Popper Chimney

Re: Popper Chimney

Often increasing the batch size a bit will extend the roast time. Give it a shot, and see if you cant extend it a bit.

Hmmm,

Thats interesting nunu.... my popper has exactly the opposite characteristic. The more beans I add, the hotter the roasting chamber temp and then the shorter the roast. Ultimately I reach a point where the fluid bed will no longer work and the thermal cut-out operates soon thereafter. Must be some kind of weird thermal inversion scenario going on here :-?. Anyway, it doesnt really matter so long as it is doing what you want ;D,

Re: Popper Chimney

My popper has a limit of 150g green beans. Any more than this and it shuts off. 1st crack comes at varying times depending on ambient temperature and bean type. An example of a roast profile can be seen here: http://coffeesnobs.com.au/YaBB.pl?num=1128647911

Re: Popper Chimney

Hi Mal,

I previously found that 110g was the sweet spot , now I think your right Im unfortunately have to reduce my batch size .

Re: Popper Chimney

Hi ,

Thanks for that guys, Ive managed to get a tin can and have used it to roast a batch of
El salvador beans . The roasting time was much shorter 1st crack was at around 3min , 2nd crack was as 4min er approx .
I wonder if there are there any other objects that anyone has used as a chimney.

Hi again Paul,

Out of interest, whats the size of the batch you are roasting in the popper? You might have to reduce it by 5-10 grams to see if that lengthens the roast time back to what youre happy with. Regarding other paraphenalia that you could utilise as a chimney, I think the modified Milk Shake Cup sounds good.... youd have plenty of length to play with in case you need to adjust its fit into the popper more than once, and being s/s you wouldnt have any worries about melting plastic or other possible contaminants. Might be worth a go ,

the roasts I was getting witht the lantern cover were much longer 1st crack at around 4-5min 2nd at around 6-7 (depending on the bean and ambient temp ) .
I think the main reason was the shape it had quite a wide base which tapered off to the top, I wonder if there are there any other objects that anyone has used as a chimney.

Re: Popper Chimney

I used a Golden Circle fruit juice tin (apple juice). These tins are even bigger than the very special soup tins and they DONT have any lining - just the tin. Perfect.

I also just cut a slit up the tin like Nunu, it secures itself much better.

Re: Popper Chimney

I dont even bother cutting a v in the tin. I simply cut about 2/3 the way up the tin, and gently squeeze the bottom so it folds over itself.

Sounds good nunu [smiley=thumbup.gif]

You also should use a can opener to remove the band on the bottom of the tin. Makes overlapping the bottom of the tin much easier. then you just push it down a little ways into the popper.

Yep, always do this.... pretty well impossible to fit otherwise :P

Bobs one of your relatives (Bob is a very common name ofc, so you may have a few besides your uncle).

As a matter of fact, I think there is only one Bob in our entire extended family, and hes a cousin twice removed, I think :-?.

Theres a small screw inside the chamber, and I dont push the tin down anymore than that. Pour in the beans, put on the popperdom, turn it on, 30 second shake, and Bobs one of your relatives (Bob is a very common name ofc, so you may have a few besides your uncle).

Re: Popper Chimney

Yep,

Broke my Lantern Chimney a while back too >. Without missing a beat, grabbed one of a few empty soup tins that I keep on hand for such occasions, snipped the V out of the bottom after removing the base and Bobs your uncle. Most of our soup has been the Heinz Special variety in the extra tall tins, and these seem to work extremely well 8-). Dont think Ill bother with replacing the Lantern Chimney, even though it allowed great visibility for gauging the roast progression by colour.

Re: Popper Chimney

But pea soup and ham... :-? We used to make it at another restaurant I used to work and, and it always stunk up the place. It isnt all that aesthetically appealing in the first place, so it needs a bit of help.

Re: Popper Chimney

I think I used Campbells Pea Soup and Ham. It came down in the end to which soup I liked best and Campbells got my vote.

Re: Popper Chimney

I use a tin of Heinz Very Special vegetable barley soup. It has a white lining, but that hasnt come off at all, or scratched. Its taller than your average tin, so the height really helps keep the beans from flying all over. You might also look at a tin of asparagus, those are usually longer than normal tins.

Re: Popper Chimney

Hi
I used a stainless steel milk shake cup that i picked up from costplus stores and cut the bottom out of it

Ive used tins containing peeled Italian tomatoes as a chimney and they have worked very well. Better than the lantern tops IMHO.

Hi ,

Ive been using a lantern glass for a chimney for my popper , unfortunately Ive cracked the glass . Anyway to get to the point I need a chimney and I bought a number of different tins to use as temporary measure but every can Ive bought seems to be lined with plastic , that tends to melt and gets onto the beans , Yuk! . Does anyone know of a type of can that isnt lined with plastic , Ive got down to the last of my roasted coffee , the situation is getting serious.
