Because the in the outlet area 210 extracted cooling air essentially no solvent condensate is in the outlet area cooling air discharge duct 220 no condensate separator required.
- this allows the condensate separator to be made smaller than would be required if the entire cooling air extracted from the cooling zone 100 the condensate separator should happen.
- cooling air discharge duct 180 Further occurs only in the inlet area cooling air discharge duct 180 a pressure loss caused by the condensate separator on, so that to extract the cooling air from the cooling zone 100 suction fans used are correspondingly smaller can be.
- a second embodiment shown in FIGS. 12 to 14 a cooling zone 100 differs from that above described first embodiment in that the in Interior 120 blown cooling air in the inlet area 132 of the Cooling zone not through in the upper area of the cooling zone cabin 106 arranged outlet openings, but through in the lower Area of the cooling zone cabin 106 in the lower vertical Sidewall areas 144 of the inlet area 132 provided Outlet openings 224 is sucked off, the clear width is adjustable by means of sliders 225.

- the top wall 118 ′′ of the cooling zone cabin 106 is in the in 12 to 14 shown second embodiment a cooling zone 100 not angled, but flat; however, this embodiment could easily be used an angled ceiling wall can be used.
- the inlet area cooling air discharge chambers open 178 'at the rear in the conveying direction lying end of the inlet area 132 in a vertical Inlet area cooling air discharge shaft 230.
- the two Inlet area cooling air discharge shafts 230 in turn lead into an inlet area cooling air - discharge duct 180, which like the inlet area cooling air discharge duct of the first embodiment with a first condensate separator 186 and a second condensate separator 188 is provided.
- the outlet area 210 of the second embodiment also Cooling zone 100 differs from that of the first embodiment only in that the cooling air through in outlet outlet openings arranged at the lower vertical side wall regions 144 ' 232 is suctioned off.
- Which resulting changes in the structure of the outlet area 210 of the second embodiment correspond exactly to those Changes in the construction of the lead-in area described above 132, so that a detailed description of this Changes are not necessary.
