Potato starch is starch extracted from potatoes. The cells of the root tubers of the potato plant contain starch grains . To extract the starch, the potatoes are crushed; the starch grains are released from the destroyed cells. The starch is then washed out and dried to powder.
Starch derivatives are used in many recipes, for example in noodles, wine gums, cocktail nuts, potato chips, hot dog sausages, bakery cream and instant soups and sauces, in gluten-free recipes and in Asian cuisine.

Then the crude potato starch milk will be pump to the refining section ,afrer de-sanding and purifying by hydro cyclone group , the purified potato starch is produced . Then the purified potato starch milk will be sent to dehydration setion , dewatering by vacuum filter and drying by air flash dryer .
