MY Pressure Nutsche Filter / Dryer (Triple-Combined)

Key Features:

Key Feature 1

Closed pressure-vessel design with inert-gas blanketing minimizes solvent vapor emission and protects operators when processing toxic or flammable slurries.

Key Feature 2

Three-in-one operation—pressure filtration, displacement washing and vacuum drying—eliminates intermediate transfers between separate units, shortens overall cycle time and reduces both product loss and cleaning workload.

Key Feature 3

A full-area agitator with lifting, lowering and hydraulic pressing functions ensures uniform cake formation, effective reslurry and displacement washing, and gentle automatic discharge of the dry cake without manual digging.

Key Feature 4

Heating jacket and optional heated agitator provide intensive conductive and convective heat transfer, enabling fast solvent removal, low residual moisture and stable, reproducible product quality.

Key Feature 5

Optimized internals with smooth surfaces and CIP spray nozzles facilitate validated in-place cleaning, making the unit particularly suitable for pharmaceutical, food and other hygiene-critical applications.

Process Characteristics (Technical Analysis):

The MY series is ideal for high-containment solid–liquid separation of products that require intensive washing and controlled drying. Typical duties include filtration, cake conditioning and vacuum drying of high-value intermediates and APIs, battery materials, catalyst and ion-exchange resin slurries, pigment and dye pastes, agrochemical actives, polymer additives and other solids that must be handled in a closed system with low residual solvent or moisture.

Typical Industries and Products:

Pharmaceutical & Biopharma: APIs, intermediates, highly potent compounds, sterile and aseptic products.
Fine & Specialty Chemicals: High-value intermediates, catalysts, polymer additives, functional resins.
Dyes, Pigments & Inks: Organic pigments, specialty dyes, color pastes.
Food & Nutraceuticals: High-value food ingredients, nutraceuticals and health supplements requiring low solvent residues.
Battery & New Energy Materials: Lithium, nickel–cobalt and other electrode or precursor materials requiring tight moisture and contaminant control.
Agrochemicals: Technical-grade pesticide actives and formulated products needing multi-stage washing and contained drying.

Working Principle:

The slurry is charged into the closed vessel, where pressure or vacuum filtration forms a cake on the perforated filter plate. The agitator levels and compresses the cake, then performs reslurry and displacement washing through controlled vertical and rotational movements. After washing, heating and vacuum are applied via the jacket and, if provided, the heated agitator to evaporate solvent and dry the cake. Once the target end-point is reached, the agitator is lowered and reversed to break up the dry cake and push it toward the side discharge outlet. Afterwards, the vessel can be flushed and cleaned in place, preparing the equipment for the next batch.
