Batch Filtration
3V Tech's Cogeim division has been a world leading supplier of Solid-Liquid Separation equipment to the pharmaceutical, fine chemical and chemical industries for 40 years.Pressure filtration is a very efficient method to separate solids from liquids, whether the product is the solid or the liquid. The required energy consumption is minimal and, in most cases, pressure filtration does not require specific temperatures, thus preserving product from any thermal shock. Pressure filtration is normally performed in pressure vessels, with the highest guarantee of absence of any product or environment contamination.
Nutsche Filter-Dryers were created for the purpose of separating solids from liquids with the added benefit of removing impurities and drying in one equipment. Thanks to the characteristics of nutsche filter - dryers, the basic operations can be carried out without exposing operators to productsand without contaminating the product itself or the environment. Cogeim has specialized solutions to keep the process fully contained during filling, discharge and maintenance operations.
Cogeim filters are specially designed for solid - liquid separation. By adding an heating system to the side walls, introducing an heated agitator and operating under vacuum conditions, they can be transformed into filter - dryers. A filter - dryer can be loaded with a concentrated slurry and discharge a dry powder.
Cogeim filter - dryers are deep bed, solid - liquid separation systems that use a filter screen to promote the development of the filter cake. Use of nitrogen above the cake and of vacuum underneith the filter mesh, can improve the filtration process. Supply of a heating fluid to the vessel and agitator jackets in combination with vacuum inside the vessel, generates the appropriate conditions for solvent evaporation and, thus, for cake drying.
