Working Principle:

DSH nauta conical screw mixer is a convective batch mixer which is specially designed for gentle mixing of free-flowing powders or segregative pastes, slurries and liquids. It is famous for it's low-intensity mixing and highest level of mixing accuracy without product distortion.

The basic design consists of two cylindrical screws located at the vessel wall that conveys product from the bottom of the conical vessel to the product surface. The twin-screw is attached to an arm which rotates around the perimeter of the vessel causing convective mixing and shear. The speed of particles in the downward massflow when recirculated by gravity in a conical vessel increases as the vessel diameter decreases. The three actions result in a unique three dimensional mixing action.

Technical Features:

• Accurate, gentle mixing without damaging the material.
• Versatile applications: Jacket can be attached to the mixing vessel for heating or cooling. 
• Liquid spray nozzle: Spray nozzle can be equipped as an option to add liquid additives from the top. 
• Easy to discharge material with very little residue: The conical shape with the discharge port at the bottom makes discharge of material easy with a minimum of residue. 
• Sanitary design: Made by SUS304 or SUS316 stainless steel and mirror polished for high sanitary standard.
