GMarket advert for the Kaldi Wide is 50rpm. Based on subjective observation, I would confirm that it is within this range.

The motor is a DC motor powered by an external 12v power adaptor brick. If you need to control the rotational speed, wiring up a potentiometer should be easy and cheap, and since it uses a low DC voltage, not risky in any way.

Just noticed the unit comes with a digital thermometer these days! However, high probability you will install a couple of thermocouples to directly feed into your logging software.

i'll check on the motor specs and revert.
Are you thinking of building your own?

If you know the Ikawa then you know it's an elaborated pop corn popper roaster
If you're good with AutoCad/Sketchup and have acces to material and fabrication, makes more sense to hack/upgrade a popcorn roaster

I'm actually working on that but very very slow progress

That's why gas roasters exists haha. For cost purposes. Also for the ability to drop/raise quickly.

It's about 57sen per KWh at the highest band TNB rate right now, so 1200w x 20 minutes(1/3 of an hour) = 0.4KWh which works out to be 22.8 sen per roast or lower.

Batch sizes on a popcorn roaster is like 60 to at most 100g without mods so that's the catch
On large batches production roasters (2kg/5g etc), the gas vs electricity gap becomes way more obvious

14cm diameter  X 15cm length.

built and ymeng85; would you consider an infrared halogen heat source? Honestly, I'm fascinated about this and would love to test it out.

built and anyone else who is looking at stovetop drum roasters,

If the Kaldi Wide fits your bill, just to inform the best deal appears to be from Qoo10.my for RM2,549 less RM300 online coupon, bringing it to RM2,249.

Even ordering directly from GMarket is more expensive, as there is about an additional charges for delivery.

Fascinating! Regretfully, much of the literature on these models is in Chinese.

Is the RF200 for 200gm or 300gm?

Please keep the forum updated on your decision, and if you get the Rotate Fun, please let us know your experience using it.

U may want to consider this roaster, i am currently using it... i guess its the best bang for buck roaster rated for up to 350G, but the sweetspot seems to be 200 to 250G for me, Coupled with a USB thermo probe and you can get some serious results. with total coast less den $1000 RM

Its a perforated drum, which means its very sensitive to heat control and air flow management is not needed. So far have been loving it, the build quality is really top notch.

Just ordered the coffee roaster from Taobao!

Total cost about almost MYR 700 including shipping and tax (since I paid using MB2u, 1.5%)

I dunno how you *can* wait! From the specs, it's a great deal (although I'm still very satisfied with the Kaldi I got which cost more than twice as much!).
Seriously, doubtful there can be a massive price change for this type of product.

One question to those already using it: how do you drop/discharge the roast when done? For the Kaldi I remove the hopper unit then tilt the entire roaster. I used to remove the heat diffusion screen but burnt myself (twice!) so now just clear out the ash along with the chaff.

Congrats and have fun!, remember to wash it before using for the first time as instructed by the seller..

I thought seasoning a roaster was to roast a batch until totally hangus, to understand its "behaviour"/characteristics, eg. RoR based on different heat/airflow settings, 1C/2C temperatures.

It's green bean restocking time! Anyone want to join to do a group buy?

Yeah, I saw the notice by Taoabao about the delivery might be delayed or something.

Agreed. But for Taobao, I am not too worried since they have a good refund policy.

Just ordered the coffee roaster from Taobao!

I bought directly from Taobao using link given by rytopa.

No need to use EZbuy. Taobao can directly ship to Msia.

Btw, just a correction, I paid about MYR 612 total for the roaster including shipping.
