Case Study: Stream Foods

Ishida Helps Deliver the Fruits of Success

The project team at Ishida Europe has devised what is claimed to be Europe’s fastest multihead weighing and packing line with a turnkey installation. This includes a 28 head model from the company’s latest generation RV-Series, currently achieving 400 packs a minute at leading fruit snacks manufacturer Stream Foods.

“We discussed our requirements with a number of multihead weigher manufacturers and our initial specification was for 200 packs per minute, but Ishida was quickly able to demonstrate that it could offer double this speed with high levels of accuracy,” explains engineering manager Peter Green.

The huge success of Stream Foods’ Fruit Bowl ranges meant that its existing weighers were struggling to keep up with demand, so the company was seeking a solution that would deliver both the speed and accuracy it required as well as a rapid return on investment.

The CCW-RV-228 is working in tandem with a 16-head RV model. The 28-head machine weighs primary packs ranging from 16 to 30g of the company’s top selling Fruit Bowl range of fruit flakes, yoghurt coated flakes and raisins and fruit shapes. The 16-head is counting these packs into groups of 5,6,8,10,12 and 20 multipacks.This combination is delivering 80 multipacks per minute for 5 packs and has reduced the demand on the three remaining multihead weighers, which were each linked to a counting eye and only capable of achieving 20 multipacks per minute.

Product giveaway is a cardinal sin and this is something we particularly wanted to address with this new installation. With the Ishida solution, we are now constantly to within a tiny fraction of the target weight.

As well as quadrupling the speed of the packing operation, accuracy levels have also been greatly improved. “Product giveaway is a cardinal sin and this is something we particularly wanted to address with this new installation,” explains Stream Foods’ factory manager Andy Spall.  “Just half a gram overweight in a 20g pack quickly amounts to a huge amount of free product over a single production run. With the Ishida solution, we are now constantly to within a tiny fraction of the target weight.”

As well as the two multihead weighers, the Ishida solution included a supply of conveyors and a flighted elevator, and incorporated Stream Foods’ existing Ishida DACS-G checkweighers along with the two bagmakers specified by the company. In addition, Ishida has supplied its pioneering IDCS II – Integrated Data Capture System – for the checkweighers, enabling Stream Foods to closely monitor its production and packing operations in order to immediately detect any problems that could affect the overall speed and efficiency of the line.

From the early stages, Ishida and Stream Foods worked very closely in the development of the project. Initial product tests in Japan were followed by a complete PDI and testing of the line prior to its installation at Stream Foods’ factory in Wisbech, meaning that the process ran extremely smoothly, with all deadlines met and the line achieving high speeds from the outset.

It was a very consultative, two-way working relationship which ensured that any potential problems could be identified and dealt with before they became an issue.

“Ultimately this line has made us far more efficient and for that reason we anticipate a fast payback on the investment,” concludes Andy. “Furthermore, as well as the speed and accuracy we needed, the line also gives us the flexibility to respond quickly to customer requirements, for example a special promotion, and also to be innovative in our product development. Indeed, new pack formats are already in the pipeline.”
