Modelling and control of raw hide desalting process

Abstract

The contribution deals with optimizing of desalting process during soaking and application of automatic control via microcomputer technology in leather manufacturing industry on the base mathematics deterministic diffusion model describing desalting process. Processing of raw hides comprises a series of particular processes through which raw hide is progressively transformed into the leather. Using a combination of mathematical modelling and laboratory testing by automatic control system we search an optimal procedure for desalting with regard to ecological and economic aspects. In this paper we describe testing of desalting in the flow systems with flow rate automatic control. The obtained results confirm the elimination of concentration shocks which cause the collapse of the surface layer texture of cured hide.
