Abstract: A counting and combinatorial weighing method for obtaining a collected batch of ingredients of a plurality of types, having a predetermined fractional weight. The method provides a plurality of weighing machines, each of them is for one corresponding group of different ingredients including at least one main ingredient and a plurality of incorporated ingredients. The method comprises the steps of modeling a weighing system, simultaneous weighing according to target weight values the n equal partial batches of the main ingredient within all the n associated weighing scale modules of each weighing machine. The partial batches are discharged into a discharging device, and the total weight is counted. These weighing and counting steps are repeated in succession up to k times, thus the total weight being less than the predetermined fractional weight is obtained.
