Patent ID: 8167480

Claim:
A device for processing products ( 2 ) in a process vessel ( 1 ), especially for cutting/shearing product clusters and/or materials ( 3 ) into smaller particles and dispersing them in a more or less liquid product bulk ( 4 ) or for mixing therein more or less liquid products with each other which are difficult to mix, said device having a drive unit ( 11 ) positioned outside the process vessel ( 1 ) and a processing unit ( 12 ) driven by the drive unit and positioned inside the process vessel, characterised in that the drive unit ( 11 ) drives the processing unit ( 12 ) without a shaft, and that the processing unit ( 12 ) comprises a stationary inner part ( 14 ) and, rotatable about this, an outer part ( 15 ), the inner and outer parts being rotationally symmetrical, consisting of substantially concentric rings ( 16 , 17 ) arranged with a close fit to each other and having a plurality of through shearing recesses ( 18 ) opposing each other, and lacking projecting components other than the substantially concentric rings, and the products ( 2 , 3 , 4 ) that are to be cut/shorn and/or mixed being suppliable to the area of the common centre axis ( 20 ) of the rings ( 16 , 17 ) and being induced to move out through the shearing recesses while being shorn into pieces and leave the processing unit ( 12 ) through the ring ( 17 ) of the outer part ( 15 ), said ring also contributing to rotating the products ( 2 , 3 , 4 ) in the process vessel ( 1 ) around the processing unit ( 12 ).
