Without hesitation, Godiva made contact with the Russell Finex sales office in Mechelen, Belgium to discuss the project in more detail. Consequently, an in-depth risk assessment of the process was developed and, combined with Godiva’s research and Russell Finex’s experience, a design was finalised meeting all its objectives.
The chosen solution utilised a combination of both liquid filtration units and round vibratory sieves covering two critical control points within the system. This provided Godiva complete control on contamination while increasing production flexibility required to meet market demands.
The liquid filters installed were Russell Eco Self-Cleaning Filters, one after each storage tank (see figure 1). These would remove any contaminant from within the tanks that could have been introduced through rework. The units were selected due to their high flow rates and innovative self-cleaning design meaning operator involvement is kept to a minimum. The second control point was just before the depositors. A bank of Russell Compact Sieves replaced the two existing sieving units, working in tandem with the filters (see figure 2). “The Compact 400 sieves were chosen as they fitted neatly into our existing process without losing the cleanability of the depositors,” states Van Ingelghem.
The installation provided Godiva with a process that ensured contamination of foreign bodies was effectively eliminated. “Having a global recall is something that we are unable to quantify in terms of costs. However, with the new Russell systems in place we have complete peace of mind that our product is being

supplied to the highest standards.” Van Ingelghem concludes: “In fact it has actually made our metal detectors virtually redundant since we rarely ever hear them activated”.
The new installation has given Godiva complete traceability back to any contamination source. This has improved maintenance procedures whilst increasing efficiencies in the rework processes. Moving forward, Godiva has recognised the support that Russell Finex provided throughout the project whilst also offering a customer care support system that ensures a fast response to any maintenance requirements. This was particularly evident at the early stages when time was spent trying to select the optimum mesh sizes for the equipment.
