FIELD: leather industry.
SUBSTANCE: hides are loaded into apparatus drum, into which working solution is then added and drum is started to rotate displacing hides in working solution, after which working solution is recycled and hides unloaded. Recirculation of working solution is effected within combined circuit including two or more apparatuses according to process flowsheet, wherein working solution is successively in-line routed to a ready-to-use drum directly from another drum, in which treatment cycle is ended, through filtering-pressure blind area common for all the combined circuit. Treatment is effected, depending on the number of drum apparatuses in combined circuit, with simultaneously in-parallel performing two or more operations of the same process. Invention is also related to apparatus for carrying out the claimed method.
EFFECT: increased productivity and economical efficiency of process.
