Aseptic Powder Filling Machine

Q: What is the filling accuracy and production speed of the Aseptic Powder Filling Machine?

The machine offers a filling accuracy of ±2–3% (depending on powder characteristics, bulk density uniformity, and environmental conditions). Single Head (APF 12S) : Up to 100 vials/minute Double Head (APF 12D) : Up to 200 vials/minute Fill range is typically 50mg to 10 grams (up to 1500mg in single dosing with change parts).

Description

Aseptic Powder Filling Machine is specialized equipment used primarily in the pharmaceutical, biotechnology, and sometimes food industries to fill sterile powders into containers like vials, syringes, cartridges, or bottles under strictly controlled, sterile conditions. The “aseptic” aspect ensures the process prevents microbial contamination, maintaining product sterility throughout filling, which is critical for injectable drugs or sensitive formulations. These machines often integrate with isolators, RABS, or cleanrooms to achieve this. Unlike standard filling machines, aseptic powder fillers handle dry powders delicately to avoid segregation, ensure precise micro-dosing, and support high-speed production while minimizing waste and enabling easy validation. They address challenges like cold-chain limitations by enabling room-temperature stable formulations.

Preparation: Containers are washed, sterilized, and depyrogenated.

Filling: Powder is supplied via a hopper with agitators for uniform flow. Dosing mechanisms dispense exact amounts into containers in a barrier system.

Closing: Stoppers or caps are applied aseptically.

Inspection: Integrated checks for fill weight, integrity, and particulates.

Output: Sealed, sterile units ready for labeling and distribution.

Working Principle of Aseptic Powder 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 wheel 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 in to 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, siliconised, 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 pickup rubber stopper from exit end of the chute. Further container is passed between two pressing roller for tight fit fixing of rubber stoppers.

FAQ for Aseptic Powder Filling Machine

What is an Aseptic Powder Filling Machine and how does it work?

An Aseptic Powder Filling Machine is specialized pharmaceutical equipment designed to fill sterile powders into vials under strictly controlled sterile conditions to prevent microbial contamination. It uses a vacuum-driven powder wheel with pistons and ports: sterilized powder is agitated in a hopper for uniform density, precisely dosed via vacuum suction, excess is doctored off, and then flushed into vials with compressed/nitrogen air. Filled vials proceed immediately to rubber stoppering, maintaining sterility throughout.

What is the filling accuracy and production speed of the Aseptic Powder Filling Machine?

The machine offers a filling accuracy of ±2–3% (depending on powder characteristics, bulk density uniformity, and environmental conditions).
