A belated thanks to those who responded to my post concerning my Alp which was running very cool. I went so far as to contact Swissmar about returning the unit, when I suddenly had a roast that hit first crack at @15 minutes and finished 30 seconds in 2nd crack around 18 minutes. When I looked for any factors that might have changed, I realized that I had forgotten to turn on the exhaust vent setup I had constructed soon after buying the Alp until the smoke started at the onset of first crack. Then it dawned on me - I was sucking too much hot air from the roaster with the vent fan! I made two changes that have completely solved the problem. 1) I turn the Alp vent assembly to face downward during the roast so that it isn't facing the vent fan. 2) I don't turn on the vent until the first signs of smoke - usually around 12-14 minutes. Here are some pictures of my setup www.trancho.net/javastuff/ I'd appreciate comments from other Alp owners who have made vent setups. I think that I made mine too low - it just clears the Alp by 1/2" or so. This may also help other Alp users who vent their roaster in a similar manner.

In the picture of the variac, is that the variac from that place in Arizona near Phoenix? ~$110 delivered? -- Rick homeroast mailing listhttp://lists.sweetmarias.com/mailman/listinfo/homeroast |
Rick, The metal box is the guts of the bathroom fan - there is no real need for the plastic stuff that you'd use if installing it in a room. I bought the variac from Circuit Specialists (www,webtronics.com). Bob <Snip> homeroast mailing listhttp://lists.sweetmarias.com/mailman/listinfo/homeroast |
Bob: I have a similar venting setup for the Alp as you. However, my hood might have a little more headroom than yours has. Check out:http://www.beyondthesecondcrack.com/AlpVenting.htm My Alp consistently works in the 17-19 minute range for darker roasts. I turn on the fan when I start the roast and it runs throughout the roasting cycle. Ken Parker (I've referenced these pictures a couple of times before, but every 6 months or so someone raises the Alp venting issue. To the old timers on the list, please accept my apologies for "over posting".) |

I'm thinking that I'll just add about 3 inches around the base to bring it up higher. Bob Trancho homeroast mailing listhttp://lists.sweetmarias.com/mailman/listinfo/homeroast |
