The PureFeed DP-4 is a gravimetric feeder that can accurately meter dry pharmaceutical, nutraceutical, and cosmetic powders at feed rates as low as 20 g/hr. The feeder can perform jet milling, continuous blending, medical-grade-plastics compounding, packaging, coating, and ingredient weighing. The key to its success is a speed-controlled, inert ceramic feed disk. Positioned at the base of a cylindrical electropolished stainless-steel material-storage chamber, the disk rotates to discharge tiny amounts of material precisely, continuously and pulsation-free over a 20-g to 2-kg feed-rate range. Since the feed disk separates the material supply from the discharge point, there is no compaction and no chance of flooding.
