隨著時代的發展，技術的進步，包(bao)裝(zhuang)(zhuang)機械在(zai)包(bao)裝(zhuang)(zhuang)領域中(zhong)正起著越來越大(da)的作(zuo)用(yong)(yong)(yong)(yong)，真空(kong)(kong)(kong)包(bao)裝(zhuang)(zhuang)也稱減(jian)壓(ya)包(bao)裝(zhuang)(zhuang)，是將包(bao)裝(zhuang)(zhuang)容器內(nei)(nei)的空(kong)(kong)(kong)氣全部抽(chou)出(chu)密封，維持袋內(nei)(nei)處(chu)于高度減(jian)壓(ya)狀態，空(kong)(kong)(kong)氣稀少(shao)相當于低氧(yang)效果，使(shi)微生(sheng)物沒(mei)有生(sheng)存(cun)條件，以達到(dao)果品新鮮、無(wu)病腐發生(sheng)的目(mu)的，目(mu)前應用(yong)(yong)(yong)(yong)的有塑料袋內(nei)(nei)真空(kong)(kong)(kong)包(bao)裝(zhuang)(zhuang)、鋁箔包(bao)裝(zhuang)(zhuang)、玻(bo)璃器皿、塑料及(ji)其復合(he)材料包(bao)裝(zhuang)(zhuang)等，可根(gen)據物品種類選擇包(bao)裝(zhuang)(zhuang)材料，由(you)于果品屬(shu)鮮活食品，尚在(zai)進行呼吸作(zuo)用(yong)(yong)(yong)(yong)，高度缺氧(yang)會造成生(sheng)理病害(hai)，因此，果品類使(shi)用(yong)(yong)(yong)(yong)真空(kong)(kong)(kong)包(bao)裝(zhuang)(zhuang)的較少(shao)。下(xia)面中(zhong)山市科萊(lai)森自(zi)動化機械有限公司小(xiao)編(bian)為大(da)家介紹(shao)一下(xia)真空(kong)(kong)(kong)包(bao)裝(zhuang)(zhuang)機的用(yong)(yong)(yong)(yong)途、特(te)點、操作(zuo)步驟、技術解析、作(zuo)用(yong)(yong)(yong)(yong)機理、選用(yong)(yong)(yong)(yong)原則(ze)、維護保養。
