Is rice truly a desiccant?

However, for something like an electrical device, it’s difficult to reach every wet nook and cranny by contact. The dry rice or other desiccant speeds the evaporation by keeping the air dry.

I still think that something like a desk fan blowing regular (air conditioned) room air on the device is going to be significantly more effective at removing moisture than any static “rice in a box” setup.
