The present invention provides a dried gel sheet manufacturing apparatus and method, and a gel sheet. The dried gel sheet manufacturing apparatus includes an applying unit 2 which includes gravure rolls 22a and 22b to apply a hydrogel composition of a reserving tank 24 on a supporting member M which is conveyed together with a lower film Fa to form a sheet shaped hydrogel H, a cooling drying unit 4 which cools the sheet shaped hydrogel H using a cooling plate 44 to be solidified while being transported; and a heating drying unit 6 which dries and irons the solidified sheet shaped hydrogel by a combination of a heater roll group 64 and a nozzle unit 66 or the nozzle unit 66, a dry conveyer 68, a godet roller 70 or a nozzle unit 66, a dry conveyer 68, a heater roll group 64, or a nozzle unit 66 and a godet roller 70 to obtain a gel sheet G2. Further, a dried gel sheet manufacturing method through the apparatus includes an applying step of forming a sheet shaped hydrogel H by a lower film Fa and protecting the sheet shaped hydrogel by adhering the upper film Fb on a top surface; a cooling drying step of passing the sheet shaped hydrogel H at a low temperature atmosphere to be solidified, and a heating drying step of receiving and separating the upper and lower films Fb and Fa from the sheet shaped hydrogel H which is solidified by the cooling and heating and drying the front and rear surfaces by ironing the sheet shaped hydrogel to collect the gel sheet S2. Through the manufacturing method, a gel sheet G2 which is formed to be a film so that density of the front and rear surfaces is higher than a center portion and a beauty pack obtained by pressing the gel sheet S2 by the mask member MP are suggested.
