Question 82Refrigeration/AC - QMED70% to pass
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?
AI Explanation
The correct answer is D) the air is circulated slowly over a large evaporator with a minimum temperature differential.
This is correct because slower air circulation over a larger evaporator surface area with a smaller temperature differential helps minimize the dehydration of produce in chill boxes. The larger surface area and lower temperature differential reduces the rate of moisture evaporation from the produce, preventing rapid dehydration.
The other options are incorrect because: A) rapid air circulation and small evaporator will increase dehydration; B) rapid air circulation with maximum temperature differential will also increase dehydration; and C) slow circulation over a large evaporator with maximum temperature differential will still result in higher dehydration rates.
