Weight control, ejection and transportation of moist food

Completely bespoke system as to dimensions, form and material


The Challenge

Complete bespoke system – Weight control, ejection, and transportation of moist food

A biscuit and pastry manufacturer required a customised checkweighing solution for shaped dough balls within their production facility. The existing line already included large and complex machinery such as mixers, shapers, and long conveyors, meaning the new system needed to integrate seamlessly without altering the setup.

The project presented several design challenges:

  • Tailored integration – The machine had to match precise entry and exit points in the line.

  • Moist, sticky dough – The product was soft and prone to sticking, requiring special handling.

  • Variable product weights – Ranging from 1000 to 3000 g, far heavier than products typically sorted with air-jet rejection.

  • High accuracy – A scale interval of 1 g was required for consistent quality control.


The Solutions

To meet these requirements, a completely bespoke system was provided, designed to the customer’s exact specifications in terms of dimensions, form, and materials.

  • Architecture tailored to the production line – Conveyor lengths, widths, and platform height were custom-built to align precisely with existing equipment, ensuring smooth product transfer.

  • V-shaped entry conveyor – Designed to collect dough released from the overhead mixer and correctly position it on the weighing conveyor.

  • Drop-down ejection system – Instead of air jets or pushers, which were unsuitable for heavy, soft products, a drop-down reject device was implemented. The outfeed conveyor lowers via pneumatic control, gently removing non-compliant dough into a collection basket without damage.

  • Specialized belts for moist food – Food-grade belts with an open weave were chosen to prevent dough sticking. Combined with an IP66 stainless steel design, the system allows thorough wash-down with high-pressure water jets.


The Benefits

  • Seamless integration – No modification of the existing production system required.

  • Precise conveyance – Tailored architecture ensures accurate transfer to downstream machines.

  • Hygienic design – Stainless steel build and IP66 sealing allow powerful wash-down, reducing contamination risk.

  • Gentle handling – Dough balls slide smoothly without sticking or damaging the belts.

  • Effective rejection – Out-of-weight doughs are removed gently and can be reprocessed.
