Increasing demand, along with Pinguin’s continuing drive for enhanced quality and improved efficiency, led the company to install the new Ishida weighers as part of its target to increase production throughput in the factory by 20%.
Case Study: Pinguin
Ishida multihead weighers are playing a critical role in helping one of the UK’s largest frozen vegetable processors and packers increase throughput by as much as 20%. Pinguin Foods UK is part of the Belgium-based PinguinLutosa group, a global leader in the supply of vegetable and potato-based top quality, easy-to-prepare products.
Increasing demand, along with Pinguin’s continuing drive for enhanced quality and improved efficiency, led the company to install the new Ishida weighers as part of its target to increase production throughput in the factory by 20%.
Typical speeds currently are around 75 packs per minute for a 1kg pack, well within the weigher’s capabilities of 90 packs per minute.
The Ishida is handling pack sizes between 125g and 2.5kg, including mixed vegetables of two, three and four varieties on the 24 head mix weigher.
Overall weighing accuracies are now running at under 0.7% deviation from the target weight compared to around 1.8% previously.
“It is vital that we keep up with the times. The high quality standards that we set ourselves and which our customers demand mean we have to invest in the latest and best equipment.” explains Chief Engineer Paul Spurrell.
The Ishidas are handling pack sizes of between 125g and 2.5kg, including mixed vegetables of two, three and four varieties on the 24 head mix weigher. In addition, the weighers can be used for special pack requirements. For example, one weigher in ‘double dump’ format is being used to pack 10kg boxes, where it has effectively doubled speed and greatly improved accuracy over the previous method.
While the Ishidas were selected initially for their speed, their superior accuracy and reliability have been equally valuable benefits. “We have had no problems with the weighers since their installation,” confirms Packing Hall Manager Steve Walton. “Another major advantage is their flexibility; we can easily switch product from line to line depending on requirements, something that was not possible with our previous volumetric and older multihead models.”
Part of this flexibility is thanks to the ease of changeover on the Ishida weighers. Product specifications including target weight are preprogrammed into the easy-to-use remote control unit for changeover at the touch of a button. The waterproof construction of each model and easy to remove change parts also mean clean down can be carried out quickly and efficiently. The weighers are in operation 24 hours a day, five days a week, with additional weekend working during busy seasons such as the run up to Christmas.

The DACS-W checkweighers feature Ishida’s unique DSP (Digital Signal Processing) chip which permits accurate signal processing under a wide range of weighing conditions, together with an Ishida built load cell that delivers high sensitivity, response and accuracy.
Pinguin Foods first proved the effectiveness of Ishida weighers with the installation of one model, and this led to them being adopted over four more lines. Now the company is planning to convert its final line to include Ishida equipment.
