Have you already ordered TC4? From the seller's website, they're no longer selling finished board for orders received after 30/7! Yet, they still sell kit and you've to do some soldering on some components.

Unless you want the TC4 to standalone and workable as a separate device, otherwise, if you'd monitor the temperature change realtime on screen, you don't need LCD. Even the Kona PID sketch also doesn't need any LCD to run it in the latest version.

I usually drop between the end of 1st crack and begin of 2nd crack (city+ .... FC-). The decision to drop is not base on time, time is only for referecing. Since the roasting level, heat power, bean weight, bean type affect time.

I have seen your posts on HB. Very nice.

So can I say that the roaster ( ie the person who do roasting ) is very important to decide ( from sound, smell, experience, ....) when to drop the beans, whereas previous roast records ( eg charts from Artisan ) are helpful for such decision too?

So this Artisan software cannot yet replace the person to do the roasting?

At this stage, I am still using the Artisan software for data logging and curve drawing. It is no magic, all manual control. Instead of controlling the heating power (ampere), I use the PID set value to controlling MET, but not programming for ramp and soak. The graph is using for analysis which supposes to help to enhance the next roast.

I have a dream, to draw / set the roasting BT curve on computer and let the computer software to roast the bean accordingly, but the best is yet to come.

If you use M3, there's no chance to use artisan to "stop" a roast without modifying the roaster a lot. If you are using hottop, you can customize an event button in artisan to activate the cool down process.

今晚焗三batch豆. 有兩batches用同一方法焗, 可以保留多啲水份去後面一爆, 到落豆溫度達BT=220'C, 但顏色及weight loss只係"City"的水平, 以下係果兩幅圖




到咗下面果batch Kona Maragogype, 因為聽信Hawaii海拔低啲豆密度會低啲, 我特登charge的溫度降到150C去避免scrotching, 結果即刻出唔番同上兩batch一樣的效果, 落豆只係達到215'C, 但顏色同weight loss卻已經深到Full City(唉!!!我唔想咁深, 浪費咗啲好豆), 應該係charge的溫度太低令到drying phase太長, 太乾, 上到高溫時水份已經唔夠, 或者另外maragogype有唔同特性...不過今次3條BT我覺得都造得幾直, 希望啲豆聽日試好飲啦!!!

藉此講一下, Artisan入面中間有三條bar, 就係我做咗咩power/fan/drum的Setting的改動, Power的數字係電流ampere數乘2 (即P10係Max Power, P8係4A, P9係4.5A如此類推), DRUM我只係有兩個調節數(900轉(若再慢, 豆子會不能接觸BT測溫棒), 同MAX轉速兩項), Fan係直接在旋鈕上的數字


Hawaii Kona Maragogype的cupping note:
Aeropress coava disc 008, 1:13 ratio, 89'C撞水入去無再搞勻, 45s infusion, 1'20 按完

咖啡約在凍至50'C開始爆發果香(太熱無乜味), 39'C出Violet floral note, 35'C會聞到peach, 30'C出berry/malt, 28'C再出Apricot/peach的鮮香味, 由brew time後45分鐘降至室溫25'C, 之後繼續搖隻杯繼續出唔同的香味, 上述的香味是當啡降至該溫度時搖杯, 會突然浮出來的香味, 係咁索咗成半個鐘有多人都暈得一陣陣....但好奇怪嗅覺無飽和​的感覺, 繼續聞到好香! 好後悔無買多啲呀 (不過佢成本其實貴過Nekisse)!
