MEETING GOLD STANDARD for metal detection in food industry

Loma's IQ3 metal detectors and CW3 checkweighing systems enables Jardox to adhere to stringent retailer standards including the M&S code of practice for metal detection equipment

frequencies between 40kHz and 900kHz and has the ability to select the optimum frequency in seconds. Following the introduction of new ingredients Loma specified a ‘combination’ unit comprising a conveyorised IQ3 metal detector and CW3 checkweigher; 112g trays with four 28g compartments are filled, lidded, gas flushed and coded then passed through the integrated system at speeds of about 75 trays per minute before being sleeved or put into a glued skillet. A second combination unit was installed on a line producing seasoning packs which vary in size between 2.27g and 1.36kg and formed, filled and sealed on a vertical bagmaker before being inspected at speeds of approximately 40 per minute. “The checkweighers are accurate to

within a point of a gram and vital for minimising product giveaway,” continues Mabb. “They are connected to our main server, making it very easy to extract and recall production data on a daily basis for reporting programmes.” The detectors are equipped with divert

Savoury ingredients manufacturer Jardox has invested in metal detectors and checkweighers from Loma Systems to ensure it can meet stringent customer requirements


avoury ingredients manufacturer Jardox has invested in four Loma IQ3

metal detectors and two CW3 checkweighers in the past three years., primarily to meet retailer standards, in particular the stringent M&S code of practice for metal detection equipment. “The M&S code of practice for metal detectors and checkweighers is the gold standard in the food industry,” explains operations director David Mabb. “By investing in inspection equipment

that is built to that standard we can be confident it will satisfy the requirements of any retailer or manufacturer wanting us to supply them.” Jardox’s core business is supplying

savoury ingredients in bulk to food manufacturers. These are made to bespoke recipes and supplied in whatever size and format the customer requires from a 1kg bag to a 25kg pail. Rare earth magnets are Jardox’s first

line of defence. After sieving, dry ingredients are passed over the magnets

which will attract any metallic fines that may have entered the production flow from earlier milling or grinding processes. Smaller packs of up to 2.5kg are subsequently passed through Loma IQ3 metal detectors. These guard against metallic contamination from upstream equipment in the rare event of nuts, bolts and washers working loose or equipment getting damaged.

FAILSAFE COMPONENTS “The IQ3 will reliably achieve market leading detection performance,” says Loma UK sales manager Tony Bryant. “Failsafe components ensure that in the event of a machine fault or a problem with products being fed incorrectly the line is stopped and the operator alerted so there is no risk of contaminated product finding its way to consumers.” With its true variable frequency

operation the IQ3 copes well with the diverse range of products manufactured by Jardox. The detector can operate at


reject mechanisms which channel contaminated product into lockable stainless steel bins. Mabb particularly likes the bin-full indicator as it provides “a great level of reassurance that the machine is doing what it was designed to”. Another useful feature is the PVS (Performance Validation System) which is built into all Loma machine software and gives the operator a prompt to test the metal detector at regular intervals. “A bugbear of mine has always been

making sure metal detector checks are carried out with test pieces at regular intervals. The PVS means we don’t have to rely on operators to remember to carry out the test; a light indicates that they have a predetermined amount of time to perform the check before the line stops.” Jardox has recently placed an order for

a further IQ3 metal detector. “The build quality of Loma’s machines

is second to none; they are very easy to clean, robust and reliable,” concludes Mabb. “Moreover, Loma designs machines that are bespoke to our exact needs and their readiness to support us when business requirements change is always very responsive.”
