FIELD: leather driers. SUBSTANCE: device for evacuation of industrial leather driers includes not closed system which has steam pipe lines for each rack located in succession, first condenser fitted on each pipe line, first condensate separator, main vacuum pump designed for gradual reduction of absolute pressure in system from first upper magnitude. system is provided with additional suction device located before main vacuum pump and designed for operation in series with this pump after attaining first magnitude of absolute pressure in order to additionally reduce pressure in system to second lower magnitude. Upper magnitude of absolute pressure ranges from 40 to 100 mb and second lower magnitude of absolute pressure ranges from 15 to 1 mb. Used as evacuation device is hinge-capacity blower at low pressure head. EFFECT: evacuation at lower vaporization temperature and temperature of racks. 13 cl, 1 dwg
