Abstract
An apparatus and method for the aerosolization of powders is disclosed. The invention includes a chamber in which a cloud of aerosolized powder is formed, the cloud having a relatively even distribution of powder particles. A Bernoulli tube may be used to extract powder from the powder cloud when the powder cloud reaches its equilibrium height. Adjustment of the air flow rate into the Bernoulli tube may be used to control the flow rate of powder out of the disclosed device.
