The purpose of the present invention is to provide a juice extractor. The juice extractor includes a container (20) which includes a juice extracting space unit inside and a juice outlet on one side; a juice extracting filter drum (40) which is arranged inside the juice extracting space unit of the container (20) and which includes a juice filtering-discharging unit connected to the juice extracting space unit of the container (20) on a wall and a sludge outlet (42) on one side of the wall; a lower screw (50) which is received inside the juice extracting filter drum (40) and fixed; and an upper screw (60) which is formed on the upper side of the lower screw (50) and rotated by a driving unit formed on a body (10). The upper screw (60) performs a primary pressing-grinding step of primarily pressing and grinding materials by lowering the material between the lower screw (50) and the inner circumference of the upper screw (60) while being relatively rotated around the lower screw (50) and a secondary pressing-grinding step of secondarily extracting juice and discharging the juice to the outside of the juice extracting filter drum (40) by moving the material upward the material between the outer circumference of the upper screw (60) and the inner circumference of the juice extracting filter drum (60). |
