Nutsche Filter Dryer

Pope nutsche filter-dryers are known and used worldwide for critical high purity separations of liquids and solids. Products include pharmaceuticals, bio-materials, electronics grade materials, fine specialty chemicals, and many others. Our nutsche filters are preferred for this separation, a critical operation because it is often the final step in an entire manufacturing process, prior to packaging. In most applications, the solids are the product, often being highly pure crystals from reaction and precipitation, suspended in a solvent slurry. After liquid from the slurry passes through the filter, the solids may be further dried and then harvested. In other less common applications, the filtered liquid discharge is the valued product, with the solids being removed and remaining in the nutsche filter. Pope’s designs accommodate both modes. Highest quality design, materials, manufacturing, welding, finishes, components and functionality are assured.

Filter dryers provide capabilities for solids filtering, washing, reslurrying and drying in a single vessel, reducing process time and worker and environmental exposure. Pressure capability facilitates filtering rate and vacuum capability facilitates filter cake drying rate which can be additionally aided by heat and cake agitation.
