Posted Fri Jun 29, 2012, 1:23pm Subject: Mazzer Mini on a transformer
I am a US Resident currently living in Europe. I want to get a nice grinder since right now I buying pre espresso ground coffee and would like to grind per dose. As I was about to make my purchase it occurred to me that using a Mazzer Mini speced for a the US 110v and 60hz, might not work well or worse yet, die on running it through a transformer since the transformer can not change the HZ, just the voltage.
So the question is, what will the effects be on the Mazzer? Will it drastically reduce the life of the grinder? Has any one done it?
I emailed Mazzer and have not heard anything back.
Exactly Wayne, The way I always figured it was the reciprocal of the numbers (Hz) 50 divided by 60 = 83.3% 100 - 83.3% = 16.7% faster rpm, or going from 60 to 50 Hz., 16.7% slower rpm. So 1,600 rpm - 267 = 1,333 rpm., a good thing. This would generate less heat to the beans during grinding & therefore less bean aromatic loss (more volatile aromatic retension in the beans) due to the increased frictional heat with an increased rpm.
