Abstract
An apparatus for cooling material, such as a PVC compound, includes a chamber having an inner surface and an inner space configured for receiving material to be cooled. A rotatable shaft extends through the chamber inner space, and is operable for being rotated by a motor. At least one mixing tool is coupled to the shaft to rotate with the shaft, and mix the material while rotating around the inner surface of the chamber so the material contacts the inner surface to be cooled thereby. In one embodiment, the mixing tool includes a flexible blade configured for contacting the chamber inner surface and for sweeping across a portion of the inner surface to dislodge an amount of material from the surface portion. Another embodiment utilizes an air knife to dislodge material from the inner chamber surface. The motor is operable for rotating the shaft at a speed in the range of 150 to 250 rpm to sweep the material from the inner surface.
