Cooling system and appliance for producing cooled edible products
Provided is a cooling chamber, cooling system and an appliance for producing cooled edible products, such as ice cream, sorbets, frozen yogurt, foamed cooled drinks, etc.
1. A cooling chamber having a cylindrical shape with an axis defined between end walls and a circumferential axial wall, and comprising
a cooling fluid entry port and a cooling fluid exit port connectable to respective source and drain of a cooling fluid;
a heat exchanger within walls of the cooling chamber for circulating the cooling fluid between the source and the drain, and comprising
an entry manifold element, defined as a cavity within one of the end walls, being associated and in fluid communication with said entry port, and
an exit manifold element, defined as a cavity within said one of the end walls, being associated and in fluid communication with said exit port,
the entry manifold element and the exit manifold element being in fluid communication with at least two conduit systems defining at least two cooling fluid flow paths between the entry and exit manifold element,
said conduit systems being constituted by consecutive conduit segments, the conduit segments being bores or cavities formed within the walls of the cooling chamber,
each of the at least two conduit systems comprises
a plurality of axial segments spanning the distance between said two end walls and defined as bores in the circumferential axial wall, and a plurality of peripheral segments formed in the end walls, each of said peripheral segments linking two axial segments that are consecutive in said flow path.
2. The cooling chamber of claim 1 , comprising two conduit systems in opposite portions of the circumferential wall.
3. The cooling chamber of claim 2 , wherein each of said portions is half the circumference.
4. A cooling system comprising a cooling chamber having a cylindrical shape with an axis defined between end walls and a circumferential axial wall;
a source and a drain of cooling fluid;
a heat exchanger within walls of the cooling chamber;
said heat exchanger being configured for circulating the cooling fluid between the source and the drain, and comprising
a cooling fluid entry port and a cooling fluid exit port,
an entry manifold element defined as a cavity within one of the end walls, being associated and in flow communication with the entry port, and
an exit manifold element defined as a cavity with said one of the end walls, being associated and in flow communication with the exit port,
the entry manifold element and the exit manifold element being in fluid communication with at least two conduit systems defining at least two cooling fluid flow paths between the entry and exit manifold elements, said conduit systems being constituted by consecutive conduit segments, the conduit segments being bores or cavities formed within the walls of the cooling chamber,
each of the at least two conduit systems comprises
a plurality of axial segments spanning the distance between said two end walls and defined as bores in the circumferential axial wall, and
a plurality of peripheral segments formed in the end walls, each of said peripheral segments linking two axial segments that are consecutive in said flow path.
5. The cooling system of claim 4 , wherein the at least two conduit systems comprise two conduit systems in opposite portions of the circumferential wall.
6. The cooling system of claim 4 , wherein each of said portions is half the circumference.
