Early-stage processing device for tea polyphenol extraction

Abstract

The invention discloses an early-stage processing device for tea polyphenol extraction. The early-stage processing device comprises a base and a material mixing mechanism, a box body is arranged on the upper surface of the base, a feeding port and a liquid inlet are formed in the left end and the right end of the top of the box body respectively, and a discharging port is formed in the bottom side of the box body; and the material mixing mechanism is arranged inside the box body, the material mixing mechanism comprises a motor arranged in the middle of the top of the box body, a rectangular plate is transversely arranged at a position, corresponding to the lower part of the motor, inside the box body, the rectangular plate is fixedly arranged at the top in the box body through a support, a main shaft is arranged at the output end of the motor, the main shaft penetrates through the rectangular plate, and the bottom end of the main shaft is perpendicularly arranged inside the box body. The early-stage processing device is ingenious in design, tea leaves in the box body are fully cleaned through matched connection of the main shaft, the rectangular plate, a gear, a gear ring, a rotating rod and a limiting plate, and the rotating rod can realize rotation while rotating around the rectangular plate.

Description

Technical field: [0001] The invention relates to the field of tea processing, in particular to a pre-processing device for extracting tea polyphenols. Background technique: [0002] Polyphenols are compounds found in plant foods with potential health-promoting effects. The antioxidant function of polyphenols can play a preventive role in these chronic diseases. Tea polyphenols are the general term for polyphenolic compounds in tea. Studies have shown that tea polyphenols have various physiological activities such as anti-oxidation, anti-cancer, anti-radiation, anti-aging, prevention of cardiovascular diseases, lowering blood sugar and blood lipids, etc. Therefore, tea polyphenols have broad application prospects in the fields of oil, food, medicine, cosmetics and beverages. [0003] When extracting tea polyphenols, there are various methods, such as solvent extraction, microwave-assisted extraction, biological enzyme extraction, etc. When extracting polyphenols, tea leave...

Problems solved by technology

[0003] When extracting tea polyphenols, there are various methods, such as solvent extraction, microwave-assisted extraction, biological enzyme extraction, etc. When extracting polyphenols, tea leaves need to be soaked and cleaned first , so as to achieve the effect of decontamination on the surface of tea leaves. When the existing tea leaves are pre-treated, the cleaning equipment simply uses clean water to wash the tea leaves and cannot remove the residual pollutants on the tea leaves, thus causing the tea leaves to remain dirty. more, its cleaning efficiency is low, and the equipment occupies a large area, which cannot meet the existing needs for tea cleaning. Therefore, it is urgent to design a pre-treatment device for tea polyphenol extraction to solve the above problems
