Operated now under a slightly new process: a. 1000 kg of coffee beans are loaded into the mixing tank at a time and the beans are 98.5 wt% coffee solids and 1.5 wt% caffeine. b. 90% of the caffeine in the raw beans is removed with the caffeine loaded solvent stream from the mixing tank. c. The rotary dryer removes 95 wt% of the remaining solvent in the decaffeinated coffee beans but does not remove any additional caffeine. d. 80% of the solvent fed to the mixing tank leaves in the caffeine loaded solvent stream.
