Rotary pan

Abstract

Described is a rotary pan ( 1 ) of the type comprising a central hollow cylindrical body ( 3 ) with end portions ( 4, 4 ′) shaped substantially like truncated cones, and mixing/deflecting means ( 7 ) attached to at least one inside surface of the pan ( 1 ) itself; the peripheral inside cylindrical surface ( 5 ) of the hollow body ( 3 ) comprises an extended zone (A) defined by a uniform distribution of through holes ( 6 ) and at least one zone (B) within the zone (A) forming an area by which the mixing/deflecting means ( 7 ) are attached or fixed to the peripheral surface ( 5 ).

1 . A rotary pan comprising a central hollow cylindrical body with end portions shaped like truncated cones, and mixing/deflecting means attached to at least one inside surface of the pan; the pan being rotatable about a horizontal axis of rotation which runs through the center of the cylindrical body, the pan being adapted to and effective to apply a coating to a plurality of products being tumbled inside the pan when the pan is rotated about the horizontal axis of rotation, a peripheral inside cylindrical surface of the central hollow cylindrical body comprising an extended zone defined by a uniform distribution of through holes, said extended zone including at least one zone within the extended zone without holes in it and forming an area at which the mixing/deflecting means is attached or fixed to the peripheral inside cylindrical surface so that, when the pan is rotated, the mixing/deflecting means effectively deflects tumbling product away from the inside cylindrical surface and closer to the horizontal axis, and the mixing/deflecting means comprising at least two separate and distinct fins, each fin being rigidly fixed or connected along its full length and covering a respective zone without holes, said two fins being discontinuous wherein discontinuous means not touching each other. 
     
     
         2 . (canceled) 
     
     
         3 . The rotary pan according to  claim 1 , wherein the at least one zone has a substantially oblong shape. 
     
     
         4 . (canceled) 
     
     
         5 . The rotary pan according to  claim 1 , wherein each fin comprises a helical profile.
