Abstract:
A powder packing apparatus comprising:fluidizing means capable of being hermetically closed and formed with a gas inlet for receiving a gas for fluidization; a nozzle including a hole for sending out the gas and capable of hermetically closing a mouth of a container; a powder conveying path providing fluid communication between said fluidizing means and said nozzle; and a first and a second filter respectively positioned at said gas inlet of said fluidizing means and said hole of said nozzle, and each passing the gas, but filtering out powder, wherein the powder fluidized is confined between said fluidizing means and said container, said gas inlet of said fluidizing means has an area 1.002 times or more greater than an area of said hole of said nozzle for thereby causing the gas to flow at a higher rate through said hole than through said gas inlet, the powder is naturally introduced from said fluidizing means into the container via said powder conveying path and said nozzle, after the gas sent into said fluidizing means has fluidized the powder in said fluidizing means, said powder is delivered from said fluidizing means to said nozzle, and a pressure inside said fluidizing means is raised to deliver the powder from said fluidizing means to said nozzle.
