真(zhen)空包裝機廠(chang)的(de)(de)真空包裝機增加充(chong)(chong)氣(qi)(qi)(qi)(qi)(qi)(qi)功(gong)能(neng)(neng)是(shi)有兩種(zhong)(zhong)方(fang)式，一種(zhong)(zhong)是(shi)氣(qi)(qi)(qi)(qi)(qi)(qi)嘴(zui)直接(jie)伸到產(chan)品(pin)(pin)袋子里面進(jin)行充(chong)(chong)氣(qi)(qi)(qi)(qi)(qi)(qi)的(de)(de)，另(ling)一種(zhong)(zhong)是(shi)把要(yao)充(chong)(chong)的(de)(de)氣(qi)(qi)(qi)(qi)(qi)(qi)體先(xian)充(chong)(chong)滿(man)(man)整個(ge)真空室(shi)，然后靠(kao)負壓差充(chong)(chong)滿(man)(man)袋子。那究(jiu)竟采用(yong)哪種(zhong)(zhong)方(fang)式充(chong)(chong)氣(qi)(qi)(qi)(qi)(qi)(qi)好呢，這里主要(yao)看客戶的(de)(de)產(chan)品(pin)(pin)性質，單純來說肯定(ding)是(shi)直接(jie)沖(chong)到袋子里比較好，這樣置換的(de)(de)又純還能(neng)(neng)省不少(shao)氣(qi)(qi)(qi)(qi)(qi)(qi)源，但(dan)是(shi)大(da)家一定(ding)要(yao)考慮(lv)好自(zi)己產(chan)品(pin)(pin)性質。如果產(chan)品(pin)(pin)是(shi)顆(ke)粒，我們可以采取起(qi)初一種(zhong)(zhong)方(fang)法直接(jie)讓充(chong)(chong)氣(qi)(qi)(qi)(qi)(qi)(qi)嘴(zui)到袋子里進(jin)行充(chong)(chong)氣(qi)(qi)(qi)(qi)(qi)(qi)，但(dan)是(shi)如果你的(de)(de)產(chan)品(pin)(pin)是(shi)粉末狀的(de)(de)就不能(neng)(neng)用(yong)起(qi)初一種(zhong)(zhong)方(fang)法了，需要(yao)第二種(zhong)(zhong)在真空室(shi)充(chong)(chong)氣(qi)(qi)(qi)(qi)(qi)(qi)利用(yong)壓力差充(chong)(chong)滿(man)(man)袋子。可是(shi)客戶又要(yao)要(yao)求(qiu)達到一定(ding)比例的(de)(de)殘氧量，這就很矛(mao)盾(dun)了。
