真空包(bao)裝機廠的真空包裝(zhuang)機增(zeng)加充(chong)氣功能是(shi)有兩種(zhong)(zhong)(zhong)方(fang)(fang)式,一種(zhong)(zhong)(zhong)是(shi)氣嘴(zui)直接(jie)伸到產(chan)品(pin)袋(dai)子里(li)面進行(xing)充(chong)氣的,另一種(zhong)(zhong)(zhong)是(shi)把要(yao)充(chong)的氣體先(xian)充(chong)滿整個真空室(shi),然后靠負壓差(cha)充(chong)滿袋(dai)子。那究竟采用哪(na)種(zhong)(zhong)(zhong)方(fang)(fang)式充(chong)氣好呢,這里(li)主要(yao)看客(ke)戶的產(chan)品(pin)性(xing)質,單純來說肯定(ding)是(shi)直接(jie)沖(chong)到袋(dai)子里(li)比較(jiao)好,這樣置換的又純還能省不少(shao)氣源,但是(shi)大家一定(ding)要(yao)考慮好自己產(chan)品(pin)性(xing)質。如果產(chan)品(pin)是(shi)顆粒,我們(men)可(ke)以(yi)采取起(qi)初(chu)一種(zhong)(zhong)(zhong)方(fang)(fang)法直接(jie)讓充(chong)氣嘴(zui)到袋(dai)子里(li)進行(xing)充(chong)氣,但是(shi)如果你的產(chan)品(pin)是(shi)粉末狀的就不能用起(qi)初(chu)一種(zhong)(zhong)(zhong)方(fang)(fang)法了(le),需要(yao)第二種(zhong)(zhong)(zhong)在真空室(shi)充(chong)氣利用壓力差(cha)充(chong)滿袋(dai)子。可(ke)是(shi)客(ke)戶又要(yao)要(yao)求達到一定(ding)比例的殘氧量,這就很矛盾(dun)了(le)。
