Eth Nat Yirg Idido roasted yesterday. I dropped some off at a friends coffee shop. In a few days he will brew it and tell me what he thinks. We believe my roasts are better than what we buy.

Hottop or?

I'm new to this forum but I'd love your thoughts and opinions on my buying decision.

I have been roasting with the Freshroast SR500 for a few months and for the price I like it. However given me and my usage its not quite right.

Although I have not made up my mind I am leaning toward getting the Hottop KN-8828B-2K+. Here is why I am considering it:

* Prefer to roast about 250g per batch
* Needs to be relatively portable since I roast outside. i.e. I move it once per week. ~20lbs
* Data. Real time temperature. I know this can be added to the non + model or other roasters but that could easily be yet another DIY project that I will never finish
* Holds its value. Not planning on selling it but in case its necessary
* Durable and with good factory support

I was just curious what other roasters there are that might fit my needs. As far as I can tell there really isn't anything else or am I missing something?

Thanks.

Alex...

you are not missing anything. I have the same Hot Top but mine is not the K model, I have the 2+ it has the manual eject but not the thermocouple.
yours came out right after mine.

frankly, you can not go wrong with the Hot Top, it is a workhorse.

I have had 3 Hot Tops, sold my older model and upgraded to the next.

you can drop 300 grams into that baby and roast away...

the Quest is the only other I would put into the same category as the Hot Top but with the Hot Top you have the auto roast ability which really rocks...

funny you mention the Fresh Roast it was my first roaster back in 2002 that I fondly call the gift from hell.

went from there to here...

I have the Quest 3 as well and love them both but I do love the auto ability of the Hot Top.

you can not go wrong with the Hot Top roaster Alex.


let us know,

ginny

there are a few more coming out like the Bullet but so far they are not shipping.
it is a very cool looking machine which will cost a bit more but, hmmmm...

I've had a KN-8828B-2K+ for about 6 months now and have roasted 50 batches in that time.

It fits nicely in the kitchen cabinet, and is light enough for me to move without any problems.

The only minor problem that I have had with the roaster are with the temperature readings which read between 15 and 40 degrees low. However, the readings are consistent, and first crack always starts at a reported 360 degrees (give or take 2 degrees). OK, I've had a few other problems when controlling the roast with Artisan, but those have been caused by my incompetence, or the mouse pad on the computer incorrectly interpreting an attempt to move the pointer as a click.

Good luck,

Alan

The new plus model is a nice roaster.

I modified my older B model to ET/BT probes and never looked back.

I too roast outside on a dedicated cart. Roll it out, roast, roll it back inside.

Thank you all for the replies.

ginny, auto mode? Is that the feature that allows you to record a roast and then replay it?

turtle, that looks about my ideal setup on the cart... I'll have to give that some thought.

One other question I thought of. Does the Hottop make roasting back to back convenient? I assume chaff needs to be cleaned each batch but how annoying is it to do back to back? I'd be doing 2-3 batches at a time on occasion.

Thanks again.


Edit: Oh yeah I read about the Bullet which looks very cool. Maybe that can be next :)

You can use just about anything for a cart. My wife picked up this old "typing table/stand" on the side of the road (curb side mall as she calls it).

Stock (unmodified) hottop has a safety cool down control that does not allow back to back roasts. The roaster must cool down to a set temp before it will go into preheat mode and start again.

I never found this to be too much of an issue as there is always something to do like putting the roasted beans away, shutting down the roast profile and saving things. Getting the beans and roast log ready for the next roast

This usually takes as long or longer than the roaster takes to cool down if you lift the filter out and open the roaster up (remove chaff tray and take load chute cover off).

If you feel it is taking too long, there is a modification you can make that "fools" the safety into thinking the roaster has cooled down. That mod is covered in a post here on HRO.

I've modified mine but I find that I rarely need to use it as it really does take a little time after you finish cooling and putting the roast away every batch.

Alex,

yes you can save and do the exact roast again, I will look as I forget how many you can save at one time. I never save them...

back to back right away, no but I have never had an issue waiting for the machine to cool down to roast again.

ALex,

Contact me at Hottop USA. I am the USA/Canada, and to some extent, the English speaking world's Hottop customer service agent. I do not want to use this wonderful forum as a sales platform, but would be willing to answer all your questions. Besides working for Hottop, I have been roasting on Hottop roasters for longer than anyone in North America, many years before I went to work for them.

Life's too short to drink bad coffee.

Thanks again for the comments all. Randy I will be in touch.

I bought a used and a bit damaged HotTop p-2 off ebay for short money and ended up buying the upgrade kit to make it go to the B2K+. I am so happy I did. This roaster is amazing. Equally amazing is Randy's support via the HotTop US web site. Lots of detailed instructions for repair, upgrade etc and they are pretty responsive on the emails. I feel like there needs to be a forum just for roasting with the upgraded hottop as I have not been able to get good roasts since upgrading. I was too used to pressing a few buttons for a program and letting it run. Now all my beans taste bitter, and I am barely roasting into 2c. Anyone with the hottop 2k+ want to help me relearn roasting on this puppy.
You will not be disappointed with the hottop, but now I have a line out the door with all my friends wanting coffee I might have to buy a bigger roaster!!
 
Randy G
Are you using Artisan? If not, why not? Artisan makes this roaster an amazing piece of technology with wonderful control. The Alarms allow temperature-priority programming and it turns the Hottop into a whole 'nother machine.

I have a new profile that is working out really well! Am roasting lighter than I ever have and have come very close to what Scott Rao recommends in his book, "The coffee roaster's Companion." I am not sure just how close one can get in a small electric home roasting appliance compared to what Scott roasts on, but I am trying. I have a City+ that has a development phase of 20% roasting 275 grams. I could probably get a bit further towards 25% if i roasted a bit less, but these are the best roasts I have ever done in terms of cupping espresso. Also, I did a City roast of Colombian I used in the Behmor Brazen and it was smooth as silk.

We are not going to post profiles on Hottop USA because of the difficulty with varying voltages and such, but maybe I can work something out and place them in a zip file on my website if there is interest. It is still a work in progress, and I suppose it always will be, but I think it is worth sharing.

Thanks for the Feedback Randy. I too am working with columbian. I have Rao's book and am trying to work through it. If you have a profile, I would love to see it to compare.
When I had the P panel on it, I seem to remember Pre-heat to 165 degrees and drop the beans in. There was a gradual heating phase of a few bars, but I cant correlate that to actual temperatures now, which is the new readout.

Are you stepping up the element temp gradually?
Also when do you put on the fan and to what degree?
How do you run a previously done profile to control the HT?

I find I start with the element at 70-80%, get the ET to about 2.00, drop the beans, wait 2 min, hike it to 80-85, another 2, hike to 90, turn fan on 25%, 2 more min go to 100% hiking up fan more. I drop heat when beans get to about 330-345 BT which is around the time I see 1c, and sometimes I will drop the beans right as 2c
What am I doing wrong? Any suggestions?
Info is a double edged sword!!

This is my favorite HT /Colo profile. I like the batch I was using roasted on the lighter side as you can tell.

Notice I do little with the heater. Mostly fan to control the roast.

Charbucks: That is a long roast. Turtle's total roast time looks better.
Turtle's looks good but only has a 16% development time. Scott Rao states that every one of his best roasts were between 20 and 25% development time. Not written in stone, of course, but both of you might try a higher charge temperature to shorten the pre-first roast time, and thus make the development time longer in relation to it. Charbuck, you might want to try charge at around 300 or so and leave the heat at 100% until about 350BT after the TP. I left myself a note and will try to save a file with all my data that you can load and try.

These are just some thoughts based on what is currently working for me.

OK here you go, folks...
By downloading this files and/or using the enclosed data you accept all liability and responsibility for its use and release me from any and all liability, fault, claims, etc. Additionally, this is in no way affiliated nor approved by Hottop USA.

The ZIP files contains three files. A png of the roast, the Artisan alarm file for controlling the roaster, and the roast file itself intended to be loaded as a background. Note that the charge temp was a bit higher than I normally aim for. At these charge temps you need to keep an eye on the temperature because once you reach about 330-340 the temperature rises quickly. Aim for a charge temp of about 350 to 355.

Here is the file:

Randy, thanks for that. Of course I wouldn't hold you liable for any of the info you provide. You are helping out.
So Higher initial temp, got it. What about Fan? When do you turn on the fan, and how much? Whats the rule of thumb?
That roast I did this morning tasted horrible. Worst batch to date.
I somehow lost a whole row of control buttons on the artisan for some reason. Also how do you get the bottom set of graphs showing control set points to display?

So you go 100% power until 350 at which point do you just cut power completely and let the roast coast into 2c?
