Nutsche Filter Dryers

Pope Nutsche Filter Dryers (also known as ANFD or Agitated Nutsche Filter Dryers) are known and used worldwide for critical high-purity separations of liquids and solids.

Agitated Nutsche Filter Dryers Overview – Ideal For Processing High-Purity Substances

Perfect for a range of high-purity applications including pharmaceuticals, biomaterials, electronics-grade materials, and fine specialty chemicals, our Nutsche filters are the preferred choice for solid-liquid separation. This crucial operation often represents the final step in the manufacturing process before packaging. Typically, the valuable solids are suspended in a solvent slurry, filtered to remove liquid, further dried, and then harvested. In specialized cases where the liquid discharge is the product, our designs ensure effective separation while retaining unwanted solids within the filter. Pope Scientific’s systems reflect the highest standards in design, materials, manufacturing, welding, finishes, components, and functionality.

Our Agitated Nutsche filter dryers excel by integrating solids filtering, washing, re-slurrying, and drying into a single vessel, enhancing process efficiency and reducing both equipment cleaning times and exposure risks. These systems feature pressure capabilities that accelerate the filtering rate and vacuum capabilities that optimize filter cake drying at reduced temperatures, further supported by optional heating and cake agitation.
