Abstract: A meat chopper comprises a rotatable round pan and a rotatable cutter head with at least one cutter head unit. The cutter head unit comprises a base disk, at least one rotatable adjusting disk which is adjustable with respect to the base disk, and two therebetween cutters arranged diametrically. As the cutter head rotates, the cutters run radially in the basin of the round pan, while a certain distance to the round pan wall must be maintained. For this purpose, the cutters of each cutter head unit are pivotably supported at the base disk and positively locked to the adjusting disk by means of a follower device. The cutters of each cutter head unit are pressed together, and thus secured positively, in the set position with a respective lock nut. The adjusting disk can be positively locked by means of at least one locking device operable from the outside to facilitate changing or adjusting the cutters while reducing tooling costs.
