Loaded 600gm of green today. Preheat on thaw with beans for 5 mins, then full power...
Went to make a sandwich, came back 5 mins later (I wasn't far away don't panic), ate sandwich... peered in... umm they look green still. 12 mins had passed on full power. 1st Crack at 20 mins (I nearly fell asleep waiting!!!!!) That is the slowest roast I've done yet! I got a bit of smoke around 25mins, a few snaps of SC so I pulled it and cooled.
Not very even but they where Ethiopia Gambella Sundried. The blade was struggling a tad now and again, but I did play about with it for my 100gm batch and lowered it slightly because beans where being missed by it completely. Doubt that was the issue because the beans where moving well.
My KKTO has never been very good at batches over 500gm (others can do 800gms no worries), the previous good big batches I removed the element guard (but nearly set fire to a towel when removing the TO so I put it back on). Do you think my TO is just under powered? It is a Tiffany model bought with the KKTO. I noticed TOs in the shops have 1200 -1400 watts on them. Maybe I just got a Friday one!? Also when I did use a temperature probe I would always get fluctuations in the temp when the element was kicking on and off, even when I was roasting 500gm and the probe was burried in beans. That's why I gave up with it and sold it. Maybe that points to a problem?
I'm seriously considering a new TO, just to see if that fixes my problems roasting bigger batches. If so does anyone have any recommendations regarding brand and the heating element type? I know that Gra bought a new one but found his old one had a better power output which is kinda why I'm asking.
I really want to get bigger batches going now for the espresso side of things because I have a few neighbours asking for fresh roasted. They really need to be converted from supermarket beans
