An apparatus for dispensing a liquid foodstuff, in particular milk, includes a heating device for heating the liquid foodstuff, which has a fluid path for the liquid foodstuff and an electric heater. The fluid path and heater are in thermal contact with a heat store made from a material of high thermal mass and conductivity, and the heat store is brought by the heater to an operating temperature which lies below 80° C., preferably below 70° C. The fluid path is connectable via at least one directional control valve to a flushing line via which water and/or detergent can be conducted through the fluid path for cleaning purposes. A control device is provided that is configured to heat the heat store of the heating device to a temperature above 100° C. to carry out thermal regeneration, and to open the directional control device one or more times for conducting water or detergent solution through the fluid path of the heating device heated to a high temperature.

Apparatus for dispensing a liquid foodstuff

A beverage preparation device, in particular for preparing coffee, tea or milk beverages, having a milk system for dispensing milk and/or milk froth, and having a control unit for controlling the beverage preparation device to dispense beverages portion by portion. The milk system here has a connectable conveying line to a milk container, and a milk pump which is attached to the conveying line. A first mechanical flow meter is arranged in the conveying line, this flow meter meters the volume of milk conveyed by the milk pump and is connected in terms of signaling to the control unit.

Beverage preparation device with a milk system

In order to reduce limescale formation on the continuous flow heater during operation of an apparatus for preparing freshly brewed hot beverages which has a hot water generator, which is embodied as a continuous flow heater, and a brewing apparatus, to which hot water from the hot water generator can be supplied, a controller for actuating the continuous flow heater is provided, which controller switches on the continuous flow heater for the purpose of drawing a pre-specified quantity of hot water and switches off said continuous flow heater shortly before the quantity of hot water is completely output, so that the temperature of the hot water at the output of the continuous flow heater is declining at the end of the drawing operation.
