鲜切花真空预冷过程温度的红外热成像检

Detection of Cut Flower during Vacuum Cooling with Thermal Infrared Image

摘要:

采用红外热成像远程动态控制系统和热电偶两种温度检测方法，对非洲菊真空预冷过程中舌状花瓣、管状花瓣和茎秆3个部位的温度进行实时检测。实验结果表明，不同部位之间降温速率存在较大差异，不同部位的温度分布也不均匀；热电偶和红外热成像检测结果相比，前者比后者平均高出

Abstract:

4.55～10.4℃。 Both thermal infrared imaging and thermocouples were applied to real time measurement of cut gerbera during vacuum cooling. Surface temperatures of the ligule-shape petal, tubular petal and stem were detected. Results show that there is a significant difference of different parts in average cooling rate, and for the petal and stem, the temperature distribution is nonuniform. The average final temperature obtained with thermal images is 4.55～10.4℃ lower than the thermocouple.
