Description

Technical Field

[0001] The utility model belongs to the technical field of tea processing, in particular to a tumbling screen for sun-drying tea leaves. Background Art

[0002] Tea processing is a complex process that transforms fresh tea leaves into drinkable products, involving multiple steps. Sun-drying tea leaves is an important step in the primary processing of tea. The purpose of sun-drying tea leaves is to evaporate the moisture in the fresh tea leaves moderately through the exposure to natural sunlight, promote the transformation of the substances contained in the tea leaves, and thus form the unique aroma and taste of the tea leaves. In the process of sun-drying tea leaves, it is necessary to use a tea sun-drying tumbler to sieve the tea leaves, which can effectively ensure the efficiency of sun-drying tea leaves.

[0003] The existing tumbler screen for sun-drying tea leaves is constructed by pouring the tea leaves to be sun-dried into a drum inside the tumbler screen, and then using a motor to drive the drum to rotate. The rotation of the drum drives the tea leaves inside to be tumbled, thereby achieving tumbling and screening of the tea leaves. However, in actual use, since the amount of tea leaves that need to be sun-dried at one time is large, some of the tea leaves will be concentrated at the bottom end of the drum under the action of gravity during the tumbler screening process. The tea leaves concentrated at the bottom end of the drum are difficult to be exposed to sunlight, resulting in poor sun-drying effect. Utility Model Content

[0004] In view of this, the present invention addresses the deficiencies of the existing technology and provides a tumbling screen for sun-drying tea leaves.
