Abstract
This invention provides a mixing chamber that utilizes several tined cylinders to convey materials through the mixing chamber for applying liquid additives to the materials. Each of the tined cylinders includes a number of spring biased tines extending from the surface of the cylinder. The tined cylinders are arranged within the mixing chamber such that, as the tined cylinders rotate about an axis, the spring biased tines engage the materials within the mixing chamber and 'sweep' them along towards a discharge opening of the mixing chamber. As the materials are conveyed through the mixing chamber, an additive liquid, typically containing various chemicals, colorants, dies, and/or paints, is sprayed onto the materials. In this manner, liquid additives are applied to materials more evenly and more thoroughly, resulting in a more consistent finished product.
