Potato starch processing plant

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; the starch grains are released from the destroyed cells. The starch is then washed out and dried to powder.

Potato starch contains typical large oval spherical granules ranging in size between 5 and 100 μm. Potato starch is a very refined starch, containing minimal protein or fat.

Then how to make the potato starch from potato? Here is the detailed introduction process of potato starch processing plant:

 1- sorting and  weighing: The roots are sorted to select wholesome roots for processing. The sorted roots are weighed.

 2- Crushing section in potato starch processing plant : The peeled roots are grated to produce a smooth mash.

 3- extracting: The mash is discharged into a starch extractor to extract the starch.

 4- sedimentation: The starch milk is allowed to settle forming two layers i.e. the top free supernatant liquid and the thick starch slurry.

 5- Concentration and refining unit:  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.

 6- 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.

 7-Air drying unit of potato starch process plant: After dewatering process, the air dryer will dry the starch to the required moisture of the commercial starch.

 8- milling: The dried product is milled to desired particle size (if necessary).

 9-packaging: The starch is packaged appropriately.
