The invention discloses a forced heat recovery type energy-saving tobacco curing barn which comprises a tobacco loading chamber (1) and a heating chamber (2), wherein the tobacco loading chamber (1) is separated from a heating chamber (2) through a heat insulation wall (13); humidity exhaust outlets (3) communicated with the tobacco loading chamber (1) are formed in two vertex angle positions of the heat insulation wall (13); an air inlet (4) is formed in the heating chamber (2); total heat exchangers (6) are respectively arranged on the humidity exhaust outlets (3) through heat insulating tubes (5) in a connecting manner; a fresh air outlet (61) of each total heat exchanger (6) faces the air inlet (4); fans (7) are respectively arranged on the fresh air outlets (61) and humidity exhaust gas outlets (62) of the total heat exchangers (6). The total heat exchangers are used for performing heat exchange on fresh air and hot humid air exhausted from the humidity exhaust outlets, and preheated fresh air blows towards the air inlet from the fresh air outlets, so that heat recovery of humidity exhaust gases is realized, the loss of heat in the humidity exhaust process is avoided, and electric energy is saved.
