Patent ID: 7273075

Claim:
A powder-fluidizing apparatus for feeding bulk powder into an external applicator, comprising: a base comprising an inlet port and outlet port; and a pressure housing attached to the base, wherein the pressure housing internally comprises, a hopper assembly, comprising, a motor with gearhead assembly which is located at a top of the hopper assembly, a sieve plate with holes in it attached to an outlet on a bottom of the hopper assembly, a drive shaft, extending through the bulk powder, wherein a top of the drive shaft is attached to the motor with gearhead assembly, and a brush, which makes contact with the sieve plate, and which is attached to a bottom of the drive shaft, wherein the motor with gearhead assembly rotates the drive shaft and brush at a prescribed speed across the sieve plate, and the action of the brush rotating across the sieve plate sweeps the powder over and through the holes in the sieve plate, serving to break up agglomerated particles in the powder as they are swept through the holes, resulting in the powder dropping out of the holes from a bottom side of the sieve plate.
