  • Patent number: 4378640
    Abstract: A fluid flow deflector apparatus is described including a helical shaped deflector member. The deflector member is positioned in the path of a fluid stream, such as hot air, to deflect the flow of such stream thereby producing turbulence to mix the fluid and prevent laminar flow. The deflector member can be positioned with its axis extending substantially parallel to the direction of flow of the fluid stream. Thus, in one embodiment the deflector member is positioned inside a conduit to provide a heat exchanger apparatus in which hot air or other heating fluid is deflected into contact with the inner surface of the conduit in order to heat another fluid in contact with the outer surface of such conduit.

  • Patent number: 4127946
    Abstract: A method and apparatus are disclosed for drying materials by contact with a drying gas consisting essentially of internally generated superheated drying steam above 212.degree. F., to vaporize the water in the material and remove it to produce the steam used for drying. A minor portion of steam is removed from the drying gas and discarded to maintain pressure equilibrium. The drying steam is produced within the drying chamber from water evaporated from the material being dried and is either heated within the drying zone where it is in contact with the material or removed from the drying zone, heated to form superheated steam, and returned to the drying zone for contact with the material during drying. A wood veneer dryer employing the invention is described as well as an apparatus for drying particulate material.

  • Patent number: 4121350
    Abstract: A dryer apparatus is disclosed for drying sheet materials by contact with a drying fluid which is deflected towards the opposite surfaces of the sheet by deflector members spaced longitudinally along such sheet. A major portion of the drying fluid consists of internally generated superheated drying steam above 212.degree. F, to vaporize the water in the sheet material and remove it to produce the steam used for drying. A minor portion of steam is removed from the drying fluid and discarded to maintain pressure equilibrium. The drying steam is produced within the drying chamber from water evaporating from the material being dryed and is either heated to form the superheated steam within the drying zone where it is in contact with the sheet material or is removed from the drying zone, heated to form superheated steam and returned to the drying zone for contact with the sheet material during drying.
