※ 引述《turtlewang (色龜)》之銘言:
: 小弟有一事不明
: 想請教各位大大
: 就是這個標題--
: "密封罐+透氣閥的目的??"
: 就小弟認知
: 密封罐不就是要密封嗎?
: 那+透氣閥的目的是??
: (非戰文)
豆子烘好之後會一直產生氣體 , 也就是所謂的排氣
但是一般的袋子沒排氣孔 , 所以常常會讓豆子悶住 , 沒辦法發展
所以才會有所謂的單向排氣閥透氣袋 , 可排氣 , 又不讓濕氣進去袋子
這樣豆子保存可以比較久
此外像是義式機用的豆子 , 一般來說都需要養豆
很多養完豆都要進冷凍庫保存 (分批使用)
所以等到需要拿出來使用退冰的時候 ,
單向排氣閥也可以避免豆子受潮
密封罐+透氣閥 剛好算是這樣的應用版
通常都是用來保存醬菜或是醃漬物品
((因為會發酵產生氣體))
但是他可以透光....這樣對豆子保存比較負面一點...
光線也是會加速咖啡豆老化的...
不過倒是可以試試看用鋁箔在裡面鋪一層 XD
