Coffee bean roasting technology sharing: dehydration drying section _ relationship between dehydration and firepower

Professional coffee knowledge exchange more coffee bean information please follow the coffee workshop (Wechat official account cafe_style)

Recently, I have been strengthening my basic skills! And the baking part is no exception!

The roaster I use is mainly based on direct fire baking, so I often encounter a lot of trouble in the early baking, after all, there are not many friends who use direct fire machine!

The topic being studied recently is dehydration, or drying process. In the roasting of coffee beans, this dehydration and drying is divided throughout the baking stage, and most of us choose to do a lot of dehydration and drying in the first part of the baking!

The amount of firepower after this time will affect the degree of dehydration and drying, but the question is, can dehydration and drying be done with a small amount of firepower? And can't the dehydrated and dried parts be done perfectly with a lot of firepower?

I've tried many ways!

The end result is that the part of dehydration and drying is not what we think is in the first stage, and it is not that changing the firepower in the first stage of baking can make the dehydration and drying complete, but in the whole baking process is dehydration and drying!

I once used the maximum fire before dehydration drying, after an explosion with the minimum heat, to complete a pot of baking in more than 5 minutes, before tasting the idea is that this pot of beans can drink?

However, it surprised everyone during the cup test. I originally wanted to say that there should be coffee with undercooked bean core, but on the contrary, it has a rich and layered taste, and the bean core part is also fully ripe.

On another occasion, in order to make the bean core ripe, the coffee was roasted and dried over a low heat, but the coffee was not only not ripe but also astringent!

So it's not just a big fire that makes dehydration incomplete, and it's not OK that dehydration is done over a small fire!

But in the process of baking, how do you prepare firepower to complete the whole stage of dehydration and drying process, so that the coffee can show the best flavor and the taste that the roaster wants to show?

There are wonders in the coffee world, remember! We are creators! Don't let habits and traditions make us lose the real fun of playing coffee!
