Abstract: The invention relates to a system (10) for weighing a predetermined mass of a food product, comprising an electric stepping motor (30) supported by a chassis (11) and having an output shaft, a food-product receiving member (22) which is able to move along the axis of travel between a position for receiving and a position for tipping out the food product, and an electronic control unit for controlling the electric motor. According to the invention, the receiving member is unable to move independently of the output shaft and the weighing system is configured so that, in the receiving position, the receiving member and food product apply a static torque to the output shaft, and that the electronic control unit is configured to apply a resistive torque, for a predetermined mass of the food product, to the output shaft so that when the static torque is at least equal to the resistive torque, the output shaft changes position.
