Why isn't it intuitive that a device designed to evaporate water quickly gets hotter than the boiling point of water
But when it doesn't it takes a long ass time to dry, else we'd just line fry instead
And you're forgetting that water needs huge amounts of heat to evaporate. The heat capacity of plastic is rather small in comparison, so a machine capable of quickly vaporizing water also has the power to melt crappy thin plastic.
Modern dryers usually have a safety thermostat, but lint buildup is still a big fire hazard, so there are obviously temperatures in significant excess of boiling here.
