真空包裝機廠的(de)(de)真(zhen)空包裝機增加充(chong)(chong)氣(qi)功(gong)能(neng)是(shi)(shi)有兩種(zhong)方(fang)式,一(yi)種(zhong)是(shi)(shi)氣(qi)嘴直(zhi)接伸(shen)到產(chan)品(pin)袋子(zi)里(li)面進行充(chong)(chong)氣(qi)的(de)(de),另一(yi)種(zhong)是(shi)(shi)把要充(chong)(chong)的(de)(de)氣(qi)體先充(chong)(chong)滿整個真(zhen)空室,然后靠(kao)負壓(ya)差充(chong)(chong)滿袋子(zi)。那(nei)究竟采用(yong)(yong)哪(na)種(zhong)方(fang)式充(chong)(chong)氣(qi)好呢,這里(li)主要看客(ke)戶(hu)的(de)(de)產(chan)品(pin)性質,單(dan)純來說肯定是(shi)(shi)直(zhi)接沖到袋子(zi)里(li)比較好,這樣(yang)置換的(de)(de)又純還能(neng)省(sheng)不(bu)少氣(qi)源(yuan),但是(shi)(shi)大(da)家一(yi)定要考慮好自己產(chan)品(pin)性質。如果產(chan)品(pin)是(shi)(shi)顆粒,我們可以采取起(qi)初一(yi)種(zhong)方(fang)法(fa)直(zhi)接讓充(chong)(chong)氣(qi)嘴到袋子(zi)里(li)進行充(chong)(chong)氣(qi),但是(shi)(shi)如果你(ni)的(de)(de)產(chan)品(pin)是(shi)(shi)粉末狀的(de)(de)就(jiu)不(bu)能(neng)用(yong)(yong)起(qi)初一(yi)種(zhong)方(fang)法(fa)了,需要第(di)二種(zhong)在真(zhen)空室充(chong)(chong)氣(qi)利用(yong)(yong)壓(ya)力差充(chong)(chong)滿袋子(zi)。可是(shi)(shi)客(ke)戶(hu)又要要求達到一(yi)定比例(li)的(de)(de)殘氧量,這就(jiu)很矛(mao)盾了。
