Reasons and feasibility analysis of coffee beans drying in the sun

Coffee bean sun drying is a common method of processing coffee beans, which helps improve the flavor and quality of coffee. This method mainly involves drying coffee beans by exposing them to sunlight to remove moisture and promote internal chemical reactions. The following will discuss why sun drying is necessary and the feasibility analysis from two aspects.

First of all, why do you expose coffee beans to the sun? When freshly picked coffee cherries are peeled, they are surrounded by a sticky layer of pulp and husk. These outer layers need to be removed to get the final product - roasted coffee beans. Drying in the sun can speed up the process of rotting and shedding the pulp and husk. In addition, drying at high temperatures can kill bacteria and fungi that may exist on the surface or inside, ensuring that the final product is not contaminated.

Next, let's see if the drying process is feasible. First, you need to consider weather conditions: coffee beans can only be fully dried when the temperature is suitable and there is no rainfall. In addition, there needs to be enough sunlight for a long time and intensity. Therefore, the right geographical location is also the key to successful drying of coffee beans. In addition, air circulation and humidity control need to be considered. If the environment is too humid or poorly ventilated, the coffee beans may mold or deteriorate.

In summary, drying coffee beans under suitable weather conditions is a feasible and effective method. However, there are still some challenges and limitations in actual operation. First, it requires high weather conditions and geographical location; second, it requires a lot of manpower and material resources to ensure the smooth progress of the whole process; finally, it is necessary to pay attention to controlling the drying time to avoid over-drying and quality loss.
