The vacuum dryer is typically used for separating a volatile liquid by vaporization from a powder, cake, slurry, or other moist material. The process is based on thermal conduction, rather than achieving the separation mechanically like in filtration or centrifugation. The humidity of the product evaporates under vacuum, by thermal conduction.

Bachiller's Vacuum Dryers type SHV offer completely heated product contacting surfaces such as the shell, the rear wall and front door, including the shaft and the mixing blades. Thus the heat transfer is maximized. The process chamber grants a minimal gap between the blades and the chamber walls, allowing an homogeneous mixing and drying process.

BACHILLER design and manufacture Paddle dryers from pilot size up to very large production scales using advances quality steels. Thanks to a unique construction know-how the most stringent specification can be met.
