    moz-screenshot-30maxh=447,maxw=250,h=447,w=250The 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.

    External_spray_ringFiltration and drying are critical operations in a variety of industrial processes. These unit operations are handled separately in many applications, but can also be performed within the same unit when advantageous. The Nutsche Filter/Dryer allows for solid-liquid separation and drying operations to take place in a single process vessel.

    Centrifuge and Filter/Dryer Product Comparison

    Centrifuge and Filter Dryer comparisonThere are several filtration technologies that are used in industrial processes for liquid-solid separation.  In most cases, the solid that is obtained is the desired product, however there are instances (though less common) when the filtered liquid is the valued product.  Regardless of what material you are looking to harvest or whether your process runs as a continuous or batch operation, it can be overwhelming when you are trying to determine what equipment will best fit your process requirements.  Since the type of material being separated can vary based on particle size and product density as well as other application-specific details, there is not a “one size fits all” design that will carry out every type of filtration need.
