Computer control of soaking process

The paper deals with application of automatic control via microcomputer technology in leather manufacturing industry. Processing of raw hides comprises a series of particular processes through which raw hide is progressively transformed into the product usable for the production of leather goods which are part of our everyday life. Our contribution is focused only on one problem - the particular process of soaking, in which the input raw material can be irreversibly damaged in case of failing to abide the necessary low concentration gradient. The automatic control system working on the knowledge of mathematical model of physical-chemical processes present in the input raw stock is able to fulfill this condition and thus to secure the quality of the final product
