Vacuum dryer for powders and granules
Achieve precise moisture control for sensitive materials with a versatile vacuum drying solution, ideal for handling heat-sensitive, solvent-containing, or sticky products while facilitating efficient mixing and energy efficiency.
Dries and Mixes Heat-Sensitive Powders Efficiently
The Nauta Conical Screw Dryer from Hosokawa Micron is a versatile vacuum dryer designed to handle heat-sensitive materials across various industries, including pharmaceuticals, chemicals, and food production. Utilizing a high-efficiency convective drying process, this equipment gently moves products from the vessel’s bottom to the surface, ensuring uniform drying. It’s capable of handling powders, granules, pastes, and viscous slurries, making it ideal for applications like crystallization, sterilization, and de-aeration.
Batch volumes range from 5 to 22,000 liters, with custom configurations available to meet specific requirements. The Nauta dryer features an efficient heated jacket system that can be powered by steam, hot oil, or water, ensuring optimal heat transfer while maintaining low-temperature operation for sensitive materials. Integration into existing production lines is seamless, with PLC automation and remote monitoring capability for enhanced operational control.
Built with optional material choices such as stainless steel or Hastelloy, the Nauta Dryer ensures compatibility with corrosive substances. It complies with international standards, including FDA and cGMP, aiding compliance in regulated industries. Automated cleaning solutions with CIP/SIP skids facilitate easy maintenance, ensuring contamination-free processes. Hosokawa Micron also offers engineering support for tailor-made designs, making customization in processing capacities and ancillaries straightforward for diverse production needs.
