• Versatile Functionality: Suitable for mixing, heating, cooling, drying, and moistening.⁷
• Energy-Efficient: Low power consumption for cost-effective operation.⁸
• Consistent Mixing Quality: Maintains consistent quality at fill levels from 10 to 100%.⁹
• Wide Range of Volumes: Available in volumes from 5 to 100,000 liters.¹⁰
• High Reliability: Proven track record with thousands of customers worldwide.¹¹
• Easy Loading: Top loading via manual, Big Bag, pneumatic, or mechanical methods.¹²
• Cantilevered Mixing Screw: Rotating, free-hanging screw promotes convective particle mixing and shear.¹³

Principle of Operation:

The Nauta Mixer is a convective mixer that utilizes a combination of axial, radial, and tangential mixing mechanisms.¹⁴ Materials are loaded from the top, and the rotating, cantilevered mixing screw conveys the product from the bottom to the top.¹⁵ The screw rotates along the inner vessel wall, promoting convective particle mixing and shear.¹⁶ As particles flow downward and are recirculated by gravity, their speed increases as the vessel diameter narrows, resulting in fast and intensive mixing with low power consumption and high accuracy.¹⁷ The mixing duration depends on product characteristics and desired mixing uniformity.
