中文摘要:果蔬活组织冰点温度的测量对于研究果蔬组织低温冷害和冻害机理以及冷冻加工过程具有重要意义。针对传统方法测定果蔬汁液的冰点温度与活组织的冰点温度有很大差异以及通过直接将热电偶或热电阻插入果蔬组织进行测试,受果蔬本身形状尺寸影响较大,难以有效指导生产实际的问题,设计了一种基于传热学一维半无限大平板非稳态导热原理,利用半导体制冷技术进行果蔬活组织冰点测试的系统和方法。实验结果证明该系统用来测试果蔬活组织冰点既方便又可靠,同时设备简单、测试时间短、样品需要量少、环境的热扰动影响小,具有良好的应用前景。

Abstract:Measurement of freezing point temperature for living tissue of fruits and vegetables plays an important role for study on chilling, freezing injury mechanism and freezing process of fruits and vegetables. The freezing point temperature obtained by traditional measurement methods is difficult to be used to direct industrial process, because the temperature is from fruit and vegetable juice temperature, has great difference with the freezing point of living tissue, and is greatly influenced by the shapes and sizes of fruits and vegetables by putting the thermocouple or thermal resistor into fruit and vegetable tissues. The measurement system for freezing point of living tissue of fruits and vegetables was developed based on one dimension unsteady state semi-infinity heat conduction theory. The results show clearly that this measurement is convenient and reliable for determining freezing point of living tissue of fruits and vegetables. It is convenient, time saving, samples saving and environment thermal disturbance less. It has a good application prospect in determining freezing point of fruits and vegetables.

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
