🔍 Key Concepts

• Air velocity and dehydration – how fast-moving air affects moisture loss from produce • Evaporator size and surface temperature – how a larger vs smaller evaporator changes how cold the coil surface must be • Temperature differential – how the difference between box temperature and evaporator temperature affects relative humidity in the chill box

💭 Think About

• Think about which combination will keep the air in the box at a higher relative humidity so the produce loses moisture more slowly. • Ask yourself: if the evaporator surface is very cold compared to the box (large temperature differential), what happens to the moisture in the air? • Consider whether fast or slow air circulation makes it easier or harder for the air to pick up and carry moisture away from the produce.

✅ Before You Answer

• Compare minimum vs maximum temperature differential and which one is more likely to keep the box air from becoming too dry. • Consider how a large evaporator vs a small evaporator affects how cold the evaporator surface must be to remove the same amount of heat. • Decide whether rapid or slow air circulation will remove moisture from the produce more quickly.

the air is circulated slowly over a large evaporator with a minimum temperature differential

the air is circulated slowly over a large evaporator with a maximum temperature differential

the air is circulated rapidly over a small evaporator with a maximum temperature differential
