Abstract
An automatic filtering system for filtering a cooking medium in a fryer, includes a frypot; a filter manifold having removable filter; a pump, that supplies cooking medium from the filter manifold to the frypot; a pressure sensor that senses a pressure of the cooking medium supplied by the pump; and a controlling mechanism that controls an operation of the pump in response to the sensed pressure data. The control mechanism halts the operation of the pump after sensing a drop in the pressure of the cooking medium pressure that is greater than or equal to a predetermined pressure drop threshold. The systems and methods of the invention provide automatic filtering that may reduce or eliminate an incorrect refilling operation after the filtering of cooking medium, so that the filtering process may be performed correctly each time.
