Dosing unit gears pump type: The dosing unit gears pump type is complementary to and interchangeable with the rollers unit. The outward rotation of the toothed rollers causes a delicate suction of the dough from the hopper. Dough is then passed throughout the nozzles without altering its texture, giving to products a lighter weight and an increased volume after baking (lady’s fingers, plum cakes, madeleines, etc.).
