Description

Technical Field

[0001] The utility model relates to the field of tea leaf withering devices, in particular to a tea leaf withering device for green tea production. Background Art

[0002] Green tea is one of the main types of tea in China. It refers to a drink made from new leaves or buds of tea trees that have not been fermented, but have been withered, shaped, and dried. The color of the finished product and the tea soup after brewing retain the green tone of fresh tea leaves. Drinking green tea regularly can prevent cancer, reduce fat and lose weight, and can also reduce the harm of nicotine to smokers.

[0003] The withering of green tea is a key process in green tea processing. It uses high temperature to release moisture from the leaves, inactivate enzyme activity, and cause certain chemical changes in the contents of fresh leaves, thus forming the quality characteristics of green tea. During the withering process, if the pot temperature is too low and the leaf temperature rises for too long, the tea polyphenols will undergo an enzymatic reaction, resulting in "red stems and red leaves". On the contrary, if the temperature is too high, more chlorophyll will be destroyed, resulting in yellowing of the leaves, and some even have burnt edges and spots, reducing the quality of green tea.

[0004] When withering green tea, the tea leaves need to be placed in a withering cylinder first. A stirring device is provided in the withering cylinder. A rotating plate for stirring the tea leaves is provided in the stirring device to loosen the accumulated tea leaves, which is beneficial to the withering of the tea leaves. However, when the tea leaves move in the withering cylinder, they only move through a plurality of rotating plates, which easily leads to a relatively single movement trajectory of the tea leaves. To a certain extent, this affects the withering of the tea leaves and slows down work efficiency.

[0005] Therefore, it is necessary to provide a new tea leaf withering device for green tea production to solve the above technical problems. Utility Model Content
