Xerox Disclosure Journal
A system for surface treatment conditioning of bulk powder materials is disclosed. The system comprises a humidifieddehumidifier for generating and regulating the proper moisture content in a conditioning gas and a dispersion wand through which the gas is pumped and dispersed through the bulk powder contained in a vessel by percolation. The gas is allowed to escape from the vessel while any aerosolized particulate material is retained within the vessel by an appropriately chosen filter means. Several advantages of this system are: rapid and uniform conditioning of bulk powders; easy portability and set-up; adaptable to different process scales; particulate emissions and exhaust pollution are easily controlled; and suitable for use with many different materials, for example, polymer resin beads, toner powders, surface additives, and the like.
