Nutsche Filter

Nutsche Filter

The Nutsche Filter is the industrial version of the well-known laboratory scale Buchner Funnel except that it is designed to operate under either on vacuum or pressure.

The Nutsche Filter is a batch filtration technique that uses a single horizontal filtering surface in vacuum and/or pressure in a closed vessel.

The filter floor consists of a densely perforated plate sufficiently strong to hold the cake weight and the pressure that is exerted on the cake's surface. There are three types of filter medium that cover the filter plate, Woven metallic mesh screen, synthetic filter cloth and sintered metallic plate.

Nutsche Filters are constructed to perform a multitude of tasks including reaction, filtration, cake washing and thermal drying on a single unit. As such these are very sophisticated machines with tight process control on parameters such as pressure, temperature and pH.

Nutsche Filters are well suited for handling flammable, toxic, corrosive and odor-noxious materials since they are autoclaved and designed for use in hazardous and ex-proof environments when extremely safe operation is required.

A typical unit consists of a dished vessel with a perforated plate. The entire vessel can be kept at the desired temperature by using a jacket through which heat transfer media can flow.
