Abstract
A system for treating meat by the application of a shock wave to the meat while the meat is in contact with a diaphragm which is substantially transparent to the shockwave, confines the meat within a tunnel. In addition, the diaphragm and shock wave generating chamber are preferably disposed above the meat.
Claims13
In a method of tenderizing meat and/or killing microbes in meat, comprising
- subjecting meat to a shock wave propagated through a incompressible fluid, wherein
- said meat is placed adjacent a first surface of a diaphragm having an acoustic impedance approximately the same as the acoustic impedance of said incompressible fluid, said incompressible fluid lying adjacent a second surface of said diaphragm, said diaphragm separating said meat from said incompressible fluid;
- and
- wherein movement of said meat is restricted when subjected to said shock wave passing through said incompressible fluid and then through said diaphragm and into said meat;
- the improvement wherein
- said meat is confined, compressed to attempt to eliminate any air pockets in the meat, and tightly sealed within a tunnel while being subjected to said shock wave.

In a method of tenderizing meat and/or killing microbes in meat, comprising
- subjecting at least one piece of meat to a shock wave propagated through an incompressible fluid, wherein
- said at least one piece of meat is placed adjacent a first surface of a diaphragm having an acoustic impedance approximately the same as the acoustic impedance of said incompressible fluid, said incompressible fluid lying adjacent a second surface of said diaphragm, said diaphragm separating said meat from said incompressible fluid;
- and
- wherein movement of said at least one piece of meat is restricted when subjected to said shock wave passing through said non-compressable fluid and then said diaphragm and into said meat;
- the improvement wherein
- the diaphragm is above the at least one piece of meat and the shock wave passes downwardly through the diaphragm and into the at least one piece of meat.
