Description

TECHNICAL FIELD

[0001] The utility model relates to tea pretreatment technical field, more specifically, it relates to a kind of tea polyphenol extraction with tea pretreatment device. BACKGROUND

[0002] In the existing tea polyphenol extraction technology, tea pretreatment device is the key link to ensure tea quality and extraction efficiency, and tea pretreatment usually includes stirring and drying steps, which are crucial to the final quality of tea and the extraction effect of tea polyphenol. However, the existing tea pretreatment device has certain limitations in design. First, these devices often cannot adjust the drying effect of multiple positions, which means that the temperature and humidity distribution during the drying process may not be uniform, affecting the quality of tea. Second, since it cannot be adjusted according to specific conditions, the operator cannot adjust the drying process according to the type, humidity, temperature and other parameters of tea, thus affecting the extraction effect of tea polyphenol and the overall quality of tea. Therefore, developing a tea pretreatment device that can adjust the drying effect of multiple positions is of great significance to improving the extraction efficiency of tea polyphenol and the quality of tea.

[0003] Specifically, during the drying process, the drying effect may vary due to factors such as tea thickness, humidity and temperature. If the drying device cannot adjust the drying effect of multiple positions, some tea may be too dry or too wet during the drying process, resulting in a decrease in tea quality. In addition, due to the unadjustable drying effect, the operator cannot adjust the drying process according to the specific conditions of tea, thus affecting the extraction effect of tea polyphenol.
