Sticky material can be dried in a ________________ dryer ?
Correct answer: A. Tray
- A. Tray
- B. Rotary
- C. Fluidised bed
- D. None of these
Explanation
Tray dryers can handle sticky or pasty materials because the material can remain on stationary trays without needing continuous mixing or fluidisation. Fluidised-bed and rotary dryers require better-flowing solids.
