The device according to claim 3, in which said shell (12, 103) is substantially shaped as a round box and said first intakes (Ia, Ic, Ie) of said first ducts (8a, 8c, 8e) and said second intakes (Ib, Id, If) of said second (8b, 8d, 8f) ducts are oriented in directions tangent to the curved side wall (12a) of the shell (12). 5. The device for supplying food according to claim 2, characterized in that said at least one pump (4a, 4c) comprises an electric motor (9) connected to said at least one impeller (11a, . . . , 11c) through motion transmission means (10). 6. The device according to claim 1, in which said pumping group comprises two pumps (400a, 400b) driven by the same electric motor by means of motion transmission means (10), each pump comprising: an impeller (11a, 11b), an intake opening (102a, 102b) and at least an intake duct that can be activated only in a given direction of rotation of the impeller (110a, 110b), said two pumps (400a, 400b) having opposite directions of rotation for the activation of the corresponding intake duct. 7. The device for supplying food or drinks according to claim 3, characterized in that the direction of rotation of said at least one impeller (11a, . . . , 11c, 110a, 110b) of said at least one pump (4a, . . . , 4c, 400a, 400b) is operatively driven by an electronic interface (5) in accordance with signals sent to said electronic interface (5) from a selection keyboard (6). 8. The device for supplying food or drinks according to claim 3, characterized in that said at least first and second output ducts (8a-8b, 8c-8d, 8e-8f, 800a, 800b) are each in fluid connection with at least a mixing device (7a, . . . , 7f). 9.
