Embodiment 1

[0084] Automatic tea processing production line such as figure 1 As shown, the angle between the feeding conveyor belt and the horizontal direction is 12 degrees, the speed of the feeding conveyor belt is 0.5m / s, the speed of the collecting unit conveyor belt is 0.5m / s, and there are 4 debris removal rollers. The spacing is 51.5cm, the rotation speed is 250r / min, the surface of the roller is wrapped with adhesive cloth, and the distribution density of hooks on the adhesive cloth is 25 / cm 2 , the height of the hook is 2.5 mm, and the ratio of the width of the debris removal area to the width of the roller is 1:1. Use this production line to remove impurities in Pu-erh sun-dried green tea.

[0085] Two workers check the removal effect of soft and fluffy debris such as hair and woven bags beside the collection conveyor belt, and take the form of random inspection. If there are more than 3 debris in 30kg of raw materials, re-picking is required. The inspection result is: there i...

Embodiment 2

[0087] Automatic tea processing production line such as figure 1 As shown, the distribution density of adhesive cloth hooks is 25 pcs / cm 2 , the height of the hook is 3.5mm, and other parameters are the same as in Example 1.

[0088] Use this production line to remove impurities in Pu-erh sun-dried green tea.

[0089] Two workers check the removal effect of soft and fluffy debris such as hair and woven bags beside the collection conveyor belt, and take the form of random inspection. If there are more than 3 debris in 30kg of raw materials, re-picking is required. The inspection result is: there are 2 sundries in 30kg of raw materials, and the result meets the standard.

Embodiment 3

[0091] Automatic tea processing production line such as figure 1 As shown, the distribution density of pasting cloth hooks is 36 pcs / cm 2 , the height of the hook is 3.5mm, and other parameters are the same as in Example 1.

[0092] Use this production line to remove impurities in Pu-erh sun-dried green tea.

[0093] Two workers check the removal effect of soft and fluffy debris such as hair and woven bags beside the collection conveyor belt, and take the form of random inspection. If there are more than 3 debris in 30kg of raw materials, re-picking is required. The inspection result is: there are 3 sundries in the 30kg raw material, and the result meets the standard.

Abstract

The invention provides an automatic tea impurity removing device and a production line. The automatic tea impurity removing device comprises a gear motor and at least one roller capable of rotating around the axial direction of the roller, rotation of the roller is controlled by the gear motor, an impurity removing area is arranged on the surface of the roller, a plurality of hooks are distributed in the impurity removing area, the distribution density of the hooks is 25-36 hooks / cm < 2 >, and the height of the hook ranges from 2 mm to 4 mm. According to the automatic tea impurity removing device, light and soft impurities mixed in the tea leaves can be quickly and effectively removed, the loss of the number of the tea leaves or the reduction of the quality of the tea leaves cannot be caused, meanwhile, the picking cost can be greatly reduced, and the method is suitable for industrial production.

Description

technical field [0001] The invention belongs to the field of food production and processing, and in particular relates to a tea automatic sundry removing device and a production line. Background technique [0002] Sun-dried green tea is formed by drying in the sun after a certain processing technology. Due to the influence of regional conditions and personal living habits in some areas, there are many impurities in raw tea and various types, so it is necessary to remove these by picking steps. Impurities. [0003] In the picking process, most impurities can be removed through electrostatic, color sorting and other processes, but the effect of removing impurities such as hair and braids is poor. Therefore, for these impurities, the traditional removal method mainly uses both hands to hold the tea leaves higher than the head, and then let them fall freely, and observe whether they contain hair with the naked eye during the falling process. In order to remove such inclusions,...
