Flat-bottom twin-screw feeder for precise powder feeding
Achieve precise control in powder dispensing with this flat-bottom twin-screw feeder, designed to handle both poorly flowing and free-flowing materials, ensuring consistent feed rates and accuracy critical for quality production processes.
Precisely Feeds Powders in Production Lines
The ZD 22 FB from Three-Tec GmbH is a flat-bottom twin-screw feeder designed to address precise volumetric or gravimetric feeding requirements for poorly flowing and free-flowing powders in pharmaceutical, chemical, and food industries. With its full stainless steel construction, featuring a polished finish down to Ra 0.8/Ra 0.4 µm, it ensures optimal hygiene and corrosion resistance. The feeder integrates effortlessly into your production line, whether for continuous or manual operations, and accommodates a feeding rate of 2.1-420 l/h using 22 mm metering tools. Equipped with a bottom scraper and mesh guard, the ZD 22 FB offers precise feeding essential for producing APIs, vitamin supplements, and enzyme formulations. The unit operates at speeds ranging from 1-500 min-1, supported by load cells of 60/100 kg capacity for stable operation. Certified for pharmaceutical applications, this feeder aligns with stringent GMP standards, and the modular design allows adaptation to specific process requirements.
