Spherical dryer brings a sizeable advantage to API manufacturing. Here, fresh wash liquid is sprayed on top of the solid cake taking care not to disturb the surface of the cake.

Views Read Edit View history. At this point the vessel and product may need to be cooled to agitated nutsche filter dryer ambient temperature prior to discharge. In addition a special design of interchangeable arrangement between filter cloth and multilayered sintered plate can be provided in the same equipment. Tailored to your needs. If necessary, after first filtration, wash liquor can fliter sprayed on filter bed and cake can be reslurried nuttsche manipulation of agitator movement.


Offered in a wide range of filtration area capacities upto Vapors will be generated inside the filter which can be extracted and solvent recovery can be done by installing vapor condenser and receiver.

In this process vacuum is applied on the top of the vessel through dust filter as well as on bottom of the agitated nutsche filter dryer, which will accelerate the drying process. The ANFD provides filtration under vacuum or pressure in a closed-loop system, a sealed vessel where solids can be discharged straightaway into a dryer.
