Topic: When to add beans to Hottop (10 msgs / 162 lines)
1) From: Zara Haimo
I have the digital, non-programmable Hottop.  It's simplest for me to turn it on, add the beans, and walk away until the roast is almost done.  I just made the mistake of looking at the manual for the first time in ages.  Now I'm wondering if I should follow the directions by letting the Hottop heat up first and add the beans when it beeps.  Has anyone done any side by side comparisons of roasts where the beans go in early vs going in when the Hottop is pre-heated?  Any recommendations?

Always better to add beans after pre-heat. Outside temperature is a very
large variable. For soft beans (low altitude) beans I often wait until drum
temperature rises to 250. In addition do not walk away from machine while it
is roasting. You are inviting potential disaster of a chaff fire and
complete meltdown.

I, too, have a non-programmable Hottop.  I wait until it beeps after the
warm up.  I have wondered, though, is there any good reason I couldn't put
the beans in earlier for a bit of a longer roast?  I have trouble hitting
the darker roasts without timing out (even after using up all the "plus"es).
Wisdom out there?
Grace and Peace,

Temperatures here in paradise are fairly constant - in the summers it's 
usually in the 70s when I roast and in the winter it's in the 60s.
I keep the drum pretty clean - shake out all the chaff I can every couple of 
roasts.  I didn't think chaff fires were a significant issue with the 
Hottop.

My experience is that waiting until several minutes after the beeps, to 
give more of a pre-heat to the roast, yields better roasts.

Tim,
IMO leaving beans too long in that low heat risks excessive drying.  
Especially if the greens have aged a bit. Add the beans later.
Smaller batch size is one way to get the beans roasted more quickly. I  
roast half pound batches. If I wanted more control or faster roasting  
I would lower that amount. Ensuring your roaster is receiving full  
voltage is another possibility. Mine averages 124 volts which is good  
for roasting - but not so good for lightbulb filaments :-(. If yours  
is much less than 120v that could slow your roasting. Third thing that  
comes to mind is to be sure the roaster is clean, especially the  
little button thermostat.

I've never tried a roast without some sort of pre-heat.  I usually let it
heat up past the beeps, until 200 or 250 depending on bean, and what type of
profile I'm trying for.

60s are cold for a machine that is relying on ambient air. You are still
describing a 10 degree fluctuation. there will be no consistency between
roasts of the same bean with that much fluctuation. The weather here in
Hawaii is much less variable than back east in California and I still get
much more consistent roasts using pre-heating.

The variation in temperature here occur over months, so I don't think 
changes in the ambient temperature have much effect on roasts done a few 
days apart, but you are right that I should pre-heat for more consistent 
results overall.  Thanks, Barry, and everyone else who replied.  I should 
have read and followed the *&^% manual.

Here in the higher latitudes (NJ) I have a lot more variability in my
ambient air, but I still roast outside all year around.  I have to make some
adjustments as the weather gets cooler,  but I'm still able to do any type
of roast I want,  and don';t notice a huge difference in roast times.  I'm
assuming the pre-heating takes care of this.  (I do need to run the heater
at full power for more of the cycle than I do in the summer).
