Description

Technical Field

[0001] The utility model relates to the technical field related to tea processing, in particular to a tea processing flattening device. Background Art

[0002] Tea refers to the leaves and buds of the tea tree. It generally refers to the leaves of the evergreen shrub tea tree that can be used to make tea, as well as beverages brewed from these leaves. Later, it was extended to all herbal teas brewed from plant flowers, leaves, seeds, and roots, such as "chrysanthemum tea"; "cold tea" brewed from various medicinal materials, etc., also known as Lei Ya in Chinese literature. Some countries also have tea brewed from other plant leaves such as fruits and herbs, such as "fruit tea". During the processing of tea leaves, a flattening device is needed to flatten them.

[0003] After searching, it is found that the typical flattening device in the prior art is disclosed in CN212212557U, which is a tea processing flattening device, including a base, a flattening mechanism installed on the top of the base, and a cleaning component installed on the outer wall of the flattening mechanism. The tea processing flattening device can drive the rotating rod to rotate clockwise through the operation of the motor, and the connecting rod rotates at the same time, prompting the compacting roller to rotate on the outer wall of the connecting rod and move with the rotating rod, so as to flatten the tea leaves on the top of the base, and clean the tea leaves stuck to the outer wall of the compacting roller through the cleaning component. The device can clean the tea leaves stuck to the outer wall of the compacting roller while flattening the tea leaves to avoid affecting the flattening effect.

[0004] To sum up, most of the existing flattening devices do not have the function of automatic flattening when in use, and need to be flattened manually. However, manual flattening makes it difficult to control the thickness of the tea leaves, resulting in inconsistent thickness of the tea leaves, causing poor quality of the processed tea leaves. At the same time, it does not have the function of pre-screening, which easily leads to uneven sizes of the flattened tea leaves, affecting the quality of the subsequent tea leaves. In view of the above problems, the existing equipment needs to be improved. Utility Model Content
