For a German potato processing company, Gpi engineered and realized a custom additive dosing and mixing system designed for the production of prefried frozen potato products.
The system automatically doses and mixes dextrose and pyrophosphate powders, ensuring an accurate, safe and efficient addition of these additives during the production process. With this solution, our customer benefits from consistent dosing, reliable process control and improved production efficiency.
How the additive dosing system works
The additives are stored in four large dosing hoppers (144L each), all equipped with enclosed cabinets and integrated dust extraction. The hoppers feature spring-assisted lids, allowing operators to safely and easily refill the powders.
Each hopper is mounted on load cells, continuously measuring the weight so the system always knows the exact amount of powder available.
Four dosing stations control the precise supply of powder to the mixer. Each station is equipped with two electric motors and a pneumatic valve, ensuring a stable and reliable dosing process.
The powders are transported through two closed funnels that guide the material towards the jet mixer. The sealed design prevents dust formation and ensures controlled powder feeding.
Inside the jet mixer, the powders are mixed with liquid under vacuum and controlled pressure, creating a homogeneous mixture ready for the next process step.
Automated control and monitoring
Level sensors in the hoppers continuously monitor the filling level. An actuator-controlled butterfly valve regulates the powder flow to the mixer automatically, ensuring a smooth and stable process.
In addition, pressure transmitters monitor system pressure to maintain optimal operation and prevent blockages.
Efficiency and safe operation
This automated additiveline significantly improves the efficiency of the production process. Manual handling is reduced, while process control, product consistency and dosing accuracy are increased.
During operation, dust is continuously extracted through integrated filtration units, ensuring a clean working environment.
To further support safe operation, the system includes a dedicated operator platform and is designed according to ATEX requirements.
