Abstract: A biomass solid fuel manufacturing device (100) includes: a rotary kiln (2) that carbonizes a biomass molded body molded from raw material biomass. The rotary kiln (2) includes a kiln body (20), a raw material supply unit (30) that supplies the biomass molded body to an upstream end portion of the kiln body (20), and an inert gas supply unit (50) that supplies inert gas to an upstream end portion inside the kiln body (20).

Abstract: A biomass solid fuel manufacturing method, including: a heating step of carbonizing a biomass molded body formed by molding raw material biomass, in an external heating type rotary kiln, in which the rotary kiln includes a non-heating zone that is provided on an upstream side of a kiln body and is not provided with a heating unit on an outer circumference, the non-heating zone includes a spiral blade on an inner circumferential surface, and in the heating step, the biomass molded body is introduced to the non-heating zone of the kiln body.
