1. A machine for preparing and dispensing an ice cream shop product comprising: a whipping and freezing unit with a horizontal axis (A), said whipping and freezing unit having at least one inlet for ingredients intended to constitute the ice cream shop product and one outlet for the ice cream shop product prepared, said inlet and outlet being separate from each other;a mechanism for closing the inlet and a mechanism for closing the outlet, wherein the mechanism for closing the inlet and the mechanism for closing the outlet are integrated in a single closing element;wherein the closing element comprises a first separator for closing the inlet and a second separator for closing the outlet, said separators being positioned in such a way as to guarantee, at least with the closing element in a first predetermined position, closing of the inlet and simultaneous opening of the outlet. 2. The machine according to claim 1, and further comprising a pressurized air feed mechanism for introducing pressurized air into the whipping and freezing unit, at least when the closing element is in its first predetermined position, to facilitate dispensing of the ice cream shop product prepared from the whipping and freezing unit. 3. The machine according to claim 1, wherein the first and second separators are positioned in such a way as to guarantee, at least with the closing element in a second predetermined position, closing of the outlet and simultaneous opening of the inlet. 4. The machine according to claim 3, wherein the closing element is rotatable about its own central axis (B) to move at least between said first and second predetermined positions. 5. The machine according to claim 4, wherein the first separator comprises an upper cylindrical wall having a first opening and the second separator comprises a lower cylindrical wall having a second opening. 6. The machine according to claim 5, wherein the first and second openings each have a plane of symmetry partially defined by the central axis (B) of rotation, said planes of symmetry being offset from each other by an angle of 90 sexagesimal degrees. 7. The machine according to claim 1, and further comprising a removable head, said head having a substantially flat portion forming an end wall of the whipping and freezing unit. 8. The machine according to claim 7, wherein the removable head incorporates the whipping and freezing unit inlet and outlet. 9. The machine according to claim 7, wherein the closing element is supported by the removable head. 10. A machine for preparing and dispensing an ice cream shop product comprising: a whipping and freezing unit with a horizontal axis (A), said whipping and freezing unit having at least one inlet for ingredients intended to constitute the ice cream shop product and one outlet for the ice cream shop product prepared, said inlet and outlet being separate from each other,a door equipped with a hopper for introducing ingredients into the whipping and freezing unit and a dispenser with a vertical axis (C) for dispensing small doses of product, the dispenser comprising an internal piston which slides vertically for dosing the product, a control handle for operating the piston and a plurality of levers connecting the piston and the control handle. 11. The machine according to claim 10, wherein the dispenser is in fluid communication with the whipping and freezing unit through the outlet. 12. The machine according to claim 10, wherein the hopper is in fluid communication with the whipping and freezing unit through the inlet. 13. The machine according to claim 10, wherein the hopper and the dispenser are positioned on opposite sides of a vertical axis (E) of the door. 14. A machine for preparing and dispensing an ice cream shop product comprising: a whipping and freezing unit with a horizontal axis (A), said whipping and freezing unit having at least one inlet for ingredients intended to constitute the ice cream shop product and one outlet for the ice cream shop product prepared, said inlet and outlet being separate from each other,a door equipped with a hopper for introducing ingredients into the whipping and freezing unit and a dispenser engaged in a seat, said dispenser comprising a safety device for locking the dispenser in a desired position and preventing accidental disengagement of the dispenser from its seat;wherein the dispenser comprises a shutter which closes the outlet;wherein the dispenser comprises a control lever, connected to the shutter by an arm with a curved axis and hinged at one end to a pin. 15. The machine according to claim 14, wherein the safety device comprises a plate which connects the lever to the wall, the plate also having a curved outer edge having at least a first notch and a second notch. 16. The machine according to claim 15, wherein the control lever comprises an outer tubular element and an inner tubular element coaxial with and axially slidable in said outer tubular element; said inner tubular element being moved by an outer knob located at one end of the outer tubular element and connected to the inner tubular element by a spring. 17. The machine according to claim 16, wherein the outer tubular element has a pair of slits which are diametrically opposed, the inner tubular element has a pair of pins projecting from the slits and slidable in the slits; said pins engaging in the first notch to lock the control lever in a non-operating position and keep the shutter against the outlet to close the outlet, and engaging in the second notch to lock the lever in a dispensing operating configuration, in which the shutter is distanced from the outlet and the product is dispensed.
