真(zhen)空包裝機廠的(de)真空(kong)包裝機增加(jia)充(chong)(chong)(chong)氣(qi)(qi)功能(neng)是(shi)有兩(liang)種(zhong)方式，一(yi)種(zhong)是(shi)氣(qi)(qi)嘴(zui)直接伸到產品(pin)(pin)袋(dai)(dai)子(zi)(zi)里(li)面進行(xing)充(chong)(chong)(chong)氣(qi)(qi)的(de)，另一(yi)種(zhong)是(shi)把要(yao)(yao)充(chong)(chong)(chong)的(de)氣(qi)(qi)體先充(chong)(chong)(chong)滿(man)整個(ge)真空(kong)室，然后靠(kao)負壓(ya)差充(chong)(chong)(chong)滿(man)袋(dai)(dai)子(zi)(zi)。那究竟采(cai)用(yong)哪種(zhong)方式充(chong)(chong)(chong)氣(qi)(qi)好呢(ni)，這(zhe)里(li)主要(yao)(yao)看客戶(hu)的(de)產品(pin)(pin)性質，單純(chun)(chun)來說肯定(ding)是(shi)直接沖到袋(dai)(dai)子(zi)(zi)里(li)比較好，這(zhe)樣置換的(de)又純(chun)(chun)還能(neng)省不少氣(qi)(qi)源，但是(shi)大家一(yi)定(ding)要(yao)(yao)考慮(lv)好自己產品(pin)(pin)性質。如(ru)果產品(pin)(pin)是(shi)顆(ke)粒，我們可(ke)(ke)以(yi)采(cai)取起初(chu)一(yi)種(zhong)方法(fa)直接讓充(chong)(chong)(chong)氣(qi)(qi)嘴(zui)到袋(dai)(dai)子(zi)(zi)里(li)進行(xing)充(chong)(chong)(chong)氣(qi)(qi)，但是(shi)如(ru)果你(ni)的(de)產品(pin)(pin)是(shi)粉末(mo)狀的(de)就(jiu)不能(neng)用(yong)起初(chu)一(yi)種(zhong)方法(fa)了，需要(yao)(yao)第二種(zhong)在真空(kong)室充(chong)(chong)(chong)氣(qi)(qi)利用(yong)壓(ya)力(li)差充(chong)(chong)(chong)滿(man)袋(dai)(dai)子(zi)(zi)。可(ke)(ke)是(shi)客戶(hu)又要(yao)(yao)要(yao)(yao)求達(da)到一(yi)定(ding)比例的(de)殘氧量，這(zhe)就(jiu)很矛盾了。
