Abstract

This paper presents implementation and control of an induction dehydrator for food applications. The technique of induction heating is applied, for better efficiency and controllability of the system, compared with the conventional food drying method. The temperature is controlled by regulating the resonant current flowing in the induction coil through switching frequency adjusting. With proposed control strategy, the temperature can be controlled to constant at 55 degrees Celsius throughout the operation where the average system efficiency of 96.5% is achieved. ฉ 2019 IEEE.
