The tea leaf drying and screening device comprises the following specific steps:

the method comprises the following steps: dried tea leaves are placed into the feed hopper 5, the first motor 7 drives the mixing rod 8 to rotate through a belt, then the mixing rod 8 stirs and mixes the tea leaves in the feed hopper 5, and the tea leaves enter the first end pipe 17 from a feeding hose 16 at the bottom of the feed hopper 5;

step two: after the tea leaves enter the first end pipe 17, the fourth motor 30 drives the rotating rod 31 at one end to rotate through a belt, so as to drive the base 13 to rotate on the upper part of the stabilizing seat 14, so that the screening device 11 circularly shakes around the stabilizing seat 14 in the loading box 3, and the tea leaves in the first end pipe 17 enter the filter screen cylinder 19 and the second end pipe 22; in the rotating process of the filter screen cylinder 19, the second motor 24 drives the stirring shaft 34 to rotate through the belt and the belt pulley 32, the stirring shaft 34 drives the plurality of external branches 35 to rotate in the rotating process, and the stirring shaft 34 and the branches 35 can mix and stir tea leaves in the filter screen cylinder 19 in the rotating process; the impurities and the broken powder in the tea fall downwards from the meshes of the filter screen cylinder 19;

step three: after the impurities, the crushed powder and the straws are screened out, the impurities, the crushed powder and the straws fall downwards from the filter screen cylinder 19; in the falling process, the second fan 37 operates to blow impurities, crushed powder and straws, and the impurities and crushed powder with light weight are blown into the dispersion holes 36 and then enter the storage tank 4 from the dispersion holes 36 to be collected; the straws with heavy mass fall downwards and finally fall to the bottom end inside the loading box 3, and the dust collection instruments inside the collection box 10 absorb and store the straws inside the loading box 3 inside the collection box 10 through the dust collection pipe 9;

step four: in the screening process of tea leaves, the first fan 23 blows air to the stirring shaft 34 and the branches 35, and heating wires in the stirring shaft 34 work to generate heat; hot air flows out from the stirring shaft 34 and the air outlet holes 33 inside the branches 35 to blow the tea leaves inside the filter screen cylinder 19; the tea leaves are fully mixed and stirred after being blown, and the heat in the air can dry the tea leaves; in the screening and drying process, the third motor 28 drives the driving gear 27 to rotate, and the driving gear 27 drives the driven gear 20 to rotate, so as to drive the filter screen cylinder 19 and the first end pipe 17 and the second end pipe 22 at the two ends to rotate;

step five: after the screening and drying are finished, the electromagnetic valve inside the second end pipe 22 is opened, the fourth motor 30 drives the filter screen cylinder 19 to rotate obliquely towards one end of the second end pipe 22, the tea leaves inside are discharged into the discharging hose 12 from the inside of the second end pipe 22, and then the tea leaves falling into the discharging opening 2 from the discharging hose 12 are discharged outwards.

And the fixing ring 40 can restrain the screen cylinder 19 and the both-end first end pipe 17 and the second end pipe 22 so as not to fall off during operation.

After the screening and drying are finished, the electromagnetic valve inside the second end pipe 22 is opened, and the fourth motor 30 drives the filter screen cylinder 19 to rotate obliquely towards one end of the second end pipe 22, so that the tea leaves inside are discharged into the discharging hose 12 from the inside of the second end pipe 22, and then are discharged outwards from the discharging outlet 2 of the discharging hose 12.

The discharge hose 12 and the feeding hose 16 do not influence the rotation of the screening device 11, tea leaves can be normally fed and discharged, and the tea leaf circulation efficiency is high. And the end of the discharge hose 12 is free to be removed from the interior of the second end tube 22. During installation, one end of the discharge hose 12 is inserted into the second end tube 22, and after insertion, the magnet layer 38 is bonded to the inner wall of the second end tube 22, so that friction is increased, and the discharge hose is not easy to detach during use. Meanwhile, the anti-slip sleeve 39 fills the gap, so that tea leaves cannot enter the gap in use, and the anti-slip sleeve 39 can further increase the friction force between the second end pipe 22 and the discharge hose 12, so that the connection is firmer.
