FIMA Suspension Dryer FSD


The liquid / solid separation with filters and centrifuges is one of the most important process steps in various branches. Especially during the production of chemical or pharmaceutical substances the liquid / solid separation in combination with thermal drying will be much easier and more efficient with the FIMA Suspension Dryer compared to other process equipment.

Centrifuation and drying of products with a wide grain size spectrum and a large fraction of fine particles, i.e. with a bimodal distribution is not possible by using common processes, or only with considerable effort. During filter cake forming, the interstitial spaces of coarser particles are filled with fine-grained material, thus preventing the liquid phase from draining off during filling. Consequently, the filtrate passes through the product cake only very slowly, the ring of liquid gets higher and is reduced extremely slowly. Additionally, as the ring of liquid remains in the process chamber for a rather long time, an undesired sedimentation is caused.This is where the new filtering and drying variant comes in: Thanks to the counter impulse method, the product cake can be loosened in every process step.
