METHOD FOR SHOCK-WAVE PROCESSING OF MEAT Russian patent published in 2007 - IPC A23L3/15 A22C9/00 

FIELD: meat processing for meat tendering and controlling of bacteria therein.

SUBSTANCE: method involves exposing meat to shock wave spreading through non-compressible fluid; to do that, placing meat so that it adheres to first surface of drum-shaped diaphragm having acoustic resistance approximating that of non-compressible fluid, which adheres to second surface of drum-shaped diaphragm separating meat from non-compressible fluid; restricting displacement of meat when exposing it to shock wave penetrating through non-compressible fluid, then through drum-shaped diaphragm into meat; using shock wave generation chamber for keeping therein of non-compressible fluid having first acoustic resistance; using wave shock generation chamber in non-compressible fluid within said chamber; using drum-shaped diaphragm adhering to said chamber. Drum-shaped diaphragm has one surface adapted for contacting with non-compressible fluid when apparatus is in operating state. Drum-shaped diaphragm has opposite surface adapted for contacting with meat when apparatus is in operating position. Drum-shaped diaphragm has acoustic resistance approximating first acoustic resistance. Also, means for restricting excessive displacement of meat when the latter is exposed to shock wave is employed for performing said method.

EFFECT: increased efficiency and wider operational capabilities of method through employment thereof for meat tendering and bacteria controlling.
