Automatic Vial Powder Filling Machine

Process Operation

The sterilized powder is stored in powder hopper is agitated bypair of mechanical agitators for maintaining consistency and uniform bulkdensity. The powder wheel having eight ports rotates at the pre determinedspeed below the powder hopper with practically no clearance. Powder wheelconsist of Piston in each port and behind the powder wheel vacuum plate isprovided there is no clearance between powder wheel and vacuum plate due toback spring pressure. Precise volume of powder is sucked in to the port ofpowder wheel during vacuum according to the piston length different fill sizecan be achieved. The excess powder is doctored off by a doctor blade. Doctorblades can be adjusted from outside also without removing powder hopper. Whenpowder wheel indexes further and remain in the port due to the vacuum till itreaches just vertically above the container. The time dose of Compressed air(Nitrogen Gas), sterilized low pressure air sequentially flushes out powderfrom the port of powder wheel in to the container one by one. The filledcontainers are immediately separated on the conveyor by vial separator andmoves further for stoppering operation. (Different grooves separator can beused which depends on the container diameter or multiple dosing systems). Thesterilized, siliconised, rubber stoppers stored in the vibrator bowl moves tovibratory bowl and stacked vertically in the rubber stopper chute. Thecontainer is hold firmly between pair or timing belt to pickup rubber stopperfrom exit end of the chute. Further the container is passed between twopressing roller for tight fit fixing of rubber stopper.
