Potato starch is starch extracted from potatoes. The cells of the root tubers of the potato plant contain starch grains (leucoplasts). To extract the starch, the potatoes are crushed so that the starch grains can be released from the destroyed cells. The starch is then washed out to separate fiber and other impurities and then be dried in potato starch processing plant.
Then how to make the starch from potato? Here is the detailed introduction of potato starch making process in potato starch processing plant:
1- Sorting and weighing: First, we need to sort wholesome and health potato roots for starch processing. Then the sorted roots need to be weighed.

2- Cleaning & washing: This section in potato starch processing plant is mainly for clean away the debris attached on raw potato.
3- Crushing section: In potato starch processing plant, the peeled roots are grated to produce a smooth mash.
4- Extracting: The crushed potato mesh is sent to a centrifuge sieve to extract the starch.

5- Sedimentation: The starch milk is allowed to settle forming two layers i.e. the top free supernatant liquid and the thick starch slurry.
6- Concentration and refining unit: Then in potato starch processing plant, the starch milk from centrifugal sieve goes into the 16 stages of refining hydro-cyclone, and fresh water comes into the cyclone from the end of system.
7- Dewatering: The supernatant layer of liquid is removed by siphoning off the liquid with rubber hose and the thick slurry obtained is dewatered to reduce its moisture content.

8- Air drying unit of potato starch process plant: After dewatering process in potato starch processing plant, the air dryer will dry the starch to the required moisture of the commercial starch.
9- Milling: The dried product is milled to desired particle size (if necessary).
10- Packaging: The starch is packaged appropriately in potato starch processing plant.
Potato starch contains typical large oval spherical granules ranging in size between 5 and 100 μm, which is a very refined starch, containing minimal protein or fat. Therefore potato is a perfect raw material for starch processing.
