Studies of potato starch production process (2) - 4-Elements method and correlation analysis

We have discussed the definition and the calculation for the four characteristic components of potato in the previous paper [1]. In this paper, these components of the four characteristic parameters are calculated by using the data of chemical analysis of raw materials and the measured values of decanter waste juice in a laboratory of the starch process plant in 1997. The calculated results approximately agree with the data of the four components derived from the production process equation shown in [1]. Therefore, the method for solving the process structure equation, which is named "four elements method", is applied to the process analysis of the potato starch plant. Furthermore, the multi corruption analytical method is introduced to examine a relation between de-juiced potato-mass (BB) and rasped potato. The de-juiced potato is a kind of slurry which is obtained by separating decanter waste juice from wet rasped potato and includes unrasped potato, starchiness, the wet pulp milk and the residual potato-juice. The percentage of BE to the rasped potato is obtained as 42.99% by solving the multiple factor for the results of separation analysis and centrifugal analysis of the decanter. Finally, it is confirmed that the data obtained by the proposed analytical method has small differences comparing with the index number of production control for the potato plant, 45%.
