Background

Tea leaves are originated in China, and the tea leaves are used as sacrificial offerings at the earliest time. However, the beverage is eaten by people in the late spring and autumn, is developed into a medicinal food in the middle of Western Han, is developed into a palace high-grade beverage in the later period of Western Han, and is popularized among people as a common beverage which is the thing after the West jin. The ancient site of tea leaves planted artificially in Tianlushan mountain of Yuyao, Zhejiang has been found to have a history of more than 6000 years. Tea drinking begins in china. The leatheroid is oblong or elliptical, can be directly soaked and drunk by boiled water, and is divided into six categories according to variety, manufacturing mode and product appearance. The tea can be spring tea, summer tea, autumn tea and winter tea according to the seasons. Various raw tea or refined tea is processed into tea, including scented tea, compressed tea, extracted tea, medicinal health tea, tea food, tea-containing beverage, etc. The tea contains catechin, cholestenone, caffeine, inositol, folic acid, pantothenic acid, etc., and can promote health. Tea beverage-tea is known as one of the three major beverages in the world.

Because the production process of the tea is extensive and unsanitary, the tea is often mixed with impurities such as dust, hair, particle fragments, withered branches and leaves and the like, and the tea products produced in the prior production place are unsanitary. Aiming at the removal of the impurities, manufacturers traditionally rent a large amount of manual work to pick the impurities, and because the degree of seriousness and the responsibility of workers are different, the impurity removal condition of the manually picked tea leaves is not ideal, the labor amount is large, and the cost of the manufacturers is high.

The invention is further provided with: the both ends of a net section of thick bamboo all are provided with rotates the connector, each rotate the connector all include the base, with pedestal connection just stretches into the arc support of the inside upper end of a net section of thick bamboo, each arc support all is connected with upper end open-ended arc wall, and each arc wall is inside all to be provided with a plurality of lubricated roller bearings.

Through adopting above-mentioned technical scheme, the fixed of a net section of thick bamboo position of being convenient for to and a net section of thick bamboo of being convenient for rotates.

Based on the structure, the invention also discloses a method for removing impurities from tea by using the impurity removing device for tea processing, which comprises the following steps:

s1, putting the tea leaves to be subjected to impurity removal into a feeding groove;

s2, the net cylinder rotates at a low speed, the suction pump works to enable the strip-shaped dust suction grooves to generate suction, the suction of the strip-shaped dust suction grooves which are gradually far away from the feeding groove is gradually reduced, tea leaves are sucked out from the strip-shaped discharge hole by the first strip-shaped dust suction groove and rotate along with the net cylinder, the hanging nails on the net cylinder hook thin strip-shaped impurities such as hairs and strings in the tea leaves so as to be wound on the net cylinder, the suction sensed by the tea leaves in the rotating process is gradually reduced until the tea leaves fall on the screen, and the lighter dead leaves and other impurities can be continuously sucked and rotate backwards until the tea leaves fall into the first dust receiving groove due to too small suction;

s3, the fallen tea leaves roll downwards on the screen mesh to the receiving groove, and the particle impurities pass through the screen mesh and fall into the second dust receiving groove to complete the primary impurity removal of the tea leaves.

Compared with the prior art, the invention has the following beneficial effects:

firstly, the tea leaf can be continuously sucked out of the strip-shaped discharge port through the suction force of the strip-shaped dust suction groove, and fine dust on the tea leaf can be effectively sucked away;

secondly, in the rotating process of the net barrel, the fine strip-shaped impurities such as hair, strings and the like in the tea leaves are hooked and wound on the net barrel through the hanging nails, so that the fine strip-shaped impurities in the tea leaves are effectively removed;

thirdly, during the tea leaves rotate along with the net cylinder, along with the gradual reduction of the suction force of the strip-shaped dust collection grooves, the lighter tea leaves firstly fall off, and the lighter dead leaves, feathers and the like continue to rotate until falling off in the first dust collection grooves, so that the lighter large impurities in the tea leaves are effectively removed.

Fourthly, after the fallen tea leaves are screened by the screen, the particle impurities pass through the screen and fall into the second dust collecting groove, and the heavier particle impurities in the tea leaves are effectively removed.
