Dosing with screw feeders
DOSING FEEDERS
The ingredients in a recipe must be dosed precisely. Usual feeders are screw conveyors, rotary valves, weighing belts, etc.
For greater precision, we connect the gearmotor reducer with a frequency converter (Inverter) and through PLC automation we monitor the command to the scale. So, for a Setpoint of 350 kg, the feeder doses quickly up to 340 kg, and for the last 10 kg it doses at a slower speed. Today’s PLC automation systems as well as the good quality of the load cells, should give us an accuracy of 0.01% for a Batch of 1000 kg.
