PURPOSE: A production method of a new coffee product is provided to mix instant coffee with finely ground roasted coffee bean.CONSTITUTION: Frozen roasted coffee beans are finely ground at 16-120°C below zero to obtain finely ground coffee bean. The temperature of the finely ground coffee bean is increased to room temperature. The finely ground coffee bean is mixed with instant coffee, and the mixture is ground. A storing process of the finely ground coffee bean in a sealed container is conducted before the temperature increasing step and the mixing and grinding step. The frozen roasted coffee beans are obtained by freezing roasted coffee beans using liquid nitrogen. The temperature of the finely ground coffee bean is increased to 5-25°C. The producing step of the finely ground coffee bean is conducted by using an extremely low temperature pulverizer with a rotor rotating in a speed of 4,000-10,000 rpm.COPYRIGHT KIPO 2013[Reference numerals] (AA) Inject roasted coffee (BB) Firstly store (CC) Pulverize (DD) Discharge outside a pulverizer (EE) Render the temperature of coffee to the room temperature (5-25°C) (FF) Finally discharge (GG) Inject liquid nitrogen (HH) Inject nitrogen gas본 발명은 냉동 볶은 커피콩을 극저온 분쇄기에서 영하 16℃ ~ 영하 120℃의 온도로 100㎛이하의 평균입자 크기로 분쇄하여 커피콩 미분쇄물을 만드는 단계, 커피콩 미분쇄물의 품온을 상온으로 올리는 품온 상승단계, 품온이 상승된 커피콩 미분쇄물을 인스턴트 커피와 혼합하는 두 원료 혼합단계를 포함하여 제조되는 향미가 개선된 커피 제품 및 그 제조 방법을 제공하며, 인스턴트 커피의 편리성은 유지하고 그 약점을 보완하여, 인스턴트 커피를 사용하여 원두 커피의 향을 싼 값으로 즐길 수 있게 되는 효과가 있다.
