Description

Technical Field

[0001] The utility model relates to the technical field of tea production, in particular to a tea powder screening device. Background Art

[0002] Tea leaves, commonly known as tea, generally include the leaves and buds of the tea tree. Other names include tea, tea, tea, tea. Tea ingredients include 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. Tea originated in China. Tea was first used as a sacrifice. It was processed from various raw teas or refined teas to form re-processed tea, including scented tea, compressed tea, extracted tea, medicinal health tea, tea food, tea-containing beverages, etc.

[0003] In the prior art, a Chinese utility model with publication number CN218014148U discloses a device for separating tea leaves from tea powder, comprising a bottom bracket, a screening box, a primary discharge port, a secondary discharge port, a vibration motor, a feeding hopper and a screening plate; the screening box is a square box structure, and the lower end of the screening box is fixedly connected to the upper end of the bottom bracket; the primary discharge port is fixedly connected to the middle of the left side panel of the screening box; the secondary discharge port is fixedly connected to the lower end of the left end panel of the screening box; the vibration motor is fixedly connected to the lower side of the right end of the screening box; the lower end of the feeding hopper is fixedly connected to the middle of the upper end of the screening box; the screening plate is a square plate structure, and the screening plate is slidably connected to the inner right end of the screening box.

[0004] In the above technology, the staff first puts the tea leaves from the feeding hopper into the screening box. During the falling process of the tea leaves, the tea leaves are blown by the wind of the separation fan. On the one hand, the tea leaves are dispersed and fall to the bottom under the blowing of the wind, preventing the tea leaves from gathering together, so that the tea leaves can be screened more cleanly. On the other hand, the powder in the tea leaves flies to the right under the action of the wind, and the fine powder in the tea leaves can be separated from the tea leaves. However, when the tea leaves are stored, they are eroded by moisture, which increases the adsorption force between the tea leaves. Therefore, if the tea leaves cannot be dehumidified and dried when screening, the tea leaves will not be fully and thoroughly screened, resulting in poor effect after screening.
