A combination weighing system is disclosed which system is adapted to weigh out quantities of two or more different types of products and mix them together. The system includes a plurality of weighing scales divided into two groups, one group weighing out quantities of a first type of product and the other group weighing out quantities of a second type of product. A computer is provided to search the first group of scales and select a combination which contains a combined quantity of the first type of product near in weight to a predetermined fractional target weight and for searching the second group of scales and select a combination which contains a quantity of the second type of product near in weight to the difference between a target weight for both products and the weight of the product within the combination of scales selected from the first group. The selected scales of both groups empty into a common discharge chute after weighing and searching is completed. The scales of both groups are dumped at times such that both products arrive in the common discharge chute at the same time and mingle and mix with each other. Related methods are also disclosed.
