Description

Technical Field

[0001] The utility model relates to the technical field of tea processing, in particular to a tea air separator for quickly separating tea powder. Background Art

[0002] Tea, commonly known as tea, generally consists of the leaves and buds of the tea plant. During the tea production process, the quality of the tea leaves needs to be graded, and they are generally divided according to the degree of wholeness or fragmentation of the leaves of the same type.

[0003] After searching, the Chinese patent with publication number CN214766952U discloses a tea air separator for quickly separating broken tea leaves, including a machine body, a feed trough, a support plate, an air outlet frame, a controller, a power cord, a material collecting device, a bracket, a blower and an air duct. The feed trough is fixedly connected to the right part of the top of the machine body, and the feed trough is connected to the inside of the machine body. The left and right parts of the bottom end of the machine body are respectively fixedly connected to the support plate.

[0004] The device uses a weighing sensor to sense the amount of material in the barrel. When the weight reaches the standard, the controller controls the lifting mechanism to move downward to drive the trough plate and the barrel to move out, achieving the beneficial effect of facilitating the removal and placement of tea leaves by using an up and down lifting method.

[0005] However, the device still has the following problems. The device transmits a stable airflow to the interior of the machine body through the cooperation between the blower and the air duct, and separates the tea leaves from the powder through the airflow, so that the tea leaves fall into the material barrel and the powder moves to the air outlet frame. In actual use, simple airflow dispersion is difficult to separate the tea leaves from the leaf stems of the same mass, and further screening is required, which makes it difficult to effectively improve the efficiency of the device in screening tea leaves.
