The invention discloses a flue-cured tobacco variety yunyan99 flue-curing process, which comprises steps of fire making and temperature control, tobacco leaf yellowing, transition, tobacco leaf color fixing and tobacco leaf rib drying. On the basis of the traditional three-stage tobacco leaf flue-curing process, according to the flue-cured tobacco variety yunyan99 tobacco leaf features and qualities, the upper yunyan99 tobacco leaf flue-curing process, the middle yunyan99 tobacco leaf flue-curing process and the lower yunyan99 tobacco leaf flue-curing process are creatively divided into five steps and three stages according to changes of factors such as temperature and humidity, and according to tobacco leaf change requirements at each stage, temperature and humidity indexes are specified, heat supply and proper ventilation are carried out, the tobacco leaf quality can be effectively presented and can be in line with the international general advanced flue-curing level. The process has the advantages that the operation is simple, convenient, safe and secure; operability is strong; color fixing of the tobacco leaf can be kept stable; the leaf has a good shrinkage degree; and the oil content and the tobacco leaf aroma concentration are greatly improved.
