Explanation: — The drying room is surrounded 

 by a floor corresponding in size to the sub- * 

 structure and lies at an average distance of 1 i 

 metre over the pipes. Each side is divided fc- 

 into 10 single chambers each T32 m. by 0-54 m.|£ 

 In each of these chambers can be placed, one 

 over the other, as many as 13 trays with bottoms 

 of wire-netting. The chambers have no bot- "r 

 torn and the trays are prevented from falling into 

 the heating-room by supports running equila- ' * 



terally right round the sides (a). The door C 

 which can be lifted oft' and is held in position 

 above and below by wooden fasteners constitutes 

 the outside end of the chamber. From the door 

 upwards the structure is boarded, the boards 

 as well as the interior wall B reaching 4 metres 

 to the roof. 



The drying chamber itself is covered in above 

 by perforated boards running parallel to the 

 trays.
