AI Technical Summary

Technical Problem

Existing red ginseng extraction devices suffer from low extraction efficiency, discarded evaporated extracts, unextracted trace amounts of extract in the residue, and difficulty in removing residues, all of which lead to decreased extraction performance.

Method used

The vacuum treatment section recovers the extract through a first cooler, a cyclone tank, and a second cooler. The upper and lower stirring screws of the mixer are installed to improve the stirring efficiency. The residue is discharged using a conveying device. The residue is extracted in the residue extraction section by an extrusion plate and a rotary cutter. The vacuum in the chamber is maintained by a vacuum shield plate.

Benefits of technology

It improves the extraction performance and yield of the extract, enhances extraction efficiency, prevents safety accidents, quickly removes residues, reduces energy waste, and maintains vacuum.

Abstract

The present invention relates to a vacuum extractor for improving extraction performance by means of a vacuum processing unit, wherein the extraction performance is improved by recovering an extract contained in air sucked in when a vacuum is generated. The vacuum extractor includes: an extraction chamber that extracts an extract from a raw material through a solvent; a chamber heating unit for heating the extraction chamber with a heat medium to improve extraction performance by heating the raw material; and a vacuum processing unit that generates a vacuum in the extraction chamber to easily extract the extract from the raw material while recovering the extract contained in the sucked air by the vacuum pump, the vacuum processing unit including: a first cooler that sucks air by the vacuum pump to cool the air and recover the extract when the vacuum is generated in the extraction chamber; a cyclone tank generating a cyclone and recovering an extract contained in the air passing through the first cooler by the cyclone; a second cooler for re-cooling the extract contained in the air passing through the cyclone tank and recovering the extract; and a recovery tank for storing the extract recovered from the second cooler.
