1) About the formation of the double salt: the panboiling method is possible in case of the D. E. is above 90%, the yield is more than 80%. This yield almost coincides with TANEDA'S equation in laboratory. Also the yield increases more than his equation by using longer settling times in a commercial plant.
2) The yield of crystallized glucose on the decomposition changes remarkably by mean of the permissible quantity of sodium chloride that is left in the crystallized glucose. The quantity of water to be used determined respectively for each upper control. If the water used contains 140 percent per glucose, the yield of crystallized glucose is 50 percent. The error variance of observed value in the commercial plant was small than the error variance in laboratory.
