Continuous system and procedure of sterilization and physical stabilization of pumpable fluids, food, or other type of fluids, through ultra-high pressure homogenization (UHPH) includes a first heat exchanger 1 which preheats the fluid at temperature Tp between 40 and 90° C.; an ultra-homogenizer 3 through which fluid at temperature Tp is introduced at a pressure Pu between 200 and 600 MPa increasing its temperature up to a final value Tu. A second heat exchanger 4 has its cooling temperature adjusted at value Te. An aseptic tank 5 receives the cooled down fluid at value Te, from which it is pumped by sterile air pressure into an aseptic packaging machine, for the packaging of the final product.
