Unverified标称容量为总容积，需扣除冰量后计算实际存放空间，例如50L箱在保冷模式下实际可用约25-33L76% similarUnverified承重需求测算：一层通常需放3-5瓶调料，单瓶玻璃调料瓶约0.5-0.8kg，因此每层有效承重应≥5kg，放置油壶或大瓶酱油的层需≥8kg72% similarUnverified2人份拼盘净重（去冰去壳前毛重）应≥1kg含4-6种食材，3-4人份≥1.8kg，标称重量若含冰衣/包冰需按包冰率10-25%折算实际食材量71% similarUnverified标称容量需区分毛重与净气重，市面常见550ml罐净制冷剂约200-300g，选购时看净重（g）比看容积（ml）更能反映实际可用气量69% similarUnverified速冻虾仁分'包冰'工艺陷阱：标称500g可能含20-30%冰衣重量，看净含量和'包冰率'标注，正规产品会注明冰衣占比≤20%69% similar
