Drying phase

There are numerous stages of coffee roasting, which we distinguish. The period of drying is one of them. We lay out the entire process for you.

Drying phase

The green beans must be dried before we begin the real roasting process because they have a relative humidity of 10%. Drum roasters are used in all PRECISION roasters. As a result, it takes the beans 6 to 8 minutes to finish drying.

The temperature of the beans

Since you don’t want to burn the beans throughout the drying process, controlling the roaster’s temperature is crucial at this point. The temperature of the beans will be close to 160 °C as this step transitions into the following.
