Tea ingredients include catechins, cholesterin, caffeine, inositol, folic acid, pantothenic acid, which are beneficial to health. Tea beverages made from tea are one of the three major beverages in the world. Tea was first used as a sacrifice. Tea leaves are leathery, oblong or oval, and can be directly brewed with boiling water. Tea leaves need to be screened during the production process of black tea;
[0003] For this purpose, the China Patent Network has published a screening device for the production and processing of black tea, with the publication number CN216137644U, which includes a screening box, a material discharge box is arranged on the top of the screening box, a second motor is arranged on one side of the screening box, a second rotating shaft is arranged on the output end of the second motor, a rotating disk is arranged at one end of the second rotating shaft, a movable column is arranged on the surface of the rotating disk, and a second connecting plate is arranged at one end of the movable column. Thus, the second motor drives the rotating disk to rotate through the second rotating shaft, and the rotating disk drives the first connecting rod to move through the movable column and the second connecting plate, so that the first connecting rod drives the screening plate to move back and forth, so that the screening plate is used to screen and filter the black tea leaves, and the debris and impurities in the black tea leaves are filtered out, which saves the workers from screening and filtering the black tea leaves, increases the convenience of screening and filtering work, and improves the screening and filtering work of black tea leaves;
[0004] When filtering tea leaves, the above device controls the screening plate to move back and forth so that the tea leaves can be shaken up and down, thereby screening the tea leaves. However, during the screening process, the tea leaves will block the network card of the screening plate. During the cleaning process, the above device needs to be cleaned manually with a handheld brush. During the cleaning process, the brush cannot reach the mesh holes of the screening plate, resulting in low cleaning efficiency. Therefore, a screening device for black tea production and processing is proposed. Utility Model Content
