Abstract

In order to improve the drying process of fermented rapeseed meal, fermented rapeseed meal was dried by fluidized bed dryer in this study. The sampling data collected in fixed time were calculated so as to obtain the drying curve and drying rate curve of fermented rapeseed meal in the drying process. Moisture changes of fermented rapeseed meal in the drying process were analyzed based on the curve. The results showed that constant drying rate of the fermented rapeseed meal was 82.62 kg/(m2 ·h) at the temperature of 120℃. Evaporation in the constant drying stage accounted for 44.54% of the total evaporation. The drying curve and drying rate curve of fermented rapeseed meal were obtained and would provide reference for optimizing the drying process of fermented feed using fluidized bed dryer.

Key words

drying curve; drying rate curve; fermented rapeseed meal; fluidized bed dryer
