  • Patent number: 8813975
    Abstract: A screen media element having at least one apertured section. The apertured section has a first surface intended to receive and carry material to be screened, a second surface opposite the first surface, apertures extending from the first surface to the second surface and a circumferential surface connecting the first and second surfaces. The apertured section is surrounded by an outer frame along the circumferential surface, characterized in that the apertured section is made from ceramic material and that the outer frame is made of elastomeric material. The invention further relates to a method for manufacturing such a screen media element, and a screen comprising such screen media elements.

  • Patent number: 6647867
    Abstract: A pasteurizer (1) comprising an endless circulating transport conveyor (3) guided around deflection rolls (7, 8) and used for transporting through the pasteurizer (1) the products (18) to be pasteurized, and having a feed conveyor (5) and/or a discharge conveyor (9) oriented essentially transversely to the conveying direction of the transport conveyor (3) and having a smaller width than the transport conveyor (3), feed conveyor (5) and/or discharge conveyor to and away from the respective end face of the transport conveyor (3), and a transfer surface (4, 19) for bridging a distance between the conveying surface(s) of the feed conveyor (5) and/or of the discharge conveyor (9) and the conveying surface of the transport conveyor (3). The feed conveyor (5) and/or the discharge conveyor (9) is arranged so close to the respective end face of the transport conveyor (3) that the lateral boundary (K) thereof, which face the transport conveyor (3), is arranged above the contour of the respective deflection roll (7, 8).
