Cut tobacco over-dried temperature and pressure increasing pipeline type conditioning system

The invention discloses a cut tobacco over-dried temperature and pressure increasing pipeline type conditioning system. The system is additionally arranged beside a main production line, and comprises a feeding conveying belt, a conditioning device, a gas and material separation chamber and a discharging conveying belt, wherein the feeding conveying belt, the conditioning device, the gas and material separation chamber and the discharging conveying belt are connected in sequence; the conditioning device comprises an atomizing nozzle, an initial conditioning barrel, a steam nozzle and a conditioning chamber; the atomizing nozzle is positioned above the initial conditioning barrel; a gas lock is arranged at the bottom of the initial conditioning barrel; the steam nozzle and the initial conditioning barrel chamber are positioned below the initial conditioning barrel. The system realizes rapid and uniform conditioning of over-dried cut tobacco through cut tobacco initial conditioning and temperature and pressure increasing pipeline type conditioning, reduces the conditioning time, realizes the same batch conditioning, reduces breakage of over-dried cut tobacco, guarantees the completeness of cigarette blend, and reduces the influence on the sensory quality of cut tobacco.
