Refrigeration systems using forced air circulation evaporators have a tendency to cause rapid dehydration of produce in chill boxes. Which of the following will minimize this dehydration?

Correct Answer: Option D — the air is circulated slowly over a large evaporator with a minimum temperature differential

Minimizing produce dehydration in shipboard chill boxes requires high relative humidity. Circulating air slowly over a large evaporator with a minimal temperature differential prevents excessive moisture condensation and freezing out of the air onto the coil surfaces.
