Potato starch extraction machine extraction of starch from potato

Potatoes are one of the most common and most important sources of food on the earth, and rich health benefits are in it. Today, it’s difficult to imagine a diet without potatoes. Potato tubers contain a large amount of starch. Starch is the main source of energy for edible potatoes, to produce potato starch, you need Potato starch extraction machine.

Following is our Potato starch extraction machine process introduction:

1. Screw/ belt conveyor: used for potatoes transfer, drive the potatoes forward with the spiral rod, continuously working, large capacity, high speed, easy to operate and maintance, the potato starch extraction machine material can be stainless steel or carbon steel as your requests.

2. Rotary drum washer: used for potatoes washing process, filter the sand, weed and other impurities, fully remove the dirt in potato performance and not destroy the potato body. Drum outter equipped with special design, scrape away the deposited soil, guarantee the washer working continuously. At same time, we can add impurity collecting tank in the bottom and sewage diversion tank for you, keep your potato starch production plant clean.

3. Potato rasper: crush potatoes to free starch, Doing Company newest rasper fully destroy the potato cell wall and protein, fine crushing, free the starch entirely from potatoes. Stainless steel structure, advanced technology, long service life.

4. Centrifugal sieve: to washing the potato starch slurry, good performance for slurry seperation, not plug the sieving screen.

5. Desander: further washing the starch slurry, remove the fine particles from potato starch. This Potato starch extraction machine is essential in the semi-automatic potato starch production plant.

6. Airflow dryer: a dedicated drying machine for potato starch extraction machine, fastly dry the potato starch moisture to 12%-14%, get high grade potato starch, its the last step in this semi-automatic potato starch production plant.

Generally, the early maturing potatoes by potato starch extraction machine contain 11% to 14% starch, and 14% to 20% starch is found in the middle late maturing species. The tuber of the high starch varieties can reach more than 25%. The tubers also contain glucose, fructose, and sucrose.The effectiveness of starch removing, depends primarily upon the extent to which the walls of the cells that contain starch granules are cut or ruptured. Because the potato starch granules are larger than other one and have high viscosity, the paste can be prepared with high consistency, so that the quality of potato starch granules in industrial application is much higher than others. Potato starch is mild and non irritating, so it is the best choice for food additives. Deep processing of potato with low investment, low risk and high profit can extend to business opportunities in the industrial chain. Although the investment of the potato starch extraction machine process is small, the profit is huge.
