摘要: 旨在研究经过渗透预处理的樱桃番茄在微波真空干燥过程中的水分变化规律。对渗透预处理樱桃番茄进行微波真空干燥，绘制不同微波功率、真空度、装载量条件下的干燥曲线和降水速率变化曲线，对试验数据进行拟合，建立干燥动力学模型。结果表明，樱桃番茄微波真空干燥过程符合Page方程，该模型可较准确地预测樱桃番茄在微波真空干燥过程中的水分变化规律，为樱桃番茄的微波真空干燥过程的优化和控制提供了理论依据。Abstract: The drying process and kinetics of the microwave-vacuum dehydration on the osmotically pretreated cherry tomatoes (Lycopersicon esculentum var. Cerasiforme)were studied. Varied microwave power, vacuum and feeding loads were applied in the experimentto generatea kinetics model for the process. The Page model was found to best describethe process with an accurate prediction on the water loss in the tomatoes. The result paved the way for the optimization and control of the microwave-vacuum dehydrationtechnology.
