Patent number: 11684948Abstract: A spray coating machine and process accommodates coating pans of various sizes and simplifies cleaning after particulate material in the pan is coated. A selected pan is supported on a trolley carried by a wheeled cart. After the cart is positioned adjacent the coating machine, the trolley and pan are extended into the machine, and then the pan lifted for support by a rotatable drive shaft and castors. The trolley is then removed from the machine, and the door is closed so that the coating process can commence. When coating is complete, the door is opened, and the trolley extended into the machine under the pan and raised for removal of the castors. Then, the trolley and pan are withdrawn from the machine. The trolley does not need cleaning after spraying, since the trolley is outside the machine during spraying of the coating solution.Type: GrantFiled: November 25, 2020Date of Patent: June 27, 2023Assignee: Freund-Vector CorporationInventor: Nicholas Decker

Patent number: 8807070Abstract: The improved rotor processor of the present invention includes a stator with a rotatable rotor defining a rotor chamber in which particles are circulated for coating or layering. A spray gun mounted to the stator adjacent the rotor directs liquid into the rotor chamber, while a powder feed system mounted in the stator adjacent the rotor directs dry powder into the rotor chamber. The spray gun and powder feed system are spaced apart circumferentially so as to define a spray zone and a separate powder zone through which the circulating particles repeatedly and sequentially pass. The powder feed system includes a feed screw conveyor, an eductor, and a flexible conduit for delivering micronized powders, such as polymers or glidants, to the rotor chamber.Type: GrantFiled: July 27, 2009Date of Patent: August 19, 2014Assignee: Vector CorporationInventor: Brian K.

Patent number: 7753298Abstract: A rotor processor includes a stator chamber and a rotor mounted for rotation within the chamber. The rotor has a perimeter edge spaced closely to the interior wall of the chamber so as to define a slit or gap there between. The rotor is slidably mounted upon a rotor shaft, for movement between raised and lowered positions during operation of the processor, so as to automatically adjust the dimension of the slit, without operator intervention. As air flows from a plenum beneath the rotor, through the slit, and into the chamber, a pressure differential is created, which provides a lifting force to raise the rotor. The pressure drop is maintained relatively constant at a predetermined level after a lifting equilibrium force is achieved, regardless of the air flow volume.Type: GrantFiled: January 31, 2007Date of Patent: July 13, 2010Assignee: Vector CorporationInventor: Aaron K. Basten

Patent number: 7363830Abstract: A discrete volume vacuum sampling device is provided with a vacuum tube, a sample tube, and a sample container. The container defines a discrete volume of product to be sampled from a product bed within a processing machine. The sampler tube extends between the container and the machine containing the product to be sampled. When a vacuum is applied through the vacuum tube, a door on the container is pulled shut, thereby increasing air velocity in the sampler tube, so as to draw product from the bed upwardly through the sampler tube and into the container. When the container is full, the vacuum is stopped, such that the weight of the product in the container pushes the door open for discharge of the discrete volume of product sample, while product remaining within the sampler tube is discharged back into the bed of material within the machine.Type: GrantFiled: April 26, 2006Date of Patent: April 29, 2008Assignee: Vector CorporationInventor: Lee J.
