In the cutting / shredding processes applied when the potatoes are sliced or divided into particles of different sizes; The white starch on the potato surface becomes free and mixes with the water. In addition, it was determined that the clean water used for washing the cut potatoes contains starch. The production waters formed in this type of factory are sent to the treatment plants to be treated. BOD and COD values of starch-containing waters are quite high and their treatment/chemical consumption will be quite high. In addition, the following benefits can be achieved by using decanter centrifuges.
1. Evaluation of starch obtained after recovery
2. Reducing the load and operating costs of the wastewater treatment plant
3. The clean water coming out of the decanter can be used again as potato cutting/washing water and reducing the need for clean water.
By using HAUS Decanter Centrifuges, 2500-3000 kg of starch is recovered by working 10-12 hours a day. It has many application areas and the high quality starch obtained is dried and brought into the economy.
Process water from potato cutting machines is clarified by means of a rotary drum strainer. For optional cleaning; By using cyclone filters or fiber filters, it captures sediments over 100 microns. The product fed to the decanter centrifuge; Starch is dewatered to contain 50% dry matter. Then the dried and packaged product can be used in industrial and food applications.
