Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of tea drying, in particular to a tea natural drying turning machine. Background Art
[0002] Tea drying is an important step in the primary processing of tea. It mainly evaporates the moisture of tea through heat, thus forming the unique sensory quality and stable quality characteristics of tea. There are three main purposes of tea drying. The first is to use high temperature to stop the activity of enzymes. The second is to further evaporate the moisture so that the moisture content of tea is controlled within a certain range, usually within 13%. The third is to further improve the aroma of tea. In the process of tea drying, it can be carried out by drying, baking and roasting. Different drying methods will have different effects on the taste and aroma of tea. Therefore, a tea natural drying turning machine will be used when drying tea.
[0003] In the process of natural drying of tea leaves, it is often necessary to place the tea leaves in the atmosphere. Long-term placement will cause external foreign matter to mix into the tea leaves, and in the drying process, the tea leaves need to be turned over to fully dry them. Turning over will inevitably cause some tea leaves to break, produce residues and other foreign matter mixed together, and reduce the quality of the tea leaves. For this reason, we provide a tea leaf natural drying turning machine to solve the above problems. Utility Model Content

[0015] 1. The utility model is provided with a telescopic rod, a first rotating block, a second rotating block, a first rotating shaft, a blocking plate and a clamping column. After the tea leaves are dried in the drying frame, the tea leaves can enter the screening mechanism.

Finally, the elasticity of the screen is utilized to vibrate the screen surface by the vibration motor, so that the tea leaves bounce repeatedly, thereby avoiding clogging of the screen and increasing the efficiency of impurity filtration.
