A method for producing a freezing chamber (1), a so-called whipping and freezing chamber, in ice cream making machines (2), comprises a step of producing a helical path (14) between an inner cylinder (6) and an outer cylinder (15), a step of producing a first flange (17) and a second flange (18) for closing the opposite ends of the helical path (14); in the method said steps occurring simultaneously and being carried out by means of the same working step. |
