真空包裝機廠的(de)真(zhen)空包裝機增加充(chong)(chong)(chong)氣(qi)(qi)功能(neng)是(shi)(shi)有兩種(zhong)(zhong)方式，一(yi)種(zhong)(zhong)是(shi)(shi)氣(qi)(qi)嘴直(zhi)接伸到(dao)產(chan)品袋子(zi)(zi)里(li)面進行充(chong)(chong)(chong)氣(qi)(qi)的(de)，另(ling)一(yi)種(zhong)(zhong)是(shi)(shi)把要(yao)(yao)充(chong)(chong)(chong)的(de)氣(qi)(qi)體(ti)先充(chong)(chong)(chong)滿(man)整(zheng)個(ge)真(zhen)空室，然后靠(kao)負(fu)壓差充(chong)(chong)(chong)滿(man)袋子(zi)(zi)。那究(jiu)竟采用哪種(zhong)(zhong)方式充(chong)(chong)(chong)氣(qi)(qi)好(hao)(hao)呢，這(zhe)里(li)主要(yao)(yao)看(kan)客(ke)戶的(de)產(chan)品性質，單純來(lai)說肯定(ding)是(shi)(shi)直(zhi)接沖到(dao)袋子(zi)(zi)里(li)比較好(hao)(hao)，這(zhe)樣置換的(de)又(you)純還(huan)能(neng)省不(bu)少氣(qi)(qi)源，但是(shi)(shi)大家(jia)一(yi)定(ding)要(yao)(yao)考慮好(hao)(hao)自(zi)己產(chan)品性質。如果產(chan)品是(shi)(shi)顆粒，我(wo)們可(ke)以采取起初一(yi)種(zhong)(zhong)方法直(zhi)接讓充(chong)(chong)(chong)氣(qi)(qi)嘴到(dao)袋子(zi)(zi)里(li)進行充(chong)(chong)(chong)氣(qi)(qi)，但是(shi)(shi)如果你(ni)的(de)產(chan)品是(shi)(shi)粉末狀的(de)就(jiu)不(bu)能(neng)用起初一(yi)種(zhong)(zhong)方法了，需要(yao)(yao)第(di)二種(zhong)(zhong)在真(zhen)空室充(chong)(chong)(chong)氣(qi)(qi)利用壓力差充(chong)(chong)(chong)滿(man)袋子(zi)(zi)。可(ke)是(shi)(shi)客(ke)戶又(you)要(yao)(yao)要(yao)(yao)求達到(dao)一(yi)定(ding)比例(li)的(de)殘氧(yang)量，這(zhe)就(jiu)很矛盾了。
