[0030] Working principle:

[0031] (1) Pre-sorting stage: White tea raw materials slide into the rotating outer cylinder between the partition plates through the feeding chute. When the outer cylinder carries the tea leaves through the magnetic zone of the inner cylinder, the iron filings are attracted to the cylinder wall by the magnet; when it continues to rotate to the non-magnetic zone, the magnetic attraction disappears, the iron filings fall off by gravity and are discharged through the second discharge port.

[0032] (2) Light impurity removal stage: During the process of the tea falling from the magnetic zone to the first discharge port, the impurity removal fan blows the light impurities toward the discharge port and discharges them; the clean tea falls to the feed end of the conveyor belt through the first discharge port.

[0033] (3) Spreading and conveying: After the tea leaves on the conveyor belt are limited by the enclosure, they are spread evenly by the spreading brush, which makes it easy for manual sorting.

[0034] (4) Collection stage: The sorted finished tea leaves are sent into the storage box by the conveyor belt; the debris picked out by hand is put into the holding tank.
