  • Why Not Cover the Breadmaker?

    The BM/HG Corretto is an awesome fun roaster!  8-)  Many of you know.  In threads and pictures though, almost no one uses a cover on the breadmaker.  

    I wonder why more people dont use a cover?  :-?

    I have a controller to vary the heatgun temp, and use a cover and a couple of TCs to monitor temperature.  I close the lid but can peek in on occasion to view the beans, and I learned here to be sure the bean temp ramp doesnt stall!  Without a lid, the bean temp would have more opportunities to stall during the roast, wouldnt it?

    I have seen corretto setups with lids over the BM and TCs straight into the middle of the beans.

    I would think that with a lid over the BM, you wouldnt be able to hear the cracks as well?

    and you wouldnt be able to watch the beans change color with a lid!

        My breadmaker has a built-in vent at the top, rear of the lid. 30% of the chaff goes out that vent and lands on the workbench, 60% of the chaff blows over the top of the canister and falls to the bottom of the interior of the breadmaker. The workbench and interior of the BM can be cleaned with one pass of a shop vac. 10% chaff is left with the beans at end of roast and is dealt with during cooling. I dont mind a little chaff in a home roast, but Im not selling commercially...

          I use the existing BM lid, so I can open it to peek at the beans. The roasting smoke and smells are just as telling as the color and sound. Although I can still hear the cracks very clearly through the mechanical noise. The (very cheap) heatgun Im currently using is much quieter than previous models, which helps too. I also roast .5 Kilo to 1 kilo batch size and with that amount of beans the cracks are very easy to hear. I can understand where a 250g batch may not be so easily heard.

            Gday seedlings,

            The uncommon use of the BM Lid or other form of cover is probably due to the fact that most Aussies tend to live near the coast, close to sea level where average daytime temperatures are mostly balmy to hot for much of the year. Probably just doesnt seem to be necessary and besides, I enjoy watching the beans go through their paces as the roast progresses, half the fun.....

              Well, now, I hadnt considered weather, Mal. Where I live there are "seasons". Today its 11C and raining, and we call it "spring".

              We vacationed at the ocean last year (Florida, not Austrailia) and oh, man Id love to live there. Were going to try a mountain vacation in a few weeks... I think Ill still prefer the ocean.

              I agree and enjoy watching the beans myself. Fascinating every time.

              Watch out for the blue bottles,

                I hear you Chad, its about 10 degrees here and hosing down with rain. Thankfully I got a roast in yesterday. Im in the same camp as you with the lid on the BM. I modified mine so I just have the metal interior of the lid (none of the fancy plastic surround) with the HG poking through where the glass panel used to be. I dont need this if Im doing a 200g batch but without the lid anything more than 200g takes too long to get the temperature right up. So, since I prefer my batches around 750g (gets a more even roast that way) I use my lid most roasts. Since its only the metal interior of the lid it gives reasonably good heat protection but I can hear the sounds easily, and if I flick a torch on I can see inside as well. The chaff situation is the same as you - some blows up past the HG but most collects underneath the roasting tin. Very little ends up in the roast itself.

                  Hi all
                  I use a lid on mine, its very hi tech and called "wood" not an original concept as a frew CSrs are using this method already i believe.

                  I just place it over about half of the bm bread pan area and that still leaves enough space for all the chaff to be blown away but what it does do is enable me to run the HG and a much lower temperature as the roast progresses. The result also seems to be a much more even roast to the beans in general than what i was using before.

                  Last weekend i was roasting in 7deg C ambient temps and the cover definitely helps there.

                    I wont use a lid here in Perth due to our mild climate but I can understand roasters wanting to use a lid in a very cold climate to retain heat and help with the evenness of roasts.

                      I wish I had a shed as well. Thatd keep the wind at bay.

                      Also, I wish I had a shed right now - a new batch of greens arrived today (PNG Sigri, Indonesian Mandheling, Indian Mysore, and Brazilian Ouro Fino), all of which I havent played with before but its raining outside! Oh what horrible luck.

                        Probably ambient temp as Mal said, though in Melbourne the other day I did a roast at 9C and it was fine without the lid.

                        Most of us Aussies also use a TC, so irrespective of the lid, we can control the the temp rise as desired, [ie no stalling]

                        Ive played around with lids, the only real gain I found was that I could achieve a desired roast profile with my HG set to a lower temperature.

                        Otherwise, the lid slowed down the process of dumping the beans, blocked that lovely spinning hypnotic view, made it harder to watch the colour & hear the cracks, and the roasts retained more chaff.
                        None of these are major issues, its just that the benefits of no lid seem to far outweigh any gains from using it.

                          I used wood (lined with aluminum) until I realized I could remove the square viewing glass from the top of the BM lid and stick the gun in there.  With a lid, I can do these batches without losing beans. This is a Sumatra, stopped after first snaps of 2C, but before rolling 2C. Chocolate and tobacco spice as I remember.

                            I have made a lid for my bm with 2 "chimneys"; one for the heat gun and one to take chaff out. It works great at pointing the chaff out the door.
                            I decided to use a lid to stabilise the temp in the bm a bit more from wind gusts. There was also a mention that drum roasters have a lower throughput of air and this set them apart from correttos. With the lid on I can run the heat gun at a slower fan speed but still maintain the temp ramp. The cracks are easily heard even with the lid on.
                            At the qld roast-off there were a few of us using lids so it isnt just for the colder states.

                            Downside is that I cannot see much of the beans but I use the temp to decide when to pull my roast in any case.

                              I did try what seedlings has done, remove the glass window in the top of the BM lid but found with the model i had that it just wasnt enough space so as a result chaff wasnt gotten rid of and the HG being so close to the plastic of the cover gave off a really bad smell as it approached melting point.
