Schematic Engineering Industries design and manufacture Barrier Isolators with integral Nutsche Filters.
Nutsche filtration is a batch filtration technique that uses vacuum and/or pressure in a closed vessel. The pressure/vacuum is used in combination with a filter plate fitted with the appropriate filter media to force liquid through the media, forming a solid bed often referred to as “cake”.
When rotated clockwise, the agitator pushes the dry cake towards the vessel wall during each rotation, thus expelling product intermittently out through the side discharge valve.
Nutsche filter/dryers can effectively perform the separation of solid matter from a liquid under pressure or vacuum, in a closed system.
