Do you remember what I told you yesterday about the decaffeinated coffee company? one way valve knows that the Swiss Water Corporation uses water, pressure and time to remove caffeine from coffee beans:
1.First remove the beans into the vibrating cleaner to remove the impurities.
2.Then the coffee beans start the "five story journey" through the pneumatic blue tube maze, moving at a speed of about 100 feet per second to the huge extractor.
3.In the extractor, caffeine can bubble up from coffee beans. Each extractor has many top machine automatic control valve is used, to ensure that the correct amount of caffeine can get rid of, and keep the flavor of coffee. In the extractor, coffee beans soaked in liquid extraction of special flavor, is made of synthetic material by hot water and from other raw coffee beans extract. Because there is no caffeine extract, caffeine in coffee beans will naturally dissolve it. This is the difference between the concentration is known as the driving force, let the coffee beans to extract caffeine. As long as the amount of caffeine extraction than coffee, caffeine will continue run out. In order to ensure that this difference, extract or stop using activated carbon filter to remove caffeine.
When 99.9% of the caffeine is removed, the coffee beans can be dried.
