Based on the response surface central composite design theory, the passage discusses the effects of microwave power, slice thickness and the pulse ratio on ginger intermittent microwave drying process through response surface methodology. Simultaneously we establish quadratic polynomial regression model and optimize the drying process parameters. Results show that the influence of 3 factors on the comprehensive evaluation: The slice thickness > Microwave power > The pulse ratio. The best process parameters of ginger intermittent microwave drying is: microwave power 515W, the slice thickness 2mm, the pulse ratio 45s and the maximum comprehensive score is 0.96. |
