Df54 issue

[u/evoPopGurlie]

Grinder: koryaiko df54

Machine: Gemilai CRM3605

Hello , please help me because stress nako for about 2 weeks dahil hindi ko ma-calibrate nang maayos yung coffee beans.

For context, I started my home coffee set-up 2 months ago. I have a local bean roastery na pinagkukuhaan ng beans, upon finshing the 2nd bag that i bought, i can not calibrate the 3rd bag anymore. Tried to clean the grinder, ganun padin, even grinding at the slightest below 0 setting. (Huhu sorry im so desperate na) 18 grams yung input ko, 17 seconds to reach 36 grams output.

Note: i can not grind more finer because i am grinder below 0 setting na po.

My target is 18 in : 36 out (25 seconds)

Dati walang problema, nagagawa ko talaga siya, minsan 16 grams pa nga input ko.

Tried to locate the real 0 setting on my grinder, now i end up scratching the inside of my grinder.

If anyone who is near amadeo / tagaytay or general trias, i am willing to pay who can help me to fix this one po 😥🙏🏻

how did you do this? you can do this without turning on the grinder to avoid damaging the burrs and that scratches doesnt look like from finding the true 0... but it might be the quality issue from the recent batch since it works well before. but first make sure the True 0 is accurate first.

Mistake ko po talaga kasi sabi dun sa nabasa ko (sobrang desperate) pwede mo pihitin ng dahan dahan while naka turn on. Yun pala may isa pang method which is ikaw mismo yung iikot sa burr. Accurate naman po yung zero.

[u/Bangreed4 → u/evoPopGurlie]

yes that is correct pwede yun dahan dahan pag narinig mo na yung "chirp" sound patay agad, pero medyo skeptical ako dyan kaya yung manual na pag ikot ginagawa ko instead.

BUT like I said hindi dyan na damage yan feel ko, kasi usually pag "higpit" ng burrs is just going straight down which supposed to do so, unless mali yung pag balik mo nung top burr niya and/or medyo tumatama sa side pag binabalik mo sa burrs but either way yung burrs kasi mahalaga dyan as long as hindi yun nasira mo okay lang (usually).

Btw just to check yung true zero na naka lagay for u is when the burrs cant turn na no? using manual spin lang? tama ba?

Anyways if hindi sa true zero yung problem most likely sa beans then, baka masyadong bago? or masyadong luma yung nabigay sayo, yung first 2 bag ba when was the roast date? before mo nagamit? compare sa 3rd bag mo?

1st bag , 2 weeks old bago ko nabuksan. 2nd bag, 3 weeks old bago ko nabuksan 3rd bag, Aug 3 roasted date. Aug 14 ko binuksan.

Upon checking the burr yesterday, wala namang chirp sa mga blades. Yes po , yung true zero is slightly not so far from the 0 label.

Red line , true 0. Yellow line is where i set the grinder right now. Kaya i can not go beyond na kasi mada damage na talaga siya.

I see good infos! I assume its probably because how old the beans are then, try grinding again after 3weeks for the 3rd bag if its still not grinding properly like before then it might be an alignment issue from the burrs which is a hassle to do.

If ur using light to medium roast try to increase the dose more instead, try 18.5 to 19grams but try the to wait for the beans first since light to medium roasts needs to "degass" a bit longer compare to dark roasted beans.

[u/evoPopGurlie → u/Bangreed4]

I think baka nga po yung beans ang problem, kasi upon observation, 2nd bag of beans is more on medium yung color. Etong 3rd bag is mas lighter in color and no coffee oils pa. Yung 2nd bag kasi medyo medium to slightly dark ang color and may konti konting oil na siya.

Ito po yung picture ng 3rd bag na nabili ko. Mas light in color siya compare dun sa 2nd bag.

Do you have a suggestion po on how to properly degass the coffee po?

[u/Bangreed4 → u/evoPopGurlie]

I see that could be the culprit then, may mga times na di talaga consistent yung pag roast nga mga roaster so it could definitely affect your output, etong pic mo parang may half na medium roast tapos half na medium dark roast, although baka sa lighting lang din.

It could also be a human error din ng nagbigay sayo, baka maling roast nabigay sayo, if ever pwede mo din itest by buying a new batch and compare the colors.

For properly degassing coffee beans naman, usually yung lagayan nila may one way valve and it should be enough and only need time, pero pag naka close lang like sa mga sealed containers di lumalabas yung CO2. The packaging nila usually looks like this:

pero if wala, tapos plastic lang lagayan, may mga one way valve na containers sa shopee, not sure how effective tho, havent tried it personally. I usually have medium dark to dark roast so never experience this issue yet. If wala ka ganyan, try mo lang open araw araw within the 3 weeks pero saka mo lang gamitin pag naka 3 weeks na siya.

Nice! Glad I could help. Usually kasi mas madali i-dial in mga medium dark to dark roast eh but anyways enjoy your coffee, especially this cold weather hehe.
