A Simple and Rapid Method to Measure Wheat Hardness by Grinding Time and Speed Reduction in a Micro Hammer-Cutter Mill.

Wheat hardness can be simply and quickly measured by determining the time required to collect 17 ml of ground wheat from a 20-g sample in a commercial micro hammer-cutter mill at 3,600 rpm. Hard and soft wheats differ in grinding time and in the amount that the machine's speed is reduced. No correction was necessary for grinding time and speed reduction at moisture levels of 9.3-12.7%.
