Fluid bed and spouted equipment requires additional space to service the filter on top of the already tall equipment. Up to 2.5 meters are required above the fluid bed contraption in order to exchange 6 m long filter bags.
Glatt has now integrated horizontal filters into the fluid bed. The height of the equipment is decreased by putting the clean gas chamber to the side, resulting in no space being required above the fluid bed unit. Doors on the side of the clean gas chamber enable easy access to the filter elements. Exchanging of the filter elements is in actual fact easier from the side compared to the top.
A further advantage is the possibility to design the room at the side of the clean gas chamber as a wash room with a solid floor and tight connection to the fluid bed unit. The dust-loaden filters are handled only within this room, contaminating no other parts of the plant with the filter dust. Having removed the filter plates the complete fluid bed unit can be washed in place. With this design it is very rarely necessary to open the fluid bed unit in the production area.
The plate filter has been tested on a prototype designed GF 20 in our laboratory with the first successful application tests being carried out in March 2008. Our new GF/ProCell 25 demonstrating the plate filter will be on display at the ACHEMA 2009. This unit will be installed in our new laboratory building and will be available for tests in the fourth quarter of 2009. Hall 3, Stand O32-S42
