美国休斯飞机公司研究出一种超导电磁致冷冰箱,具有体积小,重量轻,无噪声,无泄漏,安全可靠,结构简单等特点,箱内温度可达-273℃,价格比普通冰箱便宜四分之一。据报道,英国的苹果有八成采用气调冷藏,美国则为三成半。另据报道,果蔬类采用减压冷藏的效果比气调冷藏好,贮藏期可延长一半,且蔬菜的味道与新鲜的没有区别,减压冷藏也可用于鲜肉保存,效果比速冻肉食要好。味道也鲜美得多。日本大工公司研制出一种喷涂-40℃～-50℃液体冷冻食品的快速冷冻装置,冷冻时间只需普通的二十分之一,这种液体内含有乙烯酒精,丙烯甘醇和苹果酸等,可冷却到-50℃和重复使用。
American Hughes Aircraft Company developed a superconducting magnetic refrigerator, with small size, light weight, no noise, no leakage, safe and reliable, simple structure, the temperature inside the box up to -273 ℃, the price is lower than ordinary refrigerators One quarter cheaper. It is reported that 80% of British apples adopt chilled atmosphere while in the United States, they are 30%. It is also reported that the fruits and vegetables adopt the effect of decompression refrigerating better than the air conditioning refrigerated, the storage period can be prolonged by half, and the taste of the vegetables is the same as that of the fresh ones. The decompression refrigerating can also be used for preserving the fresh meat, and the effect is better than the frozen meat. Taste is also much more delicious. Japan’s largest industrial company developed a spray -40 ℃ ~ -50 ℃ liquid frozen food rapid freezing device, freezing time only ordinary one-twentieth, this liquid contains ethylene alcohol, propylene glycol and malic acid, etc., Can be cooled to -50 ℃ and reused.
