Cheese Producer Puts Metal Detection to the Test

Loma’s IQ3 metal detector provided Anthony Rowcliffe with a machine that can learn metal RFID tag signals and then eliminate them to focus on finding contaminants.

Loma_1Anthony Rowcliffe, a 42 year-old company that has its roots in Peckham, London, has grown over the years and is now operating out of two purpose-built BRC accredited sites at Paddock Wood in Kent, supplying over 1,000 different lines, including its own branded Clemency Hall product. The sites operate five day weeks with a same day delivery policy to a variety of major supermarkets. A combination of product integrity and a dedicated, skilled staff has enabled the company to achieve an annual turnover of £40 million, selling to diverse markets including delis, farmshops, butchers and the premium multiples.

The company prides itself on not only being able to provide quality cheeses, but also having a depth of knowledge and experience within its field, which allows it to consistently source new products and bring them to market both technically and logistically on time.

Anthony Rowcliffe is renowned for its luxury products, so maintaining an excellent reputation is key to the brand.  The company is constantly striving to ensure the highest quality standards, and as part of this drive it inspects every product meticulously prior to despatch, so the next generation IQ3 Metal Detector from Loma Systems was an obvious solution for the company.

All of Anthony Rowcliffe cheeses are individually hand-cut with wire, so it was vital that Loma provided a machine that was sensitive enough to identify the smallest metal contaminants. As the company dispatches and inspects products in trays, Loma specified a carriage track reject conveyor, designed to push reject trays down a separate conveyor system to ensure trays with contaminated product are kept separate from trays that have been inspected and found to be safe.

Anthony Rowcliffe complies with the industry standard RFID tracking system to ensure their products are tracked throughout the delivery process to guarantee they arrive at specific locations through their identifiable metal tags. These metal RFID tags can cause significant problems when going through other brands of metal detector, as the tags give off a signal, which could be misinterpreted as metal contamination in and could cause a false reject.

Loma’s innovative variable frequency IQ3 Metal Detector provided Anthony Rowcliffe with the ideal solution. Loma’s variable frequency means the machine can learn the signal given off by the metal tags and then eliminate that signal to only find contaminates that are in the products.

The machine is able to automatically calibrate to the variety of cheeses on six cutting lines. Every cheese emits a different product reading; they vary in moisture levels, salt content, density and size, therefore, frequency Loma_2levels vary enormously. With its class leading product memory offering space for 200 different products and frequency levels of between 31 and 882 KHZ, the versatility of the IQ3 provided a reliable solution for Anthony Rowcliffe. The systems Automatic Product Learn function ensures maximum sensitivity and accuracy without constant operator adjustment, resulting in one machine handling all six lines, allowing the company to avoid buying multiple machines to cope with various differing products. This function has saved the company a significant amount compared to purchasing several lesser metal detectors.

Jason Fisher, Head of Operations for Anthony Rowcliffe comments, “We chose Loma Systems due to the whole package they offered, from their knowledge, testing, product and price. We have a great relationship with Loma and it has been a pleasure to work with a company who are as quality-driven as ourselves. The machine is excellent and the variable frequency metal detector is invaluable.”

The IQ3 complies with Loma’s outstanding “designed to survive” ethos; it comes standard with the tough IP69K search head environmental protection and is highly reliable. Also the machine is easy to use, making it simpler for operators to achieve maximum functionality.

Kathy Pattenden, Cutting Room Supervisor comments, “Operating the IQ3 Metal Detector on a daily basis, has proved effortless. Having met our standards and adhered to our customers' strict code of practice, the IQ3 metal detector has recognisably increased production efficiency.” 

Anthony Rowcliffe also took advantage of Loma’s Platinum Service Contract to ensure sustained production levels and for peace of mind that should a problem occur they can receive expert support quickly and efficiently. Jason continues, “We have not used this service so far as we have had no problems, but it is good to have this safety net should any problems ever occur.”
