The proportion of starch and water is such that 4 inches of starch is overlaid with about 6 feet of water. The crude starch obtained in this tank is then thrown into another tank of a similar size which is fitted with a revolving stirrer; water is added in large quantities at the same time and the starch is beaten into a cream and again allowed to settle. The interior view of such a tank can be seen in Fig. 26. This process washes the starch and removes the larger portion of Fio.
