MSE Hiller has recently installed several solids liquid separation units into the food industry, many for household names such as Branston, Burts, Diageo, Heinz, Pepsico, Quaker Oats, Kellogg’s, Kettle, Walkers and 4U Fresh Produce.
The Hiller Decapress units are able to process high flow rates from a small footprint producing a high dry solids cake and a cleaned effluent which is easy to dispose of.
Following a competitive tender for their production facility at Trafford Park in Manchester, Kellogg’s installed a DP37-422VABD Hiller Decapress unit to process up to 14m3/hr of water treatment sludge from a combination of DAF and biological processes. The machine which operates without polymer addition is able to achieve a dry solids cake of around 20-22% ds.
Burts Chips installed a DP37-422VABD Hiller Decapress unit to process up to 10m3/hr of combined plant waste water. The machine which operates without polymer addition is able to achieve a dry solids cake of around 30-40% ds reducing effluent disposal costs at their Plymouth site.
Starch is notoriously high in BOD and its removal from effluent means that it can significantly save on effluent disposal costs vis the mogden formula as well as providing a saleable product.
Potato starch solids recovery in the crisp industry are typically crumbly powdery white solids discharged at 60-70% dry solids and Hiller has installed machines worldwide in this sector including China, Egypt, Pakistan, Poland, Thailand, Turkey and the USA.
Meanwhile on potato chip processing lines and potato processing plants peel waste can be recovered and dewatered to a stackable transportable mass at 22-30% ds.
Soil, waters, muds, sands and silts can be dewatered to 45-60% ds.
New developments for the food sector include three-phase DecaOil machines installed where oil, water and solids need to be recovered in a single process stage, often at elevated temperatures. Olive oils, fish oils and mineral oils are just three examples of this.
Finally, juices such as apple, beetroot, carrot, elderflower, grape, ginger, garlic and orange are processed on Hiller two-phase Decafood machines which produce high-quality food grade products.
With enclosed, highly automated CIP systems in food grade designs and capacities ranging from 0.2 to 120m3/hr the Hiller DecaPress, DecaFood and DecaOil centrifuges are certainly starting to rise and shine in the food processing industry sector.
