* The max. feed rates are theoretical values referring to a filling level and a motor speed of 100% each. Depending on the flow characteristics the screw filling level may decrease down to 50%, particularly if poorly flowing ingredients are metered. In case of gravimetric versions (loss-in-weight feeders) further feed rate reductions have to be taken into account because a part of the upper motor speed range is required to balance bulk density variations. To identify the optimum feeder for your specific ingredient and feed rate we recommend to make use of our automatic feeder selection program ››› "FeederScout".
