    Looking good!
    Let us know how it cups 

    Matt

    Sorry I took so long to reply, but the Peru was fantastic. Almost as good as the Brazil Yellow Bourbon I did after the Peru.

    Anyway, more recently was the PNG Wahgi.

    For background, I have the Ozito HG, I also labelled a scale of 1-20 on the HG, to give some kind of numerical representation of the heat level.

    So to the graph below, thanks to pcf1978 for this template. The red xs are my approximate temperatures.

    And here is a description of my temperature levels along the way

    0min to 2:30 - Level 18
    2:30 to 4:30 - 17
    4:30 to 7:30 - 18
    7:30 to 8:30 - 19
    8:30 to 12:30 - 20
    12:30 onwards: 18

    And I reckon they turned out pretty well. Sorry for the bad lighting in the photo though... Ill let you know how they cup once Ive let them rest for a few days.

    Alrighty. Its been a while. So I thought it was time to make an update.

    So I ran 500g of the the Peru Ceja de Selva Estate through the coretto today. I used the Dough cycle this time, 5 minutes of intermittent mixing, then 20 minutes of continuous mixing. I had the HG on the lowest setting during the intermittent cycle, stirring continuously with a wooden spoon. Cranked the heat up slowly over the first 8 minutes of the continuous cycle, think first crack occured around 12 minutes (including the intermittent 5 minutes), then second crack at 18, when I began cooling.

    Quite happy with how they turned out. Shall let you know how they taste over the next few days!

    Hi D8
    Im using a BM with the same pan and with 350g there is no worries about beans getting trapped in the corners - the mixing is pretty consistent. It is also a better roast size for controlling - I used to do 150g batches and it was really hard to get consistency.
    Also, the gun down into the corner (I use the front right) does help blow the beans around.
    Im suprised you had the machine stall at 15mins - were you using the dough cycle? In my Breville that goes for 30mins. I use the first 2mins of eratic mixing for a gentle preheat, then into it - takes about 20mins.
    Great fun though, isnt it 

    Matt
    Hi matt! Thanks for your reply. I was using the pizza dough setting. But i will check out the dough setting soon.

    David.

    Try running the BM again on the same cycle with-out any beans or heat and see what it does. Its possible its temperature protection kicked in and stopped it. Per the manual for your machine (http://www.breville.com.au/media/mediaappearance/11579/BBM300_LORES.pdf) there are any number of settings that will give you a 20 minute knead cycle.

    On a quick glance through the manual I saw no setting that had a 15 minute knead cycle which is why the suspicion that it may have been an over-temp protection issue. If so the BM will require some modding, which is addressed in any number of threads on here.

    Bread makers have a temperature sensor? Well thats annoying. Although id imagine it would be quite a simple mod, yes?

    David
    Yes, you can usually relocate the temp sensor. I did it recently, it helps for back-to-back roasts

    Extending the paddle may create a new problem. A BM I was using had very little clearance between the end of the paddle and the narrow side of the pan. This would cause the beans to pinch and either fly out or actually jam and stall the motor. I had to grind it down.

    Thundergods suggestion of increasing the batch size seems to be a good one. Its Beanbay night tonight!

    Also, Im using the the same HG as you, I just run it flat out and adjust the height as the roast progresses. Not too sure if thats the best way, but I decided not to make any adjustments on the gun while its hot. I imagine theyre fairly flimsy inside.

    Thanks for that. Looks like I wont be extending the paddle then. Thanks for your help!

    Im wondering if I could extend the paddle to reach the sides?

    If you look at your picture theres a lot of space in that pan.
    If you had more beans the paddle would push some beans and they would push the beans in front.

    Put some beans in without using the heat gun and just watch how they travel around the pan.
    Then add a few more and see how it changes.
    Put 1 or 2 roasted beans in too make it easier to follow the way the beans flow.
    Sounds good. The only reason Im using such small batches is that I bought the CS starter pack, I only have half a kilo of each bean type. And Id hate to screw up over an entire batch.

    It was 200g. What would you suggest? Is there some golden rule? So, more greens will force them to spin more, is that correct?
    When I was using a corretto I started with 300g batches and progressed to 600g.
    Now 300g is trickier for me because Im used to the dynamics of the larger batch size.

    maybe I could aim the HG further into that corner.
    Exactly what I was thinking.

    Doesnt look too long; close enough to square to do the job I reckon.

    How large was that batch in the picture?
    Looked a bit small to me.

    I used to aim my HG towards the further corner (the top right one in your pic) making sure it was blowing the air in the same direction that the beans were travelling.
    This gave them a bit more of a push into that corner and helped them around it.
    Yeah, that was my goal also, maybe I could aim the HG further into that corner.

    My biggest concern with the roast was that the pan seems to be quite long, rather than the optimal square.

    the beans seemed to get caught at the ends of the pan.

    Re: Journey into Home Roasting

    Hi all. Its been a while. But now Ive finished exams! Ive been acquiring my correto setup. Breville BB300 BM, Ozito HG. I did a dry run without beans a few weeks ago, and Im sure I found a setting where the BM ran on the continuous mix for 20 minutes. However, 15 minutes into the roast today, it decided to stop. So, my roast is a little lighter than I had hoped, but it still looks good (I think). First crack was at 7 minutes. Bit early, but considering I only had a 15 minute roast, Im kinda glad.

    I shall sort out which setting gets me the 20 minute mix for the next batch.

    My biggest concern with the roast was that the pan seems to be quite long, rather than the optimal square. Thus, the beans seemed to get caught at the ends of the pan. So I was stirring with a wooden spoon the entire time. Im wondering if I could extend the paddle to reach the sides?
