Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a food crushing and shredding apparatus such as a meat chopper, a miso manufacturing apparatus, and a soy sauce manufacturing apparatus for crushing and shredding meat, fish, cereals, beans, vegetables, and the like. Things.

2. Description of the Related Art Conventionally, as this type of food crushing and shredding device, a spiral shaft is provided in a casing, and a processing object supplied from a processing logistics inlet provided on one end upper surface of the casing is spirally wound to the other end of the casing. Feeding, crushing, pressing and chopping by a cutting blade provided at the other end of the casing and sending it out are known, but in this case, the workpiece to be supplied is not always limited to a strip, for example, Plates like stored and frozen products,
The block shape is not uniform in size, and the inlet needs to be made sufficiently large. In order for these to be caught in the feed spiral, the pitch of the feed spiral must be adjusted to the size of the inlet of the physical distribution to be processed, and the inflow amount must be constant, and the inflow must necessarily flow down to the feed spiral. However, in order to make the feed spiral particularly large in the range having a normal outer diameter, the angle of each spiral with the spiral axis, that is, the lead angle must be extremely large. That is, as shown in FIG. 5, the spiral mountains appearing one after another in the processing object inlet 6 'are positioned obliquely to the line connecting the front and rear edges of the processing object inlet 6'. The helical pitch for biting the object flowing into the inflow port must be larger than the size a 'of the processing object inlet while keeping the inflow amount of the object constant, but this is structurally difficult. Impossible. For this reason, actually, since the pitch of each spiral is made smaller than the inlet, the object to be treated is always divided into each spiral mountain that appears and moves in a plurality of rows in the inlet, and the inflow amount is not constant. An object to be processed that is larger than the spiral pitch is placed over each spiral mountain and does not flow down. Therefore, an auxiliary device or human power is required to feed the workpiece.

In such a case, in the conventional relationship between the inlet and the feed spiral, according to the magnitude of the processing capacity of the workpieces of various shapes, devices having various shapes and sizes having large and small inlets are manufactured. There was also the disadvantage of having to do it.

Problem to be Solved by the Invention The present invention relates to a conventional crushing and shredding device, in which a processing object supplied to a processing logistics inlet is not bitten smoothly, and it is appropriately pushed by human power, and a special auxiliary device is used. The additional press-fitting required additional work, which was time-consuming and could result in failure due to excessive work. It is an object of the present invention to provide an apparatus improved so that various shapes can be smoothly engaged without the need for the same.

Means for Solving the Problems The present inventor has conducted various studies on the food crushing and shredding apparatus, and has found that the spiral pitch is adjusted to the size of the to-be-processed logistics inlet, and the exposed spiral mountain below the to-be-processed logistics inlet is obtained. Of these, the lead angle of the spiral near the trailing end with respect to the feed direction is smaller than the lead angle of the other spirals, and in some cases, the portion corresponding to the exposed valley between the above spiral mountain and the next spiral mountain is processed. The present inventors have found that the above-mentioned object can be achieved by eccentrically forming the deepest valley so as to be located immediately below the material charging port, and completed the present invention.

That is, according to the present invention, the traveling direction of the workpiece is
When the opposite direction is set to the rear, a horizontal shaft formed spirally in the middle is supported in a horizontal cylindrical casing having a logistics inlet on the upper surface near the rear end, and a cutting blade and a cutting blade are provided at the front end of the casing. In a processing apparatus provided with a perforated lid plate, the rear end of the feed spiral is aligned immediately below the rear edge of the inlet of the target logistics, and the pitch of the spiral is equal to the dimensions before and after the inlet of the target logistics. Among the peaks, the lead angle of the first spiral mountain connected to the rear end is smaller than the lead angle of the other spiral mountains, and the shaft portion forming the valley between the first spiral mountain and the next spiral mountain is further reduced. When the first spiral mountain and the next spiral mountain are located just below the leading edge and the trailing edge, respectively, of the to-be-processed logistics inlet, eccentric with respect to the shaft portion between the other spiral mountains, and forming a cross section in an elliptical shape. The deepest valley There is provided a food crushing shredding apparatus characterized by being configured to so that.

The present invention is characterized by the structure of the spiral as described above, and the structure is capable of sending workpieces of various sizes and shapes. The processing capacity can be adjusted by the same casing only by changing the depth of the feed spiral.

In other words, if the feed spiral has a depth of 1/2 or 2 times, the capacity will be 1/2 or 2 times, and the rotation speed should be combined to 1/2 or 2 times. As a result, a wide processing capacity of 1/4 or 4 times can be exhibited.

In addition, although the diameter of the inlet of the conventional apparatus was limited when the round or square was selected due to the structure of the feed spiral, the feed spiral structure in the present invention was adopted. The length of the ellipse or rectangle in the axial direction of the inlet can be increased, and this method makes it possible to increase the inflow rate and the processing capacity by using casings of the same size.

That is, in the present invention, the inflow amount and the throughput can be doubled by doubling the axial length of the casing inflow port in the axial direction without changing the casing diameter.

 Next, the present invention will be described in detail with reference to examples.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a side sectional view of an apparatus of the present invention. In FIG. In a cylindrical container-shaped casing 1 having a front end opened, a horizontal shaft 2 formed in a spiral in the middle is supported by a rear end of the casing 1 at a rear end thereof, and a rotation slidable only in a lateral direction at a front end. A cutting blade 3 is fitted, a cover plate 5 having a processed material discharge hole 4 is fitted and attached to the front end of the casing 1, and
A processing object inlet 6 is formed on the upper surface near the rear end of the casing 1. The horizontal shaft 2 is rotated by a driving mechanism connected to the rear end of the casing 1, so that the object to be fed from the processing object inlet 6 is rotated. The processed material is squeezed and crushed through a feed spiral, and is shredded by the cutting blade 3.

Up to this point, the device is the same as the conventional device, but in the present invention, as described above, the portion existing between the spiral mountain at the rear end of the horizontal axis 2 in the moving direction of the workpiece and the next spiral mountain. However, it is characterized in that it is configured as shown in FIG. That is, of the spiral ridges erected on the horizontal shaft 2, the interval between the spiral ridge 7 connected to the rear end in the feeding direction and the next spiral ridge 8 is formed to be substantially equal to the width a of the processing target inlet 6. The angle α intersecting with a line perpendicular to the axis of the horizontal axis 2 of the spiral mountain 7 connected to the rear end, that is, the lead angle α is
The lead angles α ′ of the spiral mountains 8 after the second are smaller than the lead angles α ′. Further, the shaft portion 9 forming a valley between the spiral ridges 7 and 8 is eccentric with respect to the shaft portion 9 'between the other spiral ridges, and the cross section is formed in an oval shape as shown in the figure. When the spiral mountains 7, 8 are located immediately below the front and rear edges of the to-be-processed logistics inlet 6, it is more advantageous to make the valley deepest.

In addition, the present invention particularly provides the helical shape of the horizontal axis 2 with the second spiral.
The configuration as shown in the figure is advantageous because the processing object supplied to the processing distribution inlet 6 can be pushed more smoothly irrespective of its shape.

Operation FIG. 3 is a side sectional view showing the operation sequence of the present invention, and FIG. 4 is a plan view corresponding to the state. Referring to these figures, FIGS. 3 (A) to (E) and FIGS. 4 (A) to (E) each show that the horizontal axis 2 is 0 °.
This figure shows a state in which the valley is rotated by 45 ° until it makes a half turn, and the depth of the valley in FIGS. 3 (A) to 3 (E) is U,
Expressed as V, W, X, Y. Now, the feed helical pitch peaks in FIGS. 3 (A) and (B) and FIGS. 4 (A) and (B),
The object to be processed accompanying the rotation of (nu) and (ru) is shown in Fig. 3 (C).
In FIG. 3 (D), which flows down into the valley of the feed spiral at 45 ° and is rotated by 45 °, it keeps flowing down, and as it rotates to FIG. 3 (E), the feed spiral pitch peaks (E), (f), and (g) are pressed against the front wall of the inner wall of the inflow port and the inner wall of the casing in the rotational direction, and the upper edge of the casing cut off by the inflow port is vertically moved from the horizontal axis direction. To form an arc of
When viewed from above, an arc is formed at the inlet side. The cut front edge of the casing, which forms an arc in the composite direction, is pushed by rotation as it rotates, and the feed spiral pitches (d), (e), (f), and (g), which change the pressing direction, are a kind of Performs the function of a cutting blade, shreds and cuts in combination with the above-mentioned pressing and crushing of the inner wall in front of the inlet and the curved inner wall in the rotating direction in the casing, and achieves the original purpose without blocking the inlet. Can be done. That is, the difficulty shown in FIG. 5 is solved by α <α ′ as shown in FIG. 4 (C).

Therefore, the feature of the present invention is that firstly, the first pitch of the feed spiral is larger than the inner diameter of the inlet in the feed spiral axial direction regardless of the shape of the inlet, which is circular, elliptical, or square. Second, the pitch is such that even if the feed helix rotates further from about 45 ° to about 90 °, the pitch hills do not appear in the inlet as viewed from above.

Further, in the present invention, FIGS. 3 (C), (D),
When the depths of the valleys in (E) are W, X, and Y, respectively, the relationship between these depths is 90 ° from FIG. 3 (C) so that the object can be reliably dropped and fed into the spiral. Until rotation W ≦
Advantageously, X ≦ Y.

In this case, the selection of whether to make the depth of the valleys after Y equal to Y or gradually shallower depends on the type of the object to be processed and the purpose of the processing.

And processing capacity when formed in the inlet and the feed spiral pitch as in the present invention, that the load increases,
With respect to the depth W of the valley in FIG. 3 (C).
By changing the depth of the W with reference to, and by changing the speed of rotation, the magnitude of the processing capacity and the increase or decrease of the load can be adjusted appropriately.

As a result, a large object can be processed with a small force, and the weight and size can be reduced.

The apparatus of the present invention can be used as a crushed shredded granulation apparatus by combining it with a granulation mechanism.

Advantageous Effects of the Invention The present invention, by having the above-described configuration, allows a variety of shapes to be processed supplied to an inflow port to be pushed smoothly regardless of the shape, and performs crushing and shredding. In addition to being able to do this, it is now possible to consolidate conventional multi-model and diverse devices into a single model, making it possible to unify models and make them the same standard. There is an advantage that the size can be reduced.
