  • Patent number: 5869123
    Abstract: A method of continuously de-activating enzymes, sterilizing or deodorizing a liquid material such as liquid foodstuff or liquid medicine with a supercritical fluid of carbon dioxide. The method includes the following steps: 1) the liquid material is continuously supplied from an inlet at a bottom of a processing tank; 2) micro-particles of the supercritical fluid of the carbon dioxide are formed so that a density of the supercritical fluid is smaller than that of the liquid material; 3) the micro-particles of the supercritical fluid are injected continuously into the liquid material from another inlet at the bottom of the processing tank; and 4) the liquid material and the supercritical fluid are separated into different phases at the top of the processing tank and are taken out of the processing tank separately.
