Patent number: 7654222Abstract: A fluidized bed apparatus includes a fluidizing container, a porous plate, a lower spray nozzle, a bag filter, an upper spray nozzle, a backwash nozzle, and a backwash nozzle elevator. The fluidizing container is formed in an inverted truncated conical cylindrical shape. The porous plate is provided so as to block a lower opening of the fluidizing container. The lower spray nozzle jets out air into the fluidizing container via the porous plate. The bag filter is provided at an upper opening of the fluidizing container. The upper spray nozzle sprays spray liquid downward. The backwash nozzle sweeps away powder particulates adhered to the bag filter by jetting out air from the outside of the bag filter toward the inside and is moved up and down by the backwash nozzle elevator. The fluidizing container may be vibrated by a vibrator.Type: GrantFiled: December 13, 2006Date of Patent: February 2, 2010Assignee: Fuji Paudal Company LimitedInventors: Yoshifumi Osako, Naochika Asai, Takashi Ueno

Patent number: 7637999Abstract: A fluidized bed reactor for granulating and coating particles in very small amounts having an essentially conical product container, a filter housing with filters inserted above the product container, and a lower housing below the conical product container having a process air supply. The product container has a sieve bottom in the center of which is a height-adjustable two-component nozzle. At least one guide element associated with the sieve bottom directs at least part of the process air to the two-component nozzle in a radial manner.Type: GrantFiled: November 16, 2005Date of Patent: December 29, 2009Assignee: Glatt Process Technology GmbHInventors: Manfred Struschka, Winfried Thomann, Jochen Dressler

Publication number: 20090196991Abstract: A new device and process for continuously applying coatings, such as resin and additives or polymers or the like, to minerals is disclosed. The device and apparatus differ substantially from standard batch coating processes currently used by industry. The apparatus uses a horizontal cylinder with an internal auger and a series of injection ports distributed along the cylinder. Minerals that are to be coated are pretreated and passed through the mixing cylinder using the auger (which may comprise one or more screws with variable pitch blades). As the mineral particles pass through the cylinder various coating materials are injected by the injection ports. The complete system is described, the method of use is explained and the control system which allows for different products is described.Type: ApplicationFiled: August 15, 2005Publication date: August 6, 2009Inventors: Robert H. Mizwicki, Kelley J. Kerns

Patent number: 7563325Abstract: An improved Wurster coater in which conditioned fluidizing gas, drawn through a coating chamber bowl from a plenum by a vacuum fan, is directed through a perforated gas distribution plate through one or more Wurster tubes. The perforated gas distribution plate defines three concentric gas flow zones: a central high-flow up-bed zone beneath the Wurster tube, a surrounding annular lower-flow down-bed zone, and an outer peripheral bypass zone defining a bypass cavity underlying the outer lower wall of the bowl. A controlled bypass flow of conditioned fluidizing gas is directed into the bypass zone, either around the edge of the distribution plate or through relatively larger holes in its plate's outer periphery, which causes that portion of the fluidizing gas to flow radially inward across the distribution plate, thereby sweeping particles away which would otherwise stagnate at the inner corners of the bowl due to low gas velocity in that region.Type: GrantFiled: June 30, 2006Date of Patent: July 21, 2009Inventors: Martin P. Bender, Joseph P. Szczap, Donald P. Verbarg

Publication number: 20090145355Abstract: An apparatus for treating a plurality of particles, such as ammonium sulfate, with a coating, such as a wax, to prevent caking of the particles. The apparatus includes a feed chute, a diffuser and an exit chute. An applicator is mounted adjacent a base of the diffuser for spraying the coating downwardly away from the diffuser into a predefined pattern. The exit chute includes a deflector for intersecting a curtain of particles falling from the diffuser and for redirecting the particles into the predefined pattern of the coating. A heating element is mounted to the deflector for maintaining a predetermined temperature of the deflector thereby preventing accumulation of the coating on the deflector.Type: ApplicationFiled: September 10, 2008Publication date: June 11, 2009Inventors: Jay R. Garner, Paul R. Meiller, Dominick A. Burlone, R. Merritt Sink, Judy Easterling

Patent number: 7544250Abstract: An apparatus for treating a particulate material, in particular for mixing, drying, granulating, pelletizing and/or coating the material, has a container which has a process chamber arranged around a longitudinal mid-axis of the container and formed as an annular chamber, and also a container central duct, separated from the process chamber, as a flow duct for process air, which duct opens into the lower region of the process chamber, an upper region of the process chamber being open. In at least one first operating state, the upper open region of the process chamber communicates with the container central duct so as to conduct process air, by the container central duct widening circumferentially towards the upper region of the process chamber and opening towards the process chamber.Type: GrantFiled: April 2, 2004Date of Patent: June 9, 2009Inventor: Herbert Hüttlin
