Description

Technical Field

[0001] This utility model relates to the field of tea production technology, specifically to a wind separation device for tea production and processing. Background Technology

[0002] Tea is a famous beverage unique to China. There are many varieties of tea, and the quality of tea also varies greatly. During the tea processing, a wind classifier is needed to classify the tea leaves.

[0003] According to a Chinese patent publication number "CN213855621U", a tea screening and filtering device includes two support plates. Support columns are fixedly installed on the left and right sides of the bottom surface of each support plate. A box is fixedly installed on the top surface of the two support plates. A vibration device is fixedly installed on the lower left side of the box. The vibration device is located on the left side of the top surface of the two support plates. An inlet is opened on the top surface of the box, and an outlet is opened on the bottom surface. Tea leaves enter the box through the inlet and fall onto the surface of the sieve plate. Tea dust and stems on the surface of the tea leaves are screened and fall onto the surface of the filter plate. A rotating motor drives a connecting rod and a second bevel gear to rotate. The second bevel gear drives a first bevel gear and a round rod to rotate synchronously. When the round rod rotates, a square rod rotates through a sleeve. The brush bristles move with the square rod to perform a cleaning motion, which not only saves time and effort but also improves work efficiency.

[0004] However, although the device can push the dried tea leaves into the filter screen through the brush and filter the size of the tea leaves, the material of the tea leaves becomes brittle after drying. Therefore, as the brush continuously pushes the tea leaves, it will press the tea leaves onto the surface of the filter plate and cause them to break, thus affecting the quality of the finished tea product. Therefore, an air separation device for tea production and processing is proposed to solve the above-mentioned problems. Utility Model Content
