The invention relates to a coaxial different-speed combined paddle reactor which is used in synchronous saccharifying fermentation of biomass-based ethanol production. The reactor comprises a cylindrical vertical vessel and a stirring device axially installed in the vessel, wherein the comprises a helical ribbon type stirring paddle helically arranged around a stirring shaft from top to bottom, a lower layer stirring paddle installed on the stirring shaft near the lower part of the cylindrical vertical vessel, and a bottom stirring paddle installed at the bottom end of the stirring shaft at the bottom of the cylindrical vertical vessel. According to the invention, a three-blade combination mode is adopted, so that the effects of shearing and circulating materials are achieved; under the combined action of the above two flows, the materials added into the reactor can be quickly mixed, so that the energy consumption distribution in a stirring tank is more uniform, thereby realizing efficient utilization of ener
