Automation of drying duration and space between electrode of the ion wind drying

This study aims to perform automation of the drying duration and the distance between the electrodes of the ion wind drying with Plasma technology. The ion wind drying consists of 20 x 20 pin multi-ring concentric electrodes. As a central controller and data processor, an Arduino Mega 2560 microcontroller is used. In the space between the electrodes, the rotational motion of the four stepper motors becomes the vertical translational motion of the nuts and bolts. Drying duration is applied when the sample lies on the board above the conveyor and is exposed to ionizing wind. The duration controller uses a stepper motor linked to a timing belt and a conveyor pulley adjusted as its speed. The presence of the sample in the board moving with the conveyor is detected by the ultrasonic sensor. The results obtained a control system that can adjust the distance between the electrodes along 0 - 20 mm with 1 mm intervals and drying duration 0-40 minutes with 5 minutes intervals.
