GEA has introduced Varipond C, a new technical solution for decanter centrifuges that enables simple, fast and precise adjustment of the separation zone and pond depth.
Varipond C ensures consistent separation results and a high product yield and quality, for example in beverage, food and edible oil production, as well as in refineries. It also helps to reduce energy consumption by around 30% compared to conventional centripetal pumps. The system is available for all GEA decanters ranging from CF 3000 to CF 8000 and is suitable for both two-phase and three-phase processes, regardless of decanter size, where users need to respond to varying feed conditions, flow rates or different starting materials.
As factors such as weather conditions or processing times affect the water, oil and solids content, to ensure consistent separation results, the separation zone in the decanter must be continuously adjusted. With GEA Varipond C, this can be done manually or through automated adjustment during operation – quickly and without interrupting production. This means that pond depth and separation quality can be optimized at any time without compromising on the yield and quality of the solid and liquid phases.
With Varipond C, the pond depth and separation zone can be precisely adjusted either manually with a handwheel or automatically with a servomotor to optimally adapt the separation process to different operating conditions. At the same time, the system reduces energy consumption by about 30% compared to conventional centripetal pumps due to lower friction effects. The food-grade design allows for full CIP cleaning of the Varipond chamber and the use of food-grade lubricants, seals and materials.
Varipond C can be combined with a hydrohermetic sealing to prevent oxygen intake. This reduces product oxidation and improves quality, which is particularly beneficial in the beverage industry.
Combined with the pre-installed IoT gateway and connection to GEA Cloud, Varipond C enables comprehensive process optimisation. GEA Cloud Services collect process and machine data and provide dashboards for real-time and historical data analysis. Based on this information, the Varipond C settings can be optimised for different feed conditions. Users can also store recipes and operating guidelines to make optimal settings reproducible.
GEA Varipond C can be used in a wide range of applications where a centripetal pump is required. These include processes in the food and beverage industry, in edible oil production and in refineries. Typical applications are:
- 2-phase / 3-phase wheat starch
- 2-phase / 3-phase animal fats and proteins
- 2-phase olive oil
- Vegetable-based drinks
- Fruit juice
- Oily water, sludge and refinery oil water
The system is already successfully in use in the processing of starch, animal fats and proteins.
