Coffee Bean Processing

Same as palm oil, our coffee bean products have been processed through long and delicate process started from harvesting into roasting-ready coffee bean product.

Fresh harvested coffee fruits must be processed right away to prevent chemical reactions deteriorating coffee quality. Harvested fruits are sorted based on strict criteria and when processed right it will produce high quality coffee.

In general, there are two different types to process coffee fruit into coffee bean; wet process and dry process.

Wet Process (Fully Wash Process)

Right after harvesting, coffee fruits will be sorted to separate dirt, defective fruits, and diseased fruits. The fruits are also sorted to separate red colored fruits with the yellow or green colored fruits. The slick red fruits are superior ones with better quality coffee bean. Other colored fruits will produce inferior quality coffee bean.

The bean is separated from the skin and pulp using mechanical scrubbing machine.

Two methods can be applied: by soaking the beans in fresh water or by piling up wet beans inside wooden or concrete tank and covered by continuously dampened gunny sack. In tropical environment, fermentation process will need between 12-36 hours to complete. Sticky sweet layer covering the bean is also the sign for fermentation process. The process is completed with the layer is completely removed.

Fermented HS coffee beans are dried using either sun dying or machine drying process. Sun drying process will take between 2-3 weeks to produce coffee beans with 16-17% water content. The ideal water content is 12% to ensure the bean has stable flavor and resistant to mold.

Parchment skin covering the beans will be removed after the beans reach 12% water content. Parchment skin removed with huller machine to produce green beans.

Final sorting is important to separate whole green beans with defective beans and impurities. Sorted green beans are packed and stored for distribution.

Dry Processing

Coffee fruits are sorted right after harvested to separate slick red colored fruits (superior fruits) from green or yellow colored fruits (inferior fruits), defective fruits, and diseased fruits. Superior fruits are chosen to ensure high quality coffee bean.

Sorted coffee fruits will be dried under the sun for at leas two weeks. This process will produce dried coffee fruits with 15% water content.

Huller machine is used to separate the beans from the pulp and remove the parchment skin from the beans.

Coffee beans will be sorted to remove excessive pulp, parchment, defective beans, and other impurities.
