A device for auxiliary extraction of proanthocyanidins based on hydroelectric pulse method

Abstract

The invention discloses a procyanidine auxiliary extracting device based on an electrohydraulic pulse method. The procyanidine auxiliary extracting device comprises a discharge control unit, a treatment chamber, a metal filtering net, a macromolecular membrane, an extracting chamber and a drying chamber, wherein a pulse electric field generator in the treatment chamber is soaked into liquid in thetreatment chamber in the working process; the electrohydraulic pulse shock wave times and repeating frequency are set by regulating and controlling the discharge control unit; the shock waves act onthe grape seeds soaked into the liquid to form a mixed solution through the high-voltage pulse electric field and shock waves produced by the high-voltage pulse discharge, the mixed solution is filtered by the macromolecular membrane, the mixed solution containing an extracting object is extracted in the extracting chamber, and is dried under the vacuum condition, and finally the extracted productis purified. The procyanidine auxiliary extracting device has the characteristics that the shock waves produced by the high-voltage pulse discharge in the liquid act on the cells of the grape seeds;the structure is simple, the cost is low, the effect is obvious, the environment-friendly effect is realized, and the like; meanwhile, the problem of damage to the biological activity of the grape seeds and the procyanidine in the extracting process of the prior art is effectively solved.

Description

technical field [0001] The invention belongs to the fields of high-voltage technology, pulse power technology and the extraction of effective components of natural products such as proanthocyanidins, and more specifically relates to an auxiliary proanthocyanidin extraction device based on a hydroelectric pulse method. Background technique [0002] Proanthocyanidins are a kind of polyphenolic flavonoids commonly found in natural plants. The common extraction methods include organic solvent extraction, microwave extraction, aqueous enzymatic method and supercritical CO 2 method, AB-8 macroporous resin method, etc., the organic solvent extraction method is simple to operate, but the extraction time is long, the extraction efficiency is low, and there may be residual organic solvents, causing pollution to the product; the equipment required for supercritical extraction The price is expensive, the production cost is high, and it is still difficult to realize large-scale industria...
