The agitated nutsche filter/dryer is a multipurpose piece of equipment that you can find in a wide range of industrial processes. Often found just downstream of a reactor or crystallizer, it has the important job of separating and isolating solids from a solvent. It has certainly come a long way since its beginning, when the nutsche filter design consisted of an open vessel that simply used suction to achieve separation. Modernization by Rosenmund started in the 1960’s, when the vessel design was enclosed for containment, enabling the introduction of pressure and agitation. The closed system further allowed for process control on parameters like temperature, pressure, pH, and agitation. In addition to expanding the unit’s operations, containment helped to protect operators from product environment as well as isolate the product from the atmosphere.
