Millet, sorghum and barley malt samples were milled to different particle sizes using a
Thomas-Wiley mill. Equal weights ( - 2.4 kg) of each sample were divided into two parts. Each half ( - 1-2 kg) was separately mixed with 48 litres of tap water (43°C) in aluminium pots to obtain two sets of millet, sorghum and barley mashes. The temperature in one set of the mash was raised to 53”C, then to 63°C in 15 min and then allowed a rest period of 10 min at 63”C, after which the temperature was raised to 100°C. The hot millet,
sorghum and barley mashes were transferred to their other respective mashes held at 43°C with a resultant increase in temperature to 63” + 1°C. The combined mashes were held at 63” + 1°C for 30 min, after which the temperatures were raised to 73” + 1°C held for 25 min at that temperature and then mashed off at 78°C.
