Air dehydrating ambient air temperature?
I would like to dehydrate fruits with an outdoor air drying rack in an arid climate:
What ambient air temperature is ideal for this? I've heard anything below 118°F is good for dehydrating. Is 100°F better or worse than, say, 80°F?

What are the roles of air temperature and movement in dehydration?
The dehydration rate constant was found to increase exponentially with air temperature and to decrease exponentially with air relative humidity.How does temperature affect drying rate?
Runs having higher temperatures result in lower drying time compared to runs having lower temperatures. Thus, an increase in drying temperature increases the amount of moisture removed at a certain time.How do temperature air movement and humidity affect drying?
The rate of evaporation is actually driven by the relative humidity to a greater degree than by temperature. But, in fact, the two are inter-related. As the temperature of air is increased, it can absorb more liquid and, therefore, the relative humidity is decreased. Lower relative humidity promotes faster drying.Chapter 21:The influence of ambient air saturation and temperature on drying results
