Vacuum dryer for powders and granules
In industries dealing with heat-sensitive products, ensuring proper drying without degradation is a significant challenge. Typical issues include handling toxic or explosive materials and ensuring no product segregation or degradation during the drying process.
Efficiently dries heat-sensitive powders and granules
The Nauta conical screw dryer by Hosokawa Micron is a vacuum dryer designed for drying materials such as powders, granules, pastes, and viscous slurries. It operates with a rotating cantilevered mixing screw that conveys the product from the bottom of the vessel to the surface, enhancing convective mixing and shear. The heated jacket, which can use steam, hot oil, or water, ensures rapid heat distribution, making the drying process efficient. Ideal for heat-sensitive materials, this dryer removes vapors at low temperatures, preventing product degradation. It includes a condenser with a solvent recovery tank and a dust filter to keep the vacuum system free from contaminants. Batch volumes range from 5 to 22,000 liters, and the system is compliant with international standards such as FDA and cGMP.
