Development of a Grain Drying and Storage System for Bulk Facilities of Grain Custody Warehouse -Square Silo System-

곡물보관창고의 산물시설화를 위한 곡물 건조저장시설의 개발 -사각 사일로 시스템-

A basic proposal on the design of a grain drying and storage system was suggested for the bulk facilities of grain custody warehouses. A model square silo system was designed and developed on the basis of the proposal. A square silo system made of steel plate was developed with a stirring device, an automatic moisture meter and an auto-control system of PLC. Then, the developed square silo system was evaluated through drying experiments with rough rice. The square silo system could dry grains uniformly with a stirring device and an auto-control system regardless of grain depth. The developed square silo system can be well adapted for the bulk facilities of grain custody warehouses.
