低溫冷庫的溫度是不是越低越好呢？
Low temperature cold storage temperature is, the lower the better?
低溫冷庫的溫度是在-20°C以下，因為海產(chǎn)品和冷飲需要在-20°C以下才不會變質(zhì)，低溫冷庫的特點是不定期逐步地將儀器放入冷庫，經(jīng)過一段時間冷庫的溫度達到-20°C，對這段時間沒有特殊的要求，但是對庫溫是嚴格要求，在-18°C～-23°C之間就是典型的低溫冷庫，但儲藏含乳制品的冷飲，庫溫應定在-20°C～-28°C即可，但這兩種不同的溫度需要不同等級的設備，設備投資有很大的差距。
Low temperature cold storage temperature is below - 20 ° C, because seafood and cold drinks need won't spoil under - 20 ° C, and the characteristics of the low temperature cold storage is not regular gradually the instrument into the cold storage, cold storage temperature reached over a period of time - 20 ° C, no special requirements to this period of time, but the library is strict with warm, in 18 ° C ~ 23 ° C - is a typical low temperature cold storage, cold drinks containing dairy products, but the storage library temperature should be set in - 20 ° C ~ - 28 ° C, but the two different temperature in different levels of equipment, equipment investment has very big disparity.
大多數(shù)專業(yè)制冷人士認為低溫冷庫的溫度越低越好，冰存物的保存期限可以延長，但有時應依據(jù)各種物品所需要的保存溫度而定，以蔬果類，過低的儲藏溫度易導致凍傷發(fā)生，而肉類產(chǎn)品溫度低可保存較長時間。但以經(jīng)濟與能源觀點來考慮，就應以保存時間長久來選擇低溫冷庫儲藏溫度，如肉類在-18°C下可儲存4-6個月，在-23°C下可存儲8-12個月，因為肉類在5個月內(nèi)就要到消費者手上，所以有時會考慮是否選擇-23°C的保存溫度，因此，低溫冷庫設計必須依存物的商品命周期，與其有效的保存環(huán)境來選擇合適的保存溫度。
Most refrigeration professionals think that the low temperature cold storage temperature, the lower the better, the shelf life of ice storage can be extended, but sometimes should be kept according to the various items required temperature and decide, with fruits and vegetables, easy cause frostbite, low storage temperature and low temperature meat products can save a long time. But with economic and energy point of view to consider, should choose to save the time for a long time to low temperature cold storage storage temperature, such as meat under 18 ° C can store 4-6 months, can be stored under - 23 ° C 8 to 12 months, because five months for consumers to have the meat, so sometimes will consider whether to choose - 23 ° C temperature, therefore, low temperature cold storage design must depend on content of product life cycle, and its effective the preservation of the environment to choose the appropriate temperature.
低溫冷庫預冷方法：
Low temperature cold storage method of precooling:
空氣預冷：空氣預冷方法具有空氣溫濕度易調(diào)節(jié)、可用于各種食品冷卻冷藏運輸、設備造價低等優(yōu)點。
Air precooling: air precooling method is easy to adjust, air temperature and humidity can be used for various food cooling refrigerating transportation, equipment, low cost advantages.
真空預冷：依據(jù)水隨壓力降低其沸點也降低的物理性質(zhì)，將預冷食品置于真空槽中抽真空，當壓力降低到一定數(shù)值時，食品表面的水分開始蒸發(fā)，吸收汽化潛熱，使食品自身被冷卻的方法就是真空預冷方法。
Vacuum precooling: on the basis of water with the pressure to reduce its boiling point and lower physical properties, puts beforehand LengShiPin vacuum in the vacuum tank, when pressure is reduced to a certain value, the food on the surface of the water evaporated, the absorption of latent heat of vaporization, make the food itself by cooling method is the method of vacuum precooling.
水預冷：利用水將被冷卻食品從初始溫度降至到所需要的終點溫度的方法稱為水預冷方法。
Water precooling: using the cooling water will be the food from the end of the initial temperature dropped to the required temperature method is called water precooling.
