1. A vertical low-speed juice-extracting drum that separates juice and debris in a crushing and squeezing process of a juice-extracting target by a screw rotating inside, the vertical low-speed juice-extracting drum comprising:
an inner module formed as a hollow cylinder with an upper portion open to accommodate the screw, the crushing and squeezing process of the juice-extracting target by an interaction with the screw, the inner module further formed with a plurality of slits formed as penetration holes having both lateral sides, an upper surface, and a lower surface above the upper portion and a lower portion along an interior circumference; and
an outer module having an upper portion open to be detachably coupled to the inner module, and formed with a rib formed by protruding in a radially interior direction on an interior circumference and including a protrusion surface, an upper surface, and a lower surface,
wherein the rib of the outer module is inserted into the slit of the inner module when the outer module surrounds and combines the inner module and a fixed gap discharging juice extracted by the interaction of the screw with the inner module 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,
wherein a width of the fixed gap is formed such that debris is filtered during the squeezing of the crushing and squeezing process of the juice-extracting target, and
wherein the fixed gap is formed in a direction intersecting a screw blade.
