Working Principle
of Aseptic Filling Machine

The sterilized powder is stored in powder hopper is agitated by pair of mechanical agitators for maintaining consistency and uniform bulk density. The powder wheel having twelve ports which rotates at pre-determined speed below the powder hopper with practically no clearance. Powder wheels consist of Piston in each port and behind the powder wheel vacuum plate is provided. There is no clearance between powder wheel and vacuum plate due to back spring pressure. Precise volume of powder is sucked into the port of powder wheel during vacuum; according to the piston length different fill size can be achieved. The excess powder is doctored off by a doctor blade. Doctor blades can be adjusted from outside also without removing powder hopper. When powder wheel indexes further and remain in the port due to the vacuum till it reaches just vertically above the container. The time dose of Compressed air (Nitrogen Gas) sterilized low pressure air sequentially flushes out powder from the port of powder wheel into the container one by one.

The filled containers are immediately separated on the conveyor by vial separator and moves further for stoppering operation.

The sterilized, siliconized, rubber stoppers stored in the vibrator bowl moves to vibratory bowl and stacked vertically in the rubber stopper chute. The container is hold firmly between pair or timing belt to pick up rubber stopper from exit end of the chute. Further container is passed between two pressing rollers for tight fit fixing of rubber stoppers.
