Frozen food firm to detect more contaminants

Related tags: Birds eye

Birds Eye’s Lowestoft factory has installed two free-fall laser sorters to provide enhanced quality checks on its frozen peas.

The company, part of Iglo Foods Group, says the Best Helius sorters allow far more contaminants to be detected and removed – with up to 99.5% efficiency for most defects – while reducing the overall yield losses by as much as 50%. The sorters are made by Tomra Sorting Solutions, which is represented by Stein Solutions in the UK.

In addition, overall throughput has risen by 33%. As a result, the sorters are delivering a return on investment in less than one year.

Typical contaminants

The Birds Eye factory processes and packs 36,000t of peas each year. The peas are frozen within two and a half hours of being picked and then called into the factory as required for cleaning, grading and packing. Typical contaminants that need to be removed include caterpillars, snails and stones from the soil, and pods and other parts of the pea plant.

The Helius uses laser technology to detect all types of colour and structural defects in product streams. Thanks to its patented Fluo technology, the machine is also able to spot contaminants by assessing biological characteristics that are invisible to the human eye. This makes it far more sensitive and accurate than the camera-based systems using ultraviolet light that it has replaced.
