真空(kong)包裝機廠的真空包(bao)裝機(ji)增(zeng)加充(chong)(chong)(chong)氣功能(neng)(neng)是有兩種(zhong)(zhong)方(fang)式(shi)，一(yi)(yi)種(zhong)(zhong)是氣嘴直接伸到產品(pin)袋子(zi)(zi)里(li)(li)(li)(li)面進(jin)行充(chong)(chong)(chong)氣的，另一(yi)(yi)種(zhong)(zhong)是把(ba)要(yao)(yao)(yao)充(chong)(chong)(chong)的氣體先充(chong)(chong)(chong)滿(man)整個真空室(shi)，然后靠(kao)負壓差(cha)充(chong)(chong)(chong)滿(man)袋子(zi)(zi)。那究(jiu)竟采用哪(na)種(zhong)(zhong)方(fang)式(shi)充(chong)(chong)(chong)氣好呢，這里(li)(li)(li)(li)主要(yao)(yao)(yao)看(kan)客(ke)戶(hu)的產品(pin)性質(zhi)，單純來說肯定是直接沖(chong)到袋子(zi)(zi)里(li)(li)(li)(li)比(bi)較好，這樣置換的又純還能(neng)(neng)省不少氣源，但(dan)(dan)是大(da)家一(yi)(yi)定要(yao)(yao)(yao)考(kao)慮好自(zi)己(ji)產品(pin)性質(zhi)。如(ru)果產品(pin)是顆粒，我們可以采取起初一(yi)(yi)種(zhong)(zhong)方(fang)法(fa)直接讓充(chong)(chong)(chong)氣嘴到袋子(zi)(zi)里(li)(li)(li)(li)進(jin)行充(chong)(chong)(chong)氣，但(dan)(dan)是如(ru)果你的產品(pin)是粉末狀(zhuang)的就(jiu)不能(neng)(neng)用起初一(yi)(yi)種(zhong)(zhong)方(fang)法(fa)了，需要(yao)(yao)(yao)第二(er)種(zhong)(zhong)在真空室(shi)充(chong)(chong)(chong)氣利用壓力差(cha)充(chong)(chong)(chong)滿(man)袋子(zi)(zi)。可是客(ke)戶(hu)又要(yao)(yao)(yao)要(yao)(yao)(yao)求(qiu)達到一(yi)(yi)定比(bi)例(li)的殘氧量(liang)，這就(jiu)很(hen)矛盾了。
