The invention discloses a white spirit fragrance component separation method and device. A distillation and fractionation method is used for separating the fragrance components of white spirit. According to the distillation and fractionation method, firstly the white spirit is distilled by using a distillation apparatus, and then the distilled white spirit is subjected to fractionated treatment by using a fractionating device, wherein the fractionated treatment comprises at least three fractionated treatment links, different fractional liquid outflow temperatures are adopted at each fractionated treatment link, and front, middle and rear fragrance components in the spirit steam can be effectively separated by the control on the different fractional liquid outflow temperatures of each fractionated treatment link. The white spirit fragrance component separation device comprises the distillation device, the fractionating device and a spirit steam guiding pipe, wherein the distillation device is connected with the fractionating device through the spirit steam guiding pipe; the distillation device is used for generating the spirit steam and providing steam pressure so as to ensure that the spirit steam is transferred to a subsequent fractionated treatment link through the spirit steam guiding pipe, and the separation of different fragrance components is carried out.
