Abstract
A method and/or apparatus for drying material by disposing the material against a heated surface that has a charged electrode arrangement disposed adjacent the surface and cooperating therewith to define a plurality of alternately arranged non-uniform electrostatic fields extending between the electrode arrangement and the surface with each non-uniform field having the higher intensity portion thereof substantially oppositely located relative to the higher intensity portion of an adjacent non-uniform field so that the fields can at least partially extend through the material when the material is disposed against the surface and between the surface and the electrode arrangement.
Claims27
In a method for drying material by disposing said material against a heated surface means, the improvement comprising the steps of disposing charged electrode means adjacent said surface means to cooperate therewith to define a plurality of alternately arranged non-uniform electrostatic fields extending between said electrode means and said surface means with each non-uniform field having the higher intensity portion thereof substantially oppositely located relative to the higher intensity portion of an adjacent non-uniform field so that said fields at least partially extend through said material while said material is disposed against said surface means and between said surface means and said electrode means, and causing relative movement between said electrode means and said material so that said non-uniform electrostatic fields serially act on at least a portion of said material while said portion of said material is being heated by said heated surface means.
In a method for drying material by disposing said material against a heated surface means of a dryer drum-like member to have said heated surface means heat at least part of the liquid particles of said material, the improvement comprising the steps of disposing charged electrode means adjacent said surface means to define a plurality of spaced apart substantially constant and non-current consuming electrostatic fields extending between said electrode means and said surface means so that said fields at least partially extend through said material while said material is disposed against said surface means and between said surface means and said electrode means, and moving said material in one direction to cause at least a portion of said material to have the particles of liquid thereof serially moved through an electrostatic field into a non field area and then into the next electrostatic field in a repetitive manner whereby said particles of liquid of said portion of said material are subjected to a pumping action by said spaced apart substantially constant and non-current consuming electrostatic fields while said portion of said material is being heated by said heated surface means.
In a method for drying material by disposing said material against a heated surface means to have said heated surface means heat at least part of the liquid particles of said material, the improvement comprising the steps of disposing charged electrode means adjacent said surface means to define a plurality of alternately directed and oppositely charged electrostatic fields that are substantially constant and non-current consuming and that extend between said electrode means and said surface means so that said fields at least partially extend through said material while said material is disposed against said surface means and between said surface means and said electrode means, and moving said material in one direction to cause at least a portion of said material to have the particles of liquid thereof serially moved through an electrostatic field with its negative charge adjacent said electrode means and then into the next electrostatic field with its positive charge adjacent said electrode means in a repetitive manner whereby said particles of liquid of said portion of said material are subjected to an alternately directed pumping action by said electrostatic fields while said portion of said material is being heated by said heated surface means.
