真空包裝機廠的真(zhen)空(kong)包(bao)裝機增(zeng)加充(chong)(chong)(chong)氣(qi)功能是(shi)有兩種(zhong)(zhong)方式(shi)，一(yi)種(zhong)(zhong)是(shi)氣(qi)嘴直接伸到(dao)產(chan)(chan)(chan)品袋(dai)子(zi)里面進行(xing)充(chong)(chong)(chong)氣(qi)的，另(ling)一(yi)種(zhong)(zhong)是(shi)把要(yao)充(chong)(chong)(chong)的氣(qi)體(ti)先(xian)充(chong)(chong)(chong)滿(man)(man)整個真(zhen)空(kong)室(shi)，然后靠(kao)負壓(ya)差充(chong)(chong)(chong)滿(man)(man)袋(dai)子(zi)。那(nei)究竟采用哪種(zhong)(zhong)方式(shi)充(chong)(chong)(chong)氣(qi)好(hao)呢，這里主(zhu)要(yao)看客戶(hu)的產(chan)(chan)(chan)品性質(zhi)，單純來說肯定(ding)是(shi)直接沖到(dao)袋(dai)子(zi)里比較(jiao)好(hao)，這樣置(zhi)換的又純還(huan)能省不少氣(qi)源，但(dan)是(shi)大家(jia)一(yi)定(ding)要(yao)考慮(lv)好(hao)自己產(chan)(chan)(chan)品性質(zhi)。如(ru)果產(chan)(chan)(chan)品是(shi)顆粒，我(wo)們可(ke)以采取(qu)起初(chu)一(yi)種(zhong)(zhong)方法直接讓充(chong)(chong)(chong)氣(qi)嘴到(dao)袋(dai)子(zi)里進行(xing)充(chong)(chong)(chong)氣(qi)，但(dan)是(shi)如(ru)果你的產(chan)(chan)(chan)品是(shi)粉末狀的就(jiu)不能用起初(chu)一(yi)種(zhong)(zhong)方法了，需要(yao)第二種(zhong)(zhong)在真(zhen)空(kong)室(shi)充(chong)(chong)(chong)氣(qi)利用壓(ya)力差充(chong)(chong)(chong)滿(man)(man)袋(dai)子(zi)。可(ke)是(shi)客戶(hu)又要(yao)要(yao)求達到(dao)一(yi)定(ding)比例(li)的殘(can)氧量(liang)，這就(jiu)很矛盾了。
