Wheat Analysis System Methods – Micro Milling

Grain samples (5-10 g), generally from early generation lines are equilibrated to 13% (soft) or 14% (hard) moisture content. They are milled on the micro mill, where four samples can be milled simultaneously. The micro mill consists of two pairs of corrugated rolls and double sifters with 38 and 135 mesh stainless steel screens. The bran over the 38 mesh screens is evaluated for milling properties by visual examination for the degree of bran clean up. The throughs of the 135 mesh screen is the equivalent to break flour. This is available for small scale predictive tests, such as SDS-sedimentation, Flour Swelling Volume, etc. A schematic of the micro mill is shown in Figure 3. (2),(13)
