Abstract

The invention discloses a high-differential-pressure cold extraction concentration unit. The unit comprises a soaking device, a differential-pressure extraction device, a solid-liquid separation device, a separation clarification device, a pre-concentration device, a re-concentration device and a drying device which are connected in sequence; the separation clarification device comprises a liquiddelivery pump, ceramic membranes, a separation cooler and a buffer tank; the ceramic membranes comprise a primary ceramic membrane arranged in front of the separation cooler and a secondary ceramic membrane connected at the back of the separation cooler; a liquid conveyed by the solid-liquid separation device sequentially passes through the primary ceramic membrane, the separation cooler, the secondary ceramic membrane and the buffer tank under the driving of the liquid delivery pump; the buffer tank comprises a water outlet which communicates with the primary ceramic membrane; and the ceramicmembrane comprises a water production opening which communicates with the pre-concentration device. When the high-differential-pressure cold extraction concentration unit provided by the invention isused for extraction, the extraction efficiency is high, the speed is high, and the obtained product is high in quality.

Description

technical field [0001] The invention relates to extraction and concentration equipment, in particular to a high-pressure differential cold extraction and concentration unit. Background technique [0002] At present, the Chinese patent with publication number CN2760537 discloses a biological substance extraction device, specifically a differential pressure extractor. It is an extraction device that uses pressure difference changes to promote the exchange of intracellular and extracellular solutions under low temperature conditions, especially a device for low temperature extraction through the conversion of vacuum-normal pressure-pressurization. The differential pressure extractor consists of extraction room, material receiving room, extraction liquid storage tank group, compressed air station, feeding port, agitator, solvent sprayer, condenser, chilled water station, solvent storage tank, condensation buffer tank, vacuum station, It is composed of tempering liquid station, ...
