It forms.
The utility model has the beneficial effects that：
The utility model is arranged using multistage lifting blade, and lifting blade height increases step by step, and material enters cylinder feed zone
When, moisture highest, and the wind-warm syndrome that hot wind enters in cylinder is successively decreased from feed zone to discharging region, rotating speed is consistent
In the case of the linear velocity that is obtained of the lower lifting blade of height it is lower, material from feed zone to discharging region residence time according to
Secondary reduction ensure that drying effect, meanwhile, the linear velocity from feed zone to discharging region lifting blade is gradually increased so that object
Expect in acceleration mode step by step so that effectively lifting area is promoted step by step, is conducive to be scattered area and the reduction heat sky that increase material
Hole phenomenon so that into being more evenly distributed, rationally on cylinder sectional area of the material in cylinder, reached better calorific value profit
With rate.
