| Abstract: |
| Simulated hot air drying tests for thin layer-sliced koniak were performed by using a self-designed recycle hot air drying device under the conditions of
50℃～90℃ for air temperature,0.5～1.5 m/s for airflow velocity and 5～13 mm for
thickness of the sliced konjak.The effect of the air temperature,the airflow speed.the
slice thickness and the dryin grate was studied in particular.From an analysis of the
drying mechanism and the effect of different factors on drying process,the mathematic
model of drying rate was obtained.The results colicluded from the monte carlo method
showed that the confidence level of the model was higher than 99%.So it could quantitatively describe the changing rules of the drying rate with air temperature,airflow velocity and slice thickness. |
