| abstract |
This invention relates to a process for drying goods (1) with iutt which is circulated around and / or through the goods (1), wherein the drying comprises at least two dough processes (A, B) and where the circulation liquid in the respective dough process (A, B) conditioned to substantially different wet temperatures (TvA, TvB). Energy recovery takes place by dividing the circulation air in the one-day process (A, B), the one with a higher wet temperature (TvA, TVB), into at least two quantities (3, 4), where a quantity (3) is dehumidified by condensation, where energy obtained by the condensation is transferred tiii the second dei process (A, B), tiii the circulation water with specific water temperature (TvA, TvB) ecn where the rest of the amount (4) of the circulation air ieds past the 1G condensation. The invention also relates to an energy recovery system (2) and a drying device (19), (See Fig. 1.) |
