Food & Drink Godiva’s quality control
For Godiva quality is everything, and now thanks to Russell Finex, the chocolatier has complete peace of mind With the installation of Russell Eco Self-Cleaning Filters and
Compact Sieves, Russell Finex has helped Godiva reach the highest quality standards, delivering maximum customer satisfaction every time.
Godiva Chocolatier was founded 80 years ago in Brussels, Belgium and supplies its range of high quality luxury chocolates in over 80 countries. Using only the finest chocolate and highest quality ingredients, Godiva chocolates are found in some of the most prestigious stores around the world, from Wanamaker's in Philadelphia, Pennsylvania to Nihonbashi Mitsukoshi Department Store in central Tokyo.
Godiva uses both enrobing and shell moulding processes to manufacture the various sizes and shapes of chocolates, the latter being extensively used in Europe. As with many chocolate processes, foil is commonly used to wrap chocolate because of its decorative/luxury appearance and ease of wrapping varying shapes. However, this complicates rework processes, since the foil must be removed beforehand and as a result it is not
uncommon for pieces of foil to contaminate the chocolate. To prevent this or any other foreign body contamination from entering the moulding process, Godiva has relied upon two large sieving units installed just before the chocolate depositors, which is the last stage of the process before chocolate is poured into the moulds. Although they have been reasonably effective, metal detectors would frequently alarm due to small fragments passing through the units causing costly rework. With the popularity of its chocolate increasing and with growing demand, Godiva recognised the need to review its process with the aim of gaining zero tolerance on contamination while improving production efficiency.
At the early stages of the project, Godiva identified two areas where foreign bodies could enter the chocolate. Firstly, from the rework chocolate as it is returned to the storage tanks where it is mixed with virgin chocolate. Secondly, due to the nature of chocolate processing, contamination can be introduced due to large amounts of pipework and pumps being used to transport chocolate throughout the process.
Process Solutions for Pneumatic Conveying & Dust Filtration
As a starting point, Godiva made contact with its chocolate supplier since every batch of virgin chocolate entering the Godiva plant is certified as contamination free. This resulted in a visit to one of the plants to learn how it was achieved. The systems used were fully enclosed self-cleaning filtration units supplied by Russell Finex. Peter Van Ingelghem, engineering and maintenance manager of Godiva explains: “As soon as we saw the installation it was clear that this was the solution we had been looking for.” He added: “With these systems installed there have been no reports of contaminated chocolate being delivered to our factory”.
