Patent number: 6911087Abstract: A fluidized bed apparatus for applying a coating liquid onto the surface of particles includes a vertically disposed cylindrical product container having a peripheral wall, at least one cylindrical partition defining a centrally located up bed region and a peripherally located down bed region. The product container further includes an upper end connected to an expansion chamber and a lower end including an orifice plate having a plurality of openings for passage of fluidized air or gas. A nozzle is centrally located through the orifice plate and is adapted to generate a spray of coating liquid upwardly into the up bed. Particles located within the product container circulate upwardly through the partition and the coating liquid spray, between the up bed and the down bed. A central discharge assembly is provided at the lower end of the product containers for emptying particles from the machine.Type: GrantFiled: May 1, 2003Date of Patent: June 28, 2005Assignee: Glatt Air Techniques, Inc.Inventors: David M. Jones, Richard Andrew Smith, John Patrick Kennedy, Frank Maurer, Matthias Georg Tondar, Bernhard Luy, Markus J. Baettig

Patent number: 6695919Abstract: A fluidized bed apparatus for applying a coating liquid onto the surface of particles includes a vertically disposed cylindrical product container having a peripheral wall, at least one cylindrical partition defining a centrally located up bed region and a peripherally located down bed region. A nozzle is centrally located through the orifice plate and is adapted to generate a spray of coating liquid upwardly into the up bed. A nozzle ramp is provided around the nozzle. The nozzle ramp is generally cusp shaped and includes nozzle-ramp surface. The nozzle ramp is centrally positioned around the nozzle and is directed upwardly towards the partition so that the nozzle-ramp surface directs particles moving generally horizontally across the orifice plate from the down bed upwardly into the partition and the up bed. The nozzle ramp may further include air passages for passing fluidized air upwardly to the nozzle-ramp surface.Type: GrantFiled: May 1, 2003Date of Patent: February 24, 2004Assignee: Glatt Air Techniques Inc.Inventors: David M. Jones, Richard Andrew Smith, John Patrick Kennedy, Frank Maurer, Matthias Georg Tondar, Bernhard Luy, Markus J. Baettig

Patent number: 5437889Abstract: A shield, such as an upstanding cylindrical partition, is mounted adjacent to an air source, such as an air distribution plate/screen of a Wurster system processor, whereby the open upper end of the partition is generally horizontally registered with and disposed about the upper extremity of an associated spray nozzle. The open lower end of the inner cylindrical partition is generally sealed relative to the air distribution plate/screen and operative to receive air upwardly therethrough for subsequent passing through the inner partition about the spray nozzle. The upper end of the inner tubular partition shields the initial spray pattern discharged from the spray nozzle and prevents the premature entrance of particles moving into the spray nozzle area.Type: GrantFiled: August 9, 1993Date of Patent: August 1, 1995Assignee: Glatt Air Techniques, Inc.Inventor: David M.

Patent number: 5251384Abstract: A fluidized bed apparatus having a downwardly opening filter housing and including multiple processing gas outlets and a partition structure dividing the interior of the filter housing into individual downwardly-opening open-bottom compartments equal in number to the gas outlets. The partition structure extends into an expansion chamber below the filter housing. The partition structure that divides the housing not only extends the full height of the filter housing portion, but projects appreciably downwardly therefrom into the upper portion of the expansion chamber disposed below the filter housing. Each gas outlet is associated with a filter cartridge mounted on a tubular fitting. The gas filter cartridge is tubular and filters the gas passing through each of the divided filter housing compartments.Type: GrantFiled: June 28, 1991Date of Patent: October 12, 1993Assignee: Glatt Air Techniques, Inc.Inventors: Kenneth W.
