Abstract :
In this paper a dryer is designed and implemented which is used in industry, agriculture, etc. The weight variable is a useful and important parameter for detecting product moisture. This dryer solves the lack of information about the dried problem that it is the major problem of other dryers. Therefore the intelligent dryer control system has three input variables (temperature, humidity and weight) and two outputs variables (heater and fan voltage). The dynamic model of the product (wet clothes, etc.) is unknown and nonlinear. Therefore a controller is designed and implemented based on fuzzy logic. The 660W heater increases the temperature and the fan discharges the moisturized air. System control works by ATMEGA micro-controller. After putting the product inside the dryer, the initial weight is measured and the heater is turned on. With heat production, the humidity of the product diminishes. This humidity is vented with the fan and the drying process is continued until the product is completely dried. Several tests are performed in the implemented system and system performance is evaluated carefully.
