[0003] Tobacco stems are an important component of tobacco leaves. After separating the leaves from the stems, tobacco stems, which make up about 25% of the tobacco leaf weight, can be obtained. These stems can be used to make stem strips or to produce reconstituted tobacco. In the process of making stem strips, the stems are first moistened with water to swell, then extruded into sheets for slicing. Finally, they are heated and pressurized, then quickly depressurized to further expand them. In the process of producing reconstituted tobacco, a steaming process is used to reduce the off-flavors of the stems and improve the sensory quality of the reconstituted tobacco.
[0004] There are three main types of equipment for heating and pressurizing tobacco stems: spiral stem steaming machine, tunnel stem steaming machine, and scraper stem steaming machine. All of these are continuous production equipment. These machines can meet the needs of continuous production lines, but they have shortcomings such as unstable stem steaming pressure, short stem steaming time, and relatively low stem steaming pressure. Utility Model Content

[0009] Further, the rotating speed of the rotating mechanism of the steaming machine is 10-30 revolutions per minute.
[0010] Further, the mesh size of the lining net in the steaming frame is 12-16*12-16 mm.
[0011] Further, the steam inlets are arranged at the bottom of the steaming machine, and one is arranged at the front, middle and rear of the axial direction of the steaming machine.
[0012] Further, the width of the steaming frame compression mechanism is greater than the width of the steaming frame by 2-3 cm.
