Coffee roasting method

摘要

Coffee is produced by first suspending a bubbling bed thereof under conditions which avoid popping in a heated medium wherein the heating gas is present in excess of 10:1 gas to coffee, the gas being less than 630 DEG F., and thereafter exposing the coffee to a further charge of hot gas at a comparable gas to coffee ratio to complete the roast, the second charge of air being at a temperature equal to or less than the first charge. The roasted coffee which is produced has a roasted whole bean density of from 0.28 to 0.34 gms./cc. When the roasted whole beans are suitably ground, a roasted and ground coffee of 11 to 13.5 oz. per 1000 cc. is produced.
