Claims12
A juicer comprising a housing having a top portion with a raw material supplying mouth, a plurality of cutters, a support structure for said housing, a roll for pressing the raw material and a link means engaging the top portion for holding the roll within said housing;
- wherein
- said housing has a bowl shaped structure with an exhaust port disposed at an intermediate portion thereof for removal of draff after pressing of said raw material, and further with an opening disposed at the bottom portion thereof for removal of juice produced by said pressing of said raw material;
- said plurality of cutters are arranged in vertical length in an inner wall of said housing;
- said roll has a convex bowl shape corresponding to the inner shape of said housing and substantially fit within said housing, and further comprising spiral shaped top portion, spiral shaped intermediate portion and a bowl shaped bottom portion, said spirals having their threads running vertically, and said top spiral having a larger space between each thread than the intermediate spiral, said bottom portion including a projection at the bottom thereof, said projection fitting into said opening disposed at the bottom of said housing, and wherein said bottom portion and said projection have a plurality of vertical grooves therein and terminating toward the end of said projection whereby squeezed juice will flow by gravity through said vertical grooves and out of said opening of said housing;
- and wherein
- said roll is positioned with the portion between the intermediate spiral and the bottom portion being disposed adjacent said exhaust port, whereby said raw material is fed into said supplying mouth and by operating said roll, said raw material is pressed against said cutters first grossly by the upper spiral and then finely by the intermediate spiral, and then the resulting draff of said raw material is exhausted through said exhaust port and the resulting juice flows through said vertical grooves of said bottom portion and through said vertical grooves of said projection and through said opening at the bottom of said housing.
