Embodiment Construction

[0017] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with specific embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0018] In this embodiment, two countercurrent extraction units are designed to form an extraction production line. The dried tea leaves are crushed into a suitable particle size, about 10-80 mesh, and then enter the turnover storage silo, and are fed into the countercurrent extraction machine through the quantitative mechanism. The tea is sprayed to make the tea sink into the hot water quickly; under the action of the spiral plate, it is pushed from one end to the other, and the solvent passes through the preheater, preheated to the process temperature, and flows quantitatively from the other end to this end. In this ...

Abstract

The invention provides a production method of a tea extracting solution. According to the invention, two continuously-arranged countercurrent extractors are used for two-stage countercurrent extraction, and dried tea leaves are subjected to crushing, first-stage extraction, filter pressing and second-stage extraction. According to the invention, two times of countercurrent extraction are adopted,a filter pressing process is added between the two times of countercurrent extraction, and the internal structure tissues of the tea leaves are further damaged by extrusion, so that soluble substancecomponents are easier to permeate and dissolve in a solvent. Two units are used for the extraction, so that the concentration difference of the extracted liquid is further increased, and the yield ofeffective components reaches 90% or above.

Description

technical field [0001] The invention relates to the field of tea processing, in particular to a production method of 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 squeezed in the...
