Abstract
℃℃℃ desorption drying is 2h, and the temperature is 5 0. The total ℃ time is 11h. The freeze-drying process curve is given. The quality of the freeze-dried fragrant pear was tested and the result is comparatively well. By a series of experiments, the effect of freeze-drying parameters on the freeze-drying time and product quality were discussed, the parameters including the freezing rate, heating temperature, pressure of drying chamber and thickness.
