From heavy lifting to fully automatic salt dosing at Arla

During the installation of new mixers, Arla Foods required a more efficient and automated approach to salt dosing. Provak supplied a vacuum conveying system that automatically and precisely feeds salt to each mixer, reducing manual intervention, improving process reliability, and ensuring consistent product quality throughout production.

  • Company Arla Foods
  • Branch Food production
  • Setup New mixers requiring precise and flexible salt dosing
  • Characteristics High demands on automation, operational stability, and a safe working environment

The challenge

As production expanded and new mixers were installed, the need arose for a new way of handling salt. The previous process was not suitable for the new setup and led to manual workflows, heavy lifting, and a lack of space around the mixers. At the same time, there was a need for a solution that could supply multiple mixers flexibly and uniformly with salt.

The solution

The solution made it possible to vacuum transport and dose salt fully automatically from two intermediate containers, placed on load cells, to four different mixers. The system ensures precise dosing based on weight and a flexible distribution of salt to each individual mixer, completely without manual handling.

“The new solution perfectly supports our new mixers and has made salt dosing fully automatic. This provides both a better working environment and more stable operation.” – Arla Foods

Implementation

The solution was integrated into Arla Foods’ new blender installation and adapted to the existing physical setup, optimising space utilisation around the blenders.

The result

  • 100 % fully automatic salt dosing system for all new mixers
  • Elimination of heavy and manual lifting
  • More space and better flow around the production equipment
  • Stable and uniform dosing throughout the process
