ABSTRACT:
A programmable multi-function feedback cooking apparatus senses the temperature of food substance or a liquid cooking inside a vessel. The analog voltage produced by a temperature transducer is translated into a digital signal and is used by a central processing means which automatically adjusts the amount of heat energy that is applied by the heat source to the cooking food substance. In preferred embodiments, the generating means is a conventional gas or electric stove, oven or microwave. The programmable electronic feedback cooking apparatus comprises a temperature transducer which is placed inside a cooking vessel, an analog-to-digital converter, a microprocessor unit, and a control panel. The apparatus includes in a preferred embodiment, a remote control feature whereby the operator may program the electronic feedback cooking apparatus from a remote location, using a telephone.
