3.2.3. Phase of high transmission rate (100–190 min)
The absolute air humidity accumulated to 7.4 g kg1 at further
increasing temperatures and sloped slightly down to 7.2 g kg1 in
the second stage of the phase. The processes observed in the previous
phase were continued in the first stage of the phase to a maximum
of absolute humidity. A slight decrease in absolute humidity
in the second stage indicated that due to high water vapour transmission
more moisture was released than could be delivered by
evaporation and/or transpiration. A distinctive drop in relative
humidity at the central measuring point could be observed, accelerated
by maximum transmission rate and high intensities of condensate
formation on both the fruit surface areas and the inner tray
walls.
