主因應該是底部出水孔是圓形,沒有導水條或延伸到底部的肋骨條,導致濾紙與出水孔是緊密貼合,沒有空氣對流幫助排水,以致流速變慢。
最明顯的例子可參考一般v60跟粕谷哲設計的v60,差別就在粕谷哲設計的下方出水孔完全沒有任何導水線或肋骨延伸至底部當導水線,因此粕谷哲的出水孔是一個完整的圓形,不想一般v60呈鋸齒狀。且粕谷哲用意就是要流速慢、要浸泡效果。
原po底下推文有版友說是沒有肋骨的關係,我認為關係不大,粕谷哲的v60有側邊肋條,但流速仍然是公認的慢。
另一個例子是kono的短肋濾杯,大家可能會以為短肋應該流速慢,但實際用起來往往會嚇一跳。無肋條高水位的部分或許流速略慢,但也不是慢到非常有感,整體流速仍是偏快,這是有實測的結果。
有興趣的朋友不妨借或買來試試看。
對了,m01有人買了粕谷哲版的V60嫌太慢,之後把濾紙折一下,讓濾紙跟底部出水孔接觸面積
減少到只接觸2/3,感覺流速有比較順暢,原po不妨試試。
※ 引述《rockguitar (Heavy Metal~!!)》之銘言:
: 平常在家都是用Hario V60濾杯
: 在公司為了方便買了Driver的摺疊濾杯
: https://www.cy-driver.com.tw/driver/HM-ZDV60-A1.html/
: 一樣用V60的濾紙
: 同樣的粉量.研磨度.水量
: 為什麼摺疊濾杯的流速慢非常多呢?
: 感覺摺疊濾杯只是把濾紙撐著
: 應該流速會比V60快啊
: 反而萃取到後段感覺好像塞住流很慢
