System for processing liquid foodstuff or liquid medicine with a supercritical fluid of carbon dioxide

A system for continuously processing a liquid material such as liquid foodstuff or liquid medicine with a supercritical fluid of carbon dioxide, the system comprising:

• a processing tank;
• a liquid material inlet port provided at a bottom of the processing tank for continuously supplying the liquid material into the processing tank;
• means for maintaining a surface level of the liquid material in the processing tank;
• means for changing the carbon dioxide into the supercritical fluid so that a density of the supercritical fluid is smaller than that of the liquid material;
• means for forming micro-particles of the supercritical fluid of the carbon dioxide;
• means provided at the bottom of the processing tank for continuously injecting the micro-particles of the supercritical fluid into the liquid material in the processing tank;
• a liquid material outlet port provided on a wall of the processing tank just below the surface level of the liquid material in the processing tank for continuously taking out the liquid material;
• and
• a supercritical fluid drainage port provided to the processing tank with an end placed above the surface level of the liquid material for continuously draining the supercritical fluid.
