Ice cream extrusion system

An ice cream extrusion system comprising a manifold unit and a nozzle unit, the manifold unit comprising:

• a first manifold having an inlet that branches into a first set of flow paths, and a first set of valves arranged to control a flow of a first ice cream mass through each flow path of the first set of flow paths;
• a second manifold having an inlet that branches into a second set of flow paths, and a second set of valves arranged to control a flow of a second ice cream mass through each flow path of the second set of flow paths, and
• a manifold interface to which all flow paths of the first and second set of flow paths lead, wherein the manifold interface comprises outlets for all the flow paths of the first and second set of flow paths, where each flow path has an individual outlet in the manifold interface;
• the nozzle unit comprising:
• a nozzle interface having inlets that are aligned with the outlets of the manifold interface, where each inlet of the inlets is arranged to receive ice cream mass from one aligned outlet of the outlets of the manifold interface;
• a set of nozzle flow paths leading from the inlets of the nozzle interface, where each nozzle flow path of the set of nozzle flow paths leads from an individual inlet in the nozzle interface, wherein all nozzle flow paths converge into a single and common nozzle flow path that forms an extrusion nozzle;
• wherein the manifold interface comprises a manifold interface surface which includes the outlets arranged to receive flow from the first and second manifolds through the manifold interface and the nozzle interface comprises a nozzle interface surface that includes the inlets, whereby in a mounted state the manifold interface surface and the nozzle interface surface are positioned to align the outlets of the manifold interface with the inlets of the nozzle interface at an abutment of the manifold interface surface and the nozzle interface surface;
• and
• wherein the manifold interface surface surrounds the outlets of the manifold interface, the nozzle interface surface surrounds the inlets of the nozzle interface.
