Claim:
A shaker for sprinkling granules, said shaker comprising: upper parts ( 3 ) defining at least one supply space ( 4 ) for granules; lower parts ( 5 ) with at least one outfeed opening ( 6 ) for sprinkling granules ( 2 ) out of said shaker ( 1 ) in a downward direction by imparting sprinkling movements to the shaker ( 1 ); at least one screen-like member ( 7 ) located at the bottom of the shaker ( 1 ), said screen-like member ( 7 ) forming a bottom for the supply space ( 4 ) and covering said outfeed opening ( 6 ); wherein said lower parts ( 5 ) of the shaker ( 1 ) define at least one lower space ( 8 ) which is located around said outfeed opening ( 6 ), said lower space ( 8 ) being closed down below by a bottom portion ( 9 ) and is provided at the top with an upper opening ( 10 ), said screen-like member ( 7 ) including downwardly directed portions ( 7 a ), said downwardly directed portions ( 7 a ) being directed downwards towards said lower space ( 8 ), a through-flow gap ( 11 ) located at an outer side of said downwardly directed portions ( 7 a ), wherein said lower space ( 8 ) communicates with the supply space ( 4 ) via said through-flow gap ( 11 ) such that granules ( 2 ) can flow from said supply space ( 4 ) down into the lower space ( 8 ), a discharge gap ( 12 ), which relative to a centre line (C) along said shaker ( 1 ) is located at an inner side of said downwardly directed portions ( 7 a ), said lower space ( 8 ) communicating with said outfeed opening ( 6 ) via said discharge gap ( 12 ) such that the granules ( 2 ) via the discharge gap ( 12 ) can pass from said lower space ( 8 ) to said outfeed opening ( 6 ), and characterized in that said screen-like member ( 7 ) is mounted movable in a vertical direction relative to said lower parts ( 5 ) of the shaker ( 1 ) which define said lower space ( 8 ) or vice versa, for being able to set said screen-like member ( 7 ) such that said downwardly directed portions ( 7 a ) are set at different distances (e.g. A or B) from said bottom portion ( 9 ) of said lower space ( 8 ) so that said lower space ( 8 ) can be brought to contain different amounts (e.g. M 1 or M 2 ) of granules ( 2 ).
