Description

Technical Field

[0001] The utility model belongs to the technical field of tea screening and processing devices, in particular to a tea screening box. Background Art

[0002] During the tea preparation and processing, tea impurity screening is a very important step, which can directly affect the quality and taste of the final tea. After being picked from the tea garden, the tea leaves will undergo preliminary drying and withering to make them soft. In addition, they are screened to remove small branches, dead leaves, and even small insects contained in the tea leaves. The Chinese utility model patent application number CN202223459944.4 discloses a tea screening box for tea processing. One of the traditional screening methods is manual selection, which is slow but meticulous. The second method is mechanical screening, such as screening boxes, vibrating screens, air separators or electrostatic impurity removers. The screening boxes and vibrating screens use the same technical principle, using a vibrator to vibrate the screen to separate the tea leaves and impurities.

[0003] When the screening box is screening impurities in tea leaves, the screen in the screening box is in a horizontal or inclined state. During the screening process of tea leaves when the screen is in the horizontal or small inclined state, the tea leaves may be aggregated together and not completely dispersed, resulting in the aggregated tea leaves containing impurities that have not been screened out, and repeated screening is required. When screening tea leaves, there is a problem that there is no design to disperse the tea leaves on the screen. For this reason, the present application proposes a tea screening box.
