Grain solids unable to pass through screen apertures are propelled in a helical pattern through the screen cylinder until being discharged through its open end, into a chute that funnels the dewatered solids into a plastic tote on a pallet below. When a tote is full with about 2,500 lb (1,136 kg) of the damp grain, a pallet truck replaces it with an empty tote. The full totes are stored in a holding area to be picked-up by a farmer.
