Dry Powder Filling Machine for Glass Bottles

Glass bottles are fed through an infeed system and positioned using a bottle-lifting and neck-holding mechanism. The machine then dispenses a precise amount of powder using vacuum-air pressure, auger, or servo-controlled dosing technology. Filled bottles are transferred via conveyor or star wheel for further processing such as stoppering or capping. Safety systems like “No Bottle – No Fill” prevent wastage.

These machines typically achieve filling accuracy of ±1% to ±2%, depending on powder characteristics, fill volume, and controlled environmental conditions (such as humidity). Consistent dosing helps meet regulatory weight requirements and reduces product giveaway.

Output varies by model and configuration. Many automatic Dry Powder Filling Machines for Glass Bottles can handle from 50 to over 200 bottles per minute, influenced by factors such as powder type, fill volume, and bottle size.

The machine is suitable for free-flowing and semi-free-flowing dry powders. It accommodates a range of round glass bottle sizes and neck diameters. Vibratory systems or specialized funnels assist with powders that tend to bridge or flow poorly, ensuring reliable performance at higher speeds.

Product-contact parts are made from stainless steel SS316 or SS316L for corrosion resistance and easy sterilization. The machine frame is typically stainless-steel finished and designed to comply with cGMP standards, supporting cleanroom use and regulatory requirements in pharmaceutical manufacturing.

Key benefits include high dosing accuracy, reduced powder wastage, clean bottle exteriors (thanks to neck-holding systems), increased production speed, lower labor dependency, hygienic design, and easy changeovers. These features improve efficiency, product quality, and cost-effectiveness compared to manual filling.

Contact parts are designed for easy removal and are compatible with cleaning, autoclaving, or sterilization processes. The hygienic stainless-steel construction and accessible design help minimize downtime during batch changeovers and routine maintenance.

Standard safety features include “No Bottle – No Fill” systems to prevent powder loss, overload protection, and mechanisms that reduce the risk of bottle breakage. These interlocks enhance operational reliability and protect both the product and the equipment.

Yes. Machines are available with different filling heads, powder wheels, and configurations to suit specific fill volumes or higher speeds. They can be integrated with bottle washing, sterilization, stoppering, capping, and labeling equipment to create a complete powder packaging line for glass bottles.
