The present invention concerns a dispensing unit, comprising a tapping column (1), comprising fixed to and extending substantially normal to the top surface (11a) of a top plate (11) provided with a through opening; and forming at the top of the column an elbow. The column comprises an elongated inner channel (2) bringing in fluid communication the opening of the support plate with a tapping pinch-valve (3a, 3b) located in a tapping head (3) positioned at or adjacent the elbow at the opposite top end of the tapping column and opening to ambient atmosphere facing towards the support plate (11). The tapping pinch-valve comprises first and second jaws (3a, 3b) suitable for receiving in pinching relationship the flexible portion of the outlet end (4a) of said dispensing line and for controlling the flow of liquid therethrough. The column (1) comprises means (1b) for opening a portion of the channel (2) including the pinch valve, such that the first and second jaws (3a, 3b) can be separated from one another by a distance substantially larger than the one corresponding to the open position (d1). |
