Latest Patents
Ferrell's latest patent is for a rotary biomass dryer. This innovative system features a helically threaded auger shaft that is rotatably driven by a prime mover, such as an electric motor. Notably, the dryer does not require an external heat source to dry wet biomass material. Instead, the design incorporates variable width helical threads on the shaft, increasing the compression applied as the biomass material moves through a generally cylindrical bore. A variable compression nozzle at the distal end of the bore can be adjusted to achieve desired moisture content levels in the dried biomass material. This nozzle is designed for automatic control, featuring segments that are forced radially inward to enhance the compression force applied to the biomass, showcasing the advanced engineering involved in Ferrell's design.
