Acacia is prepped for export at Tracon Trading’s coffee cleaning and storage plant on 30,000 sq meters of land in Addis Ababa. The plant is equipped with modern Pinhalense coffee processing machines and a Buhler Z+ color sorter. The machine has the capacity of processing six tons per hour. All the processing jobs are mechanical and electronic including final hand picking on conveyor belts. The six storage silos of the plant have a capacity of accommodating about 15,000 metric tons of coffee at a time. The warehouses are clean, with ample lighting and ventilation, which are very ideal for keeping the quality of the coffee.
This coffee was decaffeinated using the Swiss Water process, which which follows several steps. Coffee is cleaned of the silver skin and transferred to tanks where it is soaked in clean water. During this pre-soak stage, coffee beans expand by 100%, preparing them for caffeine extraction. In the third step, low-caffeine green coffee extract (water saturated with soluble green coffee compounds) flows into the coffee tanks, beginning the counter-current extraction process. The green coffee extract has caffeine levels just below that of the green coffee. By adjusting time, temperature, and flow the process migrates the caffeine from the coffee into the green coffee extract. This process is repeated several times as the percentage of caffeine in the green coffee decreases.
