Device for dispensing particulate matter and system using the same

Abstract

A particulate dispensing device includes a housing having a wall at least partially forming a housing cavity. A dispersive element and a particulate filter are each supported in the housing cavity in spaced relation to one another forming a fluidizing chamber. A dispensing tube extends from the fluidizing chamber for dispensing fluidized particulates or aerosol from the device. The particulate dispensing device generates the fluidized particulates or aerosol from a particulate bed within the fluidizing chamber, and dispense the particulates through the dispensing tube to a downstream delivery site. One or more dispensing devices can be used in a system to deliver the fluidized particulate matter to the delivery site. In one system a delivery line from an associated dispensing device directly delivers particulate matter to the delivery site. In another system, each delivery line of one or more dispensing devices delivers particulate matter to an associated delivery member that includes a longitudinally extending channel having an exit orifice. A propellant source is in fluid communication with a propellant port in the channel, and provides propellant flow along the channel. The dispensing lines deliver the fluidized particulate matter or aerosol into the propellant flow. The delivery site is supported adjacent the exit orifice such that the propellant flow and particulate matter therein are delivered to the delivery site.
