The elevator cups lifted the seed to 6.1 m and then delivered the seed to the hopper of an air-screen cleaner with grader through the delivery pipe. The hopper of the air-screen cleaner
was 4.2 m from the ground level. From there, the seed was passed over a gravity separator
whose hopper was 2.0 m from ground level and was finally collected in a jute bag held at ground
level.
