Patent ID: 8561316

Claim:
A granulation device comprising: a wet granulation unit ( 2 ), comprising a first chamber ( 4 ), for mixing a powder product with at least humidified air, the wet granulation unit ( 2 ) being effective to agglomerate the powder product and to yield agglomerates of the powder product; a dry granulation unit ( 3 ), comprising a second chamber ( 26 ), for mixing an agglomerated product exiting from the wet granulation unit ( 2 ) with at least dried air; the dry granulation unit ( 3 ) being operatively connected with the wet granulation unit ( 2 ) and being effective to dry said agglomerated product, characterized in that the wet granulation unit ( 2 ) is directly connected with the dry granulation unit ( 3 ) along a longitudinally developing axis (A) of the device, the granulation device further comprising a mobile baffle ( 35 ) located between the first chamber ( 4 ) and the second chamber ( 26 ) to separate the chambers ( 4 , 26 ) from each other, the baffle being positionable (a) in a first position wherein fluid communication between the first chamber ( 4 ) and the second chamber ( 26 ), including transfer of agglomerated product from the first chamber ( 4 ) to the second chamber ( 26 ), is blocked and (b) in a second position wherein the first chamber ( 4 ) is in fluid communication with the second chamber ( 26 ), characterized in that the device comprises a spherical cap ( 36 ) which can turn around its own rotation axis (D) and having a first portion ( 36 a ) forming the baffle ( 35 ), and characterized in that the device comprises milling means ( 34 ) operative between the chamber ( 4 ) of the wet granulation unit ( 2 ) and the chamber ( 26 ) of the dry granulation unit ( 3 ) to grind the product exiting from the chamber ( 4 ) of the wet granulation unit ( 2 ) and transfer the product to the chamber ( 26 ) of the dry granulation unit ( 3 ), and further characterized in that the cap ( 36 ) comprises a second portion ( 36 b ) adjacent to the first portion ( 36 a ), the second portion ( 36 b ) defining at least in part the milling means ( 34 ).
