1. A biomass solid fuel manufacturing device comprising:
a rotary kiln that carbonizes a biomass molded body molded from raw material biomass,
wherein the rotary kiln includes a kiln body, a supply pipe having a tubular shape configured to supply the biomass molded body to an upstream end portion of the kiln body, and an inert gas supply including a first nozzle and a second nozzle,
wherein the first nozzle is configured to introduce inert gas to an upstream end portion inside the kiln body and configured to discharge the inert gas in a radial direction inside the kiln body, and
wherein the second nozzle is configured to introduce the inert gas to the supply pipe and configured to discharge the inert gas in a radial direction inside the supply pipe.
