蔬菜凍干機生產線也稱為蔬(shu)菜(cai)(cai)真(zhen)空(kong)冷凍(dong)(dong)(dong)(dong)干(gan)燥機。利用蔬(shu)菜(cai)(cai)凍(dong)(dong)(dong)(dong)干(gan)機的工作原(yuan)理，蔬(shu)菜(cai)(cai)通過真(zhen)空(kong)冷凍(dong)(dong)(dong)(dong)干(gan)燥技(ji)術(shu)加工處理而成凍(dong)(dong)(dong)(dong)干(gan)品，具有保存蔬(shu)菜(cai)(cai)原(yuan)有的顏色(se)、體型和(he)營養成分(fen)，復(fu)水性好，能在常溫下長時間保存。在這介紹FZG蔬(shu)菜(cai)(cai)凍(dong)(dong)(dong)(dong)干(gan)機的工作原(yuan)理和(he)結構組成。

    蔬(shu)(shu)(shu)(shu)(shu)菜(cai)(cai)(cai)凍(dong)(dong)(dong)(dong)(dong)干機(ji)的(de)(de)(de)(de)(de)工(gong)作原(yuan)理(li)是利用(yong)升華原(yuan)理(li)，根據水(shui)(shui)的(de)(de)(de)(de)(de)三相(xiang)態(tai)(tai)(tai)(tai)“液態(tai)(tai)(tai)(tai)、固(gu)態(tai)(tai)(tai)(tai)、氣態(tai)(tai)(tai)(tai)"在(zai)不(bu)同溫(wen)度和真(zhen)(zhen)空(kong)(kong)狀(zhuang)態(tai)(tai)(tai)(tai)下相(xiang)互轉換和共存的(de)(de)(de)(de)(de)特點(dian)原(yuan)理(li)。通過(guo)蔬(shu)(shu)(shu)(shu)(shu)菜(cai)(cai)(cai)凍(dong)(dong)(dong)(dong)(dong)干機(ji)的(de)(de)(de)(de)(de)制(zhi)冷系(xi)(xi)統，把(ba)(ba)含(han)水(shui)(shui)的(de)(de)(de)(de)(de)蔬(shu)(shu)(shu)(shu)(shu)菜(cai)(cai)(cai)在(zai)低溫(wen)下冷凍(dong)(dong)(dong)(dong)(dong)成(cheng)(cheng)固(gu)態(tai)(tai)(tai)(tai)，然(ran)后通過(guo)凍(dong)(dong)(dong)(dong)(dong)干機(ji)的(de)(de)(de)(de)(de)真(zhen)(zhen)空(kong)(kong)泵系(xi)(xi)統把(ba)(ba)干燥(zao)倉形成(cheng)(cheng)真(zhen)(zhen)空(kong)(kong)環境，在(zai)高(gao)真(zhen)(zhen)空(kong)(kong)狀(zhuang)態(tai)(tai)(tai)(tai)下進行一次干燥(zao)，把(ba)(ba)固(gu)態(tai)(tai)(tai)(tai)的(de)(de)(de)(de)(de)冰直接升華成(cheng)(cheng)氣體除(chu)(chu)去90%的(de)(de)(de)(de)(de)流離(li)水(shui)(shui)，再進入解析(xi)干燥(zao)需要(yao)除(chu)(chu)去剩余10%左右的(de)(de)(de)(de)(de)結(jie)(jie)合(he)水(shui)(shui)，因為(wei)結(jie)(jie)合(he)水(shui)(shui)的(de)(de)(de)(de)(de)分子力相(xiang)對(dui)強(qiang)，所以蔬(shu)(shu)(shu)(shu)(shu)菜(cai)(cai)(cai)凍(dong)(dong)(dong)(dong)(dong)干機(ji)會提供(gong)更(geng)多的(de)(de)(de)(de)(de)熱量升華除(chu)(chu)去結(jie)(jie)合(he)水(shui)(shui)，得到含(han)水(shui)(shui)在(zai)2~5%的(de)(de)(de)(de)(de)蔬(shu)(shu)(shu)(shu)(shu)菜(cai)(cai)(cai)凍(dong)(dong)(dong)(dong)(dong)干食品。蔬(shu)(shu)(shu)(shu)(shu)菜(cai)(cai)(cai)凍(dong)(dong)(dong)(dong)(dong)干機(ji)的(de)(de)(de)(de)(de)工(gong)作原(yuan)理(li)是通過(guo)三個工(gong)作階段利用(yong)升華的(de)(de)(de)(de)(de)原(yuan)理(li)除(chu)(chu)去水(shui)(shui)分，得到含(han)水(shui)(shui)極少的(de)(de)(de)(de)(de)凍(dong)(dong)(dong)(dong)(dong)干蔬(shu)(shu)(shu)(shu)(shu)菜(cai)(cai)(cai)。   蔬(shu)(shu)(shu)(shu)(shu)菜(cai)(cai)(cai)凍(dong)(dong)(dong)(dong)(dong)干機(ji)包括(kuo)凍(dong)(dong)(dong)(dong)(dong)干箱和機(ji)組架(jia)構(gou)成(cheng)(cheng)，主要(yao)是由壓縮機(ji)、真(zhen)(zhen)空(kong)(kong)泵、循(xun)環泵和PLC電(dian)控(kong)模塊(kuai)等(deng)(deng)(deng)配(pei)件，組成(cheng)(cheng)制(zhi)冷系(xi)(xi)統、真(zhen)(zhen)空(kong)(kong)系(xi)(xi)統、循(xun)環系(xi)(xi)統、電(dian)控(kong)系(xi)(xi)統等(deng)(deng)(deng)通過(guo)PLC電(dian)控(kong)控(kong)制(zhi)各系(xi)(xi)統運行。目前FZG蔬(shu)(shu)(shu)(shu)(shu)菜(cai)(cai)(cai)凍(dong)(dong)(dong)(dong)(dong)干機(ji)已廣泛應用(yong)于(yu)生菜(cai)(cai)(cai)、番茄、西蘭花(hua)、辣椒、大蔥(cong)、香菜(cai)(cai)(cai)、香蔥(cong)、花(hua)菜(cai)(cai)(cai)、洋蔥(cong)、豆角、菠菜(cai)(cai)(cai)、食用(yong)菌、山(shan)藥、胡蘿卜等(deng)(deng)(deng)蔬(shu)(shu)(shu)(shu)(shu)菜(cai)(cai)(cai)凍(dong)(dong)(dong)(dong)(dong)干加工(gong),為(wei)蔬(shu)(shu)(shu)(shu)(shu)菜(cai)(cai)(cai)深加工(gong)發展提供(gong)機(ji)遇(yu)！
