Abstract: An infrared heating system is disclosed that includes an enclosed tube extending from a first open end to a second open end, the enclosed tube having a sidewall opening in a sidewall of the tube at a location between the first and second open ends; an infrared heater mounted to the exterior of the enclosed tube such that heating elements of the infrared heater are exposed to the tube sidewall opening; and an auger disposed within the enclosed tube, the auger being driven by a drive system such that material fed into the enclosed tube at the first open end is transported to the second open end of the tube and is exposed to the heating elements of the infrared heater as the material is transported between the first and second open ends.

Abstract: A rotatable drum for an infrared drying system includes a body having a first end defining an entry opening, an opposite second end, and a plurality of planar sides extending therebetween. At least one of the planar sides defines an exit opening adjacent to the first end. An interior cavity is defined by the first and second ends and the planar sides, and the interior cavity is configured to receive solids at the entry opening and discharge solids at the exit opening. The body also includes at least one flight extending from an interior surface of the body into the interior cavity. The at least one flight is configured to channel solids from the entry opening to the back end when the drum is rotating clockwise and to channel solids from the second end to the exit opening when the drum is rotating counter-clockwise.

Abstract: A process for drying wet organic solids to below 10 percent by weight is disclosed wherein an infrared drying system having a housing, a conveyor extending through the housing, at least one infrared heater located within the housing, and a fan for moving an airflow stream through the at least one infrared heater and onto the conveyor. Another step in the process can be providing and feeding wet organic solids onto the conveyor at a metering rate. In one embodiment, the wet organic solids have a moisture content of about 80 percent by weight. Moisture is removed from the wet organic solids by exposing the wet organic solids to at least one infrared heating element within the drying system and an airflow stream that has been heated by the at least one infrared heating element.
