Filtration of chocolate coatings

Sweet success in the food industry for Gertrude Hawk Chocolates

To achieve the right premium taste and texture, Gertrude Hawk Chocolates uses filtration on anything chocolate coatings related. Previously, traditional wire filter baskets were predominantly used for chocolate coatings filtration, but these had serious disadvantages. The filter baskets needed to be cleaned every other day, resulting in increased production downtime. The system also had to be continuously monitored making it difficult to carry out other important tasks.


In search of a better solution, Gertrude Hawk Chocolates turned to the state-of-the-art self-cleaning Eco Filter system from Russell Finex. Supplying 4 units, the Self-Cleaning Russell Eco Filter® dismantles completely, eliminating the need to clean filtration baskets or change filter bags. With the self-cleaning design, cleaning the filter between batch runs is quick and easy. The units were customized with a Q-Tap valve to allow the sampling of freshly filtered material so the quality of the chocolate coatings can easily be monitored.

Compared to the previous basket filtration method, these high-temperature filters are saving the company a substantial amount of labor and downtime.

What our clients say

“Because the Eco Filters are so operator friendly and eliminate the need to clean filter baskets, we’re saving about 60 man hours a week with them on our 24/7 shifts. They’ve also eliminated filter blockage and pump seizures. Rather than ‘baby-sit the filters,’ our maintenance staff is now staying on top of other important tasks such as preventive maintenance.”
