  "claims": [
    "1. A machine for making liquid or semi-liquid food products, comprising: a processing chamber for processing a basic mixture and including a stirrer and a thermal treatment system for the basic mixture, operating in conjunction with one another to convert the basic mixture into a liquid or semi-liquid product; a dispensing device including a dispensing nozzle connected to the processing chamber to deliver the liquid or semi-liquid product, a support having a housing seat for housing a receiving container; a movement mechanism suitable for vertically moving the support between a vertical position away from the dispensing nozzle and a vertical position close to the dispensing nozzle; a rotation mechanism suitable for rotating the housing seat about a vertical axis; wherein the movement mechanism comprises a slide, which the support is mechanically connected to, and at least one guide for vertically guiding the slide; wherein the movement mechanism comprises: a cantilevered element which is cantilevered from the slide, and a first shaft supported by the cantilevered element and connected to the support; a first motor connected to the first shaft and supported by the cantilevered element; wherein the rotation mechanism comprises a second shaft and a second motor; wherein the second shaft is rotatable independently of the first shaft.",
    "2. The machine according to claim 1, further comprising an electronic drive and control unit and wherein the electronic drive and control unit is operatively connected to the movement mechanism and to the rotation mechanism to drive the movement mechanism and the rotation mechanism.",
    "3. The machine according to claim 1, wherein the support is rotatable relative to the slide about a vertical axis, between a spaced-apart position and a close-together position.",
    "4. The machine according to claim 1, wherein the movement mechanism comprises a conrod, the conrod being slidably connected, at a first end, to the slide.",
    "5. The machine according to claim 4, wherein the conrod is also connected, at a second end opposite to the first end, to a shaft of an actuator.",
    "6. The machine according to claim 1, comprising at least one actuator to drive the movement mechanism and the rotation mechanism.",
    "7. The machine according to claim 1, comprising a plurality of supply containers containing the basic mixture and connected to the processing chamber to deliver the basic mixture into the processing chamber.",
    "8. A method for making and dispensing a liquid or semi-liquid product, comprising the following steps: providing a machine comprising: a processing chamber for processing a basic mixture and including a stirrer and a thermal treatment system for the basic mixture, operating in conjunction with one another to convert the basic mixture into a liquid or semi-liquid product; a dispensing device including a dispensing nozzle connected to the processing chamber to deliver the liquid or semi-liquid product, a support having a housing seat for housing a receiving container; a movement mechanism suitable for vertically moving the support between a vertical position away from the dispensing nozzle and a vertical position close to the dispensing nozzle; a rotation mechanism suitable for rotating the housing seat about a vertical axis; wherein the movement mechanism comprises a slide, which the support is mechanically connected to, and at least one guide for vertically guiding the slide; wherein the movement mechanism comprises: a cantilevered element which is cantilevered from the slide, and a first shaft supported by the cantilevered element and connected to the support; a first motor connected to the first shaft and supported by the cantilevered element; wherein the rotation mechanism comprises a second shaft and a second motor; wherein the second shaft is rotatable independently of the first shaft; placing the basic mixture inside the processing chamber; setting the stirrer in rotation and simultaneously thermally treating the basic mixture inside the processing chamber to make the liquid or semi-liquid product from the basic mixture; preparing a receiving container in the housing seat of the support; dispensing the liquid or semi-liquid product through the dispensing nozzle and, at the same time, moving the support vertically and rotating the seat.",
    "9. The method according to claim 8, wherein the rotating the seat and moving the support vertically are at least partly simultaneous.",
    "10. The method according to claim 8, wherein the step of dispensing the liquid or semi-liquid product through the dispensing nozzle and, at the same time, moving the support vertically and rotating the seat comprises the following step: setting the seat in rotation and simultaneously moving the support vertically from a top down.",
    "11. The method according to claim 10, comprising, before the step of setting the seat in rotation and simultaneously moving the support vertically from the top down, a step of moving the support vertically from a bottom up.",
    "12. The method according to claim 11, wherein the step of dispensing the liquid or semi-liquid product through the dispensing nozzle and, at the same time, moving the support vertically and rotating the seat comprises, before the step of moving the support vertically from the bottom up, a step of moving the support in a horizontal plane from a horizontal position where the support is spaced apart from the dispensing nozzle to a horizontal position where the support is close to the dispensing nozzle.",
    "13. The method according to claim 12, wherein the step of moving the support in a horizontal plane from a horizontal spaced-apart position where the support is spaced apart from the dispensing nozzle to a horizontal close-together position where the support is close to the dispensing nozzle comprises a step of causing the support to rotate about a vertical axis between the horizontal spaced-apart position and the horizontal close-together position.",
    "14. The method according to claim 10, wherein the step of dispensing the liquid or semi-liquid product through the dispensing nozzle and, at the same time, moving the support vertically and rotating the seat comprises, after the step of moving the support vertically from the top down, a step of moving the support in a horizontal plane from a horizontal position where the support is close to the dispensing nozzle to a horizontal position where the support is spaced apart from the dispensing nozzle.",
    "15. The method according to claim 14, wherein the step of moving the support in a horizontal plane from a horizontal position where the support is close to the dispensing nozzle to a horizontal position where the support is spaced apart from the dispensing nozzle comprises a step of rotating the support about a vertical axis between the horizontal close-together position and the horizontal spaced-apart position."
