Large scale drying of wheat is done in a ________________ dryer?
Correct answer: B. Spouted bed
- A. Fluidised bed
- B. Spouted bed
- C. Tray
- D. Vacuum rotary
Explanation
Spouted-bed dryers are widely used for large-scale drying of grains such as wheat because they provide vigorous solids circulation and good gas-solid contact. Tray and vacuum rotary dryers are less suitable for this high-throughput grain duty.
