Abstract:
1. A tenderizing machine for tenderizing pieces of meat, comprising a first tenderizing roller rotating about a first axis supported in a fixed position on a structure, a second tenderizing roller rotating about a second axis parallel to said first axis and movably supported in said structure with the possibility of being separated from the first axis against the force of antagonist means due to the effect of the passage of the pieces of meat between said first and second tenderizing rollers, and drive means for rotating the first and second tenderizing rollers in opposite directions, wherein said drive means comprise a first motor operatively connected by means of a first mechanical transmission to rotate the first tenderizing roller, and a second motor operatively connected by means of a second mechanical transmission to rotate the second tenderizing roller, wherein said second mechanical transmission comprises a primary transmission to transmit the rotation from a second output shaft of a second reduction gear coupled to the second motor to an intermediate shaft supported in a fixed position on the structure, and a secondary transmission to transmit the rotation from said intermediate shaft to a second drive shaft of the second tenderizing roller aligned with said second axis, wherein said second drive shaft aligned with the second axis is supported in pivoting arms pivotable around an axis of the intermediate shaft.
