Abstract

Aiming for the stable operation and the rationalization of factory plant, the color-image processing has been tried to introduce into the online system to measure the crystalline color of L-Lysine in itsrefining process. Because the practical spectrophotometry was used to be employed by manual measurement.<BR>In this paper, the calculation formula of the transmittance by spectrophotometry is theoretically introduced by analysing the relation of Lambert-Beer's lawof luminous transparency with the Kubelka-Munk's function of the luminous dispersion using color image data.<BR>The parameters of the calculation formula were decided by actual measurment, so that the formula withaccuracy value of ± 3% elucidated the possible estimation of transmittance by spectrophotometry.<BR>The system was tested on a commercial plant, and some issues are discussed.
