A rotary plate on one side of the post-drying chamber I is used as a partition between the two hemispherical inner walls of the above-mentioned rotary drum on the chambers I and ΠΙ. At 85, when the drum is at a standstill in such an embodiment, the space between the position shown in FIG. Due to the fact that the rotary drum in FIG. 5 is better utilized than in the case of the executors of a vertical plane (when the rotary drum forms according to FIGS. 4 to 6 are stationary.
