Dry peeling corn and
corn oil extraction processing form is varied, process route length is differ, the basic process is as follows: raw grain, cleaning, water, food, peeled (suction), crushing, grading, germ slag Main working procedure in the whole process is water embellish, peeling, crushing and separation of four link, with crushing and separation is the most important. Add water and embellish food: the corn water is in order to better stripped corn husk. For low moisture content of corn with just the right amount of water before degerming, advantage of the characteristics of germ will swell to improve elasticity and toughness, the embryo and endosperm in combination with relaxation, more conducive to degerming. Water added size according to the high and low and climate conditions of the natural water content of raw grain. Low raw grain moisture content, low temperature, can add more water.
Water added in corn peeling process can be controlled in 16-18%. Embellish food for 5 to 10 minutes. For raw grain and water, simply run in the skin or into the body, not allowed to enter the endosperm, or high moisture, not only difficult for milling, but also do harm to the safe keeping.
Skinning: corn peeling is an important process to improve the quality of products.It's better to use friction to skinning. In order to avoid the damage in the process of peeling endosperm, as much as possible the skin less powder. Much stripping quantity is unfavorable, generally around 50%, with crushing equipment and a few ink roller mill, the entire process peeling rate is 80-90%.
