Large scale drying of sugar is done in a _______________ dryer?
Correct answer: C. Rotary
- A. Spouted bed
- B. Tray
- C. Rotary
- D. Truck
Explanation
Rotary dryers are suited to continuous, large-scale drying of free-flowing solids such as sugar because they provide high throughput and repeated solids movement. Tray and truck dryers are generally used for smaller batches.
