It has been discussed in HB.


I’m a little bit skeptical.  Assuming 115V, 15A, the electric heater could only provide ~1800W of heat, no matter what kind of proprietary-patent-pending heating element they use.  IDK, unless it has superior insulation layer, and demonstrates an efficient fan (to remove the heat).   :D

Post by: Ascholten on February 05, 2015, 02:57:52 PM
IF they kept the heat in, most the machines 'vent' a lot of it away to get rid of smoke etc,  the venting is constant, smoke or not.  Now if they kind of like your turkey oven, kept the heat in, then Id say its very possible because you don't have to keep replacing the heat lost during air changes.  Granted there will be a bit lost thru the sides etc etc.   Once it gets going, hits crack etc then start venting to get rid of smoke etc but I can see this being very doable.

It is a very pretty 1Kg roaster with a 3Kg per day recommended capacity limit. Or was that a typo error?

That looks quite impressive. It will be built with all industrial type parts in it. The owner said he didn't want a roaster to last for just a few years.

2 kilos of roaster beans per batch and capable of roasting 3 batches a day; that is not too bad at all. Plugs into a 120 volt socket. has heat and fan adjustments, has built-in compensation for voltage changes, it connects to a PC with a usb port and you can control the roasting with computer software if you choose. All this for 1500-2000 US dollars.

Sounds like if this is ever released it could go to the front of the goto line for home roasters.

I'd be bummed about the 3 batches per day part.  That would infer it needs to cool down between roasts, and that's no fun.

I have been using my HT-P for about 10 years, now, with very little complaints, but I would be interested in trying something with a bit more control.  I really like the look of the prototype, and it looks like you can have as much or little automation as you like.  No need to choose between manual or program models.  I will be watching.  One thing I did not see in the YT introduction, though, was ventilation.  Where does all the smoke go?

We don’t know how fast it runs for back to back roasting.  If you want to sell small amounts, you have to consider your hourly wage, and your theoretical maximum daily income.    ;)

Yeah I've been working the numbers. I don't mind the hours at the market, it'll be the closest to time off from my other businesses I get but time roasting that could be avoided is another thing.

Post by: 9Sbeans on February 12, 2015, 09:14:37 PM
It is a nice looking machine.  You may bring it to the farmer’s market and roast couple batches while waiting for customers.  This show piece should attract many people. 

However, if you buy decent green beans @ $6.5 per pound, with 15% weight loss, sell roasted @ $16 per pound, you will earn ~$15.5 per 1-kg load.  Besides, you will need a power generator.  It’s a big toy, a lot of fun, but not efficient.  I may get a TJ-067 (or some other bigger boys) at home to do the major roasting job, and show off the Aillio in the market as small batches demos.   :P

From that forum:

To Whom it May Concern,

I noticed on the technical specs in your brochure that the "Daily Capacity" was 3 kg. That is only 3 full roasts per day. Why the limit on roasting more? Is that a mistake and you really mean "Hourly capacity?

Thanks,

Nate H

~~~~~~~~~~~~~~

Hi Nate

The reason we write 3KG is because we don't want to advertise the roaster as a 24/7 continuous commercial machine. It was not designed like this.
You can of course roast as much as you like, but some components might have to be replaced pre-maturely. Drum motor, belt, and exhaust fan motor comes to mind.
Nothing is going to overheat or fail if you roast continuously though.

Hope this helps.

Title: Re: New 1 kg Roaster Alternative
Post by: mcmasterp on February 18, 2015, 01:40:21 PM
Well it's not necessarily that depressing. The key would be to get some of the people who buy coffee from you to repurchase on a regular basis. If you sell 10 lbs of coffee at a farm market in 6 hours and 1 of those people order more from say your website etc. After one season you'll be selling 25 lb a week before even going to farmers market.

Time costs are the biggest deal. But for me the fun is always in having a hobby that generates money instead of costing it. I also build websites, 3d print, cnc mill so making this one profitable or even break even is great.

Post by: whattodo on February 19, 2015, 08:40:26 PM
I have received answers against my questions from Aillio.

1. Why there is 3kg daily roasting limit? Is back to back roasting not allowed?

The reason we write 3KG is because we don't want to advertise the roaster as a 24/7 continuous commercial machine. It was not designed like this.
What I mean is that the drum motor, belt, and exhaust fan motor have a calculated lifespan, and might fail earlier than what we calculated.

You can of course roast as much as you like, nothing is going to overheat or fail if you roast continuously, and there are many safety features in place to help monitor the roaster.
With the Bullet you start roasting when you reach the desired drum temperature, and typically the drum temp will be higher at the end of the roast, so you will have to wait for it to come down a bit before starting your new batch. You can cool off the drum with the exhaust fan.

Another reason is you need to empty the chaff collector every 2-3 kg, so if you plan on roasting 10 kg / day its not designed to do this.

2. How do you handle smoke and chaff during roasting?

The back of the roaster contains a chaff collector with a filter.
The smoke exits the roaster from the back, and upwards, so you can place it under your kitchen smoke hood.

So I don't have to roast in my exhausting roasting station in my dungeon(basement)? sounds good to me! Now I'm glad I insisted on having an outside exhausting stove vent instead of those bs recirculating jimjams

Rotate Fun is very popular in Taiwan because it’s cheap, and a first time roaster can easily perceive the changes of sensory cues (color, smell, and sound).  However, I wouldn’t recommend it.
 
As can be seen in the video clip, there are always some beans exposed to the wide open, cooling.  I expect these beans will experience extreme hot->cold->hot temperature fluctuation.  In addition, this wide opening also renders the fan control ineffective.  IIRC, the stock design does not include the variable speed ventilation fan, and I have seen its users trying to install different types of fans or even cyclones.  However, even with the aid of a user-installed fan, the cold air will be directly brought into the chamber through the opening, no preheating route. 

IMO, the Rotate Fun cannot provide stable heat/fan adjustments, and a serious beginner will quickly outgrow it.   :)

Post by: 9Sbeans on February 25, 2015, 01:48:11 PM
I would say that the Rotate Fun 300 still has its merit as an entry level roaster.   :P  When compared to a skillet pan on a stove-top, or a heat gun-dog bowl approach, Rotate Fun 300 can easily handle more beans and the drum does mix those beans well.  At its simplest configuration, including one thermometer, RF300 is about US$230.  At this price range, it is appealing even compared to a well-equipped popper.   

The bigger brother, RF1200 is much more expensive though.  Huky 500 is a strong contender at this price range and, IMHO, I don’t see RF1200 hold ground.  The skill set developed on a Huky might be still useful when upgrading to a bigger gas-drum roaster.  On the other hand, the air flow of the RF1200 could be so distinctive that its roasting characteristics won’t be easily transferable.

I am sorry for being a skeptic, but, I cannot see a 110V machine being able to do 1kg anywhere close to what would look like a 'normal profile'. The 220V maybe with 3500 watts or so, but not 110 unless you have to run it on a 110v 40amp circuit - nothing a normal home would have available.  This was my problem which caused me to have to upgrade my home built machine from 1500 watts to 3000 watts. And at 3000 watts I get about 700 grams beans to 440F in about 11:00 at 80% power - which gives me some room to wiggle around at the higher temps. I think this machine would take many, many, minutes longer to reach 1st crack if it could at all at that volume.  Even using 100% re-circulation of exhaust air. 

Again sorry for the pessimism. It's just that I spent a lot of time and effort designing my roaster and have a good idea about what these machines require for power. Maybe I will be proven wrong :o

Just watched the video posted on you tube. It was an 800g roast. Do not know what machine it was 110V or 220V (my guess the 220V), but at 12 minutes they were still a good 20 degrees away from first crack and not until 14 minutes were they getting around 1st crack at 405F. And that is where he dropped the roast.  That sure seems like a long roast with a low temperature drop to me!

Just guessing, but Scandinavian roasts tend to be very light. Perhaps they are designing the machine to satisfy Scandinavian tastes. When I first received my Italian made V.B.M., it was set at 11 bars. The factory rep. said, "We Europeans [Italians] like stronger coffee."
Title: Re: New 1 kg Roaster Alternative
Post by: peter on April 12, 2015, 05:43:45 PM
hat hink the roaster's capacity is based on the fact that it uses an induction heating system, which is supposedly much more efficient then a typical resistance-based heating element. I don't know much about these things, but I think our typical conception of what an electrical roaster can do he is different than what this roaster uses.

Well the bullet is a modern looking machine.... I met the twin brothers that invented and are bringing this machine to market. It will be available this summer and imports from Taiwan.

My initial thoughts are that like Peter I'd like to see how induction heating goes? No sight glass...., hard to clean and must be taken apart..... power? It can only do three batches a day. It has a small footprint, good looking but not traditional, and low energy needs.

I'll grab the spec sheet and gather my thoughts and post more later.

Whattodo, When I look at the plots in the link you provided, it appears they are saying 1st Crack occurs at aprox 383F  that sure seems low to me as I always see this occur between 401 and 411F - maybe the bean temp thermocoupler on  their unit is off by 20 degrees? I wonder this because it carries through to their 2nd crack which they say is at 428F. That appears to be about 20 degrees low as well.

  This is where my build is also listed - my first generation build that is. My current generation 3 roaster build is now using a 3000 watt heating element to give me a larger load and is using Artisan for profiling. Here is the 1st gen link if you like: 

I am not saying that it is impossible to get a 1kg load in 12-13 minutes at +/- 440 in 12 minutes with enough insulation and recirculation but  it sure is hard for me to believe - especially at 1550 watts.  Further, when you look at the temps where they are saying the major markers such as 1st C  and 2nd C occur I wonder why they are so far off of what is considered normal. 

Peter may be right that induction may be the difference - I am anxious to see more roast profiles and reviews from a neutral party.

Just watched the video posted on you tube. It was an 800g roast. Do not know what machine it was 110V or 220V (my guess the 220V), but at 12 minutes they were still a good 20 degrees away from first crack and not until 14 minutes were they getting around 1st crack at 405F. And that is where he dropped the roast.  That sure seems like a long roast with a low temperature drop to me!
I have been reading about the higher powered roasters, and it seems best to use 220v.

Silly question - is there a simple (and low $$$) way to get 220v in a typical USA home that is wired for 120v? I already use a variac to improve the power for my Hottop roaster (from 116v to 121v at the outlet).

You already get 240v or just shy of it. You can run a new wire from the breaker box and tap into the additional voltage by using a 240v breaker.

I had to do this for my espresso machine last year and it was far easier than I was expecting.

Nearly every residential service panel in the US has two 120-volt wires and one neutral wire running to it from the utility company. Each wire powers one “bus” (copper vertical leg) inside the main service panel. That’s why you usually see two columns of breakers (or fuses) when you open your service panel door. The common 120-volt circuits that power everything from your lava lamp to your vacuum cleaner are powered from one of those two buses. The standard 15- or 20-amp circuit breakers work by clipping onto one of the buses. Then the circuit’s hot (red or black) feed wire is clamped to the circuit breaker, while the neutral (white) wire and bare copper ground wire are clamped to the common neutral bar.

The way you get a 240-volt circuit is simple. A “double-pole” circuit breaker is clipped into both 120 buses at the same time, so the voltage to the circuit is doubled. That’s why 240-volt circuits need two hot wires and a neutral to carry the electricity to the appliance, plus a ground wire.

With a 240V circuit  the 2 120V legs are cycling opposite each other at 60htz in the US.  The wiring to a receptacle and the receptacle itself requires special wiring considerations to be in code compliance.

I am not very hardware-savvy, so I would definitely use an electrician. Thank you for the detailed explanation!

There is no neutral in a 240 circuit, only two conductors and a ground.

As was mentioned above, there are additional considerations for safety and code compliance.

You'll get 4 wires out of a typical US 240V appliance though, and one of them is more neutral than ground, the other is more ground than neutral.  Web search will turn up thousands of questions and attempted answers for this issue.  I like propane.

The plug on an electric range or dryer only has three prongs on it.

Any news on he Bullet?  My HT control board is getting mighty flaky, and I may soon have a need (read: excuse) to find a replacement.  (No, don't tell me how easy it is to replace the board!)

I looked the bullet over with great detail out in Seattle at the SCAA. It will be good to get a hands on feedback from a member here. Good luck!  Jim

I'm interested as well. It looks interestingly different. I like that it doesn't resemble a miniature commercial roaster. However I am not sure why the Probat Sample roaster design hasn't been made bigger, I think that would be an interesting concept.

Congrats!!!!  Completely jealous. I wanted to pre-order one as well, but the wife thought I was going a little nuts on coffee supplies lately (maybe she's right  :-X) 

Please let us know your thoughts as you start to use it. 

Good luck and happy roasting

Nice article. thanks for sharing!

When I saw the roaster last spring at SCAA in Seattle one of my concerns was tear down and cleaning.....? It will be nice to see later reviews after the roaster has been used for a longer period of time and someone has gotten into the guts for cleaning....

All in all is looks like there might be a nice new alternative for home roasters!?

If I were to preorder one, do you think there would be a roasting advantage in ordering it for 220v instead of 120v?

So, do you intend to hardwire it, or put a special plug on it?
Title: Re: New 1 kg Roaster Alternative_Bullet R1
Post by: kelppaddy on January 05, 2016, 03:01:16 PM
Running a dedicated 220v circuit and changing the plug to fit it if necessary would not be a problem.  After studying their site, I see now that there would be no advantage to choosing 220v over 120v AC.  The roaster is set to run at 1500 watts no matter if the voltage is 120v or 220v.  It will draw just under 7 amps if wired for 220v and just under 13 amps if wired for 120v.  It's the same amount of energy used, 1500 watts regardless of the input voltage it is wired for.

I just bit the bullet and placed my pre-order. ;D    I went with the 220v model as I read in another blog that the electronics run slightly cooler and the fan is a little quieter.
