PURPOSE: A method and an apparatus for injecting chemicals into the outermost layer of multilayered fluid only are provided to evenly inject specific chemicals into the outermost layer only as minimizing effect on the other layers of the fluid formed in multilayer. CONSTITUTION: The apparatus includes an ascending and descending unit part comprising a cylinder(54) independently fixed to the lower side of the upper part of container; an immersion unit part comprising an immersion rod which is installed at the lower part of cylinder rod of the cylinder(54), the lower part of which is formed in a tub shape having a predetermined standard value or more of lower cross sectional area, and on the upper part of which chemical projection part(52) is formed in such a horn shape that diameter of the chemical projection part(52) is gradually decreased as it goes from the lower side to the upper side so that the immersion rod raises the outermost layer; a scattering prevention part comprising dust collecting hood(60) which is slidingly installed on the outer circumference between the lower part of the cylinder(54) of the cylinder rod and the upper part of the immersion rod through flowing groove(61) and has an inner shape capable of covering the upper surface of the container containing the multilayered fluid to prevent scattering of the chemicals; a chemical supply part comprising injection liners one end part of which is integrally formed on the side surface of the dust collecting hood(60) in such a way that the injection liners are slantly formed upward in a certain angle, the other end part of which connected to injection lines(8a,8b), and vibration feeders(10a,10b) for supplying chemicals from raw material storage hoppers(9a,9b) to the injection lines(8a,8b) so that the chemicals are evenly sprayed; and a control unit for controlling ascending and descending of the cylinder(54) and opening and closing of the vibration feeders(10a,10b).
