The invention relates to a continuous production apparatus and production method of a high polymerization degree semi-biomass-based furan polyamide resin. The used apparatus successively comprises a pre-polymerization system, a polymerization system and a heat exchange system. A continuous production process of the semi-biomass-based furan polyamide resin comprises the following steps: mixing a furoyl chloride compound and an amine compound; performing a pre-polymerization reaction to obtain a pre-polymerization product; then performing a polymerization reaction to obtain a polymerization product; and finally performing post-treatment on the polymerization product. The continuous production of the semi-biomass-based furan polyamide resin can be realized by adopting the apparatus, heat transfer is uniform, the mass transfer effect is good, and the temperature adjustment effect is good. The semi-biomass-based furan polyamide prepared by the method has high molecular weight, relatively low polydispersity, and ea
