Improved tea spreading and cooling device

Technical Field

The invention relates to the technical field of tea processing equipment, in particular to an improved tea spreading and cooling device.

Background

Tea refers to the leaves and buds of tea trees, distinguished tea, cashew, tea, . Broadly refers to the leaves of evergreen bush tea tree which can be used for making tea, and the beverage made by these leaves, later extended to all herbal teas made by plant flowers, leaves, seeds, roots, such as chrysanthemum tea, etc.; "herb tea" and the like prepared by infusing various medicinal materials are also called Lei ya in Chinese literature. Some countries also have tea made from leaves of other plants such as fruit and vanilla, such as fruit tea "

Tea leaves are originated in China, and the tea leaves are used as sacrificial offerings at the earliest time. However, the beverage is eaten by people in the late spring and autumn, is developed into a medicinal food in the middle of Western Han, is developed into a palace high-grade beverage in the later period of Western Han, and is popularized among people as a common beverage which is the thing after the West jin. The ancient site of tea leaves planted artificially in Tianlushan mountain of Yuyao, Zhejiang has been found to have a history of more than 6000 years. Tea drinking begins in china.
