真空包裝機(ji)廠的真(zhen)空(kong)包(bao)裝機(ji)增加充(chong)氣(qi)(qi)功能是(shi)(shi)(shi)有兩種(zhong)(zhong)方式(shi)，一(yi)種(zhong)(zhong)是(shi)(shi)(shi)氣(qi)(qi)嘴直接(jie)伸到(dao)產品(pin)袋(dai)(dai)子(zi)里(li)面(mian)進行(xing)充(chong)氣(qi)(qi)的，另一(yi)種(zhong)(zhong)是(shi)(shi)(shi)把要(yao)(yao)充(chong)的氣(qi)(qi)體(ti)先充(chong)滿(man)整個(ge)真(zhen)空(kong)室，然(ran)后(hou)靠負(fu)壓差充(chong)滿(man)袋(dai)(dai)子(zi)。那究竟采(cai)用(yong)哪種(zhong)(zhong)方式(shi)充(chong)氣(qi)(qi)好(hao)呢，這里(li)主要(yao)(yao)看客戶的產品(pin)性質，單純來說肯定是(shi)(shi)(shi)直接(jie)沖到(dao)袋(dai)(dai)子(zi)里(li)比較好(hao)，這樣置換的又(you)純還能省(sheng)不少氣(qi)(qi)源，但是(shi)(shi)(shi)大家一(yi)定要(yao)(yao)考(kao)慮(lv)好(hao)自己產品(pin)性質。如(ru)果產品(pin)是(shi)(shi)(shi)顆粒(li)，我們可(ke)以采(cai)取(qu)起(qi)(qi)初一(yi)種(zhong)(zhong)方法(fa)直接(jie)讓充(chong)氣(qi)(qi)嘴到(dao)袋(dai)(dai)子(zi)里(li)進行(xing)充(chong)氣(qi)(qi)，但是(shi)(shi)(shi)如(ru)果你的產品(pin)是(shi)(shi)(shi)粉末狀的就不能用(yong)起(qi)(qi)初一(yi)種(zhong)(zhong)方法(fa)了(le)，需要(yao)(yao)第二種(zhong)(zhong)在(zai)真(zhen)空(kong)室充(chong)氣(qi)(qi)利(li)用(yong)壓力差充(chong)滿(man)袋(dai)(dai)子(zi)。可(ke)是(shi)(shi)(shi)客戶又(you)要(yao)(yao)要(yao)(yao)求達到(dao)一(yi)定比例的殘(can)氧量，這就很(hen)矛(mao)盾了(le)。
