Tea leaf separation system with antibacterial and moistureproof functions and separation method

The invention discloses an antibacterial and moistureproof tea leaf separation system and a separation method.The system comprises a conveying mechanism, a screening mechanism, a stem scraping mechanism and a discharging mechanism, the screening mechanism is fixedly arranged on the surface of the top of the conveying mechanism, and the upper surface of a box body on the conveying mechanism is fixedly connected with the lower surface of a shell on the screening mechanism; the stem scraping mechanism is movably arranged in the shell, and the discharging mechanism is fixedly arranged on the upper surface of the shell. A second motor drives a linkage shaft to rotate, so that a cam on the linkage shaft simultaneously drives a screening mechanism and a stem scraping mechanism to continuously reciprocate in a shell, tea leaves and tea stems are rapidly separated through rapid reciprocating movement, the air volume is controlled through an air blower, and the temperature is controlled; and hot air can be reasonably b
