Abstract
An apparatus for removing grease from a compartmental grease trap that has water provided therewithin so that grease forms a layer atop the water in the trap. The apparatus has a mounting portion that is securable to the grease trap and a housing portion pivotally connected to the mounting portion. A filter media is then secured by the housing portion. The housing portion is preferably constructed from a framing structure and an inner structure. The framing structure has two sets of opposed sidewalls and a perforated or mesh bottom sheet that allows water to pass therethrough. The inner structure is separably secured to the framing structure, such as by pivotal connection and the filter media is preferably held between the inner structure and the framing structure. The inner structure is capable of being locked into position with respect to the framing structure by a locking device. The housing portion may be caused to pivot relative to the mounting portion such as by a linkage, preferably a solid rod, connected at one end to the housing portion and accessible at an opposite end by an operator.
