Summary
Quantitative data have been presented for the effect of “effective extraction size” on the rate of extraction of oil from soybeans, peanuts, cottonseed, corn germ grits, and flaxseed. Both flakes and grits have been studied. The results are best correlated by a straight-line plot on log-log paper of “time to 1% residual” and effective extraction size. The slope of the line is a measure of the change in extraction rate with extraction size. The slope was found to be different for the different oil seeds and to be larger for seeds prepared as grits than for the same seed prepared as flakes.
