High-efficient tea winnowing machine convenient to adjust

Abstract

The invention discloses a high-efficient tea winnowing machine convenient to adjust, which comprises rack and a winnowing drum. The upper part of the rack is welded with the horizontally arranged winnowing drum; a plurality of support legs are uniformly distributed on the lower surface of the rack; a control cabinet is arranged on one side of the rack; a plurality of rotating wheels are uniformly arranged on the upper surface of the rack; electric heating wire meshes wind the peripheries of the rotating wheels; a plurality of discharge holes are formed in the upper part of the rack; a discharge hole is located between each two adjacent rotating wheels. According to the high-efficient tea winnowing machine convenient to adjust provided by the invention, a feed polarizing film is arranged under a feed inlet and is matched with a screen mesh, so that tea leaves can be shaken, impurities can be promoted to be separated efficiently, and the feed inlet can be prevented from being blocked; the rotating wheels are adopted to be matched with the electric heating wire meshes, so that the tea leaves slide down from the rotating wheels, and the impact is relieved; a miniature fan on an air outlet strip forms negative pressure above the winnowing drum, so that the tea leaves can fall farther, and more accurate grade classification is facilitated; the control cabinet controls the overall operation parameters, so that the machine can be conveniently adjusted according to the characteristics of different tea leaves.

Description

technical field [0001] The invention relates to the technical field of tea processing machinery, in particular to a conveniently adjustable high-efficiency tea winnowing machine. Background technique [0002] After the tea is picked from the mountain, there are many impurities such as sand, soil, green and yellow floating leaves, and even after the tea preparation is basically completed, there may be impurities such as dust and broken tea. The tea winnowing machine is the main processing of the tea refining plant. One of the equipment is used to classify and classify the tea according to the weight and size of the tea, and at the same time use the wind to remove sand, dust, green and yellow floating leaves, etc. in the tea. The tea winnowing machine in the prior art is difficult to grasp the impact of the tea. The force and drop have a certain impact on the refined production of tea. After sorting, there is a lot of dust on the tea, which seriously affects the quality of the...

Problems solved by technology

[0002] After the tea leaves are picked from the mountains, there are many impurities such as sand, soil, and green and yellow floating leaves. Even after the tea preparation is basically completed, there may be impurities such as dust and broken tea. The tea winnowing machine is the main processing of the tea refining plant. One of the equipments is used to classify and classify the tea according to the weight and size of the tea, and at the same time use the wind to remove sand, dust, green and yellow floating leaves, etc. in the tea. It is difficult for the tea winnowing machine in the prior art to grasp the impact of the tea. The strength and drop have a certain impact on the tea refining process. There is a lot of dust on the sorted tea leaves, which seriously affects the quality of the tea leaves. There are also problems such as unclear grading and inability to control the humidity of the tea leaves.
