Abstract: The invention relates to a continuous sterilizing system comprising a sterilizing body into which a thermal fluid is introduced for sterilizing products, the products to be sterilized being arranged in containers that circulate inside the sterilizing body, said sterilizing body being divided into different sterilization zones by means of dividing walls, and each of said dividing walls having a through-opening that is substantially the same shape as a container, such that the containers close the through-openings of the dividing walls, rendering the sterilization zones thermally isolated from one another.
