Abstract
An Improved Deep Fat Frying System is disclosed which utilities heating elements controlled by triacs operated in the zero voltage switching mode by a programmed digital processor which can be used in a deep fat fryer and operated in a manner to minimize the maximum surface temperatures of the heating element surfaces during all phases of operation. The triacs together with the programmed digital processor allows the fryer to be controlled in all modes of operation to advantageously reduce peak power demand at various times during the daily operating cycle, to minimize maximum temperature required for efficient heat transference to the oil, and to reduce temperature overshoot. A method of operation has also been disclosed by which the maximum power consumption of a battery of two or more of the units can be minimized by maintaining a low power heat up during melt cycle or initial warm up all the way to a set point temperature.
