FIELD: process engineering.
SUBSTANCE: invention relates to devices intended for mixing single-component fluid and mixing two and more fluid components. Mass transfer device comprises tube housing 1, one or several feed branch pipes 2, mix discharge branch pipes 3, mixer made up of one or several coiled rectangular-section strips 4 with front and rear surfaces 5 and 6 that has central and extreme parts 7 and 8 running along strip length Cutouts 9 are arranged perpendicular along at least one edge of strip, starting from outer edge 10 to extend to through holes 11. Centers of said holes are located at distance not exceeding ? of housing ID to form rectangular lobes with their lengthwise edges turned opposite central twisted section 7 of said strip.
EFFECT: higher mixing quality, simple design.
