Apparatus for extracting juice

A juice extracting apparatus comprising:

• an extracting case comprising a brush mounted on an inner surface thereof, a juice outlet and a sludge outlet communicating an internal space thereof with an outside;
• an extracting screw unit positioned in the internal space of the extracting case, the extracting screw unit comprising a screw shaft coupled to a drive shaft of a driving means at a lower end, a screw blade formed on an outer peripheral surface of the screw shaft, and a sun gear provided at the lower end of the screw shaft;
• a rotary extracting net unit in which the extracting screw unit is positioned, the rotary extracting net unit comprising a brush mounted on an outer peripheral surface of the rotary extracting net unit and making a contact with the inner surface of the extracting case, a mesh net facing the screw blade to filter sludge while allowing juice to pass therethrough, and a ring gear provided at a lower portion of the rotary extracting net unit;
• and
• a discharge guide unit positioned at the lower portion of the rotary extracting net unit, the discharge guide unit comprising planet gears engaged between the sun gear and the ring gear, and transmitting a rotational force of the extracting screw unit to the rotary extracting net unit,
• wherein the juice squeezed from a raw material injected while the extracting screw unit and the rotary extracting net unit rotate in opposite directions from each other is discharged through the juice outlet and the sludge is discharged to the outside through the sludge outlet.
