a system and method to tenderize and sterilize meat provides for uninterrupted processing of batches of meat and avoids delays and possibility of contamination of the meat . a conveyer belt carries batches of meat through liquid in a container . first and second arrays of electro - mechanical transducers are disposed in the liquid . the first array of electro - mechanical transducers is arranged facing one side of the conveyer belt and batch of meat , and the second array of electromechanical transducers is arranged facing the other side of the conveyer belt and meat . the first and second arrays of electro - mechanical transducers are oriented and controlled to simultaneously project converging shock waves of energy to and into the batch of meat . other batches of meat are placed on and picked up from the conveyer belt by feeder and pick - up conveyers to provide for continuous tenderizing and / or sterilizing without introducing contaminations .
