Grain Handling System

Grain Silo Loading Section: Grains will be unloaded in the feed hopper manually. Grating is provided in the feed hopper to avoid large size impurities. Suction hood is provided on the feed hopper to extract dust generated during grain unloading. The material will be conveyed by screw conveyor to bucket elevator, which discharges the grain into precleaner. The precleaner is for size separation and cleaning of grain. Cleaned grains are conveyed to storage silo through bucket elevator and chain conveyor. A dust extraction system comprising of bag filter, centrifugal fan, rotary valve is provided this section. Bag filter separates dust, and clean air is discharged in the atmosphere. Pulse jet type cleaning mechanism is incorporated in the bag filter, which ensures the bags are cleaned at specified time interval. Grain silo capacity is arrived at based on no. of days storage.
