真空包裝機廠的(de)(de)(de)真(zhen)空包裝(zhuang)機(ji)增(zeng)加充(chong)(chong)(chong)(chong)氣功能(neng)是(shi)(shi)有兩種方(fang)式，一(yi)(yi)種是(shi)(shi)氣嘴直(zhi)接伸到產(chan)(chan)品(pin)袋(dai)子(zi)里(li)面進行(xing)(xing)充(chong)(chong)(chong)(chong)氣的(de)(de)(de)，另一(yi)(yi)種是(shi)(shi)把要充(chong)(chong)(chong)(chong)的(de)(de)(de)氣體先充(chong)(chong)(chong)(chong)滿整個真(zhen)空室，然后靠負壓差(cha)充(chong)(chong)(chong)(chong)滿袋(dai)子(zi)。那究竟采用哪種方(fang)式充(chong)(chong)(chong)(chong)氣好(hao)呢(ni)，這里(li)主要看(kan)客戶的(de)(de)(de)產(chan)(chan)品(pin)性質，單(dan)純來(lai)說肯定是(shi)(shi)直(zhi)接沖到袋(dai)子(zi)里(li)比較好(hao)，這樣置換的(de)(de)(de)又(you)(you)純還能(neng)省不少(shao)氣源，但是(shi)(shi)大家(jia)一(yi)(yi)定要考慮好(hao)自己產(chan)(chan)品(pin)性質。如果產(chan)(chan)品(pin)是(shi)(shi)顆粒，我們可以采取起初一(yi)(yi)種方(fang)法(fa)直(zhi)接讓充(chong)(chong)(chong)(chong)氣嘴到袋(dai)子(zi)里(li)進行(xing)(xing)充(chong)(chong)(chong)(chong)氣，但是(shi)(shi)如果你的(de)(de)(de)產(chan)(chan)品(pin)是(shi)(shi)粉(fen)末(mo)狀(zhuang)的(de)(de)(de)就不能(neng)用起初一(yi)(yi)種方(fang)法(fa)了，需要第二(er)種在真(zhen)空室充(chong)(chong)(chong)(chong)氣利用壓力差(cha)充(chong)(chong)(chong)(chong)滿袋(dai)子(zi)。可是(shi)(shi)客戶又(you)(you)要要求(qiu)達到一(yi)(yi)定比例(li)的(de)(de)(de)殘氧量(liang)，這就很矛盾了。
