電子秤,沒人討論過吧 :P
器材這標題,好像是侷限在'烘/煮豆子的器材'
那溫度計,瓦斯爐,電子秤是器材或其他?

(故事很長)
N天前,想測試一下磨豆機磨最細粉的功力
磨完之後一看,天..豆粉怎麼這麼少
(我是以舀入相同份量的原豆來比較的)
但最後清磨豆機時發現卡了很多殘粉
因此有兩個可能:
1.粗磨時豆粉間的空隙大,總體積也會較大
細磨時豆粉間空隙小,總體積也小(小到沒剩下一半咧)
當時我很懷疑這麼少的粉還能沖咖啡嗎?
2.細磨時的粉更容易卡在粉槽中,所以我得到的淨粉量更少了
公式也許是
Output=Input*Rate-Lost (出豆=入豆*體積變率-殘粉)
也許是
Oupt=(Input-Lost)*Rate
就看卡的殘粉是原豆的定值,或者先變化體積後再卡住定值
(以上公式說的都是體積,所以用體積變率)
我想是前者才對
舉例來說
粗磨:兩匙*0.7-0.5=0.9匙
細磨:兩匙*0.5-0.5=0.5匙
喔,超X,我得到的豆粉真的太少了啦~
當時也有想,如果卡住的殘粉是定值,那我只要再磨一次粉
第二次就不會有損失了,應該可以得到較多豆粉
(舊粉會被擠出來呀,我不會損失的)
兩匙*0.5=1匙
可是沒勇氣了..畢竟我是用塞風,太細的粉會塞住
本次細磨實驗中的豆粉其實都會作癈
另一個原因是
每次買回的豆子,我覺得消耗好快,沖沒幾次
(我買豆子倒沒很快,因為不是天天有煮)
以我習慣兩匙而言,半磅好像沒用到十次
半磅沒二十匙?
而我又習慣買半磅三百的咖啡,除以十..
每杯在豆子的成本就三十元了
板上說自己沖便宜的,大概不像我喝得重口味? ~^_^~
以前不秤豆子的原因,是因為我是舌尖派的
只要覺得味道太淡,下次就放多一點
覺得太濃,下次就放少一點
就好像煮菜會有食譜,但煮久了不會還依賴食譜
結果咧,愈喝愈重,從一杯兩匙,現在還是一杯兩匙
只是以前是淺淺的兩匙,現在是飽滿的兩匙了 ~^_^~
所以我要有個標準,想要秤重
這秤重不是為了口味的穩定,而是為了口袋的穩定 :P
---
在一開始投資咖啡器材時,就曾大概看過小秤子
我家有兩公斤小秤,也有天平
但有一次去喝茶,才看到最可愛實用的
那是電子秤,可歸零
(這樣就不必費心的先計粉匙的空重,還自己做算數)
還有,它的大小,像一台電子計算機
或者說,較厚的名片
因此在攜帶上非常方便
(我不希望買得像超市裏結算水果那台那麼大呀~)
不知有沒有人看過這種東西
不過呢,太小的機子因為機械彈性的問題,只怕靈敏度不高
所以用過的經驗非常重要
嗯..我還繼續在逛奇摩拍賣..
