  • Patent number: 7694432
    Abstract: The present invention concerns a method and apparatus for dehumidifying, drying or the like of different materials. The invention is developed primarily for dehumidification of sewage sludge (7), but it may be utilized for many different materials including foodstuffs as crispbread and pasta. The sludge (7) or other material is dehumidified or dried in a chamber (1) by means of thermal radiation. The thermal radiation is given by means of one or more elements (2) for thermal radiation. The thermal radiation is concentrated to one or more distinct wavelength ranges at which water has peaks for absorption of radiation energy. Air is circulated in the chamber (1), to take up moisture evaporated from the material.

  • Patent number: 7441345
    Abstract: A laundering aid having a core member, such as an elastomeric ball member, that includes a covering comprising an abrasive or brush-like material adapted for engaging and lifting matter, such animal hair, adherent to the surface of fabric articles when the laundering aid is placed into contact with clothing and other fabric articles within an operating tumble-type clothes dryer. The covering may further include a second material comprising a material that substantially lacks characteristics for lifting matter from other fabric, the first material being disposed adjacent to or over the first material to form a series of discrete sections having different properties that facilitate the dislodgement and or removal of the hair or other fine matter. The exemplary elastomeric ball member may be inflated for shape retention, while allowing for expansion when heated during the drying cycle.

  • Patent number: 7383643
    Abstract: An apparatus and method is provided to dry veneer or other items by vaporization of moisture in the item. Apparatus has an insulated chamber with a frame and a drawer with a door. A mesh surface of the drawer supports item for drying with a heater at sub-atmospheric pressure inside of the chamber. Item is placed on the layer of mesh of the drawer of the apparatus and secured with fasteners such as another layer of mesh. The drawer with fastened item is placed into the chamber of the apparatus. With the drawer fully engaged within the chamber, the drying apparatus is closed with an airtight seal. A pump draws a vacuum in the chamber and heat is directed at the item to raise the temperature of the item to less than 160° F., particularly between 120° F. to 150° F. Apparatus can dry veneer in less than five minutes.

  • Patent number: 7367139
    Abstract: This vacuum processing apparatus has a fixed processing chamber 24 and two movable load lock chambers 28a and 28b. A gate valve 26 is provided on the processing chamber 24, and gate valves 30 are respectively provided on the load lock chambers 28a and 28b. Each of the load lock chambers 28a and 28b is moved in a Y direction by a preparatory chamber moving mechanism 34. A vacuum seal 54, which is expandable and shrinkable so as to vacuum seal a gap G between the gate valves 26 and 30 which are set close to each other during the expansion, is provided around a peripheral edge portion of the processing chamber gate valve 26. Further, a substrate transporting mechanism for transporting a substrate 2 between the processing chamber 24 and each of the load lock chambers 28a and 28b set close thereto.

  • Patent number: 7347006
    Abstract: A processing apparatus includes a first detection unit for detecting a temperature of an inner wall of the vacuum vessel, a second detection unit for detecting a temperature of the processing unit, and a first control unit for controlling a temperature of the gas. The first control unit controls the temperature of the gas based on a temperature gradient between the temperatures of the inner wall and the gas or a temperature gradient between the temperatures of the processing unit and the gas. A method for removing particles from a processing apparatus includes a first detection step for detecting a temperature of an inner wall of the vacuum vessel, a second detection step for detecting a temperature of the processing unit, a first control step for controlling a temperature of the gas, and a gas introduction step for introducing the gas into the inner space of the vacuum vessel.
