cost It will be greater than the value of the produced extract, so there is a situation where materials containing more active ingredients are directly discarded, resulting in huge waste
