  • Patent number: 9096079
    Abstract: A media drying system removes a moistening liquid from a moistened medium, the moistening liquid having a moistening-liquid boiling point. A liquid-supply system provides a heating liquid. A liquid-heating system warms the heating liquid to a temperature greater than the moistening-liquid boiling point. A liquid-delivery system impinges the warmed heating liquid onto a surface of the moistened medium. Heat is thus transferred from the heating liquid to the moistening liquid, vaporizing the moistening liquid and removing it from the moistened medium.

  • Patent number: 8046934
    Abstract: The present invention concerns a convective system for a dryer installation for a passing web, more particularly paper. The convective system 7 is an assembly of an exterior casing 13 for suction of combustion products with opening 14 towards the web, with a first 15 and second 16 suction ducts sucking the combustion products into the convective system 7. The combustion products coming from the first suction duct 15 are guided through the exterior casing 13 to a mixing and blowing device 17. Cold air 18 is mixed in this mixing and blowing device 17 with the combustion products 19, resulting in a gas mixture with lower temperature 20. The convective system 7 also has an internal casing 21 inside the external casing 13. This internal casing 21 has at least one opening towards the web 22 and has also openings 34 allowing gas flow from the mixing device 17 to the internal casing 21 of said gas mixture 20.

  • Patent number: 8011115
    Abstract: A fiber-web machine dryer section has a drying group with single-wire draw so the drying wire (F) presses the web (W) against heated cylinder surfaces with the web (W) at the side of the outside curve of reversing cylinders (11) situated between drying cylinders (10, 12). A pocket space (T) is formed between two adjacent drying cylinders (10) and a reversing cylinder (11) situated between them, and the drying wire (F). A negative pressure component (20) placed in the pocket space (T) creates a pressure difference over the drying wire (F) and the web (W) for attaching the web (W) to the drying wire (F) so the cross-direction shrinkage of the web (W) is controllable. The wire tension (F) is maintained at a level help control cross-direction shrinkage of the web. The pocket space (T) is sealed by sealing members (25, 26) to maintain negative pressure in the pocket space.

  • Patent number: 7383641
    Abstract: A through air dryer (TAD) fabric having a composite configuration whereby side fabric portions made of a more resistant material are woven to the main body portion of the fabric. Side fabric portions that are not protected from the paper web, and therefore exposed to harsher environmental conditions than the portion of the fabric covered by the paper web, deteriorate faster. By replacing the side portions that are exposed to harsher environment with more resistant material, the TAD fabric will last longer.

  • Patent number: 7146748
    Abstract: The system for drying shopping carts dries a large number of wet shopping carts. The carts are loaded onto a conveyor belt. Side dryers located on either side of the conveyor belt initially dry the carts. The carts are passed under a freestanding arch having support columns situated on either side of the conveyor belt. The arch includes a number of overhead dryers. When the carts move under the arch, they are dried from above by the overhead dryers. Water dispelled from the shopping carts runs into a drainage system situated on the floor. Once the shopping carts are dried, the carts are unloaded from the conveyor belt and are removed from the housing.

  • Patent number: RE40123
    Abstract: A water-driven jet or venturi extraction means is used to remove, capture and cool the hot, highly humid air created within commercial dishwashers during a wash rinse or sanitization cycle. A cold water spray is used to create a pressure reduction zone which serves to draw in hot, highly humid air from the dishwasher. Water vapor cools and condenses on contact with the cold water spray within the venturi. The invention also serves to help vent the dishwasher. Cool, fresh air is drawn into the dishwasher while the hot air is drawn into the venturi.
