Abstract: In order to solve the problems of high energy consumption, cost and pollution in biomass energy curing barn, a new built-in type of integrated biomass intensive curing barn was designed. The device performance, economic characteristics, appearance and sensory quality of cured-leaves, gas emission and integrative benefit in three types of bulk curing barn (coal-fired, external biomass, built-in biomass) were compared. The results showed that the temperature stability performance of the new built-in biomass curing barn was better than that of the coal-fired bulk barn and was equivalent to that of the external biomass curing barn in cutter leaves. The average labor cost of cutter and upper leaves decreased with the amplitudes of 88.98 and 10.80 percentage points, respectively; The average price of the same part of tobacco leaves increased by 1.89 and 0.26 yuan/kg, respectively; The oil content of cutter and upper tobacco leaves were all increased slightly and the impurity gas were all decreased slightly; The average net income increased by 2.63 and 0.46 yuan per kilogram of tobacco leaves, respectively; The total emissions contents of four harmful gases in the stack gas of the new built-in biomass curing barn under cutter leaves were reduced by 9235.70 and 1 524.73 mg/m³, respectively. Therefore, the new built-in biomass barn has the best curing effect and is worth popularizing.
