All decaffeinators utilize the same steps to accomplish the extraction of caffeine from green coffee. The steps include Steaming, Hydration, Extraction and Drying. All of the steps are done in 3 primary pieces of equipment. First is the Pre-treatment tank, second is the Extractor and the last step is done in the Dryer. Each piece of equipment is designed to specifically achieve a desired result. The internal design differentiates the decaffeinated coffee processors.
