Principal of operation: gross dosage is achieved by a digital load cell to detect relative weight; subsequently the fine weight finish device are activated to reach the set weight. The gross dosage is self adjusting according to the measured weight, reducing the errors due to the variation in the volume of the dough. Second digital load cell for final weight control (gross and fine dosing) with consequent automatic adjustment of the finishing calibration. This allows to keep the average weight value constant over time.
