The second finely chopped fruit (vegetable) mass is then completely ground by the first grinding blade 109 and the second grinding blade 116. That is, the fruit chunks secondarily cut by the cutting blades 110a and 110b are pulverized finely due to the difference in the rotational speeds of the fourth cutter 106 and the fifth cutter 114 and discharged into the octagonal filter 120. The pulverized fruit (vegetables) then fills the face of the helical screw 170 and the space of the octagonal filter 120, which is then juiced down by screw 170. The juiced juice is then introduced into the juice outlet 136 through the juice liquid outlet hole 128, and the juice residue left in the juice is introduced into the waste outlet 138 through the waste outlet hole 126. At this time, the debris does not escape through the juice liquid discharge hole 128 by the rib 130 and continues to descend. Next, the juice liquid is discharged to the outside through the outlet 136, and then the residue is discharged to the outside through the outlet 138. Here, the juice discharged through the juice outlet 136 is a complete liquid free of dregs and grains, and the dreg discharged through the dregs outlet 138 is pure dregs containing no juice at all.

As described above, the juice machine of the present invention can be pulverized while cutting the fruit or vegetable chunks in a macdol manner using two cutters, and thus can be pulverized regardless of the particle size of the fruit (vegetable) chunks. You can improve as much as you can.
