The present invention relates to a functional sunscreen manufacturing apparatus using a photoperiod, in particular, a sunscreen is manufactured by mixing antimicrobial and detoxifying actinomycetes and photoperiodic actives to eliminate the odor, and furthermore, it is boiled using a biotite radiating far-And a high-quality functional food is produced by radiating far-infrared rays.A steam generator (20) installed on the steam generator, a cover (30) installed on the steam generator, and a biotite feeder installed on the side of the steam generator to supply biotite (60), and a biotite-filling automatic adjusting means installed at one end of the biotite feeder to automatically control the biotite input, wherein the steam feeder (20) forms a space part A plurality of holes 21 are formed in the bottom surface so that the steam supplied from the steam generating unit 10 is easily supplied to the steam generator 1 through the steam feeder 20 The steam generating unit 10 includes heating means 11 installed to penetrate a side surface of a container body and configured to radiate thermal energy by being supplied with electricity from outside, A water level measuring means (12) installed at one side of the container body to check the level of water present in the container body, and to output an alarm signal to the outside when the water level falls below a reference level And a far infrared ray providing means (13) installed on the bottom surface of the container body and configured to provide far infrared rays at the top of the hull by diverging the far infrared rays upwardly and made of biotite The biotite feeder 60 includes a first biotite filler reservoir 61 installed at a side of the steam generator and vertically installed to supply biotite through the internal space of the first biotite filler vessel 60, And a second biotite reservoir (62) installed at an oblique angle to supply biotite supplied through the first biotite reservoir to the bottom of the steam genera
