| Abstract: | A set of experiments designed by the single factor test and the orthogonal test was carried out on a lab scale vacuum - freeze dryer in this paper, and the eutectic point of cucumber measured by the electric resistance was - 26.5 ℃. The analysis of the experimental results showed that the optimum technical conditions of the freeze drying sure was as follow： heating temperature of shell was 50℃, the sample layer thickness was 8mm, the hothouse pres- 35Pa. , and freeze temperature was -50℃. |
