The invention relates to a programmable mixer for producing pharmaceutical or cosmetic recipes. The mixer includes a controller, a motor-driven mixing unit having a mixing tool engaging in a mixing vessel, and a lift unit. The lift unit induces an axial relative motion between the mixing tool and the mixing vessel to displace the mixing tool in the mixing vessel at a constant lift speed. The control method includes counting the lift strokes performed by the lift unit during an initial mixing process for each mixing period, and using the identifying data determined in the initial mixing process during a repeated mixing process. The identification data matching the recipe are read in, and the number of lift strokes per mixing period determined in the initial stirring process is used for implementing the corresponding mixing period of the repeated mixing process. |
