Abstract: A grain scratcher-moisturizer apparatus has an outlet connected by a screw conveyor to the infeed of a stream flaker assembly to provide substantial savings in the cost of treating feed grain. The scratcher-moisturizer has two driven parallel horizontal cylindrical rolls having closely spaced spiral grooves in their surfaces for receiving the base of a saw blade so that the teeth of the blade extend outwardly and are canted in the direction of rotation of the roll. Individual pivotal metal deflectors are mounted adjacent a respective cylindrical roll and grain is fed onto the driven rolls which hurl it against the deflector which deflect the grain back toward the roll.
