Definitions
- the invention relates to a screening device for the screening of granules, in particular moist and / or dry Granu lat, comprising a bottom, a lid and a side wall having Siebgetude, a sieve housing angeordne- te inlet opening for the granules, one on the screen housing to parent Outlet opening for the sieved granules, arranged in a sieve housing sieve and an inlet opening for transfer air.
- Sieve devices for granules in particular for a wet granulation process or a drying process in a fluidizing apparatus downstream screening process, have long been state of the art.
- the known screening devices are filled via a arranged on the lid of the screening device inlet opening for the granules and emptied via a arranged in the bottom of the screening device for a suction shoe outlet opening after the screening process. In this case he follows the transport of the granules from the inlet opening to the outlet opening, for example, via a Schwerkraftbe schickung or via a pneumatic conveying.
- Sieve devices for granules in which the z. B. moist granules is to be transferred to a dryer is that these screening devices have a large height or require and thus a spatial possibility for the realization of a equipped with a known sieve ver procedural system must be given.
- the known screening devices disadvantageous that significantly limited by the at least partially conical shape of the suction shoe of the screen housing of the known screening device by Anhaf lines or deposits of granules in the conical shaped th area (suction shoe) of the screen housing the product transfer to sieved granules becomes.
