Abstract: A transportable plant for processing a slurry by means of a chamber filter press designed as a membrane press contains at the same time a feed system for producing the slurry and diverse machinery for influencing temperature and pressure in the interior of the chamber filter press, such as a superheated steam unit, a hot air unit and a vacuum plant, which can be connected to the interior of the plant via switchable or controllable valves. The plant is suitable particularly for producing materials which are flowable or are in pieces, for example colorants, soup and drink powders, vegetable snacks and fruit snacks and diverse pharmaceuticals and for processing sewage sludge by filtration and subsequent drying or freeze-drying of the filter cake in the chamber filter press.

Abstract: In order to dry continuously a pasty product being processed in a wet condition the product is fed via an extruder into a vacuum zone, which e.g. can be formed by a vacuum band drier. The heating of the product occurring due to the extrusion leads to a rapid expansion and drying in the vacuum. An additional feeding of heat is depending on the product no longer necessary. Accordingly the dwell time of the product in the vacuum can be reduced such that the productivity can be increased. Furthermore it is possible to operate at lower temperatures such that the quality of the product is not detrimentally influenced.
