Alchemist Builds: How to modify the Behmor Roaster for Profile Roasting

[@aaronmaddern979]

can you tell me please - has there been a considerable amount of wear on the probe where the drum rotates around it? TIA

[@HowToMakeChocolateAtHome]

Since I made this video there is no wear showing at all.

[@levipatrickdiaz]

Do you have a newly recommended thermocouple and digital thermometer? Looks like it's not easy to find the MS6500 right now nor do you sell it, and the link for the Omega thermocouple is also dead.

[@HowToMakeChocolateAtHome]

Any Type K, ungrouded, 1/8" thermocouple will work. Likewise, any thermometer that accepts a Type K thermocouple will work.

[@geraldl5221]

Looks like the Omega thermocouple has been discontinued, any alternative you may be able to recommend?

[@Phewy]

Man, you make this look so easy!

[@HowToMakeChocolateAtHome]

Thanks. 20 years in the shop, the right tools and LOTS of failures will do that :) Just take your time and follow what I did and you may find it isn't so hard.

[@johnclark3143]

I just did this and was slightly off center. There is a small opening on one side of the slot where the drum end gets narrow, but it seems to still work fine. I've been over roasting my beans (they've been roasting very quick for whatever reason) so for minimal work effort it was worth it to try this.

[@MikeFLHT]

This looks like a very cool project and I am definitely going to dive in. I have a question: I see the probe inside the drum and it is right in the middle of the inside of it. When I watch my beans in my roaster they are pretty much roasting at the bottom of it as it is turning. Does the probe actually make contact with the beans?

[@HowToMakeChocolateAtHome]

It does if you use 2-2.5 lb.

[@MikeFLHT]

@@HowToMakeChocolateAtHome Hmmm. In 1 lb roaster? Explain pls.

[@HowToMakeChocolateAtHome]

For clarity, the thermocouple modification is only meant to be useful for cocoa where you can and actually need to roast double the amount you would roast for coffee since cocoa roasts so much cooler. If you are talking about cocoa, then you should not be roasting only 1 lb. Does that clarify?

[@MikeFLHT]

@@HowToMakeChocolateAtHome aha! Now I get it. Thanks for clarifying. 👍

[@dariusrh.8507]

are the dimensions of the 2000 the same as the 1600? I'm guessing this was on the 1600? thanks!

[@HowToMakeChocolateAtHome]

Yes, the only difference in models is the programming and circuit board updates.

[@buenaxx]

Thanks for this video, very helpful ! I'm about to get the Behmor 2020SR Plus. Does modification applies the same way with the new version of Behmor? thank you

[@HowToMakeChocolateAtHome]

Yes it does

[@buenaxx]

@@HowToMakeChocolateAtHome Thank you

[@dianaa2877]

any recs for thermometer/ probes other than the mastech? thanks :)

[@jaguara2440]

Nice project! I have a doubt: very carefully, can you make the hole with a drill in your hand?

[@HowToMakeChocolateAtHome]

it is pretty hard by hand. The stainless isn't a fan of hand drilling. It is easy to snag and snap the bit. Regardless, use lots of cutting oil.

[@coffeeillusionist8263]

I did it. Was not fun.

[@billydiaz806]

What temp device were you using?

[@harryelliott7362]

Where do you bend the probe? How much should be inserted in the oven itself? Thanks.

[@HowToMakeChocolateAtHome]

About 5" from the end or so. And as much as will go in given the bend.

[@harryelliott7362]

Thank you! This is my next project. :)

[@yananRamirez]

Really nice video, and thanks for that way, only a doubt , i believe Jhon Ben had seen this video and modified the roaster, now it has a Drum, Internal Chamber temperature readings

[@HowToMakeChocolateAtHome]

Internal chamber tempering is no help at all to know what is inside the drum and what temperature the beans are if that is what you are saying.

[@yananRamirez]

@@HowToMakeChocolateAtHome you are right, I'm really a fan of your channel. Excuse me my unknown, thank you.

[@HowToMakeChocolateAtHome]

No problem. I just don't want you to mistake chamber temperature for anything related to bean temperature.

[@diegojoachin]

@@HowToMakeChocolateAtHome Mere curiosity: Then what's the point of Behmor putting that up?

[@HowToMakeChocolateAtHome]

So if you pre-heat you can go to the same temperature. They also take pains to say it is not to be used to actually roast by.

[@taylorwhite3636]

Use a mastech ms6514 or a phidget to track temperature in artisan

[@mrchulondon]

Surely your just getting the temp of the drum where the couple passes through rather than the bean temp?

[@HowToMakeChocolateAtHome]

No, not at all. With 2 lbs the probe is inside the bean mass.

[@Jonathan-ol9jy]

You can roast 2lbs on a Behmor? I thought the limit was one.

[@HowToMakeChocolateAtHome]

2 - 2.5 lbs of Cocoa. 1 lb of coffee.

[@paulvanier429]

This still only measure the environmental temp, what's the point?

[@HowToMakeChocolateAtHome]

The point is that when you roast 2 lb of cocoa, the thermocouple is no longer in the environment, it is in the bean mass.

[@billydiaz806]

Very Good.
