Description

Technical Field

[0001] The utility model relates to the technical field of tea withering machines, in particular to an automatic circulation type tea withering machine. Background Art

[0002] Withering, also known as "withering carving", is the name of the tea making process. The fresh leaves are spread out in a certain thickness and dried in the sun to make them wilt. During the withering process, the fresh leaves undergo a series of changes: the moisture content is reduced, the leaves become soft from being brittle and hard, and are easy to be rolled into strips. The activity of the enzymes contained in the leaves is enhanced, which promotes the decomposition and transformation of fresh leaf components such as starch, protein, and insoluble protopectin, and produces glucose, amino acids and other effective substances that are beneficial to the quality of the tea. Withering requires suitable temperature, humidity and air circulation. Traditional withering methods include sunlight withering, indoor withering, and There are two methods: natural withering and compound withering that combines the above two methods. However, the quality of the finished product and the time required for natural withering depend on weather changes, and it is impossible to maintain a stable output of finished products and time control. Tea leaves are usually laid on a flat plate or a clamping net. The degree of air drying on the upper and lower sides of the former is uneven, and it needs to be turned over, which wastes time. At the same time, the tea leaves are easily blown away by the wind. In order to improve the withering efficiency, mechanical drying is usually carried out. However, the drying efficiency of the drying device is different for tea leaves at different distances, which can easily lead to withering time differences in the same batch, affecting the recovery efficiency.
