Pressure Nutsche Filter

Nutsche filtration and drying is a batch process which is carried out under vacuum and pressure in a closed vessel. Solids can be discharged directly into a dryer in dry or slurry form. In the case of a filter, the drying function can be carried out in the same vessel. The filter pressure required for separation of filtrate is through gravity and vacuum in Nutsche.

By providing the necessary connections, the Nutsche Filter can be designed to wash and dry. This design facilitates fast and easy cake discharge and aids uninterrupted service flows. This technique is very beneficial to filter and collect smaller solid particles from relatively large liquid volumes. The filter/dryer can handle a wide range of flow rates and solids loadings. The horizontal position of the filtering plate base eases the washing or further treatment of the filter cake. The Nutsche can be equipped with an optional mixer for continuous or re-suspension of solids.

Abster manufactures Pressure Nutsche Filter of varied sizes and pressure from full vacuum to 20 bar, depending on customer requirement. Abster has supplied Pressure Nutsche filter of size up to 60” diameter.

Construction of Pressure Nutsche Filter

Abster make Pressure Nutsche Filters (PNFs) are ideal for Nutsche filtration applications in pharmaceutical and sterile environments. Unlike conventional filters using PP/Polyester cloth, our Pressure Nutsche filters feature cleanable, non-fiber-releasing Sintered metallic filter discs, ensuring flawless filtration quality without product impurity risks. The nutsche filter is particularly beneficial for filtering antibiotics and vitamins in sterile rooms where ordinary centrifuges are unsuitable.

The pressure nutsche filter design allows easy handling without requiring time to time intervention from the maintenance team, saving valuable time during loading and unloading operations, especially in clean room settings. Additionally, our pressure nutsche filters come with a Davit arm arrangement in SS/Hastelloy for larger units, enhancing operational convenience.

With micron ratings ranging from 100 Micron to 1 Micron, our PNFs cater to diverse filtration needs across a wide range of products with varying filtration characteristics. The cleanable SS316L filter discs can be washed with water or appropriate solvent, ensuring longevity and cost-effectiveness compared to conventional Nutsche filters using cloth. Experience efficient and reliable Nutsche filtration with Kumar Process's advanced Pressure Nutsche Filters, designed for optimal performance and longevity in pharmaceutical and sterile environments. All of our equipment is custom designed to suit the product being manufactured with respect to cake height, liquid hold-up, CIP / SIP requirements etc.

Working Principle:

The Pressure Nutsche Filter is a closed vessel that uses filtration under pressure or vacuum to isolate solids from liquids. The closed system maintains product quality and hygiene by providing odourless, contamination-free, and non-polluting working conditions.

A typical unit consists of a dished vessel with a perforated plate. The vessel can be made completely leak-proof for vacuum or pressure service.
