Abstract :
Two centrifugal air blowers are controlled in order to produce a constant airflow to maintain particles in suspension. In the present application peanuts are the subject of study to evaluate the potentiality of burning them with hot air. Two squirrel cage AC motors are controlled by only one microprocessor, although their power rating and air produced are different. A simple control loop maintains the plain peanuts in position, and turns them around
