Topic: help; fast roast times with popper (3 msgs / 51 lines)
1) From: Deerslammer
i'm new to roasting and am roasting with a wearever popcorn pumper 1400  
watts. i'm roasting as much as the hopper will hold at a "dance" of beans at the  
beginning. i'm guessing 1 cup. i'm starting first crack aroung 3 minutes  and 
finishing at about 5-6 min. lots of smoke. at the end of the roast my  non 
contact lazer thermometer is reading upwards of 490 degrees. my roasts seem  
uniform and taste good to me but it seems as if the roast should take longer. am  
i doing ok or could my coffee be much better with slowing down the roast? i 
have  a dimmer on the fan and can slow down the air. how might i slow the roast 
if  needed.
    thanks in advance
          dave in  pa.

If you want to slow the roast down, put in *fewer* beans, not more
beans.  A lighter load will make it take longer, which is
counter-intuitive at first, but it's because a larger load reduces air
flow, less air moving past the heating elements means the elements get
hotter, and the air gets hotter, so hotter air blows on your beans.
Then that hotter, slower air transfers more heat to the beans because
it's not only hotter but stays in contact with the beans longer before
exiting the top of the popper.
Drop down to 1/3 cup and see what happens.  If that doesn't work,
there are many ways to hotrod your popper to gain control of roast
profiles.  Google is your friend.

Dave,
I second Randall's suggestions. Best course is to reduce the amount of beans
you are roasting. As you become more familiar with specific varieties, you
can use a bit more coffee to speed up the roast or a bit less to slow down
the roast, depending on your preferences for those specific varieties. As
Randall says, if you are handy you can modify your popper by putting
separate controls on the heat coil and on the fan. Lots of help available on
the web that you can easily find, athttp://www.homeroaster.com/homemade.htmlor through google.
