Five Different Roll Roughness's 1. Flaker Rolls (130-150) Roughness is an important characteristic of flaker rolls during the seed oil production process. When seed oil is processed through a set of rolls, they are flattened and sheared to an ideally thick flake. If the flake is too thick, all the oil cannot be removed from the bean.

Laser and electron beam-based texturing technologies produce repeating patterns and micro-features in the roll surface that prevent the sheet being acceptable for use in exposed automotive applications. Roll processing times are dramatically slower than EDT. Furthermore, consumption of inert gas during the texturing process is wasteful and costly.
