How many days should coffee beans be dried? What is the key to roasting?

Drying and roasting coffee beans are one of the important steps in making delicious coffee. During this process, coffee beans undergo multiple treatments and adjustments to ensure their best flavor and taste. So, let's take a look at the drying time of coffee beans and the key factors of roasting.

First, let's talk about the drying process of coffee beans. After picking, the fresh coffee cherries are peeled off the outer skin and the coffee beans wrapped inside are exposed. These wet and sticky coffee beans need to be sunbathed to remove moisture and reach the proper degree of drying.

Usually, the most common and efficient method is to lay the wet coffee beans on a large platform for sunbathing. This process takes several days or even longer to complete. Fresh fruits will be placed when the sun rises every morning and collected in the afternoon before they are not completely dry or become wet due to rain damage.

Next, let’s turn to the key factors of roasting. Roasting is heating coffee beans to a specific temperature to stimulate their internal chemical reactions and give them their unique flavor and aroma. Here are a few key factors:

1. Temperature control: Temperature control is very important during the entire baking process. Different temperatures are required at different stages to achieve the desired flavor and taste.

2. Café roasting time: Each type of coffee bean has its own specific ideal roasting time range. Too long or too short a time will affect the quality of the final product.

3. Cooling: After finishing roasting, the coffee beans need to be cooled quickly to stop the internal reaction and stabilize the flavor. This can be done by placing them in a special cooler.

4. Fire power regulation: Fire power regulation is also very important to control the chemical changes produced during the whole process. Proper adjustment of the fire power can ensure uniform heating and avoid over- or under-heating.

In summary, drying coffee beans and correctly performing furnace operations are necessary and critical steps to making delicious coffee. By properly drying coffee beans and precisely controlling the temperature, time and fire during the roasting process, we can obtain coffee with the best flavor and taste. Such a cup of fragrant and intoxicating coffee will become the goal pursued by every coffee lover.
