摘要
为提高葛根干燥品质和效率，研究了微波和热风联合应用于葛根干燥的最优工艺，并建立数学模型对干燥全程进行预测和模拟。结果表明，葛根微波-热风联合干燥的最优工艺为：先以微波功率320w干燥2min，再在55℃热风下干燥40min。干燥的前期（0～2min）可用Page模型描述，后期（2-40min）用HendersonandPabis模型描述。
The microwave and heated-air joint applied in Radix Puerariae drying was studied to improve the drying efficiency and quality, and mathematical modeling was used to simulate the whole drying process. The results showed that the optimal drying process was to start with 320 W microwave 2 min, then turn in 55 ℃ heated-air for 40 min. The microwave drying process could be described with Page equation, and the heated-air drying process could be described with Henderson and Pabis equation.
