摘要
为了解杏鲍菇在真空微波干燥过程中水分含量的变化,进行了真空微波干燥试验,获得了不同真空度(-50、-70、-85kPa)、微波功率(250、750、1250W)及装载量(50、100和150g)对杏鲍菇真空微波干燥特性的影响。结果表明,杏鲍菇真空微波干燥过程符合Page方程(P<0.05),该模型可较准确地预测杏鲍菇在真空微波干燥过程中的含水率和失水速率。本研究为杏鲍菇真空微波干燥过程的优化和控制提供了理论依据。
The experiments of vacuum microwave drying P.eryngii were conducted for study rules of moisture change.The effect of different vacuum degree,microwave power and loadage on vacuum microwave drying characteristics of P.eryngii was researched,and a drying dynamics model was established.The results showed that the drying dynamics model of vacuum microwave drying Pleurotus eryngii agreed with Page equation（P〈0.05）,which could accurately estimate the moisture contents and dehydrating rate during vacuum microwave drying process.This study provided a theoretical basis for the optimization and control of vacuum microwave drying process.
