the roast is complete I shut off the heater coil and cool the beans with the fan, question I have is, Is this sufficient or should I pour them on a cooled cookie sheet or some other method of cooling the beans quicker. Chet |

I always cool in the popper by shutting off the heat. Normally after 2 to 3 minutes, the popper will run out of cooling capacity and then I dump the beans on a tray to finish. IMO cooling any faster will gain you nothing. |

The answer depends on the roast level you wish to achieve, and how close you roast to it. Since there is probably a good amount of residual heat left in the roster even when the heating element is turned off, a roast that is taken deep into second (or a bean that needs a very precise roast level) would be best served by some other methid of cooling, like another popper with no heating element.

The P1 has a ceramic element which stores a lot of heat; this is great for roasting, but not so great for rapid cooling. |

A lot of motors and diode bridges have died from newbies split wiring their no P1 poppers because of this reason. But then you already know this. Ben |

Jim says the P1 is slower cooling than the FR or P2 because it has a ceramic element. Ben agrees, because the fan on the FR and P2 is series wired with a secondary heating coil. It seems to me that a secondary heating coil should make the FR and P2 slower to cool. I haven't timed my P1 to 150 F, but it drops to 200 F with 5 oz of beans in about 2 minutes. Dave S. |

I disconnected the secondary heaters; and with six ounces of beans, using an FR roastchamber, it takes about 2 minutes to get to 300F, and then it really gets slow. I transfer the chamber now to my backup for cooling, and am considering using a ventilating fan setup for really fast cooling. |

My P1 does under two minutes. Others, dc fan types, won't do under 3 minutes without the 2'ndary fan cutout. > Jim says the P1 is slower cooling than the FR or P2 because it has a > ceramic element. > Ben agrees, because the fan on the FR and P2 is series wired with a > secondary heating coil. > > It seems to me that a secondary heating coil should make the FR and P2 > slower to cool. > > I haven't timed my P1 to 150 F, but it drops to 200 F with 5 oz of beans > in about 2 minutes. > > Dave S. |

Is there a way of wiring the P1 using a 1500w dimmer, without using a transformer Thanks, Steve > > > > I find mine takes 2 minutes longer, 5 rather than 3 for the FR or P2, > > to cool the beans down to around 150F > > On those; of course. since they use a heating element to provide a > voltage drop to the dc motor.

However most 1500 watt dimmers cost about the same as a variac. Take to bottom off and you will see the two posts the feed the heater. Put your variac in series (in line on one side) with teh heater.

Thanks for the info! I was lucky enough to find a couple(1500w dimmers) for $6. Regards, Steve > > > Yes.

If you boost your fan,and tilt you can hit 255 gr green (9 oz) which gives you about 1/2 lb of roast. |
I use the exact procedure Ken described and it works great for me too. I don't see a bit of difference when I cool any faster.
