The present invention relates to a high-capacity juicing machine including: a base (210); a first support (230) and a second support (250) which are provided on the base (210) and are spaced from each other in a longitudinal direction; a first juicing member (270) having a first support shaft (275) rotatably provided on the first support (230) and an outer hollow rotor (271) which is positioned between the first support (230) and the second support (250), which is opened toward the second support (250), which is provided with a plurality of discharge holes (2711), and which is coupled to the first support shaft (275) to rotate together with the first support shaft; a second juicing member (290) having a second support shaft (293) rotatably provided on the second support (250) to be eccentric from the first support shaft (275), and an inner rotor (291) which is eccentrically positioned inside the first juicing member (270), and which is coupled to the second support shaft (293) to rotate together with the second support shaft; a first driving member (240) for driving the first support shaft (275); and a second driving member (260) for driving the second support shaft (293). The high-capacity juicing machine has a simple structure to be easily fabricated. Circumferential velocities of the first and second juicing members are controlled separately such that circumferential velocities of the first and second juicing members can be easily adjusted easily. The high-capacity juicing machine has an improved juicing performance.
