  • the modular chamber dryer system of Figures 7 and 8th had the particular advantage that the stand area 7 could be used optimally. That is to say that twice as many workpieces 2A and 2B could be processed on the same area 7 as with a one-story structure.
  • the modular chamber dryer system 1 of the Figure 9 had no functional interspaces 5 between the subunits 1.1 + 1.2, but rather two adjacent subunits 1.1 + 1.2 were thermally insulated from one another by a thermally insulating partition 12. Instead of the functional intermediate spaces 5, there were functional structures 13 on the outer roofs 1.1.9 and 1.2.9 - structures 13.1 for the chamber dryer 1.1 and structures 13.2 for the cooling chambers 1.2 -. These took over the functions of the functional spaces 5.
