真空包裝機(ji)廠的(de)真空(kong)包裝機增加充(chong)(chong)(chong)氣(qi)(qi)(qi)功(gong)能(neng)是(shi)(shi)有兩種(zhong)方(fang)式，一種(zhong)是(shi)(shi)氣(qi)(qi)(qi)嘴直(zhi)接伸到產(chan)品(pin)袋子(zi)里(li)面進(jin)行充(chong)(chong)(chong)氣(qi)(qi)(qi)的(de)，另一種(zhong)是(shi)(shi)把要(yao)充(chong)(chong)(chong)的(de)氣(qi)(qi)(qi)體先充(chong)(chong)(chong)滿整個真空(kong)室，然后靠負壓(ya)差(cha)充(chong)(chong)(chong)滿袋子(zi)。那(nei)究竟采用哪種(zhong)方(fang)式充(chong)(chong)(chong)氣(qi)(qi)(qi)好(hao)呢，這(zhe)里(li)主(zhu)要(yao)看客戶的(de)產(chan)品(pin)性(xing)質，單(dan)純(chun)來說肯(ken)定是(shi)(shi)直(zhi)接沖到袋子(zi)里(li)比(bi)較好(hao)，這(zhe)樣置換的(de)又純(chun)還能(neng)省不少氣(qi)(qi)(qi)源，但是(shi)(shi)大家(jia)一定要(yao)考慮好(hao)自(zi)己產(chan)品(pin)性(xing)質。如(ru)果產(chan)品(pin)是(shi)(shi)顆粒，我(wo)們可以(yi)采取起(qi)初一種(zhong)方(fang)法(fa)直(zhi)接讓充(chong)(chong)(chong)氣(qi)(qi)(qi)嘴到袋子(zi)里(li)進(jin)行充(chong)(chong)(chong)氣(qi)(qi)(qi)，但是(shi)(shi)如(ru)果你的(de)產(chan)品(pin)是(shi)(shi)粉末狀的(de)就不能(neng)用起(qi)初一種(zhong)方(fang)法(fa)了，需要(yao)第二種(zhong)在真空(kong)室充(chong)(chong)(chong)氣(qi)(qi)(qi)利用壓(ya)力(li)差(cha)充(chong)(chong)(chong)滿袋子(zi)。可是(shi)(shi)客戶又要(yao)要(yao)求達到一定比(bi)例(li)的(de)殘氧量，這(zhe)就很矛(mao)盾了。
