The Rollfit®-System - R&W Filtertechnik
The innovative Rollfit® system combines the process steps of filtration and drying in one and the same facility. In particular, solid-liquid separation and the subsequent drying operation can be carried out in the very same facility and without having to manipulate or handle the product in any way.
The suspension is pumped into the Rollfit® and, thereafter, filtrated until a solid filter cake remains in the facility. Next, this is immediately thermally dried in a vacuum, there and then, until the desired level of residual moisture is achieved.
