Agitated Nutsche Filter Dryer Manufacturers in Amritsar

Efficient separation of solids from liquids is an important step in modern manufacturing of chemical, API and pharmaceutical products. Wet cake transfers between multiple separate units (open vacation filters, tray dryers, centrifuges, etc.) allow exposure of sensitive compounds to atmospheric oxygen and elevate the risk of contamination and unsafe exposure of shop-floor personnel to organic solvents. The control of these risks is achieved by the design philosophy of the Agitated Nutsche Filter Dryer (ANFD), which integrates liquid solid filtration, intensive cake washing, vacuum contact drying, and automated dry powder discharge in a fully enclosed, pressurized vessel.

As primary Agitated Nutsche Filter Dryer Manufacturers in Amritsar, we engineer high-integrity separation units capable of maintaining tight performance parameters under high positive pressures and deep vacuum levels. The foundation of our ANFD systems centers on an advanced, height-adjustable agitator system equipped with custom-contoured bi-directional blades. For primary filtration, the agitator is lowered to contact the filter cake and provide a smooth surface. By sealing any cracks in the filter cake and eliminating bypass of the liquid phase, filtration is enhanced. During cake washing, the agitator reverses rotation to re-mix the solid with washing solvent in order to wash the solvent impurities trapped in the cake.

Once washing finishes, the vessel transitions directly into thermal vacuum drying without breaking containment. Heating of the filter cake is performed by contacting all surfaces of the vessel inner jacket, base plate, and the hollow agitator shaft and internal channels. While the agitator is continuously rotating through the filter cake under vacuum, it exposes the product to the hot walls of the vessel and breaks up and removes solids.

Agitated Nutsche Filter Dryer Suppliers in Amritsar

Slurry dynamics change dramatically across different batch cycles, varying based on particle size distribution, crystal morphology, slurry viscosity, and thermal sensitivity. As dedicated Agitated Nutsche Filter Dryer Suppliers in Amritsar, we avoid uniform, standard-built machinery. Instead, we carefully review your specific process kinetics, solvent profiles, and batch throughput requirements to deliver a precisely targeted mechanical configuration.

Our engineering team works alongside your process specialists to select the right filtration medium, drive unit power, and automation package. Whether configuring a compact 50-liter pilot unit for clinical manufacturing or a 10,000-liter industrial unit for commercial chemical production, we supply ANFD systems designed to minimize cycle times, conserve solvent volumes, and optimize overall energy usage.

Beyond the main vessel, our systems feature hydraulic side-discharge valves that allow clean, hands-free product removal once drying reaches completion. The discharge port uses zero-dead-leg metallic sealing faces that maintain vessel pressure ratings without trapping material in unpurged recesses.
