The invention belongs to the technical field of preservation devices, and particularly relates to a fermented flour product efficient preservation device which comprises a preservation box, a cover plate is detachably connected to the upper side of the preservation box, a buckle plate is hinged to the side wall of the cover plate, an exhaust assembly is fixedly installed on the upper side of the preservation box, and a positioning device is arranged on the side of the preservation box. An auxiliary sealing assembly is fixedly connected to the outer wall of the preservation box and comprises a fixing block, and an air bin is formed in the fixing block. According to the efficient fresh-keeping device for the fermented flour products, an auxiliary sealing assembly is used, after a buckle plate rotates and buckles a fixing block, the buckle plate can extrude a piston block, the piston block compresses a reset spring to extrude gas in a gas bin into a through pipe, then the gas is supplemented into an elastic seal
