A method for rotational speed control of a feeder/mixing arm and/or a counterholding device that interacts with said feeder/mixing arm in terms of conveying technology in a filling and portioning system for food products, where a food product or components thereof is/are filled into a filling hopper, moved therein by said feeder and/or mixing arm rotated about said feeder and/or mixing arm by way of a first motor against a resistance exerted by said counterholding device, and fed to a conveyor mechanism driven by a second motor, wherein at least one machine and/or product parameter is measured in the region of said filling and portioning system and, in dependence thereof, a rotational operating speed of said first motor and/or a third motor rotating said counterholding device is controlled in an automated manner.
