To provide modified coal production equipment capable of easily producing modified coal by performing deactivation of even the raw material coals having various compositions under necessary and sufficient conditions.
Modified coal production equipment comprises: first oxygen adsorption speed measuring units 141-144, 149a, 149b, etc., that sort dried coal 3 dried in a drying device 112, and find the oxygen adsorption speed Vd of the dried coal 3; second oxygen adsorption speed measuring units 145-148, 149a, 149b that sort modified coal 7 deactivated by an deactivation treatment device 130, and find the oxygen adsorption speed Vr of the modified coal 7; and an arithmetic control device 150 that calculates the oxygen adsorption speed ratio N from formula (Vr-Vd)/Vd=N, on the basis of Vd and Vr, and, if N>Ns (a standard value), reads from a map the increased oxygen concentration value Oa in a processing gas 106 corresponding to N, calculates a revised oxygen concentration value Oc on the basis of the current oxygen concentration value Op and Oa, and controls blowers 133, 135 so as to reach Oc.
