I would like to ask if i can freeze or cooling my roasted coffee beans before grind them in order to reduce the high heat in ground coffee .

I use 3 phase grinder ( 140mm ) disc . My grind setting is extra fine ( turkish coffee ) , the coffee temperature when just go out of machine reach (62 c° ) (143F ) especially when grind weight exceed 250 gram .

Is that temperature acceptable ?
Anyone have some issue or solutions , i dont know if i can depend on reducing motor speed ?

Youre trying to cool beans so the heating by the grinding process is less? I don't think freezing the beans will help much. Friction is friction and your burrs are already huge. take breaks and let it cool?

my issue is i want to reduce the heating produced in grinding process . My grinder its commercial grinder with high output power to use is in roastery shop . Its equivalent for ditting grinder.

I hope if anyone know whats the accepted temperature after grinding ?

If one of the reasons we avoid the blade grinders is they heat grind, but much less, under 50 c°, then 62 is definitely too much, even if I can't give an exact answer to OP question.

As a reference, about 55 c° is the point where an average skin feel risk to burn, especially in hot water.
We don't want coffee so hot to not be able to touch, definitely...

My grinder is flat burr disc with large diameter 140mm which is considered good size to avoid heating . But i think the high motor speed contribute in that heating. Now i start freezing my beans to see results . I will post the results if that way its effective .

Frozen beans are more ridged and will fracture differently than room temperature beans, so you need to adjust your grind settings accordingly to compensate.
