Topic: Behmor Door Dance (4 msgs / 65 lines)
1) From: Robert Yoder
Greetings, great group,
 
I think I sense some consensus on using the Behmor door to slow roasts.  Is there a standard "Door-Open" method?  Are we talking crack it open an eighth of an inch?  Are we talking wide open?  Are we talking holding it open some distance for some time?
 
I have mounted an ET thermocouple in the Behmor, but its utility is limited by the Behmor's own circuitry which cycles the heating elements to fight the heat loss caused by opening the door.  (So it's a little like Politics Polka: Two steps forward and two steps back.) My Bean Mass Temperature indicator is only good for about five degree sensitivity, but at least with this I can make sure there is no DROP in BMT caused by opening the door.
 
Any thoughts on standards and practices for the Door Dance?
 
Happy Roasting,

I just leave the door alone.  You  can change the response of the beans 
by changing the weight of the charge.

I haven't really experimented. If 1st crack seems to be fast, I hold ther
door open 1/4" - 1/2" until it slows down. Sometimes that's pretty much all
the way through 1st crack. Most of the time I'm looking for a C+ roast, so
using miKe's 3 to 3-1/2 minute rule, I need to stretch the crack out a bit.

It's just not worth chewing through the leather straps

What I found works best for me is about 5 seconds into 1st crack, I fully
open the door for about 30 seconds, and then hold it open about 1/4 to 1/2
inch until my desired roast length (just at the beginning of 2nd crack
usually).  This gets me about 3.5 - 4 minutes from 1st crack to end of
roast.
