Subject: Panasonic SD-BT55P cycle details

I'm providing this info in hopes that it may be helpful to a wanna-be home roaster who (1) wants to try HGBM (heat gun + bread machine) roasting and who (2) is planning to use a Panasonic Bread Bakery SD-BT55P bread machine like the one I found at a rescue mission thrift store.

This machine, like most others, I presume, has a period of very brief pulses and short spins before really getting down to business. I can't find a way to override the pre-set cycles of the machine without making a hardware modification. Still, you can get about 14 minutes of uninterrupted paddle-turning time if you're patient.

Using the "Basic Dough" mode, here are the details of the cycle, indoors at room temperature:

START: Display shows 2:25 (i.e., 2 hours, 25 minutes).

PHASE 1: About 30 minutes of rest.

PHASE 2: Display shows 1:56 – Things come to life with pronounced “clunk” noise. When the display shows 1:55, the paddle whips around for about a minute, with a couple of clunks and a stop or two.

PHASE 3: 20 one-second spins,

PHASE 4: 10 two-second spins.

PHASE 5: 5 twenty-five second spins

PHASE 6: 10 fifty-nine-second spins

PHASE 7: When the display shows 1:39, the long spin begins. It lasts about 14 minutes. This is when you can roast coffee without interruption.

PHASE 8: After the long spin, when the display shows about 1:25, the machine goes back to rest state until the end of the full 2 hr., 25 min. cycle.

The upshot is that, in the Basic Dough mode, you'll need to wait about 45 minutes after pressing "START" to get to the stage where you can roast with a continuously spinning paddle.
