Second roaster frustration

The TJ-067 is $3995 + GST...

I know this is a different machine conceptually from your outlined design….but "bang for the buck" - if it works as they claim - there seems to be the brain trust here on CS to automate it a bit: Coffee Crafters

It is an interesting - and simple design, kinda like a really big hot air popcorn machine.

Thanks... I feel wedded to the drum roaster model unfortunately!

Thanks Chris... appreciate your patience with these sorts of questions!

It's a somewhat of dark art Terence. That said, legions of CS'er will no doubt agree that a few simple rules followed will deliver very good coffee.

I'd argue that the reason we use different gas settings is to replicate the profile used for a larger batch as closely as possible- thereby creating a similar environment.

Taste it? Depends. I have had some clients who can't distinguish overextracted from underextracted- so who knows. Assuming that two identical shots could be pulled, palate would be the determinant on what you can discriminate.

Nope- I mean different gas to create an identical curve.

Hopefully final dumb question on this issue.

Is the taste of the coffee purely a result of the bean temp profile? Using different gas would certainly alter the environmental conditions. I'm wondering if one could distinguish between two production runs - one at full capacity with overall higher gas settings and one at a small proportion of capacity with overall lower gas settings (and likely a different profile of when gas is altered)?

Thanks,
Terence

Please let me know if there is any interest in the group roaster idea in southside Brisbane.

Thanks.

Thanks... makes sense.

Hi Matt,

I have roasted 1kg in my HSR-10 on an identical profile to 10kg....just to prove it could be done!

Realistically if you're thinking commercial venture, you need 5kg minimum to get a return on your time investment.

Cheers

Chris

Thanks Chris
Makes a bucket load of sense!

Dumb question but when you say "identical profile" you mean exactly the same heat settings through the roast, same damper changes, same fan all producing the same bean temperature profile with a similar time to roast to the same degree of roast?

Currently building a larger sized corretto hoping to get 700g + roasts.
This will be driven by PC software and Arduino to get the control I

I successfully roast 750 grams weekly in a single loaf Coretto and have been for years.
It's a simple matter of getting the heat gun and bread maker set up right, no software of any type required.

I think there is a business idea in this...

A collective of CS'ers combine funds to buy a 2-5kg gas roaster and house it in an appropriate space. Everyone has access- perhaps a small upkeep fee for each booking to use it. The group can make all the important decisions...

There you have a quality item which works well and the ability to roast larger batches- but with real control and at a much higher quality level than a cobbled up home roaster.

Memberships can be purchased and sold. Casual use could also work once the user has trained (at a cost) in how to use the roaster safely. With a 5kg, you can easily roast a kilo.

This would be a terrific kick off for those who want to roast more or those who already have some "clients"

Just planting a seed- so to speak....

Awesome idea Chris
Shame I'm miles from anywhere!

But really interested in your almost throw-away line - do you think that a 5kg roaster is able to do justice to 1kg roasts? Not overkill? I always thought you'd need to get at least 3-4kg in to roast efficiently - which is a lot of coffee if you're only roasting for 3-4 people regularly. But if you can go smaller, then it would allow for room to expand over time… seems to make much more sense to get a bigger one to grow into rather than a small one to become an anchor around your neck when you expand!
