Zurich / CH. (abb) The Village Bakery, based in Wrexham, Wales (UK), is one of the advanced gluten-free facility in Europe, manufacturing around 250’000 loaves a week. A major part of its process is a depositing line, which is a conveyor-based system that divides the dough into the correct weights to make various rolls and loaves. The company originally began production with a single depositor, but has optimized its operations with the addition of a second depositing line.
The Village Bakery saw potential for boosting the efficiency of the new line by improving its speed control. The company expected savings of GBP 10,000 per year, including savings on materials, such as greasing agents for the loaf tins. «The old drive was so slow and inaccurate that the machine had to start spraying the greasing agent before it «saw» each tin,» says Christien Jones, director and projects engineer.
Savings double what expected
An ABB machinery drive, with high ingress protection to IP66, was chosen. Designed to be quick and easy to install, the drive was installed by the Village Bakery’s own staff. The improved speed control brought by the new drive is saving the Village Bakery GBP 20,000 per year, double what the company had expected.
Savings are made in a number of ways, one of the more obvious being a 10 percent reduction in tin greasing agent. More accurate control means that more of the greasing agent ends up in the correct place.
The ABB machinery drive can also optimize the speed of the conveyor to match the size and throughput of different products more accurately. In this case the unit is programmed with four different speeds, leading to savings of around 25 percent in the running costs for the line.
The new depositing line has reduced downtime at the bakery, since production staff can shut down each line independently for cleaning without halting production. With IP66 protection class, frequent washdowns are no problem for the ABB machinery drive.
According to Christien Jones, director and projects engineer of The Village Bakery, the drive has been «a roaring success». He also praises the support that ABB has provided for the bakery: «The technical backup was great, and ABB is always ready to help» (Source: ABB Food + Beverage – Video: ABB via Youtube).
