The invention provides a sail type three-dimensional yellow sun-cured tobacco modulation facility which comprises a main body framework, wherein the main body framework adopts a cuboid structure and consists of a plurality of scaffold steel pipes which are fixedly encircled through scaffold fastening pieces; a canopy and a rainproof curtain are arranged on the outer side of the main body framework; an upper guide rail and a lower guide rail are respectively and longitudinally arranged at the top end and the bottom end of the main body framework; eudipleural upper telescopic devices are arranged on the upper guide rail and are connected with each other through a smoke curtain hanging device; eudipleural lower telescopic devices are arranged on the lower guide rail; the upper telescopic devices and the lower telescopic devices are respectively connected with a traction device through steel wire ropes. Compared with the prior art, the sail type three-dimensional yellow sun-cured tobacco modulation facility is reasonable in design and convenient to operate; the upper telescopic devices and the lower telescopic devices are adjusted by a traction device through the steel wire ropes, so that interval adjustment is performed on yellow sun-cured tobaccos in different modulation stages, the sun-curing quality is improved, and the loss caused by bad weather is reduced; the place can be reduced, the labor intensity is alleviated, the sun-curing efficiency is improved, and large-scale production is realized.
