Power requirements of the Bullet roaster

Hi Jonas,

Will the bullet need a separate, higher current circuit for power...will it run on normal 115V/15A outlet?

Okay, so how will this compete with the North tj-067 electric?
Will it be less expensive? Or what?

Hi Oldgearhead.

This roaster will not compete with the North roaster. It is two completely different roasters for different targets.

But yes, it will be a lot less expensive, and you can plug it straight into your power socket.

Hi JackH

The Bullet will run on a normal 115V/15A outlet. It will also be available in 230V version

OGH:

I think, well for myself at any rate, the North tj-067 is way to big to drop on the kitchen counter or on my stove panel under the huge vent system I have; many are looking for that ability, great quality, total control on a smaller scale and much better price point.

looking again at the North tj-067, it is a totally different animal.

thanks,

ginny

I mentioned the North because it's load is also 1 Kg.

Gee I thought I was on the cutting edge with my 120V, 18 amp, 500 gram,
heat-reclaiming, fluid-bed roaster. But the bullet will do twice that size load
sitting on your counter-top and powered by US 120V/20A supply. Sorry I'm
very skeptical.

Will it complete my 1 Kg roast in 12 minutes?
Where does the chaff from DP coffee end up?

OGH;

I think tons-o-home roasters are always skeptical of the new kid on the block so to speak.

We have our tabletop roasters:

Hot Top
Quest 3
Gene Cafe, kinda

and that is about it, with a max of 9 ounces in the Hot Top. though I must admit I push both my Hot Top and Quest 3 beyond their "suggested" amounts at times and usually it's when I have a few extra beans in a bag and I just dump them in the roaster.

hard and fast rules simply do not compute to me at all...

that said OGH the addition of the new Bullet 1K tabletop home roaster is for me something to talk about since I am not a builder of roasters. While I love to tinker, take things apart and create something if I need to buying a roaster would be my choice.

I do believe that their are many, many who fit in my profile with wanting to buy a roaster.

I personally have not seen what Jonas and company are going to offer any place at all - we have limited 1/2 pounders or the much bigger 1K's that are all over the place now that are too big and way to expensive for most to want to pay for a roasting hobby to start out with...

I am excited about this roaster. Friends ask me all of the time about what roaster they should buy and I point them to the Quest 3 as a full manual or the Hot Top as a manual/auto machine. If they like to build things and have time I simply point them to HRO for all the best advise for multiple choices for building.


thank you for the great question ad thoughts, this is really something different for us in the roasting community.

Very cool looking roaster. It looks as if , if you could somehow swivel the control panel to fit inside the front panel perimeter when not in usr, the cooler could just clamp on the face, and make a neat package for storage or transport. I wonder.
Bad coffee prevails when good coffee roasters stand by and do nothing.

Hi oldgearhead

The roaster will max draw 1550W of power, so you can use it on your 15A circuit breaker.

If you go to my blog below, you can see we roaster 1kg in 12min. 20-30 seconds into second crack. For this, we were only using 1300W. The reason we can do this if because the drum is insulated, and that we are using a "patent pending" way to heat the drum.
It also depends on how hot your drum is when you dump the beans.

Okay, insulated roast chambers aren't new, but your claim to have 4x more capacity than the HotTop sure is. Your heating element must be inside the drum or if you have a patent for such an enormous increase in heating efficiency, why would you be interested in this very tiny market segment? Is your heating element inside the drum?

Woot! I can't wait to see your (prototype?) roaster in action! Any ETA?

Jonas,

What's the expected roast time to FC for a 1kg charge using 115V 15A?

In my experience with a Dalian Amazon 1000, a 1500W heater forces slow roasts for any charge larger than even 500g.

Its fine to be skeptical, so were we when we fired her up the first time.
We were hoping to be able to roast 800g in 15 min, so it was a nice surprise to see that she can do a bit more than this.

No, the heating is done directly on the drum, there is nothing except the vanes inside.

The video will be here in a few weeks.

To me, it sounds like a very efficient roaster design.

To say you can't roast 1KG unless you have XXXX watts does not take into account the design (drum, fluid bed, etc) and size of the roasting chamber and many other variables.

My 1200W KKTO roaster can do up to 800g. The design has a well insulated, double wall roasting chamber. Since I am out in the cold garage, I limit the load to 650g in the winter. During the summer, I could go to 800g.

I think it would be best to keep the power/roast time discussion here vs. The "welcome" thread.
The only way to increase capacity while limiting energy consumption is to increase transfer efficiency. Hmmmm. .....More convection?

Admin note: Moved all discussions that are off topic from the welcome thread to this thread.

Please... lets try to keep to the thread topic. If there are questions not covered, please start a new thread. I am guilty of this too.

Thanks JackH

There is nothing particularly special about the drum.
We keep the roast chamber size (the air outside the drum) to a minimum.

Jonas,
How much/does convection play a role in this machine?

Hi Scott

That?s a good and also tricky question to answer.
You might have to elaborate a bit on what exactly you mean.

I dont know the ratio between the 3 (convection, radiation, conduction) as I have no way to measure it.

The airflow is a little similar to the quest as the air enters from the back of the drum. The back is not open as on the quest thought.

I'll preface by saying I'm not a drum person.
The combination of solid drum and low energy requirments got me wondering if convection (from the rear) was the answer.

I'm an air-roaster. For me it's all convection. It's hard for me to get my head around energy transfer without it.
Cheers, -Scott

Hi Scott

No, there is not forced convection in the Bullet, its just a drum roaster with a fan as in the big roasters.

Saw the new video on YouTube for the Bullet last night. Looks like a nice compact roaster not much bigger than a Hottop. Anxious to see pricing and the complete package, including the cooling tray. I find myself often needing more capacity than the HT offers and a compact 2 kilo unit will fill the bill nicely. Especially if the price is between 2 and 3K (or less!). Awaiting the first production units for sale....

Just as an FYI to anyone interested in this roaster, Sweet Maria's in Oakland, California is now a distributor, and they bring them in on a batch made basis. According to their website, they should arrive sometime in early June. I just took a look at their website. I think that these will sell out fast.
