响应曲面法优化硫酸铵微波干燥工艺
Optimization of microwave drying process for ammonia sulfate with response surface methodology
摘要
Abstract
A new technology of microwave drying ammonium sulfate was studied.The effects of drying temperature,microwave drying time, material mass and thickness on the relative dehydration rate of ammonium sulfate were investigated.On the basis of single-factor experiment, the response surface central composite design was adopted to optimize the microwave drying technology parameters of ammonium sulfate by taking the relative dehydration rate of ammonium sulfate as response value.The optimized technology parameters include the temperature 86.05 ℃,radiation time 190.50 s, material mass 102.59 g, and material thickness 20.55 mm.The corresponding relative dehydration rate of the material is 99.29％.The deviation of experimental values and predicted values is only -0.43％, showing a high reliability.The results show that the response surface central composite design plays good optimization and prediction roles.The technology of microwave drying ammonium suffate used is reasonable and feasible, which can provide reference and guide for future research.关键词
