The invention discloses a drying method of wet rice paper poster, which comprises the following steps: putting the wet rice paper poster on a drying bracket and then puting into a drying room for drying, wherein the drying process comprises a preheating step, a constant rate drying step and a temperature reduction drying step; reducing the moisture of the wet rice paper poster to 20%-25%; and drying the wet rice paper poster by a wet rice paper poster dryer. The equipment comprises a stand, heat transfer devices and temperature control devices, wherein the stand comprises vertical supporting poles and beams arranged in the transverse direction of each vertical supporting pole, and the stand is in a frame structure comprising the supporting poles and the beams; the temperature control devices control the heat transfer devices to transfer heat outward; the stand is divided into a plurality of layers of shelf pieces by the beams, and a heat transfer device is arranged between every two layers of the shelf pieces; and a bracket which can be used for placing the wet rice paper poster is arranged between two adjacent heat transfer devices. By adopting the drying method and the drying equipment of the wet rice paper poster, the ink absorption of the dried rice paper is ensured, the energy consumption is greatly reduced in the drying process, the drying efficiency is improved, the labor strength is reduced, and the environment can not be polluted.
