In oil milling plant, soybean peeling/hulling machine can effectively increase the oil extraction capacity and reduce residual oil in soybean meal. In general, the husk content of soybean is 5%~8%, while the oil content of the peel is less than 1%. Leaving the soy hulls in oilseed processing can waste spaces of oil press machine. In order to improve the oil production and reduce energy consumption of oil milling plant, it is necessary to remove the hulls before pressing and extracting with soybean peeling machine or soybean hulling section.

Soybean Peeling Section (Hulling System)
By convention, advanced twice de-hulling technology is adopted for oil milling process. After being cracked first time by the teeth-roller crackers, the cracked soybean passes through the first course air classifiers. The cracked soybean hull will be sucked out from soybean kernel and collected by cyclone. Then the soybean is cracked again by the teeth-roller crackers, and air classified again by second course air classifiers. Then the mixture of soybean hull and small-size kernel is screened by flat rotary sieve. Soybean hull on the screen will be sent to be milled by Mill, and then stored temporarily in Hull Bin. Twice de-hulling process can remove soybean hull over 85%, it can assure the final by-product, Soya Meal, contains high protein. According different customers’ requests in Soya Meal, e.g. some customers want Soya Meal with low protein content; add proper quantity of soybean hull into the meal to produce meal meeting various requirements of protein content of meal. The separated soybean kernel under the screen is sent to Flake Roller to be flaked.
Types of Soya Peeling/Hulling Line
Soya peeling technique generally can be divided into cold dehulling, warm dehulling and hot dehulling.
