Abstract
A method of using a sequence control system in combination with a spray system for applying a liquid, such as cooking oil, to a surface of a pan carried by a conveyor. The controller, which is a microprocessor based unit, is connected to spray nozzles adapted for projecting atomized droplets of liquid between charged electrodes in a timed sequence to cause the charged droplets to be attracted to and impinge against partial areas of a grounded pan surface to form a continuous substantially uniform film of liquid on the surface.
