Pinpoint Accuracy​ Of Multihead Mixing Weigher

  • 2020-11-05

Multihead weighers use a number of different weigh heads to generate precise measurements of products by calculating the weight in each weigh head. Using larger machines with more weighing heads allows the same principles to be used to provide pin-point accuracy for mix-applications. Each ingredient within a mix can be assigned to a specific section of weighing heads within the machine. 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.


Whether it is a pack of mixed sweets, mixed cereals, nut mix, or frozen vegetables, Gantan has a range of specially designed mix weighing solutions with 10, 14  and 18 heads weigher, 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. With the boost of memory bucket, multiple product mixing can be achieved with minimum number of heads with no comprise on the combination possibility.


Such accuracy means brand consistency is maintained and legal requirements when stating percentages of ingredients in a mix can be met. Manufacturers can also control the ratios of products in each portion to manage the quantity of the most expensive ingredients in any mix and to maximise profits.


Another advantage of high speed multihead mixing weigher, particularly when used in mixing applications, is the small factory footprint of the machines. When compared with a production line of individual machines that would be required to do the same job they take up far less valuable floor space. Having one machine instead of several also means maintenance and labour costs are minimised as only one person is needed to monitor the multihead weigher, while several would be needed to oversee a series of machines on the line.


Having all products processed by one weighing machine rather than a line of machines dropping product in sequence also allows products to be mixed effectively – avoiding layering of components if necessary.


A vast range of products with many different characteristics can be handled in mixed weighing. Products could vary from free-flowing components to sticky or fragile components all within same mix. To ensure they are all processed by the weighers at the highest possible speed and efficiency levels, Gantan has developed a wide range of filling systems tailored to each product component characteristic and/or pack type.


With the boost of memory bucket, multiple product mixing can be achieved with minimum number of heads with no comprise on the combination possibility.  By adopting a variety of vibration control settings, different contact parts designs, gentle handling options as well as specialist materials and angles, Gantan ensures even the most challenging products pass through the machine at the optimum rate. Where product runs vary, Gantan can also offer optional change contact parts on each section to adapt quickly to many different production challenge requirements.
