Sun treatment, also known as drying, is the oldest method of raw bean treatment. as you can see from the picture, this method is the simplest and has only three parts in the real sense. The first step is to pick out the unripe beans after picking the coffee beans, and the second step is to accept the explosion of the sun directly in the open air, and then put it in the bucket for one to two months, so that the flavor of coffee beans is more complete and stable, and the third part uses a sheller to remove the shell. Finally, put it in a sack. Generally speaking, a sack is divided into 30kg and 60kg. Sun treatment will have more tropical fruit flavor, such as strawberry, sometimes with some fermented flavor, many people will think that the fermentation taste is not good, is a negative taste.

Sun drying treatment

Sun drying is the most traditional treatment. The fruits are naturally dried after harvest. The steps are as follows:

1. After harvest, coffee farmers directly put them in the sun field and dry them in the sun.

2. Timely turning and stirring is needed in the process of sun exposure to avoid uneven drying or fermentation.

3. Dry after a few days

4. Remove the pulp and peel of the dried raw beans with a shelling machine, and take out the raw beans.

Advantages: the pectin of the coffee fruit treated by the sun treatment retains its pectin, while the pectin itself is sweet, and during the sun exposure, the sugar will be transformed into the coffee beans, so the treated coffee will be relatively sweet, rich in taste and layered.

Disadvantages: there will be more defective beans, the appearance of beans is not uniform, it is easy to absorb the peculiar smell and soil smell on the surface.
