| China is rich in rape, its yield and acreage is the biggest in the world. In order to ensure the drying quality,
improve the drying efficiency, and reduce the drying energy consumption, a new method to dry rapeseed was proposed
under the low -temperature and dehumidification conditions. Designed a low -temperature and dehumidification drying
system, carried out some contrasting experiments under low-temperature (45, 55, 65益) and high temperature (80, 105, 120,
150益), established the low -temperature and dehumidification drying mathematical model of rapeseed and tested its
reliability. The results showed that the drying mathematical model of rapeseed fitted the Page model; drying temperature
and relative humidity were the two main factors influencing the drying efficiency under the same wind speed condition;
near-infrared analysis results showed that protein and oleic acid content increased slightly under the low-temperature and
dehumidification condition; the germination rate experiments showed that the germination rate of low -temperature
dehumidification drying was significantly higher than that of the high temperature.
