Overview Services Technologies Systems Contact Overview Our Nutsche Filter Dryer NFD combines filtration and drying operations in a single piece of equipment, reducing capital costs and eliminating risks to operator safety and product quality. Our NFD design includes highly effective filtration and drying technologies and our sterile design NFD is ideal for the safe, contained operation in pharmaceutical applications. This eliminates the cost of separate pieces of equipment for each function and the risk of product contamination or operator exposure during product transfer. This filtration and drying in a single piece of equipment is particularly important for product quality when drying potent compounds in the pharmaceutical industry. The agitated filter also provides for efficient washing, reslurry and recrystallization. Services Process Engineering Our process engineers have extensive experience of a broad range of chemical processes that will provide added value - from process improvements and new technologies to the design of complete new process systems.

Filter features[ edit ] 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 limpet jacket, jacketed bottom dish and stirrer blade and shaft through which heat transfer media can flow. The vessel can be made completely leak-proof for vacuum or pressure service. Agitator[ edit ] A multipurpose agitator is the unique feature of this system. The agitator performs a number of operations through movement in axes both parallel and perpendicular to the shaft. When filtration is complete, the cake develops cracks causing upsets in the vacuum operation. This hinders removal of mother liquor.
