Prior to the installation, the company used static weighing by hand, with the worker having to make quick decisions as to which two fillets to allocate to a pack. This was slow and also resulted in significant overweight. With a speed of 30 packs a minute, the new system can now deliver up to 9t of packaged fish each two-shift day. More importantly, the reduction in giveaway has enabled it to pay for itself in two years.
The Ishida solution was to design a complete integrated packing line based around a special 14-head screwfeeder weigher with scraper hoppers that uses rotating metal spirals to gently propel the sticky but fragile fillets into the hoppers.
The challenge was to get single fillets into as many weigh hoppers as possible, while preventing any weigh hopper from containing more than one fillet at a time.
