摘要： My invention is a portable filtration and treatment apparatus, comprising a tank, a filtering mechanism immersed in the tank (holding cooking oil), a treating mechanism preferably situated external to the tank, a pump, and a discharge. The pump draws liquid (cooking oil) from the tank through the filtering mechanism, through the treating mechanism, and back into the tank or into a cooking fryer by way of the discharge. The tank includes a moving device which allows for the portability of the apparatus. The filtering mechanism comprises a wire mesh envelope, including at least one wire mesh filter screen for filtering the cooking oil, an insert disposed within the wire mesh envelope supporting the wire mesh envelope and providing fluid communication therethrough, and a frame which holds the wire mesh envelope and the insert together. The treating mechanism is a container and is provided with an inlet and an outlet, a selectively removably attached top, and a flow baffle. The container top is sealingly attached to the container in order to effectuate a vacuum within the container upon the activation of the pump. Treating material is disposed in pouches within the treating mechanism. Cooking oil is pumped through the treating mechanism thereby contacting the treating material disposed within the treating mechanism. Treating material comprises any material, such as activated carbon, which upon contact with the cooking oil can extend the usable life of the cooking oil.

摘要： A device and method for continuously and concurrently filtering and treating cooking oil used while frying food in a fryer with cooking oil therein is disclosed, including a filtering mechanism and a treating mechanism. The mechanisms are mechanically interrelated and are both disposed internally of said fryer. The mechanisms include an external wire mesh envelope, including at least one wire mesh filter screen for filtering the cooking oil, and an inner frame disposed within said external wire mesh envelope. The inner frame comprises the outline of a generally rectangular shape with two fingers extending into the rectangular frame from midway along each of two of the frame opposing side walls, said fingers and inner frame supporting the wire mesh envelope. The mechanisms further comprise first and second caps threadedly connected to each other through the wire mesh envelope and the inner frame. The caps provide fluid communication to a suction pump. The inner frame and the interior walls of the wire mesh envelope define compartments to retain treating materials which extend the usable life of the cooking oil. The suction pump draws cooking oil from outside the wire mesh envelope, through the inner frame, through the compartments and treating material, and through the first and second caps.

摘要： There is provided a portable liquid filtering apparatus for filtering liquid used in a container, such as cooking oil in deep fat fryers. The apparatus includes a mounting bracket that attaches to a portion of the container. The mounting bracket supports a liquid pump. A filter assembly including at least one filter element is removably disposed in the container, and is connected to the pump inlet by a suction tube. The pump draws the liquid through the filter element and suction tube and propels it into a discharge tube connected to the pump outlet. The discharge tube discharges the filtered liquid back into the container for reuse. The mounting bracket is adjustable for attachment to various sized containers. The suction tube and the discharge tube are shaped to conform generally to the shape of the container.
