The present invention specifies a device for through-cutting of an extruded ice mass which is extruded out of a nozzle, comprising cutting means which immediately after the nozzle cuts up the extruded ice mass into product pieces which fall down on a receiving device for further processing, the cutting means comprises a first knife which is reciprocably arranged in a transverse first plane immediately after the outlet of the nozzle and arranged with a first length of stroke and a second knife which is reciprocably arranged in a plane which is parallel to the first plane and which is arranged immediately below the first knife with respect to the flow direction out of the nozzle, the second knife is arranged with a second stroke length which is smaller than the first stroke length, and means for simultaneous reciprocation of the first and the second knife. Hereby, a shearing is achieved which is more precise and commonly applicable for manufacturing of ice cream portions by an automated production of ice cream products.

A method for through-cutting of an extruded ice mass which is extruded out of a nozzle, comprising cutting means which immediately after the nozzle cuts up the extruded ice mass into product pieces which fall down on a receiving device for further processing, in which a first knife is reciprocably arranged in a transverse first plane immediately after the outlet of the nozzle and a second knife is reciprocably arranged in a plane which is parallel to the first plane and which is arranged immediately below the first knife with respect to the flow direction out of the nozzle, and in which the first knife is guided in a first transverse stroke which consists of a complete through-cutting of the ice mass, and that the second knife in a simultaneously movement is guided partly through the ice mass in an oppositely directed stroke in which the direction of movement is opposite the direction of movement of the first stroke.
