The present invention relates to a coffee roasting apparatus using continuous-type microwave heating. The coffee roasting apparatus using continuous-type microwave heating comprises a microwave generation device and a microwave output control unit capable of controlling an output of microwaves of the microwave generation device. To prevent a cooling effect caused by external air when fresh beans are heated by microwave, a hot wind system which creates an air flow of external air around the fresh beans into the hot wind is installed. The coffee roasting apparatus using continuous-type microwave heating unit has a transfer device for continuously supplying and roasting fresh coffee beans and then inducing the fresh coffee beans to be discharged. Since insertion and extraction of the fresh beans are continuously performed in a roasting chamber (a heating chamber, a resonance cavity), an entrance and an exit should be open. Accordingly, a closing device for preventing electric waves from leaking is installed on the open portions. The coffee roasting apparatus using continuous-type microwave heating has a roasting apparatus operation unit capable of controlling the overall operation of the microwave continuous-type roasting apparatus. According to a coffee roasting control method using the microwave heating of the present invention, the roasting time (roasting duration time), temperature of the flow of external air (hot wind) for achieving a target roasting step, and appropriate microwave output corresponding to the same are calculated by using physical properties data of fresh coffee beans, which are pre-memorized in a microcomputer or a PLC, and operation information of coffee roasting input by an input unit, and roasting is finished by inserting microwave energy by continuously operating a magnetron.본 발명은 커피 생두 로스팅의 주 열원으로 사용하고자 하는 마이크로파 발생장치와, 마이크로파 발생장치의 마이크로파 출력을 제어할 수 있는 마이크로파 출력 제어부를 구비하고, 마이크로파로 인한 생두의 가열에 있어서 외기로 인한 냉각의 효과를 방지하고자 생두 주변의 외기 공기유동을 열풍으로 구성하는 열풍시스템
