真空(kong)包裝機廠的真空(kong)包裝機增加充(chong)(chong)氣(qi)(qi)功(gong)能是(shi)(shi)(shi)(shi)(shi)有兩種(zhong)(zhong)方(fang)(fang)式(shi)，一種(zhong)(zhong)是(shi)(shi)(shi)(shi)(shi)氣(qi)(qi)嘴直接(jie)伸到(dao)產(chan)品(pin)(pin)袋(dai)(dai)子(zi)(zi)(zi)里(li)(li)面(mian)進(jin)行充(chong)(chong)氣(qi)(qi)的，另一種(zhong)(zhong)是(shi)(shi)(shi)(shi)(shi)把要(yao)充(chong)(chong)的氣(qi)(qi)體(ti)先充(chong)(chong)滿(man)整(zheng)個真空(kong)室，然后靠負壓(ya)差充(chong)(chong)滿(man)袋(dai)(dai)子(zi)(zi)(zi)。那究(jiu)竟采用(yong)哪種(zhong)(zhong)方(fang)(fang)式(shi)充(chong)(chong)氣(qi)(qi)好(hao)(hao)呢，這里(li)(li)主要(yao)看客(ke)戶的產(chan)品(pin)(pin)性質，單純來說(shuo)肯定是(shi)(shi)(shi)(shi)(shi)直接(jie)沖到(dao)袋(dai)(dai)子(zi)(zi)(zi)里(li)(li)比較好(hao)(hao)，這樣置換的又純還能省不(bu)少(shao)氣(qi)(qi)源，但(dan)是(shi)(shi)(shi)(shi)(shi)大家一定要(yao)考慮好(hao)(hao)自己產(chan)品(pin)(pin)性質。如果產(chan)品(pin)(pin)是(shi)(shi)(shi)(shi)(shi)顆(ke)粒，我(wo)們可(ke)以采取起初一種(zhong)(zhong)方(fang)(fang)法直接(jie)讓充(chong)(chong)氣(qi)(qi)嘴到(dao)袋(dai)(dai)子(zi)(zi)(zi)里(li)(li)進(jin)行充(chong)(chong)氣(qi)(qi)，但(dan)是(shi)(shi)(shi)(shi)(shi)如果你(ni)的產(chan)品(pin)(pin)是(shi)(shi)(shi)(shi)(shi)粉末狀的就不(bu)能用(yong)起初一種(zhong)(zhong)方(fang)(fang)法了，需(xu)要(yao)第二種(zhong)(zhong)在(zai)真空(kong)室充(chong)(chong)氣(qi)(qi)利用(yong)壓(ya)力差充(chong)(chong)滿(man)袋(dai)(dai)子(zi)(zi)(zi)。可(ke)是(shi)(shi)(shi)(shi)(shi)客(ke)戶又要(yao)要(yao)求達到(dao)一定比例的殘(can)氧量，這就很(hen)矛盾了。
