| Abstract: |
| The change of moisture content of abalone in the process of microwave-vacuum drying were
researched，and the effects of microwave power，vacuum degree，loading capacity and salt solution concentration on
drying characteristics of abalone were investigated. The results showed that the drying process was divided into three
stages as follows: accelerated phase，constant-speed phase and decelerated phase. Then the relationship between
moisture ratio and drying time was studied to establish the dynamic model and verifying it. The results showed that the
dynamic model for microwave-vacuum drying of abalone was consistent with Page model，and the predictive values
were matching with measured values. So the moisture contents of abalone during the drying process can be exactly
predicted by it. |
