Understanding Soybean Crush - CME Group

Soybean Crushing. Nearly 2 billion bushels of soybeans are crushed every year. During the crush process, soybeans are cracked to remove the hull and then rolled into flakes, which are then soaked in a solvent and put through a distilling process to produce pure crude soybean oil. After the oil has been extracted, the soybean flakes are dried ...

Thickening - Resource Book

The increase in flocculation efficiency realised in high rate thickeners may increase in a bulk settling rate 2 to 10 times over that obtained in a conventional thickener, thus reducing the unit area requirements by a similar factor. The corresponding volume may be 4 to 15 times smaller than with conventional thickeners in the same application.
