Abstract: An air modulating non-thermal dryer (AMND) system that de-waters a wet feedstock stream with an ambient airstream, to produce a dried product stream. The system utilizes a drying chamber in the efficient production of a dried product, and includes an acoustic induced air motion liberation or “SONICATION™” of the moisture with a combination of drivers, labyrinth transmission lines, and air modulating devices. Initially, a 50% to 60% dry composite of biomass or biosolids is pneumatically conveyed to the chamber through an in-line cutter and a swiveling load leveler with an atomizing nozzle for final shredding. The system can liberate up to 90% of the moisture content, using high volumes of process air, along with infeed motive air to deliver wet feedstock material into the chamber. Expelled airborne moisture may be discharged to atmosphere, without further processing, or it may be recaptured for potable uses.

Abstract: An apparatus and method for drying and deagglomerating substances of finely-divided solids suspended in a fluid medium. The apparatus includes the basic components of a phenumatic friction dryer, a flash dryer and a ring dryer.
