tilapia fillets osmotic microwave drying
研究3mm.5mm、10mm及渗透后含水率为70.87%、62.17%、51.49%的罗非鱼片分别在200W.400W,600W,lfg~s.O率下的干燥特性。当初始含水率较高时,增大微波功率,可以提高干燥速率,明显缩短干燥时间,但当含水率较低时,增大微波功率,干燥速率却降低。鱼片含水率越低,厚度对微波干燥的影响越小。此外,通过对实验数据进行拟合,得到渗透后微波干燥模型。

characteristics of drying different thickness (3mm. 5ram, 10mm) and Water content (70.87%, 62.17%. 51.49%) of Tilapia fillets are stud- ied by osmotic-microwave and the microwave Power are 200 W, 400 W, 600 W. Drying rate are increasing with the microwave power When the initial moisture content is high and the drying time was shorter more obviously. However, the drying rate is decreased when increasing the microwave power as the water content is low. The lower water content is, the effect of thickness on drying is lower. In addition, osmotic-microwave model is obtained by fitting experimental data.
