tent of individual wheat kernels among the tempered wheat following the moisture addition, by allowingtime for moisture transference from kernel to kernel to achieve uniformity. Complete penetration of moisture inside the wheat kernel. The optimum milling moisture and tempering time are both required to obtain opti- mum milling performance relative to the following objectives: Toughen up the bran so that it will resist powdering in the milling process Enhance easier separation of the bran from the endosperm 2 Sarkar Mellow the endosperm sufciently that it can be rather easily ground into our Allow the ground material to be sifted easily and efciently When analyzing these objectives, it is clear that drier wheat when ground will sift easily, as well as that the bran separation from endosperm in drier wheat can be accom- plished easily, although the bran will have tendency to chip or shred. On the other hand, moist wheat will have tougher bran that will resist powdering in the grinding process andthe endosperm will be mellower. Therefore, delicate balance between the two, whichmay be further inuenced by several other factors, would provide the optimum conditions.Although all the foregoing objectives are inuenced by the milling moisture level, thethird point relating to the mellowness will also be heavily inuenced by tempering time,which must be sufcient to allow complete penetration of the desired moisture level inside the kernel. Optimum milling moisture and tempering time will be determined by Kernel texture (hardness) Ambient temperature and humidityEnd use quality requirementsRequired our moisture Milling performance for production would be measured by the following functions: Throughput (milling capacity) Flour extractionMilling moisture Milling performance relative to quality would be measured by the following attri- butes: Flour moisture Flour granulationPhysical starch damage level in the ourFlour ash content or color grade value as measure of our renement
