Description

Technical Field

[0001] The utility model relates to the technical field of tea processing, in particular to a multi-layer wide-band self-propelled moisture regaining machine with small floor space and accurate moisture regain control. Background Art

[0002] Moisture regain is an important step in tea processing. After withering or straightening, the tea leaves are treated with high temperature to remove the grassy smell of the tea, evaporate the moisture, and make the leaves soft, which is convenient for subsequent shaping and aroma enhancement. Since the moisture distribution of the tea leaves after withering or straightening is still uneven, it needs to be spread out for a certain period of time to allow the moisture in the deep layer of the tea leaves to penetrate and diffuse to the surface, so as to achieve uniform moisture distribution inside and outside the tea leaves.

[0003] Existing rehumidification operations generally adopt a flat-laying structure and rely on natural ventilation to achieve rehumidification. The tea is spread over a large area and the thickness of the tea layer is uneven, which can easily cause poor ventilation inside the tea and heat fermentation, affecting the quality of the tea and subsequent processing. In addition, the number of tea leaves spread per unit area is also small. At the same time, the rehumidification process is easily affected by factors such as ambient temperature and wind direction, and cannot be precisely controlled, which restricts the improvement of tea production and tea quality, and cannot meet the requirements of large-scale assembly line production.
