In order to make a logical comparison of the oils obtained by both the expeller and the benzol extraction processes it was necessary that both types of oil should be obtained from the same lot of germs. The mate- Z?£(3/i~/?Af£'/? rial used in the ex- periments was ob- tained from typical hominy and glucose plants, the former producing dry- process germs and the latter wet- process germs. A day was spent in one plant of each type, and the material was collected, a little at a time, during a period of about seven hours. In this way approxi - mately 150 pounds each of the germs and oil cake and about 5 gallons of expeller oil were ob- tained. This method of collecting the ma- terial gives reason- able assurance that the three types of oil, namely, the ex- peller oil and the oils extracted with benzol from the germs and from the cake, are derived from approximately the same germ stock. Figure 1 shows graphically the plan according to which the material was collected. BENZOL EXTRACTION OF CORN GERMS AND OIL CAKE. The germs and oil cake were ground to a suitable degree of fine- ness, and 50 pounds at a time were extracted in a large, heavy, gal-. /P££/A/££ £££//>/££> tf£F/A£0 £/Yy<?/Crf/rC//£/y/C/?L C0A'&T/?A/71S COLOrf-a/PO/?- T/9^T£ Fig. 1.—Diagram showing the method of collecting corn ma- terial for the extraction of oil.
