Title:
METHOD OF ROASTING RAW COFFEE BEANS USING MICROWAVE HEATING
Document Type and Number:
WIPO Patent Application WO/2019/098506
Kind Code:
A1
Abstract:
The present invention provides a method for controlling the roasting of coffee using microwave heating, the method being characterized in that roasting is completed in a coffee roasting device by: using raw coffee bean physical property data, pre-stored in a microcomputer or PLC, and coffee roasting operation information, input through an input unit, to calculate a roasting time (roasting retention time), an external air flow (hot air) temperature, and an appropriate microwave output corresponding to the temperature to achieve the target roasting step; and continuously operating a magnetron to input microwave energy. The continuous coffee roasting device using microwave heating comprises a microwave generation device intended to be used as a main heat source for roasting raw coffee beans and a microwave output control unit capable of controlling the microwave output of the microwave generation device, a hot air system providing an external air flow around the raw beans as hot air to prevent a cooling effect from occurring due to the external air when heating the raw beans with microwaves is installed, a transfer device continuously supplying the raw coffee beans and inducing the discharge of the coffee beans following roasting is provided, a shielding device for preventing microwaves from leaking out through open portions as the inlet and outlet portions of the roasting chamber (heating chamber and resonant cavity) must be open due to the raw coffee beans continuously entering and exiting the roasting chamber is installed, and a roasting device operation unit capable of controlling the overall operation of the continuous microwave roasting device is included.
