The rework filter comprises an enclosed housing (12) with a feed inlet (16) for the product to be filtered, a discharge (20) for the filtered product, an outlet for the filtered residue and a filter insert (14) disposed between the feed inlet and the discharge, where the insert has a cylindrical filter wall through which the product flows in the radial direction from the inside out. A rotatable core element (30) is provided that is disposed coaxially in the filter insert. A defined annular chamber is designed between the core element and the filter wall.

A rotatable core element (30) is provided that is disposed coaxially in the filter insert. A defined annular chamber is designed between the core element and the filter wall. The core element is dimensioned such that the resultant annular chamber makes a constant flow of the product. A scraper is disposed on the outer periphery of the core element and scraps the inner surface of the filter. The core element rotates so that the residue is discharged. The filter insert comprises openings with a mesh fineness of 10-400 micometer. The total area formed by the openings corresponds to double of the cross-section of the feed inlet. The interior surface of the filter wall is processed by a cutting process and is seamless. The openings are mechanically produced in the filter wall or by laser radiation. The core element is equipped with a drive that ensures rotation of the core element in forward- and backward direction. The number of revolutions is adjustable in dependent of a pressure difference between the feed inlet and discharge. The core ele
