Scope and Application
- Specifies requirements for heated-air mechanical grain dryer used for commercial purposes
- Excludes dryers for seeds
- Grain in this standard refers to palay and corn
Definitions
- Batch type mechanical grain dryer: holds grain in fixed volume in batches until desired moisture content is reached
- Continuous flow dryer: material being dried moves through drying chamber in a continuous stream without recirculation
Types of Grain Dryers
- Batch type:
- Flat bed type
- Recirculating type
- Vertical bin type
- Continuous flow:
- Concurrent flow type
- Counter-flow type
- Cross-flow type
- Mixing type
- Non-mixing type
