Experiment with Breadman TR441 Breadmaking Machine.



Goodwill yesterday, $1.50 for a NEW machine.

I have 2 bread machines and this one has a much smaller footprint.

The bowl is a square cyclinder, and the machine is a 500 Watt unit.

The only thing missing is the stirring paddle.

I took it apart in just a few minutes with a Phillips screwdriver.

The first task was to attempt to manually control the motor with a
switch.

After much searching, I accidentally found a very easy way to determine
what 2 points to connect.

I started the machine and like all breadmakers that I have used, it
pulse turned.

The motor is connected to the control board with 3 leads.

I measured the AC Voltage between the Black cord wire and each of the 3
motor contacts.

One went from zero to 120. That's the one.


I turned off the machine and I connected a wire between the 2 contact
points.


Of course, the motor ran contunuosly. Done!


Next, what temperature would the baking chamber go to if the 500 Watt
heater coil would be on continuously?


I wired up the coil to 120 AC and I waited 15 minutes.


Surprise! 450 HOT degrees!


IOW We can consider roasting in a modded 500 Watt bread maker with no
external convection oven or heat gun as a source for additional heat.


After, the Hi temp test, I ran the motor again to check if the bearing
was still OK. The motor turned smoothly and quietly.



BTW I intend to keep the timer function as designed.to time the roasts,
not to control the unit.

The motor control bypass should not affect the machine (nor will the
heater bypass).

A BM has a much stronger motor than a SC and I believe that the chamber
shape makes for better roasting.


I intend to use a heat gun to blow out the chaff and for cool down.

Outside of course.

What fun for $1.50!

I hope that this information will encourage others to consider using a
modded breadmaker roaster.

Though the same article warns about not heating Teflon over 660=B0F...
and others suggest that it's degradation may begin occurring as low as
460=B0F, though whether anything harmful is released at this temp can
probably be debated.

Teflon is not PFOA.

Glad you asked, the research was worth it.

You'd probably have to replace/expand the factory stirring paddle anyway -
the ones I've seen are all very small and probably would not be adequate to
stir the coffee sufficiently. Just guessing though.

I also wonder whether the teflon pan will like being heated to 450 plus
while largely empty.

Well there's a couple of people over on the Sweetias Homeroast List
that are doing it.

Not to rain on your parade and $diety knows I'm not
an expert in roasting coffee.... Don't know beans about
it beyond what I read here.. but

arn't most roasters using air to get the chaff out and
a bread machine would need some sort of vent system to
remove chaff?
