ABSTRACT:
A fabric dryer employs microwave energy and an auxiliary air convection heater to heat the moisture in the fabric to be dried and provides for control of the microwave energy so that no arcing of metal or other electrically conductive parts occurs as the fabric becomes dryer. The fabric dryer has a controller that receives input from sensors and uses that input to progressively decrease the energy output from the magnetrons in such a manner to prevent arcing of all metal and other electrically conductive materials associated with the fabric, while also controlling the auxiliary air convection heater and an exhaust air recirculator to compensate for the decreased magnetron energy output.
