The inventor has conducted a great deal of research on the problem that the inner wall of the discharging cover of the roller is easy to stick. The inventors found that the methods for preventing the sticking of the materials used in the prior art are mainly a heating method, a coating method and a blowing method.

The heating method is difficult to realize evenly heating the whole discharging cover, some corners can still be glued, and the control of the main process temperature in the roller can be influenced by heating the discharging cover.

The spraying method is to spray an anti-sticking material on the existing equipment, the specific implementation is limited by the structure of the existing equipment, the spraying is difficult, and the sticking effect is difficult to guarantee; the spraying material may also affect the quality and food safety of the tobacco leaves, and whether the coating will fall off and the harm mixed into the tobacco leaves after falling off is also a problem to be considered in advance.

The blowing method has good effect on the timing cleaning of the fixed part, and for the large-area structure of the discharging cover and the process environment with continuous rolling, a viscosity mechanism needs to be considered, and meanwhile, the interference on the process temperature and humidity needs to be avoided, so that the blowing model is difficult to establish.

Based on the above analysis, the inventors believe that the conventional heating method, coating method and blowing method can improve the adhesion to some extent, but all have some disadvantages, and cannot achieve the ideal anti-adhesion effect.

In some embodiments of the drum outfeed hood provided by the present invention, as shown in fig. 1-3, the drum outfeed hood comprises a hood body and a release web 27, the release web 27 having a plurality of through holes 271 and being mounted to an inner wall of the hood body.
