ABSTRACT:
The invention relates to a cooking device including a vessel for heating a cooking substance. The cooking substance is divided between a heating zone, a transition zone, and a cold zone. A first heating element is used to heat the cooking substance in the heating zone, and a transition zone heating device is used to heat the cooking substance in the transition zone. The transition zone heating device may be a pump for introducing a mixing medium into the cooking substance in the transition zone whereby the cooking substance in the heating zone mixes with the cooking substance in the transition zone. The mixing medium may be air, whereby the cooking substance in the heating zone is turbulently mixed with the cooking substance in the transition zone. The mixing medium also may be a portion of the cooking substance withdrawn by the pump from the transition zone and then reintroduced to the transition zone, thereby creating turbulence in the transition zone. The transition zone heating device may also be a second heating element. A method for operating a cooking device includes a vessel for heating a cooking substance. The cooking substance is divided between a heating zone, a transition zone, and a cold zone. The method comprises the steps of heating the cooking substance in the heating zone to a predetermined temperature and mixing the cooking substance in the transition zone with the cooking substance in the heating zone, thereby creating turbulence within the cooking substance in the transition zone. The turbulence is created by introducing air into the cook substance in the transition zone or by withdrawing a portion of the cooking substance from the transition zone and reintroducing the portion to the transition zone.
