According to the present invention, as well as vegetables of relatively low strength, foods such as meat and aquatic products containing bones having relatively high strength are finely crushed to increase the crushing efficiency and to prevent dehydration housing in the process of extracting the edible objects. The present invention relates to an improved juicer to allow juice to be made while being moved, and to allow the sludge to be discharged well while allowing the juice to be juiced once more. The present invention provides a first crushing means (10) and a first crushing means (10) having a pair of crushing members (12, 12 '') installed in the input passage (3) below the hopper (2) to be engaged and rotated by the drive motor (11) power. The dewatering housing 30 may further include a second crushing means 20 under the first crushing means 10 and has a crushing object moving hole 31 in communication with the lower portion of the input passage 3. Although the outer peripheral edges of both sides of the dehydration housing 30, a plurality of elongated round bar 32 is fixed at equal intervals in the circumferential direction is in communication with the crushed object moving hole 31 between the plurality of round bar (32) The dewatering housing 30 and the crushed object moving hole 31 to be provided with a plurality of long dehydration passage 33 in the longitudinal direction, or to be provided with a plurality of long dehydration passage 33 in the longitudinal direction by drilling the dewatering housing 30 itself. ) Is a pair of screws that are inserted into the drive motor 41 to be engaged by the power (rotated) 42, 42 ''of the rotating shaft portion 43 toward the discharge hole 34, the diameter increases as the spiral screw piece 44 includes a crushing object compression moving means 40 is formed to narrow the pitch interval, Dewatering and combined sludge discharge means 50 having a dewatering rotary cylinder 53 on the outside of the discharge screw 51 tow
