| Number | Title | Issue Date |
| 8161663 | System and method for drying and torrefaction A method and apparatus 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... | 04/24/2012 |
| 7309379 | Moving bed adsorber/desorber and low flow (high yield) desorber devices and their methods of use Moving bed adsorber and desorber apparatus and methods, wherein adsorbent material (e.g., beads of resin) moves over a series of vane members and a fluid flow passes between the vane members and through the flowing bed of adsorbent. An adsorbent depth regulator is p... | 12/18/2007 |
| 6754979 | Device for drying and thermally treating granulates with an inert gas stream An apparatus (1) is proposed for drying and heat-treating pellets with a stream of inert gas, wherein the apparatus has a cuboid base unit (2) with a feed (3) for the pellets in its upper part and an outlet (4) in its lower part, with a f... | 06/29/2004 |
| 6745493 | System and method for drying toner particles A method of drying wet toner particles includes adding different sized wet toner particles to a dryer drying chamber and drying each of the wet toner particles for a drying time TD. The drying time TD can vary for each toner particle and is pro... | 06/08/2004 |
| 6601315 | Combined fluidized bed dryer and absorption bed A combined fluidized bed dryer and absorption bed allows an absorbant to be dried to remove any moisture therefrom immediately followed by treating a product material with the dried absorbant, all in the same vessel, such that the absorbant is at its opti... | 08/05/2003 |
| 6516537 | Method for drying and producing microporous particles In a process for drying microporous, fluid-containing particles, the fluid-containing particles to be dried are fed as a moving bed countercurrently to a drying fluid, the interfacial tension of the fluid being reduced in comparison with the interfacial t... | 02/11/2003 |
| 5819430 | Bead dewatering apparatus and method Apparatus and a method for de-watering a bead suspension of fragile beads having a high water content suspended in a liquid includes a staging vat, a metering vat, and a de-watering vat. The application of pressurized gas to the staging vat causes the bea... | 10/13/1998 |
| 5412882 | Method and heat-exchanger for preheating broken glass and glass-batching melt-goods or similar bulk goods using a heating gas As a rule a melt-good consisting of glass fragments and glass batching will be moist and tend to agglomerate and bridge-form when being preheated in a plate heat-exchanger 10 whereby the travel of the melt-good through the plate heat-exchanger 10 may be b... | 05/09/1995 |
| 5177876 | Reactor installation for countercurrent treatment of gases and bulk solids The invention relates in general to a reactor installation for countercurrent treatment of gases and bulk solids and, in particular, to a moving bed reactor installation with at least one reaction chamber which latter has at least one inlet and at least o... | 01/12/1993 |
| 4506453 | Enhanced heat transfer process by forced gas recirculation An enhanced heat transfer process whereby solid particles are heated, dried, or cooled by a gas: Particles are repeatedly lifted and dropped as, for example, in flighted rotary drums. By forced recirculation, gas is passed through showering particles gene... | 03/26/1985 |
| 4371375 | Apparatus and process for drying sawdust A sawdust drying apparatus and process wherein sawdust passes downwardly in a sinuous fashion to and through multiple, vertically spaced dryer plates at a temperature and velocity so as to progressively dry the sawdust and render it suitable as a highly c... | 02/01/1983 |
| 4351119 | Apparatus and method for drying compact, vitrifiable mixtures In apparatus and method for treating granular product within a cylindrical chamber as the product, by the force of gravity, falls through a plurality of regions maintained at varying temperature and pressure. Structure formed by at least a pair of collect... | 09/28/1982 |
| 4165216 | Continuous drying and/or heating apparatus This invention comprises an apparatus and process for drying and/or heating materials. This invention was designed for use in the production of charcoal from wood feed material; however, it can be used to heat and/or dry many types of materials. Feed mate... | 08/21/1979 |
