<p>An apparatus for frothing a liquid food prod-uct is disclosed. It comprises a drive unit (1) and a frothing unit (3). The frothing unit (3) comprises a guide rod (30), which is configured along at least one section as a threaded rod (31). A frothing element (40) is in threaded engagement with the guide rod (30) and can thus be moved along a helical path on the guide rod (30). At least one dog (36, 36') is driven by the drive unit (1) in a circular motion about the longitudinal axis of the guide rod (30) and in the process entrains the frothing element (40) such that said element is driven to perform a he-lical motion on the guide rod (30). In this way, the frothing element can perform an up and down motion superimposed on the rotational motion thereof along the longitudinal direction.</p> |
