Vacuum Filters

Continuous operation, easy control and simple maintenance

By continuously developing the filtration process and technique as one of the few suppliers, SiccaDania obtained a leading position in the market. 

Vacuum filtration is considered a proven technique for separating fines from liquids. Because rotating vacuum filters can be fitted with various cake discharge systems, they are successfully applied in all branches of the process industry ranging from pharmacy to waste. 

By means of vacuum filtration starch is dewatered, water is taken out of the final starch slurry and prepared for drying.

Starch de-watering by vacuum filters is generally preferred for their continuous operation, easy control, and simple maintenance. SiccaDania vacuum filters have a state-of-the-art design and can run with full capacity flexibility, contiguous system and come with a wide range of food-grade options.

Process description 

The starch slurry is drawn onto the filter drum surface by application of vacuum through drum suction pipes. 

Starch stays behind on the surface and forms a microporous filtration layer fluid/air mixture passes this layer and is discharged through the suction pipes into the filtrate tank. Dewatered starch is continuously removed from the drum scraper knife system. The filter lining supporting the starch layer is continuously cleaned through the starch layer with a high-pressure cleaning system.
