The Nauta conical screw vacuum dryer is a universal batch dryer suitable for drying materials such as powders, granules, pastes and viscous slurries, especially when products are heat sensitive, contain solvents and are toxic or explosive.

The gentle mixing of the orbital arm and screw makes the Nauta vacuum dryer especially suitable for the production of delicate crystals such as those required in the manufacture of antibiotics.

The major benefit is output final powder product.

It has a closed process vessel with a cover and filter made out of one piece. This eliminates dead spots and offers validated automatic SIP/CIP.

There are no oils or lubricants inside the orbit arm, thus avoiding the risk of lubricant leakage. It has a sanitary mixing screw with open flights, bottom outlet for ensuring optimal emptying and is specially designed with a mechanical seal and sampler. To complete its full cGMP design, the Nauta vacuum dryer and its filter are equipped with fixed-mounted spray balls and spray nozzles for CIP/SIP.
