In this episode of “How it’s Made”, find out how clothes dryers are manufactured. Video after the jump.
Most dryers consist of a rotating drum through which heated air is circulated. The hot air removes the moisture from the fabric through evaporation. The drum is rotated relatively slowly in order to create a tumbling effect. In most cases, the drum is belt-driven by an induction motor. Spin dryers use centrifugal force to extract water from clothes and are energy efficient
