Gravimetric twin screw feeders for pharma powders
Optimize feeding for challenging materials with dust and water-resistant twin screw technology, ensuring precise and continuous handling of powders and lumpy substances in complex processing environments.

Feeds and Weighs Challenging Materials Precisely
The ZD XX FB PHARMA by Three-Tec GmbH is a gravimetric twin screw feeder designed for precise, continuous feeding of hard-to-handle materials in pharmaceutical, chemical, and biotech production. Enclosed in a dust and water-protected housing, this equipment excels in processing free to poor-flowing powders, moist, and lumpy materials. Ideal for applications such as pharmaceutical granules, protein powders, and detergent chemicals, it integrates seamlessly into continuous production lines. Featuring robust gravimetric systems, it ensures accurate dosing and reduces waste, while the twin screw design prevents bridging in challenging materials. Constructed with durable materials, it meets industry standards for reliability and cleanliness, including compliance with GMP for pharmaceuticals. This feeder offers customization options and full engineering support to cater to specific processing needs.
