Method for treatment of meat pieces by hammer and a machine for its execution

摘要

A method and a machine for the treatment of meat pieces by hammering. The method consists in submitting the meat pieces during stopping stages in their progress along a deck (3) to one or more blows dealt by a succession of hammering members (12) whose surface provided to contact the meat piece has a plurality of pointed protrusions (15). The machine comprises a conveyor (1) providing a unitary feeding of meat pieces towards a stationary deck (3) with a plurality of pointed protrusions (4) distributed along its surface and the deck (3) having associated means providing a back-and-forth intermittent motion of the meat pieces. Above said deck (3) a plurality of independent hammering members (12) associated to respective individual actuators is arranged operable to move downwards the respective one of said members (12) till hitting a meat piece at a stage at which the latter has stopped in its travel on said deck (3) and to return the corresponding hammering member (12) to an inactive position above said deck (3).
