dcterms:description
Curing with concentrated brine solution (sodium chloride) is a common method for raw hide preservation. Sodium and chloride ions diffuse towards the raw hide inner volume, which initiates the counter-current transport of water from the raw hide inner volume. The result of the two-component counter-current diffusion is increasing salt content and decreasing water content in the raw hide inner volume. For optimization of the curing process it is necessary to determine the time dependence of the brine concentration from the hide surface towards its center, it means the non-stationary concentration field in the inner volume of the hide. For this reason we have proposed a mathematical-physical model for NaCl diffusion in the hide. We have also carried out the numerical solution of the model; the solution comprises the concentration fields of sodium chloride and water during the curing process. The respective effective diffusion coefficients and their dependence on brine concentration have been determined e Curing with concentrated brine solution (sodium chloride) is a common method for raw hide preservation.
