ABSTRACT:
This system controls the cooking time of foods such as french fried potatoes that are cooked in a medium, typically hot fat that may change in temperature during cooking. A platinum resistance temperature transducer senses the temperature of the medium and is connected to circuitry that produces a voltage indicative of the cooking rate of the food at the sensed temperature. This voltage controls the frequency of a train of cooking rate pulses that are counted, starting when cooking is begun. When a preset number of pulses have been counted, an indicator goes on to show that cooking is complete.
