Output power maximization for double layer heating of impeller and container of mixer

In this paper, the fast heating up impeller and container directly by induction heating is proposed. Simultaneous heating of the impeller and the container leads to the homogeneous and rapid heating for the chemical reaction. To show the feasibility of proposed method, the induction heating of the double layer of the stainless steel plates are investigated. Experimental results show the good feasibility of the simultaneous heating. To know the input power to the impeller, the equivalent coil is used for the measurement. The simple equivalent circuit is proposed and the calculation from it shows good coincidence to the dependency to the SUS plate thickness. Both the experimental results and the calculated results show that there is the optimum thickness of the impeller to maximize the output power. The thickness of the middle plate also affects the performance of the impeller heating. The experimental results show that the thinner is better. Finally, realistic heating experiments show the good temperature rise.
