Rotary Dryers

McGill AirPressure designs and manufactures vacuum rotary dryers for drying difficult or sticky materials that can withstand agitation. Drying takes place in a cylindrical chamber with an internal agitator. Vacuum dryers remove moisture by exposing the materials to reduced pressure. Just enough heat is used to replace that lost through vaporization.

   The jacketed shell is horizontal and cylindrical in shape. A double-flight of spiral ribbon or heavy-duty paddles is attached to a rotating shaft inside the dryer. During operation, the ribbons or paddles move material from the center of the dryer to the end plates and back so that the batch is constantly exposed to the heated shell and shaft. This action also allows for ready discharge.

  The shell and shaft are heated by steam, water, oil, or another high-temperature fluid. Standard working volumes range from 2 to 300 cubic feet. Rotary dryers are fabricated from carbon steel, stainless steel, or special alloys.
