| Summary: | 碩士 === 國立中興大學 === 農業機械工程學系 === 84 === This research measured the ERH/EMC of Longan during desorption
and adsorption processing under the 11 different temperatures
among 5C and 90C. The experimental result was analyzed through
the non-linear regression analysis of SAS software.The modified
Halsey model was suitable on the two parameters model of ERH/EMC
of Longan during desorption and adsorption processing. The
modified Oswin model was suitable on the three parameters model
of ERH/EMC of Longan during desorption and adsorption
processing.The mathematics equations of those two modified
models were established on this research.The Hystersis
phenomenon of Longan was happened between 5c and 90C during
storage.The lowest limit for hysteresis appearance occurred at
0.1 moisture(dry base) and 0.2 RH.The relative humidity range of
converging beginning of hystersis loop increase as higher
temperature and its moiisture range was between 0.18 and
0.22(dry base)
