方艙凍干機液氮制冷技術

 

 

  方艙凍干機工藝一些方面還有一個種液氮制熱。   在便捷解封下，主要是因為解封傳輸速度高，工作溫度低，組織細胞室內外的土壤含水量近乎也折出大規模的冰晶核，造成狗狗細小均勻的地域分布的針狀警醒，因而很大程度上減退或常規上盡量不要因有冰致使的解封澎漲，快速快速解凍后盡管難免會有液汁引流，但和慢凍相比之下卻少的多。因為，速凍食物食物快速快速解凍后的之島和風味菜也行得多。所有如果提升解封傳輸速度是提升的產的品效率的主要，也是實驗食物解封長效機制的原則。

  目前方艙凍干機，最常用(yong)的(de)(de)(de)速(su)(su)(su)凍(dong)(dong)(dong)(dong)(dong)(dong)設備(bei)有(you)接(jie)觸(chu)式(shi)平板凍(dong)(dong)(dong)(dong)(dong)(dong)結器，吹(chui)風半(ban)姐促(cu)使凍(dong)(dong)(dong)(dong)(dong)(dong)結器機(ji)螺旋式(shi)吹(chui)風凍(dong)(dong)(dong)(dong)(dong)(dong)結器，這些(xie)速(su)(su)(su)凍(dong)(dong)(dong)(dong)(dong)(dong)設備(bei)都采用(yong)機(ji)械式(shi)制冷(leng)(leng)系統(tong)，利(li)用(yong)氟利(li)昂作為(wei)(wei)制冷(leng)(leng)劑(ji)，凍(dong)(dong)(dong)(dong)(dong)(dong)結溫度(du)(du)(du)一般為(wei)(wei)-30～-40℃。采用(yong)低溫冷(leng)(leng)凍(dong)(dong)(dong)(dong)(dong)(dong)系統(tong)凍(dong)(dong)(dong)(dong)(dong)(dong)結食(shi)品(pin)(pin)(pin)，凍(dong)(dong)(dong)(dong)(dong)(dong)結溫度(du)(du)(du)低，因為(wei)(wei)凍(dong)(dong)(dong)(dong)(dong)(dong)結速(su)(su)(su)度(du)(du)(du)快，所費時(shi)間(jian)短(duan)。但是由(you)于二氧化碳(tan)(tan)和液(ye)(ye)氮作為(wei)(wei)冷(leng)(leng)凍(dong)(dong)(dong)(dong)(dong)(dong)介質，它(ta)們的(de)(de)(de)溫度(du)(du)(du)分別為(wei)(wei)-78.47℃和-196攝氏(shi)度(du)(du)(du)。采用(yong)低溫冷(leng)(leng)凍(dong)(dong)(dong)(dong)(dong)(dong)系統(tong)凍(dong)(dong)(dong)(dong)(dong)(dong)結食(shi)品(pin)(pin)(pin)，凍(dong)(dong)(dong)(dong)(dong)(dong)結溫度(du)(du)(du)第，因為(wei)(wei)凍(dong)(dong)(dong)(dong)(dong)(dong)結速(su)(su)(su)度(du)(du)(du)快，所費時(shi)間(jian)短(duan)。但是由(you)于二氧化碳(tan)(tan)的(de)(de)(de)純度(du)(du)(du)問題，使得(de)這種(zhong)裝(zhuang)置的(de)(de)(de)應用(yong)并不十(shi)分廣泛。液(ye)(ye)氮具有(you)無(wu)(wu)毒、無(wu)(wu)謂、無(wu)(wu)色(se)、非典第、不污染環境等特點，有(you)著其他制冷(leng)(leng)劑(ji)無(wu)(wu)法比你的(de)(de)(de)優越(yue)性。由(you)于液(ye)(ye)氮價格(ge)較貴(gui)，凍(dong)(dong)(dong)(dong)(dong)(dong)結食(shi)品(pin)(pin)(pin)的(de)(de)(de)成(cheng)本(ben)較高，液(ye)(ye)氮速(su)(su)(su)度(du)(du)(du)設備(bei)在個國內目前還未(wei)普及(ji)，隨(sui)著空分技術的(de)(de)(de)發展液(ye)(ye)氮產品(pin)(pin)(pin)數量(liang)大幅度(du)(du)(du)上升(sheng)，價格(ge)也(ye)趨(qu)于便宜，液(ye)(ye)氮冷(leng)(leng)凍(dong)(dong)(dong)(dong)(dong)(dong)技術及(ji)設備(bei)必(bi)會在食(shi)品(pin)(pin)(pin)速(su)(su)(su)度(du)(du)(du)行業中有(you)著廣闊(kuo)的(de)(de)(de)前景(jing)。

  液氮制冷壓縮機機技巧用途不是常大范圍和有預知性的，末來根據惰性甲烷氣體的用途，N2的發展，一定的會加快制冷壓縮機機業內的發展潛力與末來。
