Abstract: The present disclosure relates to juice extractor comprising a cutting part for cutting a material for juice extraction beforehand by rotation above a screw, wherein the cutting part is formed in a dual structure of a core body and an outer shell covering the outer side of the core body with a material different from the core body.

Abstract: The present invention relates to a mesh drum and a juice extractor including the same. The mesh drum according to the present invention includes: a mesh plate formed in a cylindrical hollow shape and is gradually reduced in diameter as it goes toward the bottom from the top, and having at least one mesh holes formed on a side wall thereof; at least one wall blades formed on an inner circumferential surface of the mesh plate in the longitudinal direction of the mesh drum in such a manner as to position in proximity to a feed screw rotating inside the mesh plate; and at least one grinding blades formed on the inner circumferential surface of a lower portion of the mesh plate. The juice extractor according to the present invention includes the mesh drum, a main body, a feed screw, a housing, and cover.

Abstract: An integrated wall-breaking machine and slow juicer structure includes a housing; a driving motor linked with a first output shaft is provided within the housing; the first output shaft is linked with a second output shaft via a single-stage or a multi-stage transmission mechanism; a one-way bearing is fixed on the first output shaft; when the first output shaft rotates in one of a clockwise direction and a counterclockwise direction, an outer ring of the one-way bearing rotates and the second output shaft rotates; and when the first output shaft rotates in the other direction, an inner ring of the one-way bearing rotates and the outer ring thereof is locked. The wall-breaking machine and the slow juicer are integrated. By replacing different cutters and by rotating the first output shaft clockwise or counterclockwise, the wall-breaking function or the juicing function is realized.

Abstract: A juice-extracting drum includes a screw rotating inside. An inner module includes a hollow cylinder with an upper portion having the screw. A plurality of slits are formed as penetration holes having both lateral sides, an upper surface, and a lower surface along an interior circumference. An outer module is detachably coupled to the inner module, and includes a rib protruding in a radially interior direction on an interior circumference. The rib is inserted into the slit of the inner module when the outer module surrounds and combines the inner module. A predetermined fixed gap discharging juice extracted by the screw is formed lengthily in an up and down direction between the lateral side of the slit of the inner module and a lateral side of the rib of the outer module. The fixed gap is formed in a direction intersecting the screw blade.

Abstract: A separable screw and a juice extractor using the same are disclosed. A separable screw according to an exemplary embodiment of the present invention may include a first module formed with slits by bars on an external circumferential side; and a second module formed with ribs inserted into the slit of the first module; wherein the first module and the second module are detachably coupled, and the rib is inserted into the slit and a gap is formed between the rib and the slit when the second module is inserted into and coupled with the first module.

Abstract: The present invention relates to a juice extractor. The juice extractor includes: a main body; a housing; a cover; a mesh drum; and a feed screw, wherein a rotary cutting member is provided below the feed screw so that the rotary cutting member is rotated together with the rotation of the feed screw, whereby when the rotary cutting member is rotated, the lower end surface of the rotary cutting member grazes the upper end surface of the draff descending hole while intersecting the upper end surface of the draff descending hole so as to perform a cutting operation.
