Tea extracting solution extracting production line

Abstract

The invention provides a tea extracting solution extraction production line. The tea extracting solution extraction production line comprises a pulverizer, a storage bin, a first-stage countercurrentextractor, a filter press, a second-stage countercurrent extractor and a condensation tank. Two times of countercurrent extraction are adopted; a filter pressing procedure is added between two times of countercurrent extraction, the internal structure tissues of tea leaves are further damaged through extrusion, soluble substance components are more easily permeated and dissolved into a solvent, two units are used for extraction, the concentration difference of the extracting solution is further increased, and the yield of effective components reaches 90% or above.

Description

technical field [0001] The invention relates to the field of tea processing, in particular to a production line for extracting tea extract. Background technique [0002] With people's understanding of tea and health, the application field of tea is gradually expanding, and the tea deep processing technology is becoming more and more mature. In the process of extracting the effective components of tea leaves, many methods have been used in the prior art, the most common being the countercurrent extraction method. In the invention patent with application number CN201610049481.4, a tea polyphenol extraction and recycling method, a continuous countercurrent extraction method is proposed. The tea raw materials that have been picked, screened and pretreated are put into the extraction tank from the feeding device, and the scraper and spiral Driven by mechanical force, it moves along the tank, and after fully contacting with water for extraction, it is discharged after being squee...

AI Technical Summary

Problems solved by technology

This method only undergoes one countercurrent extraction, and the utilization rate of active ingredients in tea leaves is low
