Patent number: 11137207Abstract: A method and apparatus for the continuous sublimation of a substance includes cascading a material containing a substance capable of sublimation, such as water, between a plurality of trays vertically stacked within a processing zone provided within a processing chamber. A substantially atmospheric environment is maintained within the processing zone at a temperature whereby the substance sublimes forming a sublimate within the environment. The environment containing the sublimate is contacted with a drying agent such as a desiccant to maintain the environment whereby the substance sublimes at substantially atmospheric pressure and at the controlled temperature.Type: GrantFiled: January 16, 2020Date of Patent: October 5, 2021Assignee: Wyssmont Company Inc.Inventor: Edward Weisselberg

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

Patent number: 8840782Abstract: Biosolids in the nature of sewage sludge are processed in a controlled environment to produce a dried sludge product of relatively high dry solid content with the elimination of or reduced levels of pathogens. The water containing sewage sludge is dried while cascading within a processing chamber using heated air at a temperature below the ignition or smoldering temperature of the sewage sludge to prevent the formation of embers. The sewage sludge before discharge is retained within the processing chamber for a sufficient time and temperature as mandated by the Environment Protection Agency rules and guidelines.Type: GrantFiled: October 23, 2013Date of Patent: September 23, 2014Assignee: Wyssmont Company Inc.Inventor: Edward Weisselberg

Patent number: 8784649Abstract: A method for the pyrolytic extraction of hydrocarbons such as shale oil from kerogen. Oil shale containing kerogen which has been ground into particulate form, is cascaded downwardly between a plurality of rotating trays within a heated processing chamber. As the hydrocarbons are volatized within the chamber, the volatiles are collected and condensed within a condenser or other suitable recovery apparatus.Type: GrantFiled: November 15, 2012Date of Patent: July 22, 2014Assignee: Wyssmont Company Inc.Inventor: Edward Weisselberg

Publication number: 20140048387Abstract: A method and apparatus for processing material cascading through a treatment chamber uses a plurality of vertically stacked shelves divided into trays by spaced apart openings. As the shelves rotate, material contained with each tray is discharged through one of the openings to one or more trays of an underlying shelf. The material to be processed is supplied to the uppermost shelf through one or more material inlets, and discharged from the lowermost shelf through one or more material outlets. The material that enters each feed opening stays substantially together as it spirals down through the chamber. The multiple trays provide for shorter retention time of material within each tray which is adaptable for processing heat sensitive materials along separate material flow paths within the treatment chamber.Type: ApplicationFiled: October 23, 2013Publication date: February 20, 2014Applicant: WYSSMONT COMPANY INC.Inventor: Edward Weisselberg
