Detailed explanation of the procedures required for processing coffee beans

Coffee is a popular drink, and coffee beans are an important raw material for making coffee. Before coffee beans are transformed into a usable form, they need to go through a series of processing procedures. This article will detail the various steps required to process coffee beans.

Picking and harvesting

First of all, picking and harvesting is the first step to start the whole processing process. Usually, only coffee cherries that have reached a certain degree of maturity can be picked. This ensures the best taste and flavor.

Farmers manually or mechanically remove the ripe coffee cherries from the trees and carry out pre-processing operations such as sorting and washing.

Peeling and fermentation

Next, peeling is an important step. There are generally two ways to remove the pulp: dry method and wet method.

a. Dry method:

In the dry process, the whole fruit is exposed to the sun or in special equipment to dry the pulp. Once the pulp is completely dry, it can be removed mechanically.

b. Wet method:

In wet processing, coffee beans are soaked in water to ferment. This process helps remove the pulp and makes the inside of the coffee bean cleaner. Fermentation time and conditions will be determined on a case-by-case basis.

Drying and dehydration

After peeling and fermentation, the next steps are drying and dehydration.

In the dry process, coffee beans are dried in the sun or in special equipment. This process usually takes days or even weeks to complete.

The wet processed coffee beans need to be dehydrated by mechanical equipment. This ensures that the coffee beans reach the appropriate moisture content and avoids problems such as mold growth.

Baking

After the previous steps, the next step is the most critical and challenging part - baking.

Roasting is the process of heating coffee beans to a specific temperature to stimulate their internal chemical reactions and give them their unique flavor and aroma.

Different roasting degrees produce coffee with different tastes and flavors. From light roasting to dark roasting, each stage brings different characteristics.

Packaging and Shipping

The final step is to pack and ship the processed coffee beans.

Usually, coffee beans are packed into bags made of special materials and sealed to keep them fresh and prevent oxidation.

The bags are then shipped by ship, air or road to suppliers around the world or directly to consumers.

Conclusion

The above is a detailed explanation of the procedures required for processing coffee beans. From picking and harvesting to peeling and fermenting, drying and dehydrating to the most critical baking stage, each step has an important impact on the final taste and flavor. Only carefully processed coffee beans can produce satisfactory coffee.
