Abstract: An equipment for portioning out pieces of a doughy product, which pieces have a weight, which, to a great accuracy, is equivalent to a certain desired, predetermined weight. The equipment includes a pump having a feeding device and a discharge duct as well as means in a feeding unit to feed said doughy product through said feeding duct into said pump. The equipment also includes means to cut off said pieces of the product, which is discharged by the pump through said discharge duct. The pump is a lobe rotor pump. The doughy product is fed to the lobe rotor pump by a device, which provides a flow, which is somewhat larger than the discharge flow of the pump, a certain amount of the product being recirculated in said feeding unit.
