Hey hey : )
Over the last 2 years Ive made some interesting observations with my oven roasting, Ill go through it all because... it means Ill (sadly) have to give up roasting in the oven.
Okay, I use a sharp convection oven, not sure what model number or anything but its the biggest size, and they make fffffffffantastic ovens. I absolutely love it, and it does a great job with coffee too.
2 years ago, my oven started to make this horrible noise when we turned the oven on.. over a few weeks it got worse and worse until the fan that blows the heat from the elements stopped working.
Id been roasting coffee in the oven for around a year. At the time I didnt really think it was related though.
The oven was a month out of the 5 year warranty, and being absolutely hopeless with anything mechanical/electrical, I bought a new one. This time I was too tight to buy the 5 year warranty.
So, Ive had oven number 2 for a year now. FOUR DAYS before the 12 month warranty expired, the exact same thing happened - the noises, and the fan failure which renders the oven useless.
With the warranty it got fixed in a couple of hours luckily, and the electrician told me that the ball bearings and shaft were "stuffed". Thats all the details I could get out of him :-?
I think now, that its a bit obvious.... the smoke?, oils?, and possibly the chaff from roasting coffee in the oven has covered the moving parts with a grit that stopped them working properly and/or broke them. ... thats my theory anyway? It took both ovens around 12 months to fail, roasting 1-2 roasts per week.
I had a look at the exhaust vents on the back of the oven too, and they have quite a bit of dark brown grit on them.
Would yas agree that the coffee roasting is responsible?
I wonder what Ill do for a roaster now.. haha.
