An apparatus for stir-frying discrete pieces or particles of one or more foodstuffs, the apparatus comprising a heated surface in the form of the interior surface of a portion of a substantially circular cylindrical body, stirring means comprising a helical body or screw 44, 45, 46 having an axis and arranged for rotation at least partly within and in close proximity to the heated surface such that rotation of the helical body transfers the discrete pieces along the cylindrical body substantially parallel to the axis such that the screw and heated surface form a screw conveyor, and scraping elements 32 arranged on the rim of the turns of the screw for scraping the heated surface when the screw rotates so as to remove any layer of material originating from the foodstuffs and adhering to the heated surface, each of the scraping elements comprising a first elongate body 35 made of a resilient material, preferably polyetheretherketone (PEEK), and having a substantially rectilinear scraping surface 36 for engaging and scraping the interior surface and a first 36 and a second 37 end portion, and a second elongate body 38 made of a resilient material, preferably PEEK, and having a third 39 and a fourth 40 end portion and having a first screw attachment portion 41 located between the third and fourth end portions, preferably equidistantly from the third and fourth end portions, wherein the first and second elongate bodies are interconnected at a point 43 located between the third end portion and the first screw attachment portion and at a point 43 between the fourth end portion and the first screw attachment portion in such a manner that the second body is spaced from the first body.
