Modify the Behmor?

[barrel]

No mate it wont extend the time of that leg only the last leg which ramps up to full power again .  Give burping a try with one of the roasts.  Keeping a good record of bean weight for each bean type is important as it really is the only change you can make.

Your in the right neck of the woods though, might be time to hand it over to AM and see about setting the elements up a a variable adjustment.

I can think of a number of mods... BUT...

1: IS it worth the effort for any real change

2: IS it worth the expense

Can other do with out breaching the Electrical safety requirements of the Aus Supplier and Org Manufacturer.

Depending on what ya actually want / need and teh level of control etc... Manual override.. A number of mods could be effective..

Opps... Sorry my KKTO is feeling a little miffed as it realised a small intruder was here last night.. HAd some peopel drop over and now SHORT of beans my self... The MM has to sit a bit looooonger yet

Mr Wsully... My wrist is just starting to come good... As per other post.. Elbow still a bit touchy.

PS. How were those few beans I gave you to test and copy for those DESERTS... : : : Good thing teh wife can hold her breath :-?

Re: Modify the Behmor?

setting the elements up a a variable adjustment.

yeah not too concerned about altering anything at this stage, on hunting around on the net, it seems that there is something in the works in relation to variable profiles, not sure how long that will be off though, im more concerned with knowing whats going on in there, temp wise. There is one mod in particular (pic below) where the owner has drilled through the side of the roaster, put a bit off copper tube through the pivot point of the drum and fed a T/C into the bean mass, whilst this is easy enough to do, removal of the drum would be tricky.

Im well aware that it will affect warranty but im keen to explore the bean mass probe more as non evasive as possible.....anyone else keen? Maybe mount something off the current left hand barrel holder?

Re: Modify the Behmor?

Anyone got any suggestions on how to make the end of the barrel mount up against the wall of the behmor, like the front of a commercial roaster? this would solve a lot of problems, but, difficult to remove

The probe could simply go through the inner wall then......unless i make a door on the side of the behmor with a feed and dump hole, but then the vanes dont direct the roasted coffee out the hole.......oh the brain is swelling
;D

Any constructive thoughts (not your silly Wsully comments ;D)

Re: Modify the Behmor?

Put to side as a sample roaster..

Buy a second hand 2 or 5 kg unit..


Get a new job


Can I join ya ;D

(Draft flow of steps and review process in note pad - PM me ya e-mail or send another to my addy)

Thats called a flange
If AM has a metal lathe he can make one for you

Also search curtain rod flange

BASTARDDDDDDDD  I was trying to keep out of this one...

Or an offset and made of brass or bronze etc etc..

Crap, Alex T will have to help me hide all that stuff from MrWsully

Ok, bit of a brain strainer, but......just read in the manual, and i quote Behmor Manual V3.6, Part V, Chap 8 -

"Adjusting profiles by time additions and subtractions at proper times can be used to slightly alter the pre-programmed profiles, You can shorten or lengthen the middle leg of a profile or end leg of a profile in terms of percentage of total time. The adjustments can be made by prior to or just after starting the roast cycle"

AND

"If you wish to lengthen the roasts middle leg percentage to total and shorten the end leg, add time to start, then once started reduce the time back"

(My aim was to not only lengthen the middle leg(;D) but remove the final 100% leg too 8-)

So, for P2 B 1lb =
First Leg = 100% power= 12:00
Middle Leg = 70% power = 5:30
Last Leg = 100% power = 2:30
TOTAL = 20:00

P2 B 1lb has a max time of 22:30

So adding 2:30 at the start will total 22:30, which will give you:
So, for P2 B 1lb + 2:30 (start) =
First leg = 100% power= 13:30
Middle leg = 70% power = 6:45
Last leg = 100% power = 2:15
TOTAL = 22:30


So in theory if you add pre roast and subtract post start this is what you will get.....
for P2 B 1lb + 2:30 (pre-start) - 2:30 (post-start) =
First Leg = 100% power= 13:30
Middle Leg = 70% power = 6:30
Last Leg = 100% power = DOES NOT EXIST
TOTAL = 20:00

So, after playing around the the "behmor thing" i also have the following alternatives(which are better)

for P2 B 1lb + 1:00 (pre-start) - 2:15 (post-start) =
First Leg = 100% power= 12:36
Middle Leg = 70% power = 6:30
Last leg = 100% power = DOES NOT EXIST
TOTAL =19:06

OR

for P2 C 1lb + 0:50 (pre-start) - 2:05 (post-start) =
First Leg = 100% power= 12:30
Middle Leg = 70% power = 6:15
Last leg = 100% power = DOES NOT EXIST
TOTAL =18:45

OR

for P2 A 1lb - 0:30 (pre-start) - 1:45 (post-start) =
First Leg = 100% power= 10:30
Middle Leg = 70% power = 5:15
Last leg = 100% power = DOES NOT EXIST
TOTAL = 15:45

Bottom line here is if you dont have the "Behmor Thing" then get it, it is invaluable, you can find the perfect roast profile for what you want to do, just by adjusting the + and - signs in the roast graph section, you pick your Default profile you want to base your profile off, and add and subtract time pre and post "start of roast" to get the power changes where you want them....its kind of like a live simulation, with a graph that shows you where the power drops off and what your additions and subtractions are doing to the profile(below is a screen dump of the program in the Roast graph page).....

This Roaster is in fact Highly tweakable, you just have to have a play, and realise that the default profiles are not the only thing it can do........and for $399 off Andy.........Best value budget purpose built home roaster on the market 8-)

If anyone is unsure of what this all means, or maybe i havent put it in words well, PM me, ill try to explain it better over the phone.....

Re: Modify the Behmor?

Ok, bit of a brain strainer, but......just read in the manual

How many other units out there ?

Mr Wsully.. The anal IT and documentation person in you, in addition to ya passion; is worth every penny that a few of us found.....

I am so please that your using and adding so much back to the community; from such a small gift...

Ya should think about moving to this side of town ;D

Re: Modify the Behmor?

Ok, disregard just about everything i said in my last post..........did a roast, and the timings didnt reflect the Behmor Thing, so i sent the following email to the creator........

"When i roast, i like to reduce heat at first crack and coast to second crack in about 5 mins, i had a play with your graph/roasting tool to predict what was going to happen with the roaster, and i found that if i do a P2 1lb A roast adding 3 mins prior to start and subtracting 2:10 after starting that it will go for 12:36 at 100% and then hit the temp drop to 70% and stays at 70% power till the end, not increasing to 100% as per the stock profile..........but in reality, the roaster drops to 70% heat around the 13:00-13:30 mark and goes up to 100% with 1:30 still on the clock.....is the graphing tool on the behmor thing 100% correct? or are there some bugs in it, and also, with the behmor are these %s determined by time or temp?"

This was his responce...........

"The heat in the Behmor is controlled by time and temperature. If you want to see the actual profile, run it with the door open and no drum or tray. That takes the temperature out of the equation and lets you see the actual timings. Not that all segments start with the element on and heat is controlled in 20 or 30 seconds pieces so you will see the start of the drop about 15 seconds late. Also changing the time before pressing start has no effect on the timing of the segments, only ABC or D and the weight buttons affect that.

There may be bugs, but none that Im aware of.

Make sure in preferences to set the voltage correct and check "Hide Before buttons" as I need to remove them but havent yet in case there is an upgrade."

hmmmmmm

Back to the drawing board ;D

Re: Modify the Behmor?

WSully, there is a very long discussion on coffeegeek about how the adding and subtracting of time on Behmor does not work the way the manual states but simply adds/subtracts from the final leg.

The author of Behmor Thing drives the push for an upgrade for it to do what the manual states as this would make it much more tweakable.

Its also discussed in another Behmor thread on here.

In the end, I just manually stop it (that is remove drum and hit cool - I cool it in my own cooler) before the 100% end leg kicks in.

yep thats what i do, i just cant believe they release a product that doesnt do what the manual says.........unreal :-?

I read that thread too and Joe was saying that dealing with Chinese engineers, it was sometimes difficult to get an answer to technical questions to honestly reply to the forum.

Re: Modify the Behmor?

hmmmmmm

Back to the drawing board ;D

Yeah I think most of us bought the Behmor based on the purported adjustability that the manual states and it is a shame that it doesnt operate as stated.

Hopefully there will be a retro upgrade to the original concept at some stage.

In the mean time I do much the same as pavoniboy and set 100%/70% legs at the length I want using the A to D buttons and then eject before the last 100% comes in.

It would be a cool roaster if the leg lengths could be adjusted.
