Energy efficient protein production at Arla Food Ingredients Group
Energy consuming production of whey powder at Arla Food Ingredients Group P/S in Videbæk, Denmark has been optimized by the use of Danfoss VLT® drives. It saves energy, time for project design and makes hundreds of motors run more efficiently and last longer.
In order to separate different products at the whey powder-manufacturing site at Arla Food Ingredients Group in Videbæk, the processes demand hundreds of pumps, fans, evaporators, filtration units and spray dryers. This is a highly energy consuming process. To save energy and money, Arla has chosen a concept for motor installations that includes VLT® drives from Danfoss.
Instead of designing and building new panels for motor starters, the VLT® drives (VLT® AutomationDrive FC 302 IP20) are installed in the control rooms. ”The drives are connected to every motor - new and existing - and the motors benefit from all the features of the drives. The drive systems are connected into a computerized control system, so Arla employees can control everything from the computer screen. That was not possible with the old system. We always install a Profibus card within the VLT® AutomationDrive for control purposes, which gives us the ability to access process data and information from the drives. This is a huge advantage”, says maintenance manager at Arla Food Ingredients, Knud Rahbek.
With a multi-purpose drive, like VLT® AutomationDrive, which includes harmonic filters and EMC filters for 150-metre motor cables, all the applications can be handled with one type of VLT® drive, and all the motors can be accessed from the control room.
According to Knud Rahbek, the factory also uses this concept in renovation projects. ”We simply throw out the old panels and build-up the new installation with VLT® drives in connection with distribution panels.”
