冷链一直以来都是食品冷冻环节的重中之重。作为以制冷技术为主要手段的食品保鲜模式，食品冷链从根本上解决了由供应至最终销售环节食品质量受到不良影响的问题，其也是将食品损耗程度降低的关键因素，无论哪一个阶段出现了问题均会对食品冷链产生难以预估的严重后果。“,”The cold chain has always been the top priority of the food freezing process. As a food preservation model with refrigeration technology as the main method, the existence of the food cold chain fundamentally solves the problem of adverse effects on food quality from supply to final sales. The problem is also a key factor to reduce the degree of food loss. No matter which stage of the problem occurs, it will have serious consequences that are difficult to predict in the food cold chain.
