| Résumé : |
Within the optimization of the white hide deliming operation, both plain washing with pure water and chemical processing are concerned. Generally, white hide contains both non-bonded and variously strongly bonded lime. The processing costs of the deliming of non-bonded lime are relatively low, but with decreasing concentration of lime in hide they go up, because the strength of the lime bond increases. In a certain stage of the deliming process, the processing costs begin to increase extremely and in this point it is suitable to interrupt the washing with pure water and replace it with a deliming agent. Our paper, with the use of a mathematical-physical process model, gives the answer to when the interruption should be done. Experimental determinations of sorption isotherm, as well as the effective diffusion coefficients are presented. The above mentioned parameters, economical and technological serve as input data for a computer program. |
