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. The stabilization of the ordinary operation conditions, both of the motor and of the heating 
resistor is achieved by means of the corresponding sensor, the information from which is channeled towards and from the respective speed and 
temperature control while the signaling and the information are carried out by connecting the respective control in turn to the corresponding VU meter and the equipment display. The recording of events receives directly the information from sensors and from speed and temperature controls, while from the aforesaid speed and temperature controls the information is sent back to the parameter status 
verification point.
