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 is not only a popular drink, but also carries rich historical and cultural connotations. From the origin, classification, and production process of tea to its far-reaching cultural influence, tasting tea is actually experiencing a long and profound cultural tradition.

[0003] The existing tea grading and screening devices basically use a screening cylinder and a driving motor to vibrate the screening cylinder to screen the tea. Chinese patent document CN220804360U discloses a tea grading and screening device. By providing a sleeve, a spring and a universal joint, during the use of the tea grading and screening device, due to the reaction force of the spring in the support block, the force can be given to the box body through the inner rod, and multiple groups of mechanisms can realize the placement of the box. Whenever the exciter is running, the inner rod adaptively retracts and contracts, and the spring adaptively deforms, the box body will be in an irregular swinging state, thereby driving the tea material on the screening net to shake, effectively improving the screening efficiency of the tea. By providing a sleeve, a spring and a universal joint, during the use of the tea grading and screening device, due to the reaction force of the spring in the support block, the force can be given to the box body through the inner rod, and multiple groups of mechanisms can be To realize the placement of the box, whenever the vibrator is running, the inner rod adaptively extends and retracts, the spring adaptively deforms, and the box shows an irregular swinging state, thereby driving the tea material on the screening net to shake, effectively improving the screening efficiency of the tea.
