真(zhen)空包裝機(ji)廠的真空(kong)包裝機增(zeng)加充(chong)(chong)氣(qi)功能是(shi)有兩種(zhong)(zhong)方式，一(yi)(yi)種(zhong)(zhong)是(shi)氣(qi)嘴直接伸到(dao)產品(pin)袋子(zi)里(li)面進行充(chong)(chong)氣(qi)的，另一(yi)(yi)種(zhong)(zhong)是(shi)把要(yao)充(chong)(chong)的氣(qi)體先充(chong)(chong)滿整個真空(kong)室(shi)，然(ran)后靠負壓差充(chong)(chong)滿袋子(zi)。那究(jiu)竟(jing)采用哪種(zhong)(zhong)方式充(chong)(chong)氣(qi)好呢，這里(li)主(zhu)要(yao)看客戶(hu)的產品(pin)性(xing)質(zhi)，單(dan)純來說(shuo)肯定(ding)是(shi)直接沖到(dao)袋子(zi)里(li)比較好，這樣置換(huan)的又純還能省不少(shao)氣(qi)源，但是(shi)大家一(yi)(yi)定(ding)要(yao)考(kao)慮(lv)好自己產品(pin)性(xing)質(zhi)。如(ru)果產品(pin)是(shi)顆粒(li)，我們可(ke)以采取(qu)起(qi)初(chu)一(yi)(yi)種(zhong)(zhong)方法直接讓充(chong)(chong)氣(qi)嘴到(dao)袋子(zi)里(li)進行充(chong)(chong)氣(qi)，但是(shi)如(ru)果你的產品(pin)是(shi)粉末狀(zhuang)的就不能用起(qi)初(chu)一(yi)(yi)種(zhong)(zhong)方法了，需(xu)要(yao)第二種(zhong)(zhong)在真空(kong)室(shi)充(chong)(chong)氣(qi)利用壓力(li)差充(chong)(chong)滿袋子(zi)。可(ke)是(shi)客戶(hu)又要(yao)要(yao)求達到(dao)一(yi)(yi)定(ding)比例的殘(can)氧量，這就很(hen)矛盾了。
