The main processes of potato production line are following:
1 Potatoes from local farmers are transported to the factory by trucks,
2 The potatoes are washed and rasped into fine particles in a rotating grater,
3 Fruit juice and solid matter are separated into two streams in a rotating decanter, 4 Fresh water is added to the stream of solid matter and pulp is separated from the starch by centrifugation
5 Starch is refined in hydro cyclones and vacuum filters,
6 The concentrated slurry is dried in a warm air stream until a final water content of 20%
7 The starch is stored and packed for final distribution to the market and sold as potato flour or potato starch.
The potato starch is then extracted followed by washing. The washing line consists of 3-phase nozzle separators in three stages working on the counter-current principle, fresh water only having to be supplied to the last stage.
