如何选择气调保鲜包装机首先就要了解气调保鲜包装机，只有了解什么是气调保鲜，真正了解起到保鲜后再选择合适自己的设备： 1、气调保鲜包装机须有高精确度的气体自动混合装置，其精度控制要求精确，大误差率应≤2.0%，理想状态≤1.0%。 气调保鲜的关键是根据不同食品的特性采用配比精确的复合保鲜气体，比如上海青的保鲜，其气体混合比为O2:4-5%；CO2:1-2%，伤害浓度为5%；N2:95-97%，如O2含量低，会造成无氧呼吸而坏死，而O2或CO2含量高又无法抑制呼吸速度，影响保鲜期；当CO2超过其伤害浓度，会兰花的、变质。因，气调保鲜包装机的核心技术是必须具有高精确的气体自动混合装置；气调保鲜包装

As we all know, aquatic products are highly perishable items, and once the freshness deteriorates, its value will drop a lot, and it may even lose its edible value completely and cause significant economic losses. Therefore, the corresponding fresh-keeping treatment should be taken in time for the f
