NUTSCHE FILTER DRYER

Agitated pressure filter and vacuum dryer for solid-liquid separation

FILTERING SURFACE: from 0.07m² up to 15m²
OPERATION CAPACITY: from 19L up to 15.000L.

Agitated Nutsche Filter Dryer is high-quality equipment designed for solid-liquid separation processes, by filtration under pressure and vacuum drying, for the pharmaceutical, chemical, fine chemical and food industries.

Within the filtering applications, there are products which, due to their special hazardous or toxic characteristics, or simply to prevent cross-contamination, are more desirably treated in a hermetic way during their manufacturing process. Nutsche Filter Dryers by Bachiller have been specially designed to answer these needs, guaranteeing the obtaining of pure substances which are free from polluting elements.

Agitated Nutsche Filter Dryers by Bachiller are designed in accordance with the GMP and EHEDG standards, for all types of pharmaceutical and fine chemical applications. Our machines are validatable in sterile applications and we have special designs to install inside clean rooms.
