The Double Planetary Mixer (photo) is suitable for high-precision mixing, granulation and vacuum drying all in a single vessel. Powders and granules are gently blended by two rectangular planetary blades that rotate on their own axes while orbiting the mixing zone on a common axis. Atomizing spray nozzles enable controlled and spill-free addition of liquid raw materials as the mixing blades continuously ensure uniform composition and temperature throughout the batch. As a result, granulation and drying procedures can be completed in significantly shorter times compared to conventional, non-vacuum granulators and dryers. Optional features for sanitary and sensitive mixing applications include flush discharge plugs or valves, covers for use with the portable mix vessels during transport, and controls integrating the mixer with auxiliary equipment such as vacuum pumps, heating/cooling units, load cells and more. — Charles Ross & Son Co., Hauppauge, N.Y.
