  1. An Agitated Nutsche Filter Dryer is a piece of equipment used in the pharmaceutical and chemical industries for filtering active pharmaceutical ingredients (API) after crystallisation. They come in a range of sizes from 20 litres to 20,000 litres. In this blog, we will briefly explain the components and the working of an Agitated Nutsche Filter Dryer. Components of an Agitated Nutsche Filter Dryer The Agitated Nutsche Filter Dryer includes five key components. Jacketed Pressure Vessel It maintains a positive pressure or a low vacuum level and has a high sealing efficiency. High sealing efficiency It provides different process effects on the product with the help of a bi-directional agitator and an adjustable stroke. Base Filtration Element It can take different configurations and pore sizes to fit different product profiles. Heating Elements It controls the temperature of the process. Discharge Plug/Valve It is designed to recover the maximum product yield.

  2. The Working Process of an Agitated Nutsche Filter Dryer Filtration The process begins by pouring the slurry into the vessel, either in bulk or in gradual volumes. The agitator is then turned on, which begins a low-speed, high-torque mixing to ensure that the cake height doesn’t inhibit the filtration rate. A gas pressure is applied, and the separation of solid and liquid takes place. Slurry Washing The remaining filtrate and impurities are washed out once the API crystals are separated by slurry washing. It is done by adding a solvent that seeps through the product cake to separate the impurities. This is usually done more than once for the best results. Drying There are two options for drying: by pressurised gas heating or vacuum-assisted heating. Both of these methods depend on optimal heat transfer within the vessel. Heat is applied to the side wall, filter base, and agitator blades. Product Discharge Finally, the agitator forces the cake against the vessel wall and the discharge plug.
