A popcorn making machine includes a case enclosing a roaster with a circulated hot airflow therein, causing raw corn to pop up, a feeding pipe having an upper aperture for feeding raw corn thereinto and a lower aperture, and a trap mounted within the case. The trap has an upper entrance for receiving raw corn and a lower exit for discharging thereof into the roaster. The upper entrance is coupled with the lower aperture. The trap includes a body, having inner walls, and at least two blades attached to the inner walls on opposite sides thereof, and inwardly declined. A lower blade is inwardly protruded from the inner wall, so that it partially covers the lower exit. The trap prevents blocking the feeding pipe by corn kernels that otherwise would be capable of getting into and blocking thereof, thereby enhancing the machine's reliability and maintainability. Preferable trap dimensions are provided. |
