Description

Technical Field

[0001] The utility model relates to the technical field of tea processing equipment, in particular to a withering device for tea processing. Background Art

[0002] During the processing and preparation of tea, it is often necessary to wither. Through withering, on the one hand, part of the moisture of the tea can be evaporated, the tension of the tea cells can be reduced, the leaf stalks can be softened from brittle, and the toughness of the buds and leaves can be increased. On the other hand, the loss of water can cause a series of chemical changes in the substances contained in the tea tips, which are used to form the specific quality of the color, aroma and taste of the tea. During the whole withering process, the activity of enzymes contained in the fresh leaves is enhanced, which promotes the decomposition and transformation of fresh leaf components such as starch, protein and insoluble protopectin, and generates glucose, amino acids, soluble pectin and other effective substances that are beneficial to the quality of the finished tea. Polyphenols are also oxidized to varying degrees. In this process, a withering device for tea processing is often needed to assist. However, there are still some defects in its actual operation.

[0003] The withering device used in tea processing often requires manual work to spread the tea leaves on the withering trough and use natural wind for slow withering treatment, which results in low withering efficiency of the device and difficulty in regulating the automatic and uniform guidance of low-temperature hot air to the tea leaves to achieve withering treatment. Secondly, it is not easy to automatically spread the tea leaves, which results in a waste of human resources, low practicality, and is not suitable for long-term promotion. Utility Model Content
