Description

Technical Field

[0001] The utility model relates to the technical field of tea processing, in particular to a tea air separation and dust removal machine. Background Art

[0002] Air separation and dust removal is a highly efficient tea processing technology used to remove impurities and dust from tea leaves. This process uses wind power to effectively separate tea leaves from impurities due to differences in density and size. This technology also reduces the labor intensity of manual sorting and improves production efficiency, making it an indispensable step in modern tea processing. By precisely controlling wind force and screening speed, air separation and dust removal ensures tea purity and meets high tea quality standards.

[0003] However, wind separation and dust removal have high requirements for wind speed. When a large amount of tea leaves are blown by wind, they also need to be blown by wind carrying large mechanical potential energy to blow away the dust attached to the tea leaves. During this process, a lot of noise will occur in the factory area, so it is necessary to appropriately reduce the sound impact caused by the wind blowing.

[0004] Therefore, a tea air separation dust removal machine is proposed to solve or alleviate the above problems. Utility Model Content
