真(zhen)空包(bao)裝機廠的(de)真(zhen)空(kong)包裝機增加充(chong)氣(qi)(qi)(qi)功能(neng)是有兩種(zhong)(zhong)(zhong)方式(shi)，一(yi)種(zhong)(zhong)(zhong)是氣(qi)(qi)(qi)嘴(zui)直接伸到(dao)產品袋(dai)子(zi)里(li)面進(jin)行充(chong)氣(qi)(qi)(qi)的(de)，另一(yi)種(zhong)(zhong)(zhong)是把要(yao)(yao)充(chong)的(de)氣(qi)(qi)(qi)體先充(chong)滿(man)整個真(zhen)空(kong)室(shi)，然后(hou)靠(kao)負壓差充(chong)滿(man)袋(dai)子(zi)。那究竟采用哪種(zhong)(zhong)(zhong)方式(shi)充(chong)氣(qi)(qi)(qi)好(hao)呢，這里(li)主要(yao)(yao)看客戶的(de)產品性質，單純來(lai)說肯(ken)定(ding)(ding)是直接沖到(dao)袋(dai)子(zi)里(li)比較好(hao)，這樣(yang)置換的(de)又(you)(you)純還能(neng)省不少氣(qi)(qi)(qi)源，但是大家一(yi)定(ding)(ding)要(yao)(yao)考慮好(hao)自己產品性質。如(ru)果產品是顆粒，我(wo)們可以采取起(qi)初一(yi)種(zhong)(zhong)(zhong)方法直接讓(rang)充(chong)氣(qi)(qi)(qi)嘴(zui)到(dao)袋(dai)子(zi)里(li)進(jin)行充(chong)氣(qi)(qi)(qi)，但是如(ru)果你的(de)產品是粉(fen)末狀的(de)就不能(neng)用起(qi)初一(yi)種(zhong)(zhong)(zhong)方法了，需要(yao)(yao)第二種(zhong)(zhong)(zhong)在真(zhen)空(kong)室(shi)充(chong)氣(qi)(qi)(qi)利用壓力差充(chong)滿(man)袋(dai)子(zi)。可是客戶又(you)(you)要(yao)(yao)要(yao)(yao)求達到(dao)一(yi)定(ding)(ding)比例的(de)殘氧(yang)量(liang)，這就很矛(mao)盾(dun)了。
