Adjustable filter holder assembly

摘要

A filter holder assembly for use with an oil filtering pan in a food fryer filtration system to filter a contaminated cooking oil is provided with an adjustable sealing ring so as to accommodate filters of different thicknesses such as filter pads and filter paper. In one self-adjusting embodiment, the sealing ring is configured for vertical movement by way of a pair of pins operatively connected to the sealing ring and that are movable vertically within a corresponding pair of slotted hinge members. When a filter pad is used with this embodiment, the pins are urged against the hinge members such that pressure is applied to the sealing ring to form a positive seal. Alternative embodiments create a positive seal when either a filter pad or filter paper is used.
