真空包裝機廠的真(zhen)空包裝機增(zeng)加充(chong)(chong)氣(qi)(qi)功能(neng)是(shi)有(you)兩種(zhong)方(fang)式，一(yi)種(zhong)是(shi)氣(qi)(qi)嘴直接伸(shen)到產(chan)(chan)品袋子(zi)里面進行充(chong)(chong)氣(qi)(qi)的，另一(yi)種(zhong)是(shi)把(ba)要充(chong)(chong)的氣(qi)(qi)體先充(chong)(chong)滿(man)整(zheng)個真(zhen)空室，然后靠負壓(ya)差充(chong)(chong)滿(man)袋子(zi)。那究竟采用哪(na)種(zhong)方(fang)式充(chong)(chong)氣(qi)(qi)好(hao)呢，這里主要看客戶的產(chan)(chan)品性質，單純(chun)來說肯定是(shi)直接沖到袋子(zi)里比較好(hao)，這樣(yang)置換的又(you)純(chun)還能(neng)省不(bu)少氣(qi)(qi)源，但(dan)是(shi)大家一(yi)定要考慮好(hao)自己產(chan)(chan)品性質。如果(guo)產(chan)(chan)品是(shi)顆粒，我們可(ke)以采取(qu)起初一(yi)種(zhong)方(fang)法直接讓充(chong)(chong)氣(qi)(qi)嘴到袋子(zi)里進行充(chong)(chong)氣(qi)(qi)，但(dan)是(shi)如果(guo)你的產(chan)(chan)品是(shi)粉末狀的就不(bu)能(neng)用起初一(yi)種(zhong)方(fang)法了，需(xu)要第二(er)種(zhong)在真(zhen)空室充(chong)(chong)氣(qi)(qi)利(li)用壓(ya)力(li)差充(chong)(chong)滿(man)袋子(zi)。可(ke)是(shi)客戶又(you)要要求達到一(yi)定比例的殘氧量，這就很矛盾了。
