Roasted at a constant rotation speed to be baked evenly.

However, such grilled chicken is simply grilled chicken by heat sources such as gas, electricity, briquettes, firewood, etc. In order to cook deep inside the chicken meat, the strength of the heat source should be strong and baked for a long time.

Therefore, the consumption of fuel and electricity is increased, there is a limit to burn the outer surface of the chicken or the whole meat is hard and delicious and light cooking, especially thick breast meat has a flaw that is not eaten well. There was a drawback that can not be baked as a whole delicious.

As described above, conduction and convection are not suitable for current roasting as a necessary slow energy transfer method, and many roasters using the far-infrared radiation are currently commercialized.
