Abstract
A system utilizing a rotary atomizer for applying a liquid based substance to particles. In one example, a motor provides an in-line, direct drive force on a cage atomizer. With some systems, the cage atomizer has a vertical axis of rotation. With some systems, the motor is mounted external to the particle path and supported by a housing structure that provides an angled particle path. With some systems, other types of rotary atomizers may be used such as disk, bowl, or hollow disk rotary atomizers. With some examples of cage atomizers, a first portion of the cage atomizer may include a thread set that screws to a thread set of a second portion to hold a perforated structure in place. With some systems, the thread sets surround the axis of rotation.
Claims25
An apparatus for applying a liquid based substance to particles comprising:
- a particle path housing defining a particle path;
- a cage atomizer located to provide a zone of atomized liquid within the particle path, the cage atomizer having a generally vertical axis of rotation;
- and
- a motor having a shaft coupled to the cage atomizer for rotation of the cage atomizer,
- said cage atomizer including;
- a first support structure;
- a second support structure;
- a perforated structure located between the first and second support structures, the rotation of the atomizer providing a centrifugal force on a liquid based substance through the perforated structure;
- a first set of threads surrounding the axis of rotation and fixably coupled to the first support structure;
- and
- a second set of threads surrounding the axis of rotation and fixably coupled to the second support structure,
- wherein said first and second support structures are coupled at least via an engagement of the first and second set of threads.
An apparatus for applying a liquid based substance to particles comprising:
- a particle path housing defining a particle path;
- a cage atomizer located to provide a zone of atomized liquid within the particle path, the cage atomizer having a generally vertical axis of rotation;
- and
- a motor having a shaft coupled to the cage atomizer for rotation of the cage atomizer,
- said cage atomizer including first and second spaced apart structures, an elongated central shaft assembly defining the axis of rotation of the cage atomizer extending between and interconnecting the structures, and a perforated structure surrounding the shaft assembly between the first and second structures, said shaft assembly having threading surrounding said axis of rotation permitting disassembly of the atomizer.
