    New Corretto build.... Does smoke affect beans

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    Just built a new corretto based on a BB400, which provides for larger batches than my old BB270.

    First 2 batches in the BB400 were today and I noticed that my lid was so snug hardly any smoke came out .

    At this stage I haven't tried any of the new roast But.... will the smoke affect the taste?
    Or should I add some breather vents to the lid ?

    Thanks

    If you have little/no exhaust, wouldn't your heat gun air flow be restricted?

    Cheers

    Not that I could notice, compared to my regular roasts in the BB270 I had to push the temps a bit more , but I was jumping from about 380g to 550g so you would expect that more initial heat would be required. Between FC and SC the roast behaved much the same as old.

    My new snug lid has about 2mm gap around the HG nozzle..... But I did notice smoke exiting out of the louvered vents in the outer case of the BB400 ( difficult to work out how it transited to there , but made me think ).

    I thought that if I made the lid snug my chaff would be contained away from roasting pan and trapped in BM near the old heating element, and it is. So that worked ,but I'm not sure if excessive smoke is going to taint the roast...... Probably find out next week when we start to drink from this 1st batch.

    Cheers

    My corretto has a 60mm dia hole in the lid to let the air/smoke out. For me, the lid simply stops the hot air from blowing into the cavity around the baking drum.

    As artman says, if you restrict the airflow I would think you have a good chance of blowing the heat gun. Usually the heat guns have a non-fixable overheat "fuse" which works once. If you overheat it, you have to buy a new gun.
