Feed channel with a customized exit

A system for forming a product from a food mass, the system comprising:

• a mould member with a multitude of cavities, in which the food mass is formed into the product, and
• a feed channel that feeds the food mass into the multitude of cavities,
• wherein the feed channel has a width,
• wherein the system comprises an insert provided in the feed channel to alter the width of an exit of the feed channel, the insert is exchangeable,
• wherein the insert is tapered in a direction opposite a flow direction of the food mass through the feed channel,
• wherein the feed channel comprises an upstream edge and an opposing downstream edge, and the insert is connected to the upstream edge of the feed channel relative to a rotational direction of the mould member,
• wherein the insert has a straight section that contacts the food mass flowing through the feed channel, the straight section is located downstream of a section of the insert that is tapered relative to the flow direction of the food mass through the feed channel, and
• wherein the width of the feed channel in a region of the section of the insert that is tapered is greater than the width of the feed channel in a region of the straight section.
