Chocolate, toffee and coconut was transferring from the product onto the product belt and tray belt, this in turn was transferring onto the rollers in particular the rollers at the underside of the belt system (see picture B). The Product belt (green belt in picture) gets washed daily and during the washing the debris from the rollers would transfer back onto the product belt making washing the belt a never ending task. The rollers would get cleaned as part of the weekly cleaning schedule and this would take 2 people approximately 120 minutes to clean all rollers. To remove the build-up of chocolate, toffee and coconut it required using a soaked Scotchbrite pad and a lot of “elbow grease”. In addition to this problem the end rollers were also getting a build up of biscuit deposits on them which was causing the web tracking to drift. In the case of the tray belts this phenomenon badly effected the placing of the biscuits into the trays by the robots.
