真空包裝機廠的(de)(de)真空包裝(zhuang)機增加充(chong)(chong)(chong)氣(qi)功能(neng)是(shi)(shi)有(you)兩種(zhong)方(fang)式(shi)，一種(zhong)是(shi)(shi)氣(qi)嘴直(zhi)接(jie)(jie)伸(shen)到產(chan)(chan)品(pin)袋子里面進(jin)行充(chong)(chong)(chong)氣(qi)的(de)(de)，另一種(zhong)是(shi)(shi)把(ba)要充(chong)(chong)(chong)的(de)(de)氣(qi)體先充(chong)(chong)(chong)滿(man)整個(ge)真空室，然后靠負壓(ya)差充(chong)(chong)(chong)滿(man)袋子。那究竟采用(yong)哪種(zhong)方(fang)式(shi)充(chong)(chong)(chong)氣(qi)好(hao)(hao)呢，這(zhe)里主要看(kan)客戶的(de)(de)產(chan)(chan)品(pin)性質，單純來說肯(ken)定(ding)(ding)是(shi)(shi)直(zhi)接(jie)(jie)沖(chong)到袋子里比較好(hao)(hao)，這(zhe)樣置換的(de)(de)又(you)純還能(neng)省不少氣(qi)源(yuan)，但(dan)是(shi)(shi)大(da)家一定(ding)(ding)要考慮好(hao)(hao)自己產(chan)(chan)品(pin)性質。如(ru)(ru)果產(chan)(chan)品(pin)是(shi)(shi)顆粒，我們可(ke)以(yi)采取(qu)起初(chu)一種(zhong)方(fang)法直(zhi)接(jie)(jie)讓充(chong)(chong)(chong)氣(qi)嘴到袋子里進(jin)行充(chong)(chong)(chong)氣(qi)，但(dan)是(shi)(shi)如(ru)(ru)果你的(de)(de)產(chan)(chan)品(pin)是(shi)(shi)粉末狀的(de)(de)就不能(neng)用(yong)起初(chu)一種(zhong)方(fang)法了(le)，需要第(di)二種(zhong)在真空室充(chong)(chong)(chong)氣(qi)利用(yong)壓(ya)力(li)差充(chong)(chong)(chong)滿(man)袋子。可(ke)是(shi)(shi)客戶又(you)要要求達(da)到一定(ding)(ding)比例的(de)(de)殘(can)氧(yang)量(liang)，這(zhe)就很矛盾了(le)。
