ABSTRACT:
An apparatus including: a conduit operably connected to a source and extending downwardly therefrom, the conduit being adapted to permit a flow of particulate material from the source through the conduit; a fluidizing nozzle operably connected to the conduit and extending downwardly therefrom, the nozzle defining an inlet for receiving material from the conduit and defining an outlet for dispensing material from the nozzle to a receiver, the inlet defining an inlet cross sectional area perpendicular to the flow the material and outlet defining an outlet cross sectional area perpendicular to the flow the material, the inlet cross sectional area being larger than the outlet cross sectional area; the nozzle being adapted with a plenum including an inlet port for receiving compressed gas and a chamber adapted to communicate the gas to the porous walls of the nozzle, and an outlet port for engaging a vacuum source to continuously evacuate the receiver while the nozzle is engaged with the receiver; a conveyor located at least partially within the conduit, the conveyor assisting to provide the flow of material from the source to the receiver, and an electromagnetic valve located adjacent to at least a portion of the conduit, the electromagnetic valve being adapted to supply a magnetic force to the material in the conduit until a second receiver replaces the first receiver, the magnetic force being sufficient to restrict or stop the material flow through the nozzle.
