Increased capacity and better performance from Alfa Laval's three-phase starch decanter
When Cargill decided to increase the capacity of their wheat starch factory in Poland, the company turned to Alfa Laval for a cost-effective and reliable solution, which is exactly what the Alfa Laval STNX944 decanter gave them.DATUM 2017-07-13
The most crucial step in the wheat starch production process is the splitting of the wheat dough into the various component streams for downstream processing.
This has traditionally been done in 2-phase decanters or in hydro- cyclones. However, the 3-phase decanter is increasingly becoming the preferred solution within the industry.
When Cargill decided to increase the capacity of their wheat starch factory in Poland, the company turned to Alfa Laval. What they needed was a cost-effective and reliable solution - which is exactly what they got, with the new Alfa Laval STNX944 decanter.
The STNX two and three-phase decanter centrifuges are optimized for starch production. STNX decanters offer gentle product handling, high performance and automatic adjustment to variations in operating conditions. Using decanter centrifuges instead of traditional rotary vacuum filters for dewatering frees up production space, makes it possible to increase capacity on available floor space and reduces energy consumption in the drying stage.
Decanters operate more reliably and efficiently than other technologies and require only minor attention from operators. The unique control system improves performance and makes operation easy, safe and cost-efficient.
- High capacity - the STNX944 can handle up to 10 tons of wheat flour per hour with a high-quality, reliable 3-phase split.
- High-quality "A" starch and gluten, with a high starch yield.
- Simple design, making for ease of operation and lower maintenance costs.
- Reliable, proven technology assures the best possible equipment availability.
- The STNX944 does not require a paring disc, unlike other comparable machines. This translates into a significantly lower installed power and lower heat input.
- Splitting of the different phases by density allows regulation that is independent of flow.
- In contrast to our competitors' machines (where either a fixed nozzle or an adjustable paring device is used for discharge of one of the phases), no additional dilution water is required by the STNX944.
When Alfa Laval presented us with the data on their new decanter, we were very interested in the simplicity of its design and the high capacity that Alfa Laval claimed for the machine.
