ABSTRACT:
A liquid filtering apparatus, especially but not exclusively for cold milk, comprises a substantially cylindrical tubular casing having an inlet at one end for connection to a source of liquid to be filtered and an outlet at the other end for the filtered liquid, and a removable filter sock in the casing having an open end adjacent to the inlet and a closed end remote from the inlet. The internal diameter of the casing along at least a substantial part of the length of the casing is greater than the internal diameter of the casing adjacent to the inlet and the cross-sectional area of the filter sock decreases in the direction from the open end thereof to the closed end.
