Energy-saving control method and device for cut-tobacco drier

The invention provides an energy-saving control method and device for a cut tobacco dryer, and the method comprises the following steps: S1, obtaining a current incoming material signal of a feeding machine, determining that the parameters of the cut tobacco dryer meet a preset condition, and preheating heating and humidifying equipment; S2, continuously acquiring flow signals of the electronic scale; S3, when the flow signal of the electronic scale is not smaller than a preset first flow threshold value, heating the heating and humidifying equipment; S4, when the flow signal of the electronicscale is smaller than a preset second flow threshold value, stopping heating the heating and humidifying equipment; and S5, after the next incoming material signal is obtained, executing the S1 againuntil production is finished. By optimizing the heating control process of the heating and humidifying equipment in the cut-tobacco dryer, steam waste caused by preheating before production, standbyafter production and the li
