真空包(bao)裝機(ji)廠(chang)的真(zhen)空包(bao)裝機增(zeng)加(jia)充(chong)(chong)(chong)氣(qi)功能(neng)是(shi)(shi)有兩種(zhong)(zhong)(zhong)(zhong)方式(shi)，一(yi)種(zhong)(zhong)(zhong)(zhong)是(shi)(shi)氣(qi)嘴直接(jie)伸(shen)到(dao)產(chan)品(pin)袋子里(li)面(mian)進(jin)行(xing)(xing)充(chong)(chong)(chong)氣(qi)的，另一(yi)種(zhong)(zhong)(zhong)(zhong)是(shi)(shi)把要充(chong)(chong)(chong)的氣(qi)體先充(chong)(chong)(chong)滿(man)整個真(zhen)空室(shi)，然后靠負壓差(cha)充(chong)(chong)(chong)滿(man)袋子。那究竟采(cai)用(yong)哪(na)種(zhong)(zhong)(zhong)(zhong)方式(shi)充(chong)(chong)(chong)氣(qi)好(hao)呢(ni)，這里(li)主(zhu)要看客戶的產(chan)品(pin)性質，單純來(lai)說肯定(ding)是(shi)(shi)直接(jie)沖到(dao)袋子里(li)比較好(hao)，這樣(yang)置換的又純還能(neng)省不(bu)少(shao)氣(qi)源，但(dan)(dan)是(shi)(shi)大(da)家(jia)一(yi)定(ding)要考(kao)慮好(hao)自己產(chan)品(pin)性質。如果產(chan)品(pin)是(shi)(shi)顆(ke)粒，我們(men)可以采(cai)取(qu)起(qi)初(chu)一(yi)種(zhong)(zhong)(zhong)(zhong)方法直接(jie)讓充(chong)(chong)(chong)氣(qi)嘴到(dao)袋子里(li)進(jin)行(xing)(xing)充(chong)(chong)(chong)氣(qi)，但(dan)(dan)是(shi)(shi)如果你的產(chan)品(pin)是(shi)(shi)粉末狀的就不(bu)能(neng)用(yong)起(qi)初(chu)一(yi)種(zhong)(zhong)(zhong)(zhong)方法了，需要第二種(zhong)(zhong)(zhong)(zhong)在真(zhen)空室(shi)充(chong)(chong)(chong)氣(qi)利用(yong)壓力(li)差(cha)充(chong)(chong)(chong)滿(man)袋子。可是(shi)(shi)客戶又要要求達到(dao)一(yi)定(ding)比例的殘氧量，這就很(hen)矛盾(dun)了。
