Abstract: The dryer includes in its programmable control circuit a microprocessor to which are connected at least a temperature sensor, a static pressure sensor, a motor revolution sensor, a ion generator, a resistor battery with its selector switches in series, and the respective power circuits of the motor and the air heater aforesaid, in which, in order to optimize the processing route, said microprocessor, after the dryer is turned on and the operating values of parameters, establishes the initial operating configuration at 50% of the value thereof, and then defines continuously, in terms of the ordinary data base, the constant functional conditions, and responds to electric, thermal and mechanical discrepancies being involved with its corrective stabilization, recording, signaling and information by means of a display.
