Occurrence of 'case hardening' during drying of a high moisture solid cake _______________ the drying rate?
Correct answer: B. Decreases
- A. Increases
- B. Decreases
- C. Does not affect
- D. Exponentially increases
Explanation
Case hardening forms a dry, relatively impermeable outer shell that resists the movement of internal moisture to the surface. This reduces the drying rate, especially during the later period of drying.
