Hey guys. Check this out.
Click Here (coffeecrafters.com)
This is a "small" batch roaster I've been doing some research into. But cannot find and reputable feedback from. The thing looks great! And pretty cheap. For someone who is looking to do a quick start-up and needs a space efficient low cost roaster, it seems like the tits. However I'm worried about the lack of real temperature regulation. With only two heating elements, and only on/off options. Do you think the profiles are going to be limited. Also, have you ever heard of a roaster using this thing? Let me know

Dan

Nice! At 2KW/pound the heaters at should be enough for 5 pounds. Looks like two cicuits are required:
1x - 50 amp 240V
1x - 20 amp 120V

I would prefer the RC be enclosed at the top and have a glass viewing window...

I like more up front information from a company then I get on their site but it does look like a very interesting roaster. A 2kg drum roaster is roughly $8-14k, under $4k for a 5lb machine is on the verge of being to good to be true.

Interesting that the coffee cup logo they use is also the same one that I picked up for my coffee labels, just a free generic google image.

It is also interesting that the PO Box and street address match a company called "Accrafab" which apparently does metal fabrication, but also prototyping and small manufacturing. Presumably the company is handling the manufacturing of the roaster for (presumably) the designer (whomever that is). The phone number for the roaster and Accrafab are different.

It is alarming that the estimated roast times are 4-8.5 minutes. That would be unacceptable. Hopefully you could slow that down with airflow and heater control, but for $4000 I'd expect a PID controller.

The payoff calculator is a bit of a joke, as it does not (apparently) consider electricity cost, labor cost, etc.

Roaster: Coffee Crafters Artisan V

The roast temperature was interesting to test. We did our thermal testing at Washington State University. The 1 lb. batches roast air goes up to 475 F. with one element running. That's with an ambient temperature of 72 F. (room temperature). We tested 4 different food thermometers against our PID control readout and the university thermal tester. The least accurate was the PID controller. We only had a J type and a K might have been different. It was reading 5 degrees lower. Placement of the thermocouple might have had something to do with it.

Roaster: Coffee Crafters Artisan V

We arrived at our price from a different direction. We decided up front how much profit margin we wanted and priced the roaster accordingly. The lead engineer and I spent a lot of time with materials and construction methods. I wanted to make sure anyone could work on it themselves with readily available parts. Using mass produced parts helped us keep our costs down. I've got flac from marketing people for not pricing it in relation with other roasters with the same production. Obviously we want to make money but one of our main goals was to offer a roaster at a very reasonable price for people wanting to move up from home roasting equipment.

I didn't actually design this unit to sell. I just wanted something more efficient for my roasting operation in Thailand. I made it easy to operate because my girls didn't speak english very well and I needed to instruct by pointing. The factory took an interest when I asked them to build me some bodies and it grew from there. I'm still looking forward to getting back home and back to roasting.

Roaster: Coffee Crafters Artisan V

We're located in the Accrafab factory. I've been roasting with the prototype for 4 years but the engineers and I have improved the design a lot from the prototype. It's been fun working with the folks here. This is their first product built to completion. They do a lot of high tech manufacturing of components for medical and aerospace. I saw some nascar dashboards on a rack downstairs. I think they've been around since 1975. I've had several models running with a PID controller. They have some photo's of the factory at accrafab.com. It's a beautiful factory. We decided not to put one on this model since the food thermometer was just as accurate and you can't roast unattended anyway. You do have to pay attention though. If you're not watching the machine will make a nice back draft roast.

This is the same element setup as Sivetz had in their 8 lb. roaster. The hopper will actually roast 8 lbs but the cooling pot only holds 5 lbs. 8 lbs. takes about 12 minutes.  It takes a 60 amp designated circuit for the roaster and the chaff system draws 16 amps at 110 volt. It can be switched to 220 volt.

For me, the PID controller/SSR is very useful in manual mode. I keep an eye on rate-of-rise and adjust as needed.
