Locally made equipment for teaching and research in agricultural engineering. Manual No.7. Grain drying rig

Abstract

This eprint provides information on the design and use of this equipment for teaching and research.

This manual, which is one of a series on locally made equipment for teaching and research in agricultural engineering and associated technologies, describes a rig for studying the air flow through and drying of grain by forced air circulation in a vertical bed. The rig is described and construction drawings are rovided; a parts list and sources of supply for purchased items are given. The use of the rig for air flow/pressure and grain drying drop experiments is described and the relevant theory is presented. It is not a rig for drying significant quantities of grain.
