其實一次不會只磨70g,會用75g左右
但每次使用粉量是14±0.1g
錄影部分可能明天才能進行(找的到三腳架的話)
今天晚上要準備明日百懋要來取的樣品

佈粉手法前面有提過,個人做咖啡流程大致如下:
無底(抓數據時)或分流(抓完數據後)把手裝雙份濾杯放上接粉環,量豆下豆,粉杯接粉測粉重
到扣於接粉環上,甩鍋,WDT,取下接粉環,輕敲底部使粉面較平,再次WDT
輕敲把手使粉面較為平整,將填壓器"置放"於咖啡粉上,旋轉填壓器(只靠填壓器本身重量),扣把
新鮮或不新鮮的豆子何者較穩定,這個人就不清楚了
不過個人想法是廠豆是已經完全反應完了
不像是新鮮豆子反應尚未完畢,萃取過程會因二氧化碳所影響
所以個人覺得廠豆比較穩定,個人經驗的部分...
因為廠豆我會以IES方是萃取,台灣自烘豆是以SES方式萃取,故無法比較穩定度
個人用的義大利配方豆製造日期都在一年(唐科爾特斯)或半年(Lavazza)內
對廠豆應該都還算是新鮮啦

殘粉問題,無油式空壓機很好用,哈哈
接著是,原廠對照片的回覆,附錄如下:
Due to the construction design of EK43, the parallel of burrs can only be adjusted manually when you re-assemble the front panel. If customer thought the burrs are not parallel please tight/loose the two screws of front panel in turns until they get a good result. It DOES NOT mean that the front panel will be complete parallel when the two screws are both tightened.
因為EK43機構設計的緣故,刀盤的平行度只有在重新組裝前面板(front panel)時才有可能被調整。如果客戶認為刀盤不平行,請輪流鎖緊或是放鬆前面板的兩顆螺絲,直到其達到客戶滿意的效果為止。但這並不表示前面板的兩顆螺絲鎖緊,刀盤就會完全平行。
We are sure that each grinder come out of the factory is already adjusted completely parallel so there cannot be this kind of issue if nobody dis-assembled the front panel. I understand customer need frequently open the grind chamber for cleaning so please kindly ask them to pay attention to this parallel issue when they close it up.
我們很確定每一台磨豆機出廠時,刀盤都是被調整至完全平行的,所以如果在前面板沒有被拆卸過的情況下,是不可能會有這種狀況發生的。我們了解客戶經常需要打開磨豆室來做清潔動作,所以請提醒他們在組回前面板時,一定要特別注意這個部分。
BTW I have read the complete article on the website and I’m afraid I do not suggest to do this kind of test as it will definitely harm the burrs which will never touch each other during a normal grinding. Also as the comment from Marc Wiebe, this test cannot lead to the result that the burrs are parallel because “the static burr would only have been rubbed off in one area and the rotating burr would have lost all its ink”.
順道一提,我也讀過了網站上的文章。我們並不建議使用那種測試方式,因為這可能會傷害刀盤,在正常使用狀況下刀盤是不會互相摩擦的。同時也如同Marc Wiebe先生所說,這個測試結果無法證明刀盤是否平行,因為"靜止的刀盤可能只會被摩擦到某一部份,而旋轉的刀盤卻可能掉了所有的油墨"
以上
最後Marc Wiebe先生在魚大所貼的連結是出現在回覆
原文茲附如下:
hello,
thanks for the write up.
However can’t you only do this on the static burr? as in the inner bur on the ek 43?
for example if you rotate two coins in the same way coffee burrs rotate, the rotating coin will rub its entire edge against one specific
part of the static coin (assuming the coins are not rotating parallel) So if you go had marked both coins the static coin would only have been rubbed off in one area and the
rotating coin would have lost all its ink .
原廠說burrs但Marc Wiebe先生是說coin,故也搞不清楚是不是同文章。
而Spencer Webb先生也寫出Part.2了
Spencer Webb先生是認為校正平行度是有改善的作用的

另,整本說明書中EK43根本就沒有"前面板(front panel)"這個零件
剛剛特地把說明書拿出來翻,不過推測應該是grinder casing cover(研磨室外蓋?)
弔詭的是,要藉由鎖研磨室外蓋的那兩顆螺絲的鬆緊來調整刀盤平行度
那到底要如何確認刀盤平行?是以肉眼或手指分辨粉末粗細及一致性?
總不能期待家中甚至店家中有粒徑分析裝置吧...
還是要固定刻度後,調整研磨室外蓋的兩顆螺絲鬆緊度做研磨,研磨後沖煮至有穩定數據?
看到原廠回應其實個人有些傻眼...
"如果客戶認為刀盤不平行,請輪流鎖緊或是放鬆前面板的兩顆螺絲,直到其達到客戶滿意的效果為止。"
不建議磨刀盤,也看不見刀盤,個人不太了解如何得到滿意的結果啦...
而且同刻度磨出來的粉出現流不出來跟流速過快的那時
並未拆過機清潔,是上來問問題後,看了Spencer Webb先生的文章後
才拆開做歸零兼測試平行度...
磨樣本去...可惜新買的咖啡豆了
剩下百懋取樣本回去測試
及派人過來檢驗了
明日有時間會拍照片或影片
不過照片比較有可能就是了
