McGill AirPressure designs and manufactures vacuum conical dryers for drying free-flowing materials that cannot stand attrition. Drying takes place in a conical chamber that rotates end over end to create a gentle folding and mixing action. Vacuum dryers remove moisture by exposing the materials to reduced pressure. Just enough heat is used to replace that lost through vaporization.

   Standard working volumes range from 1 to 348 cubic feet. Their custom sizes are available on request. Vapor-contacting parts are fabricated from carbon steel, stainless steel, or special alloys.
