Versatile and flexible mixer dryer.

The Krauss-Maffei Helix Dryer HD mobile is a special variant of the helical mixer dryer HD.

It is designed for the processing of small batches that requires a precisely controlled operating environment and total product containment. Key features of the dryer are its compact dimension for mobility and the optional setup with a central drying station hosting drive unit, vacuum connection and heating/ cooling supply in combination with a stationary lifting device and multiple, mobile product vessels with vapor filters.

By connecting the product vessels with appropriate isolation valves to a mechanical separation equipment such as Krauss-Maffei Pharma Centrifuge, the product remains fully contained throughout the complete processing sequence. Different dryer vessel sizes can be connected to the central drying station for added operating flexibility. No product transfer is required from the filtration step to the drying/ mixing operation and to the final discharge point which can be provided with various high-containment devices. The entire process train can be placed on one individual floor or inside a single clean room.
