A Rice/Maize Elevator (also called a grain elevator or bucket elevator) is a machine used to lift and transport grains like rice or maize vertically from a lower level to a higher level in processing plants, storage facilities, or mills. It typically consists of a vertical casing, a series of buckets attached to a moving belt or chain, pulleys (or sprockets), a motor, and an inlet and outlet. The buckets are evenly spaced along the belt or chain and are designed to scoop up grain from the bottom section (boot) of the machine.

In operation, grain is fed into the bottom inlet, where the moving buckets pick it up as they pass through. The belt or chain, driven by an electric motor, carries the filled buckets upward inside the enclosed casing. When the buckets reach the top (head section), they discharge the grain by centrifugal force or gravity into a chute, which directs it to storage bins, processing machines, or packaging systems. The empty buckets then continue their cycle back down to pick up more grain. This system ensures efficient, continuous, and gentle handling of grains, minimizing damage and spillage while saving labor and time.
