Simple enough in theory, the procedures involved in the industrial production of starch escalate in complexity, according to the specific needs of each manufacturer.
Extraction process is the most important process during potato starch production line. The starch grains contained in the potato cells are extracted by crushing the tubers, which releases them from the destroyed cells. The resulted starch is then washed out, dried to powder, and ready to use in either food or various technical applications.
This can affect all process stages during potato starch production line, from the delivery and unloading of the raw product, to the potato cleaning and rasping, to juice separation; then to starch extraction, starch milk refining and dewatering and up to starch drying.
Here is the introduction of potato starch production line:
step 1- sorting: The roots are sorted to select wholesome roots for processing.
step 2- weighing: The sorted roots are weighed.
step 3- peeling: The roots are peeled to remove the peels.
step 4- grating: The peeled roots are grated to produce a smooth mash.
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.
