Twin gear juicer

A method for using a juicer for juicing a produce, comprising:

• providing a juicer having a first juicing gear and a second juicing gear, a first juicing gear including a first main body having a plurality of first teeth including a first top surface with a first exposed and continuous cavity formed on the first top surface of multiple teeth of the plurality of first teeth but not an entirety of the plurality of first teeth, and the first exposed and continuous cavity having a first leading edge, the first exposed and continuous cavity spanning the first top surface of the multiple teeth of the plurality of first teeth but not the entirety of the plurality of first teeth, the first exposed and continuous cavity having a first leading edge, the first exposed and continuous cavity spanning the first top surface of the multiple teeth of the plurality of first teeth but not the entirety of the plurality of first teeth, and a second juicing gear having a second main body having a plurality of second teeth including a second top surface with a second exposed and continuous cavity formed on the second top surface of multiple teeth of the plurality of second teeth but not an entirety of the plurality of second teeth, and the second exposed and continuous cavity having a second leading edge, the second exposed and continuous cavity spanning the second top surface of the multiple teeth of the plurality of second teeth but not the entirety of the plurality of second teeth, wherein the first main body of the first juicing gear includes a first grinding portion and a first screw portion, the first grinding portion having the plurality of first teeth including the first top surface with the first exposed and continuous cavity formed on the first top surface of the plurality of first teeth, the first screw portion having a first thread, wherein the second main body of the second juicing gear includes a second grinding portion and a second screw portion, the second grinding portion having the plurality of second teeth including the second top surface with the second exposed and continuous cavity formed on the second top surface of the plurality of second teeth, the second screw portion having a second thread, wherein the first leading edge of the first exposed and continuous cavity and the second leading edge of the second exposed cavity face each other to form a produce aperture and interlock to bite the portion of the produce from a remainder of the produce and the first teeth of the first main body and the second teeth of the second main body crush the portion of the produce, such that the portion of the produce is first bit and then crushed by only the first main body and the second main body, and wherein the produce aperture extends as a through hole through the first juicing gear and the second juicing gear from a top of the first juicing gear and the second juicing gear to the bottom of the first juicing gear and the second juicing gear when the first leading edge of the first exposed and continuous cavity and the second leading edge of the second exposed cavity face each other to form the produce aperture through hole;
• rotating the first juicing gear in a first direction and the second juicing gear in a second direction;
• disposing a portion of the produce into the first exposed and continuous cavity and the second exposed and continuous cavity periodically, as the first juicing gear rotates in the first direction and the second juicing gear rotates in the second direction;
• biting, by the first leading edge and the second leading edge, the portion of the produce from a remainder of the produce, as the first juicing gear rotates in the first direction and the second juicing gear rotates in the second direction;
• crushing, by the plurality of first teeth and the plurality of second teeth, at least one of the produce and the remainder of the produce, as the first juicing gear rotates in the first direction and the second juicing gear rotates in the second direction, thereby releasing juice from the produce.
