Induction heating steel plate with RF induction heating equipment
Objective Heat steel plates on conveyor system in order to cook Welsh cakes.
Material Steel plate 760 x 440 x 10mm (29.9 x 17.3 x 0.4 in.)
Temperature 200 ºC (392 ºF)
Frequency 20 kHz
Equipment DW-MF-45kW induction heating system, equipped with a remote workhead containing one 1.3μF capacitor. An induction heating coil designed and developed specifically for this application.
Process A flat serpentine heating coil under the steel conveyor system heats the steel plate to a uniform temperature of 200 ºC (392 ºF) in approximately 3 minutes. The Welsh cakes are placed on the hot steel plate and cook for 1½ minutes. The conveyor moves the cakes off the coil where they are flipped. A second pass over the coil cooks the other side.
Results/Benefits Induction heating provides:
• Clean heat directed only to the steel plates. Minimal heat is radiated to the adjoining areas.
• Safe, comfortable working conditions for the operators
• Lower operating cost compared to gas-fired ovens.
Reduced cost to run air conditioning system because less heat is released into the working environment.
