June 2013: Reduction in drying time
Thread Content
When using air as the drying medium to dry heat-sensitive materials and the drying process is in its deceleration phase, the most effective measure to shorten the drying time is ( ). A. Increase the temperature of the drying medium. B. Increase the drying area and reduce the thickness of the material. C. Decrease the relative humidity of the drying medium. D. Increase the air flow velocity. This is a multiple-choice question, but I think only B should be the correct answer. Let’s discuss it together
Option D is also correct; it’s similar to how when we dry clothes on a windy day, they dry faster than on a calm day
The most effective measure is only [B]; the other methods are all acceptable.
