The invention relates to a program controlled stirrer for producing pharmaceutical or cosmetic recipes, comprising a stirring unit (1) which consists of a stirrin g tool which engages with a mixing receptacle. According to the invention, the stirring unit is coupled to a micro-processor (5) which determines the length of stirring time and stirrin g speed at the stirring unit (1) in a program-controlled manner. The micro-processor execut es a data--processing program with the following steps: input of (11) variable data; input of (11) constant data; determination (12) of the length of stirring time and stirrin g speed in order to produce the desired amount of the recipe by combining the variable and constant data; conversion of the determined length of stirring time and stirring speed into corresponding first current or voltage values; control of the stirring unit with said firs t current or voltage values. Preferably, the size of the receptacle is inputted as variable data, whereby the data--processing program calculates the number of necessary rotations of the stirring tool using the constant data stored in the data memory, then controls the stirring unit correspondingly.
