TECHNICAL PROFILE

Soybean dehulling process
O
ilseed production has increased considerably in recent decades, mainly because of higher consumption of edible oils, especially in emerging countries, but also thanks to biofuel production in industrialized nations. Five oilseeds are mainly used for oil production: rapeseed, cotton, peanuts, sunﬂowers and soybeans. Soybeans are by far number one as they account for more than 50% of global oilseed production. In 2010, 258 million tonnes of soybeans were harvested. The importance of soybeans has grown substantially in the last 10 years, mainly in the three dominating markets: the U.S., Brazil and Argentina. Although soybeans have medium to low oil content in comparison with, for example, rapeseed or sunﬂower, they are still very popular because of their high protein content and because they contain all eight amino acids that are essential for human health. When it comes to soybean vegetable oil and meal production — 85% of the world’s soybean crop is used for these

Front-end dehulling and hot dehulling are usually the methods of choice for oilseed crush managers
purposes — oil crush managers are searching for ways to increase the efﬁciency of the crush process in order to gain a higher margin. The crush margin is the difference in price between the raw material and the products extracted after crushing, and serves to cover operational costs and to gain higher proﬁts. The products produced after crush Table 1 and extraction are crude oil, hulls and extraction meal. While hulls are mainly used for heat generation, the extraction meal from oilseeds is a valuable, protein-rich animal feed source. The quality and, consequently, the price of the extraction meal can be increased by choosing the best soybean dehulling technique for the preparation plant
