Process Description
(1)Pulp mixing:A certain amount of flour is conveyed from the flour silo to the flour mixer, and suitable warm water is added, after mixing, the pulp needs to be homogenized by the homogenizer.
(2)Three-phase decanter centrifugal separation:The homogenized slurry enters the three-phase decanter, and according to the difference of density, it is separated into coarse A starch, coarse gluten and pentosan.
(3)Gluten extraction:Crude gluten contains a large amount of gluten and B starch, which are separated using a circular sieve. The crude gluten enters the round sieve and is divided into two parts, wet gluten and B starch. In order to separate thoroughly, several gluten sieves are used in series to obtain pure wet gluten in the end.
(4)Extraction of A-starch:The heavy phase material separated from the three-phase decanter is mainly A-starch and fiber and part of crushed gluten, which is separated from A-starch and fiber crushed gluten by centrifugal sieve. The separated fibers will be concentrated and sold as feed after dehydration:A starch is refined and purified by multi-stage cyclone, and then dewatered by scraper centrifuge.
(5)Extraction of B starch:The sieve under sieve of gluten sieve contains B starch and a small amount of fiber, in order to get pure B starch, it needs to be separated in steps. First of all, through the centrifugal sieve to separate the B starch and crushed gluten, separated fibers to be combined with the previous process of A starch separated fibers; and then use the cyclone, divided into A starch and B starch. A starch can be combined with the previous A starch processing, B starch into the two-phase horizontal screw machine for dewatering.
(6) Starch drying:The wet starch after dewatering is sent to starch dryer through feeding winch. After drying and sieving, the finished starch with qualified fineness is buffered by buffer silo and automatically weighed and packed, and then transported to the finished product warehouse.
(7) Drying of gluten: Wet gluten enters into extruder to remove the water. Then the dehydrated wet gluten is fed into the gluten dryer through the feeding winch. After drying and sieving, the finished product with qualified fineness is buffered by buffer bin and then automatically weighed and packed, and then transported to the finished product warehouse.
