    摘要:

    為了揭示真空預冷機理，優(yōu)化真空預冷設(shè)備，需要實時測量真空預冷過程中真空室中的壓力、捕水器的溫度、果蔬的溫度和質(zhì)量等多個參數(shù)的變化。本文簡述了自行設(shè)計的真空預冷實驗裝置的組成及設(shè)備的數(shù)據(jù)采集系統(tǒng)。將質(zhì)量傳感器成功地引入真空室，完成了產(chǎn)品質(zhì)量在真空預冷過程中的在線監(jiān)測。

    Abstract:

    To explore the mechanics of vacuum cooling and optimize vacuum precooling instrument, the real-time measurement of the variation of multi-parameters such as the pressure in the vacuum chamber, temperature of the condenser, temperature and mass of fruits and vegetables during vacuum cooling was necessitated. The self-designed vacuum cooling set up and the data acquisition processing system were presented. It was the weight sensor innovatively taken into the vacuum chamber that realized the online measurement of product quality during vacuum cooling.
