Abstract: A bucket type elevator having a head pulley and a boot pulley with a belt entrained about both pulleys is hydraulically driven. The drive mechanism comprises a hydraulic motor mounted in the boot pulley. It is connected, via flexible hydraulic lines, to an electric motor driven pump and fluid source located near ground level outside the boot housing, easily accessible for maintenance and replacement but far enough away from the elevator to avoid risks of explosion from the electrical power source. The elevator also includes a tensioning system for maintaining adequate and uniform tension across the width of the belt and for preventing slippage and miscentering of the belt on the boot pulley.

Abstract: A system for treating oilseeds prior to solvent extraction in which the oilseeds are treated in a microwave dryer to raise their temperature to 140.degree. F., passed hot through two-high rolls to crack the hulls and beans, the hulls are removed in an air sorter while at 140.degree. F., and while still heated, the beans are sent to a flaking roll. The stream from the process to the solvent extractor has less than 5% fines.
