Abstract
Method and apparatus for use in drying biomass particles provide a dryer having a chamber for a predetermined volume of biomass particles with apertures distributed throughout one boundary of the chamber enabling hot gas to be introduced and forced through the particles to exit from the opposite boundary. The gas stream to the chamber is so regulated that a layer of particles adjacent the opposite boundary functions as a relatively cool filter bed operable to prevent, to a desired extent, noxious liquids, gaseous, or particulate emissions from exiting from the dryer.
