It is located on a standard walking platform enabling convenient operation of cleaner. A switchboard located under the platform is used to control cleaner, fan and conveyors. The grain is transported to cleaner by a screw conveyor. The cleaned grain is transported to treater by a gentle slow-running elevator. At the end of the line, the cleaned and treated grain is bagged and ready for shipment.
