Dry processing methods •Cracking or dry rolling: It is the disintegration of kernels into particles with the application of pressure by moving rollers. It is done by a combination of breaking and crushing of the grains. The physical properties of dry rolled or cracked grain would be very similar to that of grains coarsely ground in a hammer
