Method and machine for the production of portions, including means for ejecting said portions

Machine for the production of portions of a food product, comprising:

• an extrusion device (1) suitable for delivering, continuously, a continuous strand in a vertical direction,
• a portioning device comprising at least one cutting system (3, 103), said at least one cutting system comprising cutting elements (30, 130) suitable for being moved transversally to said vertical direction between an open position wherein the strand passes between said cutting elements and a closed position for cutting the strand and forming portions (P) of the food product, each cutting system further comprising ejection means (5, 105) suitable for ejecting the forming portions (P) downwards from said cutting elements, the ejection means comprise at least one lower channel (5, 105) fluidly connected to a compressed fluid source, for injecting compressed fluid into the at least one lower channel when the cutting elements are in the closed position, wherein the at least one lower channel (5, 105) is formed in a body of corresponding cutting elements (30, 130), said at least one lower channel opens via a lower orifice (51, 151) onto a concave lower surface (32a, 132a) of said corresponding cutting element.
