This time, I will introduce one of our roasting tools, a portable gas stove.
【Manual roasting machine in use】
Before introducing the roasting tools,
The roasting machine I use for home roasting is a Union sample roaster
I have other articles about this roasting machine,
If you are interested, please check them out as well.
【Gas stove environment for roasting】
Portable stove for roasting, not kitchen stove
The sample roaster also comes with a pedestal,
It is possible to use it on a kitchen stove.
However, I don’t use a kitchen stove for three reasons.
The detailed reasons are described in my previous article.
The three reasons are
- The kitchen stove has a function that automatically reduces the heat when it gets too hot.
- The size of the kitchen stove's stove pot and the roasting machine do not match.
- The handle of the roasting machine cannot be turned due to contact with the handle.
For these three reasons, I use a "portable gas stove" instead of a kitchen stove.
【The portable gas stove I use】
Here is the portable gas stove I use.
Iwatani Cassette Fu BO Plus
" Iwatani " is a very reliable manufacturer of portable stoves.
I use the one that boasts the highest heat power among Iwatani's products for roasting.
(4.1kW 3500kcal/h)
Having experienced the roasting process
I feel that there are several points at which the heat power needs to be adjusted
temperature changes, the type of beans being handled and the amount of beans to be roasted,
and the type of roasting machine used.
Please read my story as an example.
In my case, it is possible to roast at medium heat for about 5 minutes from the start of roasting.
However, after about 6 to 8 minutes, the same heat rate is not enough.
I have the impression that the rate of temperature rise will decrease.
If the heat power is adjusted in anticipation of a slow rise in temperature, it is possible to roast
the roasting process will proceed smoothly from the middle to the latter half of the roasting process.
After having such an experience,
The portable gas stove with extra heat power is more suitable for roasting.
I personally think that a portable gas stove with extra power will expand the range of roasting.
【Portable stove I used when I started roasting】
When I started roasting, I used a stove with a little less heat power.
(3kw, 2500kacl/h portable gas stove)
Of course, it is possible to roast on this gas stove as well.
However, the range in which the heat power can be adjusted would be reduced,
The roasting time may become longer depending on the limit value of the heat power,
This can also affect the flavor of the beans.
【Comparison of the heat power of the two portable stoves...】
Both stoves are set to maximum heat power.
It may not look like there is much difference in power and stability.
However, the actual power and stability are different.
The one with the highest heat power always has a constant and stable heat even at max.
On the other hand, the portable gas stove we used to use had a flickering flame when the heat was turned to maximum.
The flame is flickering and there is a subtle change in intensity.
The difference between the two is in the power and stability of the maximum heat.
for repeated roasting at high heat,
I think it may have some influence on the roasting process to maintain and repeat high fire power.
In this article, I have described the high heat portable stove that I use,
However, the roasting process and the beans required for roasting are different for each person.
Therefore, it is not necessary to use a high-performance gas stove.
It is quite possible to roast delicious beans
After repeated roasting, you will be able to determine the heat power that is best suited for your process.
If you want to expand the range of roasting, such as roasting at high heat in a short time, choose a gas stove with high heat.
If you want to expand the range of your roasting process, such as roasting with high heat in a short time, selecting a gas stove with high heat is one way to do so. Please consider it.
So, this was an introduction to portable gas stoves used for roasting.
I hope it will be of some help to you.
