Example 1. Moistening the redried tobacco leaves with saturated steam is to moisten the tobacco leaves by only introducing saturated steam into a first moistening device and a second moistening device of the redried tobacco leaves; the saturated steam is used for moisture regaining of the tobacco redrying, and only the saturated steam is introduced into a first moisture regaining area and a second moisture regaining area of the redrying machine for moisture regaining. The pressure of the saturated steam is 0.6-0.8MPa, the corresponding temperature is 158-174 ℃, and the pressure of the saturated steam is preferably 0.6MPa. In a first moisture return area and a second moisture return area of the redrying machine, saturated steam is blown downwards from the upper part of a mesh belt or blown upwards from the lower part of the mesh belt to remoisten the blades.
Aiming at the first and the second leaf moistening, the used leaf moistening equipment is a through-type leaf moistening machine 1, a saturated steam air supply pipe 2 is arranged in a roller of the roller-type leaf moistening machine 1, a nozzle 3 is arranged on the saturated steam air supply pipe 2, and the steam air supply pipe 2 is respectively positioned on a feed end cover 4 and a discharge end cover 5 of the roller. Through multiple tests, the optimal process requirement is that the saturated steam jet distance of the feeding end accounts for 1/2 of the barrel, and the saturated steam jet distance of the outlet end accounts for 1/4 of the barrel.
In order to realize the spraying distance, two saturated steam air supply pipes 2 are connected to a feed end cover 4 of the roller, each saturated steam air supply pipe 2 is connected with a nozzle 3, an air supply pipe and a water supply pipe are respectively arranged on the feed end cover of the roller type leaf moistening machine 1 in the prior art, the improvement mode of the feed end of the roller type leaf moistening machine 1 is that the ports of the air supply pipe and the water supply pipe which are positioned outside the roller type leaf moistening machine are connected with the saturated steam pipes, the connection of the steam air supply pipes 2 which are positioned on the feed end cover 4 in the roller is shown in figure 1, one nozzle 3 is connected to each steam air supply pipe 2, and a certain distance is reserved between the two nozzles.
