Vertical Cone Screw Blender
The Vertical Cone Screw Blender, also known as a Nauta Mixer, is a highly efficient and gentle mixing solution designed for blending powders, granules, pastes, and even viscous materials. This blender features a conical vessel with a vertical rotating screw, which simultaneously lifts materials upward while the entire screw assembly orbits the vessel wall, promoting a three-dimensional mixing action.
This low-shear yet highly effective mixing mechanism ensures excellent homogeneity, even for materials with varying bulk densities, particle sizes, or fragile nature. It is extensively used in pharmaceutical, food, chemical, cosmetic, and plastic industries for precision mixing.
- 3D Mixing Action: Combines vertical screw rotation with orbital arm movement for complete blending.
- Gentle Handling: Low shear mixing ideal for fragile or heat-sensitive materials.
- High Mixing Accuracy: Capable of achieving mixing uniformity of 1:100,000 (CV < 5%).
- Conical Vessel Design: Promotes natural discharge and minimizes product retention.
- Wide Range of Materials: Can handle free-flowing to cohesive powders and semi-solids.
- cGMP/Hygienic Construction: Stainless steel build with mirror or matte finish for sanitary operations.
- Blending pharmaceutical excipients and active powders
- Food products like cocoa, spices, milk powder, and flour blends
- Polymer resins, colorants, and plastic compounds
- Cosmetics, detergents, and specialty chemicals
- Intermediate and bulk chemical mixing
