Note: Conveyor steel plate heating

Objective:

Heat steel plates on conveyor system in order to cook Welsh cakes.

End Product:

Welsh cakes

Equipment:

Ambrell 40 kW induction heating system, equipped with a remote workhead containing one 1.3 μF capacitor.
An induction heating coil designed and developed specifically for this application.

Materials:

Steel plate 760 x 440 x 10mm (29.9 x 17.3 x 0.4 in.) 

Temperature:

200 °C (392 °F)

Frequency:

87 kHz

Testing:

A flat serpentine heating coil under the steel conveyor system heats the steel plate to a uniform temperature of 200 °C (392 °F) 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.

Benefits:

  • 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.
