Abstract
Powder fluidizing apparatus includes a unitary pressure vessel having a powder compartment and a transfer compartment, a lid on a first open end of the powder compartment and a base on a second end of the unitary pressure vessel, the second end sealing an open end of the transfer compartment. A plate separates the powder compartment from the transfer compartment, the plate being located between the lid and the base. A coupling collar secures a sieve disk packet in an opening in the plate. A tube extends from the transfer compartment to the powder compartment, the tube extending to a location near the lid of the unitary pressure vessel. When the transfer compartment is pressurized with a carrier gas, pressure in the transfer compartment and pressure in the powder compartment are equalized by the tube. The unitary pressure vessel is configured to contain the carrier gas in both the powder compartment and the transfer compartment and simultaneously perform as a reservoir for holding a quantity of powder in the powder compartment.
