The invention discloses a starch production system with a horizontal decanter centrifuge for treating underflow materials, comprising a clarifying centrifuge, a condensed cyclone, a scraper centrifuge overflow liquid tank, a main separator feeding tank, a main separator, a starch refined cyclone, a refined starch milk tank and a starch milk refined system top flow tank; a clarifying centrifuge inlet is connected with a scraper centrifuge filtrate outlet pipeline; a clarifying centrifuge underflow outlet is connected with a scraper centrifuge overflow liquid tank pipeline; the scraper centrifuge overflow liquid tank is connected with the scraper centrifuge filtrate outlet pipeline; a scraper centrifuge overflow liquid tank outlet is connected with a feeding hole pipeline of the horizontal decanter centrifuge; materials in the scraper centrifuge overflow liquid tank are separated by the horizontal decanter centrifuge according to the weight; top flow of the horizontal decanter centrifuge reflows to the starch milk refined system top flow tank; and underflow of the horizontal decanter centrifuge enters the refined starch milk tank. By adopting the horizontal decanter centrifuge to treat overflow liquid and filtrate, the invention reduces the feeding amount and the load of the main separator, improves the production load and the protein yield and reduces the production consumption.
Description
technical field [0001] The invention relates to a starch production device system, and in particular discloses a starch production system with a decanter centrifuge for processing underflow materials, which is suitable for improving the quality of starch and reducing the protein content in finished starch and improving the yield of protein feed Wet processing belongs to the technical field of grain processing. Background technique [0002] As we all know, the corn starch production wet processing fine slurry is separated by the pre-concentration separator and the main separator, and the underflow enters the starch milk refining system, enters the scraper centrifuge for dehydration, and then enters the airflow drying system, and obtains the finished starch after airflow drying. During the working process of the scraper centrifuge, a part of the overflow of the scraper centrifuge and a part of the filtrate of the scraper are produced. The scraper centrifuge overflow and scrap...
