Apparatus for extracting juice

PURPOSE: A juice extractor is provided to enhance juice efficiency since a juice screw revolves to one direction and a rotation juice extracting net revolves to the opposite direction while interlocking with the juice screw. CONSTITUTION: A juice extractor comprise a juice screw(150), a cylindrical rotation juice extracting net(200), a first cleaner(220), an exhaust guide(250), and a juice extracting case(300). The juice screw includes a sun gear(152) in the lower portion and a screw wing(151). The cylindrical rotation juice extracting net has a perforated net(202) and a ring gear(203). The perforated screen filters sludge and passes juice. The first cleaner is arranged in the outer circumference of the rotation juice extracting net and includes a cleaner rubber(221) and a stopping protrusion(223). The stopping protrusion is projected to the outside to stop rotation. The exhaust guide discharges extracted sludge and includes a planetary gear(251). The planetary gear transfers the torque of the juice screw to the rotation juice extracting net. The juice case includes a juice outlet(301) and a sludge outlet(302).
