Full-automatic discharging centrifugal machine and centrifugal method

The invention discloses a full-automatic discharging centrifugal machine. The full-automatic discharging centrifugal machine comprises a base, a shell and a rotary drum driven by a motor to rotate, wherein the rotary drum comprises a rotary drum bottom plate driven by the motor, a screen drum is fixedly installed on the periphery of the bottom of the rotary drum bottom plate, an inner container isfurther fixedly installed on the rotary drum bottom plate, the inner container is located inside the screen drum, a centrifugal cavity is formed between the inner container and the screen drum, a feeding opening is formed on the rotary drum bottom plate, a discharging opening is formed between the lower end of the inner container and the lower end of the screen drum, a plurality of discharging cover plates matched with one another are hinged to the lower end of the inner container, and when centrifugal force generated by rotation of the rotary drum is larger than the gravity of the discharging cover plates, the disch
