Embodiment Construction

[0036] Specific embodiments of the present invention will be described below with reference to the accompanying drawings.

[0037] refer to figure 1 , figure 2 with image 3 . A preparation process of high-purity tea polyphenols, comprising the following steps:

[0038] 1) crushing: crushing the tea leaves to be processed by the plant crusher 1 to obtain crushed tea;

[0039] 2) Water extraction: put the crushed tea and water into the ultrasonic extractor 2 at a ratio of 1:20 for extraction to obtain an extract;

[0040] 3) centrifugation: transport the extract to a centrifuge 8 for centrifugation to obtain a centrifuge;

[0041] 4) Fine filtration: transport the centrate to the membrane filtration device 3 for membrane filtration treatment to obtain clear liquid;

[0042] 5) Adsorption: mixing the clear liquid with a tea polyphenol adsorption resin, so that the tea polyphenol adsorption resin absorbs the tea polyphenols in the clear liquid; the tea polyphenol adsorptio...

Abstract

The invention discloses a preparation technology and a production line of high-purity tea polyphenol. The preparation technology comprises the following steps: crushing, water extraction, centrifugation, refined filtration, adsorption, ethanol elution, vacuum concentration, spray drying and the like. A tea polyphenol purification technique in the technology can be completed at normal temperature under normal pressure, so the preparation technology has the advantages of low energy consumption, less impurity dissolution, short extraction time and high tea polyphenol yield; and ethanol elution isadopted, so that the caffeine content is effectively reduced while the tea polyphenol is enriched.

Description

technical field [0001] The invention relates to the technical field of tea polyphenol preparation, in particular to a preparation process and production line of high-purity tea polyphenols. Background technique [0002] High-purity tea polyphenols are mainly used in the production of anti-tumor drugs, cardiovascular health drugs, anti-viral agents, anti-diabetic and obesity health drugs and other pharmaceutical fields. Tea polyphenols used as raw materials for medicines must be of high purity, especially the content of caffeine should be low, so as to reduce the excitatory effect of medicines on patients. [0003] The tea polyphenol products prepared in the prior art all have the problem of high caffeine content, and it is difficult to directly use them as pharmaceutical raw materials. Therefore, it is necessary to develop a technology capable of preparing high-purity tea polyphenol products. Contents of the invention [0004] The invention provides a preparation process ...
