    Overloaded coretto

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    Tried roasting 600g Eth Har in my BB280,
    Bitt off more than i could chew i think, temps ramped well early on but struggled getting to FC and again to SC. Schorched a few beans >:( by putting heat gun too close to beans at one stage (only a few). Bit of an uneven roast.
    Once it got to SC I took it a little longer into it as i was after a darker roast ended up between CS10 to CS11.
    hoping i havent wasted them, will see on a few days

    What type of heat gun are you using Phil? I regularly roast 600 grams in mine without any problem using a Bosch variable temp set on approx 450 fan speed 2, positioned about 3 inches above the beans, I have half of the pan covered which I suspect helps with heat retention , even wondered if it would handle a KG.

    Merry Christmas,

    Jon. :)

    600g is my standard starting mass - it delivers a neat half-kilo roasted. Ive not had problems except that sometimes with quite wet beans they need a little help in the first 3 minutes until they lose a little of the initial moisture.

    Using Ryobi heat gun with the variable heat setting, 2000W. I usually roast between 400g and 500g. As I watched it going it didnt seem to be stiring the baens as well as usual. hence the slightly uneven roast. from about 205 deg onward, it was really sluggish rise. got there in the end. Just concerned that the few that got burned wont effect it too much.
    Merry Christmas to you too :)

    Re: Overloaded coretto

    Gday phill,

    Ive roasted a lot of harrar and find it needs more hands on attention between cracks. I consder it my nemesis but have found great results pulled a couple of degrees before SC. CS 8-9 (with a couple of 10s).
    I also ramp towards an early FC (starting at 9-10 min)to accentuate the blueberries. My preference.

    I also use a variable Bosch and roast 625g batches (4 to a bag).

    Keep at it. Worth the effort.

    Phil, I did 200 plus roasts with a 2 speed Ryobi 600g batches with no problems, nice even roasts no tipping.

    Jon, I experimented with a Breville big loaf twin paddle and 1.2kg batches but it was hard to control the heat and I ended up with beans with a charred taste and tipping, I dropped back to 900g and that worked well with better control and ramping etc, but I still find 600g the best for good heat control.

    Thanks Greenman, mines only a single loaf single paddle so you may well have answered my question.
    Do you roast with the top open, covered or partly covered? :)

    Same experience with my Big Loaf and Ryobi 2-Speed gm.... Although, with my original Aldi heatgun, I experienced no problems whatsoever with roasting batches up to 1.2Kg, and could comfortably roast 600g batches using it on its Low setting. Was a bit of a beast that heatgun and I miss its versatility.... :)

    Re: Overloaded coretto

    Unfortunately not Jon.... :(

    Aldi do have heatguns advertised occasionally but from a couple of inspections I made of them, they were quite obviously sourced from a different manufacturer so that put me off buying one.

    My old one was supposedly rated for a 2,000W output but it was more likely upwards of 2,400W.... never tripped the breaker on my portable RCD unit but it must have been close.... ;D

    with my single paddle bm the top open with *Ryobi 2-speed
    am experimenting with the twin paddle, Makita variable temp and fan hg *and semi covered at the moment 600g and 900g batches are roasting nicely with good control but any larger and it all goes haywire ::) ::)

    Re: Overloaded coretto

    Hi Phill,

    I run a BB270 , which is a small ,square shaped basket, with one paddle and this has always limmitted the size of my batches...... every 500g batch has struggled , I mostly do 430 - 470 g.

    I think it is part of the learning curve to know what YOUR coretto is capable of.
    A lot of folks here will say 2/3rds of bread capacity , but that is a generalisation with way too many variables to be strictly adhered to.

    Cheers

    My personal experiences with 3 different BMs have come in a lot less than this actually, more like 50-60% of what ever the maximum loaf size stated by the maker.... ;)

    700gm in winter say 10deg and 750gms in summer in the same BM quoted here with a Ryobi 2000 8-)

    All good

    Thanks Guys,
    There was no waste as the beans still taste great. Will stick to 500g and under though to maintain a bit more controll.
    Happy New Year to you all too :)
