Cooldown duration

#3341

Post by Ron in Van »

It seems all the profiles I have tried have a six minute cooldown. Is this something that can be changed? I could not see anything in the profiles details that would affect this.

I was thinking of keeping the fan speed higher longer to cool the beans more quickly so that I could move on to the next batch a little faster. Anyone know how to modify it or of reasons not to do this?

That setting is under profile setting at near bottom.

Ben,
Thanks for the quick reply. I saw those settings but i thought they just adjusted the fan speed at the start of cooldown, and when to lower the speed until the end of cooldown based on the "cooldown lo temperature" setting. In this case that lowered the fan speed from 17,000rpm to 15,000rpm when the bean mass gets to 100C. However I don't see why that would mean all my roasts take the same overall time in cooldown.

Any insights would be appreciated.
Regards,
Ron

End of the day it all PID controlled.

May be you set lower tan 100 for last one there to keep higher speed for longer?
It will cooling down near ambient ( not quite exactly and depends on the temp recoded when you power on your roaster ).
KL shroud have more insight on this logic behind but that lo speed and lo temp will be the one I would try to tweak if want to shorten the duration.
