* 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.
