Abstract
A method for making a batch freezing unit for containing liquid or semiliquid food products is provided. The method includes the steps of: providing a first hollow cylinder, extending along a main axis and having an outer side wall on which one grooved profile defining a continuous circuit is formed; providing a coupling member; arranging the coupling member circumferentially to, and outside, the first cylinder, so as to completely enclose the outer side wall of the first cylinder. The method includes also a step of carrying out a fully penetrating weld of an inner wall of the coupling member to the first cylinder at the grooved profile.
Claims17
A method for making a batch freezing unit for containing liquid or semiliquid food products, comprising the following steps:
- providing a first hollow cylinder, extending along a main axis and having an external side wall on which there is formed at least one grooved profile defining a continuous circuit;
- providing a coupling member, also hollow;
- disposing the coupling member circumferentially around the outside of the first cylinder, so as to completely enclose the external side wall of the first cylinder;
- the method being characterized in that it comprises a step of making a fully penetrating weld to join an inside wall of the coupling member to the first cylinder at the at least one grooved profile.
