Belgian chocolatier Godiva has taken significant steps to safeguard the quality of its luxury chocolates by implementing advanced self-cleaning filtration technology in its production process.

Established in Brussels in 1926 by Belgium chocolate maker Pierre Draps, Godiva is known worldwide, with its premium products sold in over 100 countries.

The company faced a common industry challenge: the potential for small pieces of foil to enter the chocolate during rework processes.

Foil is widely used for its luxury appeal and adaptability in wrapping chocolates of various shapes. However, removing foil wrappers during rework poses a risk of contamination in the production line, as fragments can inadvertently mix with the chocolate.

To address this, Godiva identified two critical points within its chocolate manufacturing process wher contaminants might enter and sought a robust solution to maintain product purity.

After observing filtration technology in action at a supplier’s facility, Godiva collaborated with filtration specialists Russell Finex to implement a comprehensive system aimed at tackling these risks.

Addressing the contamination risks

Following a rigorous risk assessment, Russell Finex recommended a combination of in-line filtration units and circular vibratory sieves to address both contamination points.

The first stage involved installing two Self-Cleaning Russell Eco Filter® systems immediately after each storage tank, which intercept any contaminants that could have entered the chocolate from rework. These self-cleaning filters, designed for high flow rates, also help to reduce the need for operator intervention, streamlining the process while enhancing safety.

In the final stage before chocolate reaches the depositors, Godiva replaced its existing sieving units with a bank of compact vibratory sieves, optimised to work alongside the new in-line filters.

According to Peter Van Ingelghem, Godiva’s Engineering and Maintenance Manager, the Russell Compact 400 sieves were chosen for their seamless integration into the existing process, preserving the “cleanability” of the depositors without adding complexity to the system.

With self-cleaning filtration technology now embedded in its chocolate production, Godiva can ensure that every bite remains pure and indulgent for consumers, free from the risk of foil contamination.
