Extension of our core competence in screw feeders

The feed system is suitable for gravimetric or volumetric feeding of powders and granulates and is ideal for feed rates from 500 g/hr to 150 kg/hr. The screw feeder satisfies the stringent requirements of hygienic design.

Given the external non-intrusive agitation of its flexible hopper, the PureFeed® A discharges the product gently, ensuring optimum bulk material flow. The penetration depth and frequency of the external agitation can be conveniently set to product specific requirements. The screw feeder is available in various configurations which can be easily adjusted to the application and also handle challenging feeding tasks. Feed hoppers of various sizes are available as well as helix and nozzle auger extensions.
