Behmor 1600 Plus - Coffee Roaster

[cafelazio]

Thanks Whatever. Was wondering what times do you or others have for larger batches. I don't think i'm baking? ...Opinions?...
I've done 20 or so batches at 450 grams and usually get around 385-390 grams. First crack at around 13:30 min - 15 min and remove when f.c. it ends. Roast times total 15 to 17 minutes depending on bean and f.c. I am yet to roast when its cooler. Ambient temps have been mid 20's C. I roast in manual and found a base profile that seems to work. I like the roast to appear dry with some texture still on the bean am guessing CS7 or CS8 and perhaps some spots of oil after week on some beans. I cut beans in half to check development or inner scorching. The roasts taste very nice. I might add i started roasting in December,a few months now, and nearly all I've learnt is from CoffeeSnobs.com.au so THANKYOU ALL. aldo.

Have done up to 500g for something I want to roast very light. But I find at 500g the roast starts to bake more than roast, so the end result isn't as nice.

Any Behmor Plus users regularly roasting 500 gram batches ? What is the maximum charge weight the Behmor will roast well ?
Thankyou CS's.
aldo.

Or you put the thermocouple plugs in the wrong spots....

Yes, that would do it

Is that the one I just installed?

Yes:

Error Code 5

Loose connection on the DC fan?

Damn just attempted my first roast and I'm getting error 5 after a few minutes. After burner is glowing and both the side fan and triangle fan are running from start to when it shuts down.... Any suggestions please?

Yeah I was thinking maybe it was extraction fan.

There's a fan at the top of the roaster directly behind the display panel that blows air out of the roaster. There's also a big cool air fan at the back of the roaster.

Presumably the fan is designed to bring cooler air into the machine from the surrounding atmosphere, and direct it toward the main board etc. Wouldn't be a lot of point otherwise?

[Makka65]

Yep, it's not actually a requirement but in very hot climates it helps get a little more air across the circuit board and then out the exhaust via the other fan in the triangle housing.
If you sucked air out you would fight the other fan.

The first few builds of the Behmor didn't have the side fan but did have the provision on the circuit board. You do need the triangle fan but the side fan is just added flow.

Sounds logical and definite plus in Darwin!

PCB and new fan installed! Just checking if this is the right way for the fan to be installed. This is the way the old one was an it blows air into the machine.
