Tobacco leaf conditioning method and facility

The invention discloses a tobacco leaf conditioning method and facility. According to the method, water is supplied in a pressurization and pressure stabilization mode, water is conveyed into a heating chamber, water is output through a spray nozzle so that the water can be atomized, and therefore the aim of tobacco leaf conditioning is achieved. Conditioning is conducted on tobacco leaves through a pressurization and pressure stabilization mode and an atomization mode, the utilization efficiency of the water can be greatly improved, the tobacco leaf conditioning time and humidity can be ensured, the conditioning quality of the tobacco leaves is greatly improved, and meanwhile damage caused to heat dissipation devices when conditioning is conducted by evaporating water directly through the heating chamber and the heat dissipation devices in the prior art is eliminated, operation is simple, faults are few and can be easily eliminated, and maintenance is easy.
