The potatoes will be stored in the day storage after weighed. From the day storage the potatoes will be transported by water stream through a trough into the gravity de-stoner as well as washing without damage and further into the drum washer.

The washed potatoes will be taken up by an inclined belt conveyor, which transports them into the rasper. The special designed stainless steel rasper is easy to operate. The most effective but simple clamping system guarantees an optimal position of the rasper blades and the clamping working.

After rasping the obtained potato slurry will be pumped into a de-sanding cyclone unit. The sands will be discharged periodically automatically.

From the de-sanding unit the potato slurry enters into the extraction unit consisting of 3 conical rotary sieves with integrated fibre and starch slurry pumps.

The washed-out starch slurry from the extraction unit will be pumped into the sixteen stage concentration and starch milk washing unit.

The concentrated starch milk from the last stage will enter the washing unit. The final starch milk concentration is automatically controlled.

The final starch milk is pumped to the filter trough of the rotary vacuum filter. The starch milk is diluted with water. The starch is sucked against the surface of the rotating drum and is scraped of by a fixed scraper device.

The dewatered starch cake is transported to the inlet of the flash dryer where the starch is further dewatered into a commercial starch. The starch is extracted by the semi-automatic bagging installation, where the starch is bagged into 25kg bags.

Sodium bisulphite will be added to the process constantly at a 38% solution.
