HEALTH & SAFETY HYGIENE CREDENTIALS ILAPAK LTD UNDECLARED ALLERGEN AVOIDANCE BY MACHINE DESIGN By Tony McDonald, director of sales and marketing at ILAPAK UK Concerns over cross contamination on production and packaging lines are mounting following a spate of deaths linked to unlabelled allergens in food products. Food and ingredient manufacturers and packers are realising that the stakes for undeclared allergens infiltrating supply chains are too high, particularly where free-from foods are concerned. As this state of heightened awareness sets in, there is increasing interest in the hygiene credentials of packaging equipment. Switching from a dairy to a dairy-free product, for example, requires complete and thorough changeover and washdown procedures to avoid even a trace of cross-contamination. ILAPAK has many years of experience in designing form, fill, seal equipment for operation in high risk environments and has just launched a new ultra-hygienic bagmaker and flow wrapper, both of which are compliant with the USDA’s strict sanitation performance standards. This project has enabled us to identify the design principles that need to be adherred to if equipment design is to support the food industry’s increasingly rigorous approach to cross- contamination avoidance. through the machine rather than getting lodged in a crevice. An example of this might be where the guarding is bolted to the main machine frame or where there are cross members on the machine. MIND THE GAPS Where possible, surfaces should be sloped not flat to prevent debris from accumulating. On ILAPAK’s machines, all top surfaces are inclined (so that factory personnel can’t leave objects on top of machines), and all tubes and bodywork are inclined. Any joints should be fully welded rather than spot welded and there should be no plates against plates or joints against joints. If it is unavoidable to have, for example, two plates next two each other, it is preferable to insert a spacer so that any product will fall straight BITS, BOLTS AND BLIND HOLES There shouldn’t be any threads sticking out from bolts or any blind holes. Any holes should be drilled right through so that there are no recesses where dirt can build up. STRATEGIC SLOPES As food manufacturers and packers are realising that the stakes for undeclared allergens infiltrating supply chains are too high, there is increasing interest in the hygiene credentials of packaging equipment. 66 PECM Issue 42
