Abstract
An oil fryer control system simultaneously controlling oil temperature and cooking time. A proportional, integral and derivative temperature control is used to maintain the oil temperature below and above a predetermined set point temperature. In addition, a cooking time control varies the cooking time within a predetermined range of temperature error as a function of a stored time-temperature relationship. The invention provides the capability of cooking different products having different cooking parameters in the same or different oil vats.
