食品冷链新技术研究进展

食品冷链是以保证易腐食品品质为目的，以保持低温环境为核心要求的供应链系统，冷链基本流程包括低温加工、低温储存、低温运输与配送、低温销售四个方面。本文对冷链的各环节出现的新技术进行了研究，包括空气循环制冷技术、超冰温技术、冷藏运输吸收式制冷技术、超市用CO2制冷技术等。希望通过本文的研究可以对冷链的发展起到促进的作用。

Research on the New Technology of the Food Cold Chain

Food cold chain which including four steps of production and processing, food storage, distribution and transportation, consumption, the main purpose to ensure the quality of perishable food and maintain low-temperature of environment. The paper introduce the new technology of each step of the cold chain, including the air cycle refrigeration technology, Super-cooled technology, absorption refrigeration technology for transportation, supermarket CO2 refrigeration technology, etc. All these work will make a contribution to develop the cold chain system.
