The invention provides a furan resin preparation system and a furan resin preparation method. The system comprises a workbench, a power mechanism, a material receiving mechanism, a powder spreading mechanism, a stirring mechanism and a feeding mechanism, wherein a material receiving disc is arranged below the workbench, the power mechanism comprises a driving assembly and a conveying assembly, thematerial receiving mechanism comprises a material receiving assembly and a position limiting assembly, a powder spreading device comprises a powder spreading assembly and a control assembly, the stirring mechanism comprises a stirring assembly and a rotating assembly, and the feeding mechanism is installed on the workbench. According to the invention, the conveying assembly rotates, the powderedraw material enters the powder barrel, the granular raw material enters the material storage barrel, the control assembly drives the powder spreading barrel to rotate so as to diffuse outwards the powdered raw material into the gaps of the granular raw material, and then the stirring assembly rotates forwards and backwards to uniformly mix the materials, so that the technical problem that different fluidities caused by different particle sizes during material mixing can cause non-uniform material mixing can be solved.
