  • Air-assisted wiping device
    Patent number: 6023855
    Abstract: The invention provides an air-assisted wiping device for use in a continuous-spray dryer. The air-assisted wiping device rotates inside the housing to continuously wipe heavy sticky powder from the walls of the housing using a wiper blade. The air-assisted wiping device includes an elongated hollow plenum having a flow-directing slot disposed along its length. Air received into the elongated hollow plenum is passed through the flow-directing slot onto a wiper blade, which is coupled to the elongated hollow plenum. The air discharged onto the wiper blade removes powder that collects on the leading side of the wiper blade.
