ABSTRACT:
The present invention relates to a device for discharge or outfeed of a pasty product, preferably foodstuff, from a container. A piston means (11) is brought to perform a discharge movement in a discharge direction (F) for discharge or outfeed of the product (2) from the container (3). At least one retraction or withdrawal means (24) is provided for imparting to the piston means (11) a retraction movement in a retraction direction (R) opposite to the discharge direction (F), such that the pressure from the piston means (11) against the container (3) is relieved for accomplishing non-drop operation, after discharge. At least one stroke setting or stroke determining means (30) is provided for determining the stroke of the piston means (11) and thereby, the dose volume during each discharge or outfeed of product (2) from the container (3). The stroke setting means (30) for determining a stroke of the piston means (11) is replaceably provided on said piston means (11) such that it can be replaced by another stroke setting means (30) for determining or setting another stroke.
