Description

Technical Field

[0001] The present application relates to the technical field of white tea screening, and in particular to a multi-stage screening device for tea leaves. Background Art

[0002] Tea leaves, commonly known as tea, generally include the leaves and buds of the tea tree. White tea is a slightly fermented tea and a special treasure among Chinese teas. It is named because the finished tea is mostly buds, covered with white hairs, like silver and snow. It is one of the six major tea categories in China. White tea is not withered or rolled, but is only processed by sun drying or slow fire drying. It has the quality characteristics of complete buds and hairs, full of hairs, fresh hair fragrance, clear yellow-green soup color, and light and sweet taste. When processing white tea, it needs to be screened by screening equipment.

[0003] Chinese patent CN216261821U discloses a tea screening machine with different sieve holes. The patent discloses a technical solution with high tea screening efficiency, which solves the problem that the existing screening machine uses multiple layers of filter screens, which makes the screening efficiency of tea low, and also has the problems of inconvenient screen maintenance, complex structure and high manufacturing cost.

Therefore, a multi-stage tea screening device is proposed to solve the above problems. Utility Model Content
