Abstract: The present disclosure relates to a juicer with improved juicing performance, and particularly, includes a motor housing, a drive part including a motor which is provided inside the motor housing, a connecting part which is formed with an inserting hole which is formed at one side of the motor housing and through which a rotary shaft penetrates, the rotary shaft transferring a driving force of the motor, a roller part which is detachably coupled to extend forward from the connecting part, and is provided therein to be rotatably driven by the driving force transferred from the drive part, and a hollow fastening guide which is formed in the inserting hole to improve a sealing force for the rotary shaft, thereby providing an advantage of greatly improving a juicing force of the juicer.

Abstract: The present disclosure relates to a juicer with improved juicing performance and a juicing method including the same, and particularly, includes a motor housing, a drive part including a motor which is provided inside the motor housing, and a roller part which is detachably coupled to extend forward from the motor housing, and is provided therein to be rotatably driven by a driving force which is transferred from the drive part, and a driving speed of the motor is adjusted by at least one of pressure, current, and voltage according to the type of a material to be juiced, thereby greatly improving the juicing performance of the juicer.

Abstract: The present disclosure relates to a juicer with improved safety, and particularly, includes a motor housing, a drive part including a motor which is provided inside the motor housing, and a roller part which is detachably coupled to extend forward from the motor housing, and is provided therein to be rotatably driven by the drive force transferred from the drive part, in which the drive part and the roller part are attached and detached by the normal and reverse rotation of the motor, thereby greatly improving safety of the juicer.

Abstract: A grinder-type juicer including an upper and lower plate which squeeze foodstuff while rotating. The upper plate has spiral-shaped guide grooves (or elongated guide lands), the lower plate has juice-squeezing grooves. The juice is squeezed by the oblique action between the two grooves when the upper and lower plates rotate relative to each other in opposite directions with the juice dropping under its own weight and the residue being discharged at the outer edge of the lower plate.

Abstract: A juice extractor comprising a grinding chamber provided with a pair of helical gears for crushing juice material and a compression chamber disposed beneath and communicated with the grinding chamber and provided with a pair of rotating spiral screws. The spiral ridges of the spiral screws have cut-outs which engage with annular ribs formed on the interior surface of the compression chamber so that the residue produced by the helical gears of the grinding chamber is pressed against the annular ribs by the curved surfaces of the spiral ridges of the rotating spiral screws, thus further squeezing out juice from the residue.

Abstract: A juicer or a juice extractor having a vertically-arranged grinding chamber and compression chamber. The material to be ground into juice is first ground in the grinding chamber and then compressed in the compression chamber by a pair of Archimedes' screws; and in this case, the direction of movement of the material in the compression chamber is designed so as to be opposite to that in the grinding chamber.
