摘要
以熟肉为实验材料,对真空冷却过程中真空室内温度变化进行了实验研究。结果发现:真空冷却过程中真空室内的温度会出现一些波动,其变化过程可以分为四个阶段:真空室内的温度从15.8℃一直降低到10.7℃;然后从10.7℃升到最高的19.1℃;随着产品温度的降低以及真空室内压力的降低,真空室内的温度从最高的19.1℃降低到最低的6.1℃;最后,由于真空室内放气阀的开启,使得真空室的温度从最低的6.1℃升高到最终的13.1℃,一直保持在真空冷却过程结束。
In this paper,vacuum cooling of cooked meat was carried out to investigate the variations of temperature in the vacuum chamber.The experimental results show that the chamber temperature has some fluctuations during vacuum cooling,the variation of temperature in the vacuum chamber includes four different phases:(1) the reduction of the initial chamber temperature from 15.8℃ to 10.7℃;(2) the increment of the chamber temperature from 10.7℃ to the maximum temperature 19.2℃;(3) the reduction of the chamber temperature from the maximum 19.2℃ to the minimum 6.1℃;(4) the increment of the chamber temperature from the minimum temperature 6.1℃ to the final chamber temperature 13.1℃.
