Patent number: 9273263Abstract: A method for torrefaction of water containing cellulosic materials is performed in an inert atmosphere. The cellulosic material is cascaded through the apparatus between a plurality of rotatable trays vertically stacked within multiple processing zones. Steam being generated from heating of the cellulosic material is recycled back to the apparatus to provide an inert atmosphere. The steam may be superheated in a heat exchanger. Exhaust from the torrefaction zone of the apparatus has some moisture and other volatiles removed prior to being reheated in a burner. The heated exhaust is used in the heat exchanger to superheat the recycled steam.Type: GrantFiled: July 29, 2013Date of Patent: March 1, 2016Assignee: Wyssmont Company Inc.Inventors: Edward Weisselberg, Joseph Bevacqua, Robert Borre
