Inverters and geared motors power yoghurt lines
A
Lenze product story
Edited by the Engineeringtalk editorial team
Mar 9, 2009
A conveyor system for yoghurt lines at food giant Yoplait relies on 85 inverter and geared motor drives from Lenze.
With yoghurt production on three eight-hour shifts, perfect control is essential to achieve high process consistency with the sensitive milk-based products.
Lenze smd inverters meet the requirement with features that guarantee minimum downtime, and power ratings of 0.37 and 0.75kW.
They are mounted in panels above the conveyors.
Both powers have the same compact footprint, and the larger inverter is only 9mm deeper, allowing plenty of cabinet space around the drives so that no cooling fan is needed.
They can be changed by unskilled personnel and without the need to plug in a laptop.
The smds also have a pluggable memory chip that holds all the parameters and settings of the drive.
In the unlikely event of failure, the chip can be unplugged, the drive replaced and the original chip plugged back in.
The conveyor is then ready to run again, after a repair process that takes only a few minutes with no programming knowledge.
The geared motors are the Lenze Type GKR, a right-angle bevel design.
Unlike worm gears with a similar configuration, GKR gearboxes have an efficiency of 96 per cent, resulting in electricity savings of more than GBP3,000 per year for Yoplait.
Lenze geared motors are maintenance-free for 16,000 hours.
