1. A device for preparing foam from a milk-based alimentary liquid for preparing a drink, the device comprising: a container for receiving the alimentary liquid,a frame including a support for the container, the support being associated with a heater for heating the alimentary liquid contained in the container when the container is disposed on the support,a stirrer extending at least partially into the container,drive means for driving the stirrer, andcontrol means arranged for controlling the heater and the drive means, the control means arranged for heating a quantity of liquid to bring the quantity of liquid in proximity to a desired temperature level while stirring the quantity of liquid at a first speed during a first phase and for stirring the quantity of liquid at a second speed during a second phase, the control means comprising selection means for adapting the amount of heating energy supplied during the first phase as a function of the quantity of liquid, the frame being connected to a mobile cover extending above the container, wherein the drive means is disposed in the cover and the cover is mobile between a first position in which the drive means is coupled to the stirrer and a second position in which the drive means is uncoupled from the stirrer. 2. The device according to claim 1, wherein the second speed is higher than the first speed. 3. The device according to claim 1, wherein the control means is arranged for heating the quantity of liquid during the second phase. 4. The device according to claim 1, wherein the selection means includes a plurality of control keys, each of the keys corresponding to the supply of a quantity of energy for a determined quantity of liquid. 5. The device according to claim 1, wherein the container is removably mounted on the support. 6. The device according to claim 1, wherein the container is associated with a cover and the cover carries the stirring means. 7. The device according to claim 1, wherein the stirrer is formed by a rod including a stirring head at its distal end. 8. The device according to claim 7, wherein the rod is rotatably mounted in the cover. 9. The device according to claim 7, wherein the stirring head extends in proximity to the bottom of the container. 10. The device according to claim 1, wherein the drive means is coupled to the stirrer by a friction coupling. 11. The device according to claim 1, comprising locking means for holding the cover respectively in the first and second positions. 12. The device according to claim 1, wherein the control means is disposed in the frame and the control means is connected to control keys arranged on one surface of the cover. 13. The device according to claim 1, wherein the drive means further includes a motor with two directions of rotation. 14. A device for preparing foam from a milk-based alimentary liquid for preparing a drink, the device comprising: a container for receiving the alimentary liquid,a frame including a support for the container, the support being associated with a heater for heating the alimentary liquid contained in the container when the container is disposed on the support,a stirrer extending at least partially into the container,drive means for driving the stirrer, andcontrol means arranged for controlling the heater and the drive means, wherein the control means includes temperature detection means and the control means is arranged for controlling the drive means in accordance with at least two speed levels as a function of the temperature level detected, and the frame is connected to a mobile cover extending above the container, wherein the drive means is disposed in the cover and the cover is mobile between a first position in which the drive means is coupled to the stirrer and a second position in which the drive means is uncoupled from the stirrer.
