Further, a guide pin receiving hole (46) is formed in the lower end of the suspension support shaft (38), and the guide pin is set up from the center of the bottom surface of the punching net (25). By inserting and fitting into (28), it prevents horizontal rotation of the rotating blades (A) and other illegal operations, and allows the rotating blades (A) to be accurately aligned with the strainer (C).
It is designed to maintain a stable positioning state.

However, by lifting the suspension support shaft (38) of the rotary blade (A) against the urging force of the compression coil spring (45), the suspension support shaft (38) is connected to the punching net ( 25) Guide pin (28)
The strainer (C) can be pulled out from the cradle (23) forward and can be replaced.

The first blade plate (39) of the rotating blade (A)
Is formed from a stainless steel plate having a band width (height) (h) substantially corresponding to the constant depth (d) of the U-shaped cross-section punching net (25) in a circular arc shape in plan view, and has a base end thereof. The portion is fixed to the vicinity of the lower end of the suspension support shaft (38), while the tip of the protrusion extending from the remaining suspension support shaft (38) elastically contacts the circumferential surface (25a) of the punching net (25). It comes into contact.

Further, the plate surface of the first blade plate (39) is in an upright state substantially parallel to the circumferential surface (25a) of the punching net (25), and its arc is related to the rotation direction (P). The convex curved surface serves as a pressing surface (39a) of the food material and forms a front side in the traveling direction, and gradually presses the food material to the circumferential surface (25a) of the punching net (25) as the rotation progresses. I have. However, the lower edge (lower edge of the steel plate) of the pressing action surface (39a) is formed by a punching mesh (2).
A small gap is maintained with the bottom surface (25b) of 5). (4

Has the effect that it can be provided as a versatile and convenient back strainer.

That is, according to the above configuration of the present invention, the bottom of the strainer (C) is formed of a punching net (25) having a constant depth (d), and not only its bottom surface (25b) but also its circumferential surface. A large number of eye holes (25c) are also distributed in (25a). On the other hand, a suspension shaft (38) for suspending the rotating blade (A)
From the correlation with the punching net (25), the first blade plate (39) that presses the food material on its circumferential surface (25a) and the second blade plate that presses the food material on the bottom surface (25b). Two different types of blades (40) are integrally extended.

Further, the lower end of the hanging support shaft (38) is inserted from the center of the bottom surface of the punching net (25) into the guide pin (28) to be erected, so that the hanging shaft (38) is inserted into the punching net (25). The rotating blades (A) are maintained in an accurate and stable positioning state in which the rotating blades (A) do not perform lateral vibrations or other illegal operations, and the rotating blades (A) in this state are punched with the second blade plate (40). A push-down biasing force that constantly presses against the bottom surface (25b) of the net (25) is also applied.

Therefore, even if the food material has a fiber content such as skin or streaks, the fiber content is applied to the first and second blades with respect to the circumferential surface (25a) and the bottom surface (25b) of the punching net (25). By the pressing action of the plates (39) and (40),
It can be surely cut or crushed by itself, and there is no possibility that the fiber content is clogged in the eye holes (25c) or remains inside the strainer (C). It can be widely applied to the straining work of any food.

The punching net (25) forming the bottom of the strainer (C) has a circumferential surface (25a) having a constant depth (d).
Also, a large number of eye holes (25c) are provided, and the first blade plate (39) of the rotating blade (A) also presses the food material, so that a large amount of the food material is shortened as much as possible. There is also the effect that the straining can be completed efficiently in time. The effects described above can be further improved by adopting the configuration of claim 2.

Further, if the configuration of claim 3 is adopted,
The urging force of the compression coil spring (45) can be applied extremely rationally to the entire rotary blade (A), and the cleaning is facilitated by enclosing this in the hollow interior of the sheath shaft (41). And the effect of preventing interference with other objects.

If the configuration of claim 4 is adopted, the strainer (C) can be positioned and used in an accurate horizontal installation state due to the correlation with the rotating blade (A). Since it is also possible to pull out the arc receiving notch (30) of 23) forward, there is an effect that the convenience and efficiency of the straining work can be enhanced.
