. The production and utilization of corn oil in the United States . ORN OIL. agglutinated into small round balls, is passed through thrashers,which break up the balls, and then passed again through the driersuntil the moisture has been sufficiently reduced. After all the germ material has been separated in the mannerdescribed and washed free from starch it is run through moistureexpellers to take out some of the excess water. The machines usedare the same as those employed for expelling moisture from the feedmaterial. Two types are in use. One consists of two verticalplates operated separately and so attached to separate shafts thatthe space between the plates at the bottom is much less than at thetop. The wet material is caught in this constriction and the excesswater squeezed out.(Fig. 6.) The othertype is constructedon lines similar toan oil expeller. Itconsists essentiallyof a worm revolvingin a steel barrelthrough which thematerial pressure is ad-justed by means ofa steel cone at theforward end of themachine.

After the excessmoisture has been removed, the germs are conveyed to the driers,which reduce the moisture to 5 per cent or less. These driers are alsoused for drying feed. In hominy mills the germs are also dried, but apparently not tosuch a degree. For this purpose there is in use one main type ofdrier which has been revised from time to time. (Fig. 8.) Theoldest form consists of a long cylinder or drum about 5 feet in diam-eter and 28 feet long. On the inside of this cylinder, around thecircumference, are parallel steam pipes 4 inches in diameter, and thewhole apparatus slowly revolves. The steam enters through anopening in the central shaft, while the material to be dried
