冷链是由各个环节组成的农产品冷藏保鲜系统。苹果采后进入流通的第一个环节是预处理和包装运输技术。本文主要研究红星苹果经水预冷后用冷藏箱和冷藏汽车长途运到销地冷风库贮藏的效果。研究证明,红星苹果经水预冷后进行冷藏运输,是果品冷藏链的重要环节。一、试验内容及方法 (一)水预冷流水线的研制和组成水预冷流水线是利用水导热快的道理自行设计 Cold chain is composed of all aspects of agricultural refrigeration system. The first part of Apple’s post-harvest circulation is pretreatment and packaging and transportation. This paper mainly researches on the effect of Red Star apple pre-cooling with water and storing it in cold storage with long-distance refrigerated containers and refrigerated vehicles. Studies have shown that Red Star apple cold water transport after precooling is an important link in the cold chain of fruits. First, the test content and methods (a) water precooling line development and composition of the water precooling line is the use of water-based thermal fast design truth
