Summary
The temperature has a considerable effect on the rate of extraction of crude oils from vegetable oil seeds with solvents. Quantitative data have been presented relating extraction rate and temperature for soybeans, cottonseed, and flaxseed extracted with several solvents. These data were obtained by the Percolation Method, modified where necessary.
Since no satisfactory theoretical basis for correlation could be established, the results were correlated empirically. For all practical purposes the time in minutes required to reduce the oil seed to 1.0% residual oil content on a dry basis varied inversely with the square of the extraction temperature in degrees Fahrenheit.
