A pair of substantially V-shaped protrusions 84 are formed in the upper grooves 83 at a predetermined angle (approximately 60 degrees in this embodiment) at the inner corner of the lid 61. By fitting, rotation is prevented between the lid 61 and the groove 8 at the lower end.
The protrusions 59 of the cylindrical portion 29b fit into the cylindrical portions 3 and 3, thereby preventing rotation between the cylindrical portion 29 and the separation tube 29.

A synthetic resin regulating plate 41 is integrally provided so as to protrude horizontally so as to cover the entire surface. The outer edge of the regulating plate 41 here is bent downward and is positioned outside the recutting blades 40 with a gap therebetween to form a hanging portion 41a facing the extending portions 42. The distance 11 between the lower end of the hanging portion 41a and the upper surface of the extending portion 42 is made shorter than the distance 12 between the upper end of the re-cutting blade 40 and the lower surface of the regulating plate 41.

Next, the operation of the above embodiment will be explained. Before liquid generation, the filter 30 is in an extended state as shown in FIG.
After engaging the protrusions 72, 72 at the starting end with the grooves 73, 73, it is installed in the cylindrical part 29b. Then, while compressing the filter 30, the lid 61 is attached to the cylindrical portion 29b.
The protrusions 62 are fitted into the large diameter portion 60 of the vertical groove 8.
6a... into the horizontal groove 86b and rotate the lid 61 clockwise when viewed from above to insert the protrusion 62... into the horizontal groove 86b.
It is connected to the cylindrical portion 29b by positioning it in the inner part of.... In this state, the filter 30 is contracted as shown in FIG. 3 to prevent it from popping out. Then, the inner surface of the lid 61 and the filter 30 are connected by the projections 82 on the upper end.
A gap 78 is maintained between the upper end surface 70, a gap 69 by the protrusions 81, and a gap 80 by the protrusions 82 at the lower end. At the same time, protrusion 59...
The lower end of the filter 30 is locked to the cylindrical portion 29b by engagement with the grooves 83 at the lower end, and the upper end of the filter 30 is locked by the engagement between the protrusions 84 and the grooves 83 at the upper end.
1, the filter 30 is prevented from rotating vertically.

Next, the container lid 21b is closed on the receiver 21a, and the clamp device 97 is rotated to engage the lid 21b, thereby completing the use liquid production preparation state. Then, by driving the electric motor, materials such as fruits and vegetables are introduced into the input tube 44 and pushed by the push rod 95. Then, the material is grated by the grater blade 39, but large materials such as skin that could not be grated and cut are cut into small pieces by the re-cutting blade 40,
The particles are blown outward in the horizontal direction through the gap between the filter 9a or the notch in the hanging portion 41a, and adhere to the inner periphery of the filter 30. This adhered cut material descends along the tapered surface 75a of the filter 30 and is separated into scraps and liquid, and the liquid flows through the gaps 80 and 69 and reaches the inner periphery of the cylindrical portion 29b. and protrusion 5
After moving upward through the flow gap 58 formed by 7..., it flows out of the separating cylinder 29 through the flow gaps 90, 91 between the lid 61 and the cylinder part 29b, and is received in the container 21a. . This liquid is transferred to the outlet 25
The water flows down from the water and is received by the cup 119.

On the other hand, the waste is sequentially accumulated from the inner lower end H of the filter 30 while being held down by the holding projection 41a. When the material is further cut, the material to be cut is also accumulated in the inner upper half of the filter 30, and the liquid separated from the material to be cut in the lower part of the horizontal part 61b of the lid 61 is in the gap 79-89-90-91. and 69-90
-91 and flows out of the separation cylinder 29. When the material is further cut and accumulated inside the diameter of the opening 93 of the lid 61, the scraps are discharged to the outside of the separation tube 29 by the protrusions 96.

In the above youth generation operation, the push rod 95
The material is pressed against the cutter 38 at the cutter 3
8 tilts together with the platform 29a. Due to this tilting, the re-cutting blades 40... try to cut the lower surface of the regulating plate 41, but the distance l1 between the lower end of the hanging part 41a of the regulating plate 41 and the upper surface of the extending part 42... 39 and the lower surface of the regulating plate 41, the synthetic resin regulating plate 41 is not cut.

Next, in order to perform a grating function such as grating radish or shaving ice, the cylindrical part 29b is separated from the base part 29a, only the base part 29a is connected to the connector 11, and the valve 25 is closed to drive the electric motor. Then, when the material is input from the input tube 44 in the same way as when producing youth, the material is grated by the grating blade 39 and stored in the receiver 21a.

It should be noted that the present invention is not limited to the above embodiments, and the structures of the separation tube 29 and the filter 30 can be modified in various ways. Further, the extending portions 42 of the cutter 38 may be formed by cutting and bending slightly inside the outer edge of the disc-shaped cutter to form a recutting blade, and the outside of this recutting blade may be used as the extending portion.

(F) Effects of the Invention According to the present invention configured as described above, the regulating plate is not cut by the re-cutting blade due to the tilting movement of the cutter, and damage to the product can be prevented and the product can be cut in place. performance can be maintained. Moreover, the above-mentioned damage can be prevented simply by providing the extending portion and setting the interval, and the effect obtained by simplifying the structure is great.
