About

Sharpenn Technologies manufactures Agitated Nutsche Filter Dryers (ANFD) — multipurpose equipment combining filtration, washing, re-slurrying, and drying in a single enclosed vessel. Used in pharmaceutical API manufacturing, fine chemical production, and dye/pigment processing, the ANFD eliminates separate filtration and drying equipment, reducing handling, contamination risk, and solvent exposure. Manufactured in SS316, SS316L, and Hastelloy at our Thane facility with capacities from pilot-scale to large production. Features hydraulically-operated agitator, jacketed vessel, and complete sealing for vacuum/pressure operation.

Working Principal

Step 1

Charging: Slurry from crystallizer or reactor is loaded through a top charging nozzle.

Step 1

Charging: Slurry from crystallizer or reactor is loaded through a top charging nozzle.

Step 2

Filtration: Vacuum or pressure is applied. Mother liquor passes through the sintered metal filter plate; solids are retained as cake. Agitator levels the cake for uniform thickness.

Step 3

Cake Washing: Wash solvent is added. Agitator re-slurries the cake for thorough washing. Multiple cycles possible. CW, ACW, up/down motion ensures completeness.

Step 4

Smoothing/Compression: Agitator is lowered onto cake and rotated to smooth and compress, squeezing out residual liquid.

Step 5

Vacuum Drying: Jacket is heated while vacuum is applied. Agitator breaks up cake during drying to expose fresh surfaces. Solvents recovered through vacuum system.

Step 6

Discharge: Side discharge valve opens. Agitator pushes dried product toward discharge port.

Key Features & Industry Applications

Key Features

Applications by industry

5-in-1 equipment — Filtration, washing, re-slurrying, drying, and discharge in one vessel

Pharmaceutical & API: Primary ANFD application. API isolation, washing, drying after crystallization. cGMP design available. Handles potent compounds.

Totally enclosed system — No solvent exposure, no dust emission, no contamination

Fine Chemical & Specialty Chemical: High-purity specialty chemicals, dye intermediates, fine organic compounds.

Very high solvent recovery — Closed vacuum drying recovers solvents lost in open processing

Dye & Pigment Manufacturing: Filtration and drying of dye powders and pigment cakes where color purity is critical.

Minimal contamination risk — Product stays in one vessel from slurry to dry powder

Agrochemical: Pesticide and herbicide intermediate processing under contained conditions.

Reduced manpower — Single operator can manage the entire batch cycle

Reusable sintered metal filter media — Lasts years vs. disposable filter cloths

Flexible agitator movement — CW, ACW, up, down ensures thorough washing and even drying
