Description

Technical Field

[0001] The utility model relates to the technical field of tea withering machines, in particular to a leaf discharging device of a tea withering machine. Background Art

[0002] Tea, commonly known as tea, generally includes the leaves and buds of the tea tree. It is also known as tea, tea, tea, tea leaves, and tea leaves contain catechins, cholesterin, caffeine, inositol, folic acid, and pantothenic acid, which are beneficial to health. Tea beverages made from tea are one of the three major beverages in the world. During the production and processing of tea, a tea withering machine is required to wither the tea leaves.

[0003] After searching the Chinese patent "Tea Withering Machine", the announcement number is "CN207269775U". This patent places tea leaves from the feed inlet, completes withering from top to bottom, and then outputs from the discharge port. At this time, the tea leaves flip over from the discharge port and fall into the conveying device, which places the tea leaves into the feed inlet again for cyclic withering. During the conveying process, the tea leaves are flipped and withered again evenly, which ensures the quality of the tea leaves, reduces labor, and improves work efficiency. Compared with traditional machines, this utility model is smaller in size and can complete the withering of the tea leaves only through circulation. However, the device has a poor effect on spreading the tea leaves when withering, and it is not convenient to spread the tea leaves evenly for withering, which reduces the withering effect of the withering machine.

[0004] Therefore, a leaf discharging device of a tea withering machine is proposed to solve the above problems. Utility Model Content
