Unit for dosing a confectionery mass including a reversing rotary piston

A unit for dosing a confectionery mass, comprising:

• a base body;
• a dosing chamber, the dosing chamber being arranged in the base body, the dosing chamber being designed and arranged to contain a confectionery mass;
• a rotary piston,
• the rotary piston being arranged in the base body,
• the rotary piston being rotatingly driven with respect to the base body,
• the rotary piston being designed and arranged to be reversingly driven to alternatingly fill the dosing chamber with confectionery mass and to remove confectionery mass from the dosing chamber,
• the rotary piston having a filling cycle for filling the dosing chamber with confectionery mass, the rotary piston during the filling cycle being rotatingly driven in a first direction of rotation,
• the rotary piston having a removing cycle for removing the confectionery mass from the dosing chamber, the rotary piston during the removing cycle being rotatingly driven in a second direction of rotation, the second direction of rotation being opposite to the first direction of rotation, and
• the filling cycle and the removing cycle forming one complete working cycle of the rotary piston, the one complete working cycle consisting of the filing cycle and the removing cycle;
• an outlet valve, the outlet valve including a closing part, the closing part being designed and arranged to be rotatingly driven with respect to the base body and the rotary piston to alternatingly reach a closed position and an opened position, the dosing chamber being defined by the base body, the rotary piston, and the closing part;
• and
• an outlet opening, the outlet opening being designed and arranged to discharge the confectionery mass from the unit, the outlet opening in the closed position of the closing part not being connected to the dosing chamber, the outlet opening in the opened position of the closing part being connected to the dosing chamber.
