| 简介 |
The invention relates to a drink preparation device (1), in particular a coffee machine, with a brewing unit for leaching or dissolving a beverage substrate and [...] /or with a Milk foaming device (2), comprising a milk line (3) for transporting milk to to up-foam[...] /or heating means for heating and/or (4), wherein the milk line (3) a pinch valve (8) for adjusting the milk temperature is associated with, with which the milk line (3) in a deformation section (7) is squeezable, wherein by means of the, a about an axis of rotation (11) rotatable eccentric element (10) having, pinch valve (8) the milk temperature can be influenced, in the the eccentric element (10) in a plurality of different rotational positions can be rotated continuously or in steps, where the deformation section (7) different in rare earth resulting free flow cross-section of the flattened and is strong deformation section (7) for setting different milk flow rates differ, and that the eccentric element (10) for rotating in the different rotational positions a handle (12) for manually twisting, and/or an electric motor drive for automated rotation is associated with, the is drivable via a control unit, are stored in their memory and/or the different rotational positions and/or predeterminable via which the rotational positions are selectable user-laterally. |
