Abstract
A deep fat frying system has heating elements controlled by triacs operated in the zero switching mode by a programmed digital processor. The triacs are switched, and thus power is delivered to the heating elements, at a rate substantially faster than the thermal cycle of the heating elements to create a constant or uniform temperature on the surface of the heating elements, which avoids temperature fluctuations, particularly excessive peak temperatures, in the heating elements that scorch fat in contact with the elements and that cause temperatures of the fat to overshoot a desired cooking set point temperature.
