COFFEE USING HIGH HUMIDITY HOT GAS AND ITS COFFEE PRODUCT

摘要

PROBLEM TO BE SOLVED: To solve the problem that requirements including the uniform roasting of coffee at a high temperature in a short time and the supply of air (oxygen) are necessary to satisfy demands where the extract of the intrinsic flavor of the coffee and the production of a new characteristic flavor by deep roasting or ultradeep roasting are required to expand the demands of the coffee. SOLUTION: This method for roasting the coffee comprises uniformly roasting the coffee with a high-humidity hot gas produced by spraying water on a burner from a high-pressure nozzle from an ordinary roasting state to an ultradeep roasting state in a short time under the control of temperature, humidity, gas volume, water volume and the like. Thereby, the intrinsic flavor of the coffee and a new characteristic flavor can be produced. COPYRIGHT: (C)2009,JPO&INPIT
