对真空度影响冻干速率进行了实验研究。实验选取了三种工作压力:13.33Pa,20Pa 和26.67Pa 进行试验。结果表明,在上述压力范围内,压力越高,冻干速率越快。在更广泛压力范围内压力对冻干速率的影响,尚需进一步研究。
Experiments were conducted on the influence of vacuum on the freeze-drying rate. The experiment selected three working pressure: 13.33Pa, 20Pa and 26.67Pa for testing. The results show that in the above pressure range, the higher the pressure, the faster the freeze-drying rate. The effect of pressure on freeze-drying rate over a wide range of pressures requires further study.
