| Abstract: | Effects of the material thickness,drying chamber pressure and board temperature on the area shrinking rate of vacuum freeze-drying of panax ginseng were investigated with the three-factor second order general revolving combination design,thus the regression model was obtained between the area shrinking rate and the factors.The experimental results show that the most important factor affecting the area shrinking rate is material thickness followed by heating temperature,drying chamber pressure.The optimized combination of factors is material thickness of 12mm,heating temperature of 40℃,and drying chamber pressure of 40Pa,respectively. |
