Coffee roasting experiment: taxiing experiment of non-embroidered steel inner pot of local cannon and cast iron inner pot of business machine

For professional baristas, please follow the coffee workshop (Wechat official account cafe_style)

[the storage temperature of the unembroidered steel inner pot of the local gun is different from that of the cast iron inner pot of the business machine]

Therefore, the temperature immediately drops as soon as the fire is closed. Although the beans themselves can still bake themselves, there is a difference in temperature.

1. One kilogram machine: the temperature is still rising in a straight line, the taxiing time is about 30 seconds, and some beans will accidentally slide to the second explosion.

The taste is sweeter than that of non-slippery, and the throat rhyme is longer, but the aroma of sipping into the nasal cavity is less obvious.

If you want to keep a little more fruit acid, turn off the fire in advance. I tried to turn off the fire as soon as it exploded, and slipped to the end of the explosion, and the result was quite amazing.

two。 Clay cannon baked 250g, without heat shield: it seems to be no different from slippery, but the flavor weakens a little.

3. Earth cannon plus heat shield: after the fire is turned off, the temperature drop is slightly smaller, and it is better to slide for more than one minute, but it will lose a lot of aroma.

4. When the earth cannon plus the heat shield is baked to the cut-off point, remove the heat shield, and the firepower becomes smaller, at this time the temperature will not drop, and the temperature will not rise much, so that you can get close to the results of the business machine, and increase the degree of caramelization of coffee beans without wearing off too much aroma.
