Such accuracy means brand consistency is maintained and legal requirements when stating percentages of ingredients in a mix can be met. Whether it is a pack of mixed sweets, mixed cereals, nut mix, or frozen vegetables, Ishida has a range of specially designed mix weighing solutions with 16, 20, 24, 28 and 32 weighing heads, which enable up to eight different components to be mix-weighed so consistent amounts of each ingredient are included in each portion of the mix. They will measure out the required amount of each ingredient and then release them, in most cases simultaneously, via the multihead weigher’s discharge chute into the pack. Each ingredient within a mix can be assigned to a specific section of weighing heads within the machine. Using larger machines with more weighing heads allows the same principles to be used to provide pin-point accuracy for mix-applications. This method produces a high level of accuracy when weighing single products, and is used across a wide range of applications from snacks and confectionery to grated cheese, salads, fresh meat and poultry. These are then discharged together before the hoppers are recharged from above – ready to make the next weighing combination. A portion of the product to be weighed is fed into each weigh hopper and the machine’s computer evaluates the optimum combination of hoppers to make up the target weight. The weighers operate by having a number of hoppers arranged in columns, and each column is fitted with a weighing head.

The first multihead weigher was developed by Ishida in 1972 and although there have been many innovations and enhancements since then, the 'combination method' of how they work has remained the same. The vast majority of food products are sold by weight, so measuring out precise quantities, quickly, time after time, with as little waste or giveaway as possible, is vital, and this is exactly what multihead weighers are designed to do.
