真空預冷機
蔬(shu)菜(cai)水(shui)果真(zhen)空(kong)(kong)(kong)預冷(leng)(leng)(leng)(leng)機(ji)(ji)(ji)真(zhen)空(kong)(kong)(kong)預冷(leng)(leng)(leng)(leng)機(ji)(ji)(ji)是(shi)運用(yong)真(zhen)空(kong)(kong)(kong)預冷(leng)(leng)(leng)(leng)技術，利用(yong)真(zhen)空(kong)(kong)(kong)泵抽取(qu)真(zhen)空(kong)(kong)(kong)槽內空(kong)(kong)(kong)氣(qi)和水(shui)蒸氣(qi)以(yi)降低(di)真(zhen)空(kong)(kong)(kong)箱(xiang)體內氣(qi)壓的(de)冷(leng)(leng)(leng)(leng)卻(que)(que)加工設備。在(zai)低(di)氣(qi)壓下，水(shui)的(de)沸點降低(di)，蒸發潛熱增加，被冷(leng)(leng)(leng)(leng)卻(que)(que)物(wu)表面自由水(shui)發生汽化現(xian)(xian)象(xiang)，帶(dai)走自身(shen)及(ji)壞境熱量，達到冷(leng)(leng)(leng)(leng)卻(que)(que)降溫效果。專門(men)用(yong)來(lai)防(fang)止新(xin)(xin)鮮蔬(shu)菜(cai)，水(shui)果，食用(yong)菌和新(xin)(xin)鮮農(nong)作物(wu)在(zai)采摘過(guo)程中腐(fu)爛(lan)的(de)。冷(leng)(leng)(leng)(leng)藏運輸，因(yin)此真(zhen)空(kong)(kong)(kong)冷(leng)(leng)(leng)(leng)卻(que)(que)器（真(zhen)空(kong)(kong)(kong)冷(leng)(leng)(leng)(leng)卻(que)(que)機(ji)(ji)(ji)）可(ke)以(yi)有效節約新(xin)(xin)鮮和營養價值(zhi)。真(zhen)空(kong)(kong)(kong)冷(leng)(leng)(leng)(leng)卻(que)(que)器（真(zhen)空(kong)(kong)(kong)冷(leng)(leng)(leng)(leng)卻(que)(que)機(ji)(ji)(ji)）可(ke)快速(su)消除現(xian)(xian)場熱
