How to process potato into starch?

Potato starch processing is an isolation of starch from plant sources. It takes place in starch plants. Starch industry is a part of food processing which is using starch as a starting material for potato starch processing of starch derivatives, hydrolysates, dextrins.

Starch is mainly used as material both in the manufacture of food and non-food products. In food processing a lot of starch is converted to starch hydrolysates. Also it is used to receive puddings, jellies, desserts, caramel and other food products.

step 5- extracting: The mash is discharged into a starch extractor to extract the starch.

step 6- sedimentation: The starch milk is allowed to settle forming two layers i.e. the top free supernatant liquid and the thick starch slurry.

step 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.

step 8- granulating: The “cake” is mechanically reduced in size to produce fine granules of greater surface area.The granulated cake is mechanically dried in a mechanical dryer to reduce its moisture content to about 8 – 10 per cent.

step 9- milling: The dried product is milled to desired particle size (if necessary).

step 10-packaging: The starch is packaged appropriately.
