BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a peeling machine for root vegetables and the like, and more particularly to a peeling machine capable of efficiently peeling a clean surface in a short time.

[0002]

2. Description of the Related Art Conventionally, as a skin peeling machine for peeling potatoes and other potatoes, a vertical cylindrical container is internally provided with a disk horizontally, and a plurality of stepped projections are circumferentially formed on the inner wall of the cylindrical container. In addition to the above, there is known a device in which the disc surface is configured to have a file-like rough surface, and potatoes are put into the file to rotate the disk so that the file-like rough surface is used to peel off the skin. ing. (JP-A-5-840
However, since the above-mentioned peeling machine is configured to gradually peel off the surface skin with a file-like rough surface, it took a considerably long time to peel off the entire surface skin. Moreover, since the surface of the potatoes is peeled off with a file-like rough surface, the surface of the potatoes becomes rough and the product value is unavoidable. Furthermore, the potatoes mentioned above frequently collide with the stepped protrusions on the inner wall during the long peeling work time, and the frequent collisions damage the softened surface layer, further reducing the product value. There was a problem.

Further, since the file surface of the file-like rough surface is clogged in a short time to reduce the peeling ability, the disk surface must be frequently washed, which is not always excellent in terms of productivity. I couldn't say that.

[0004]

SUMMARY OF THE INVENTION An object of the present invention is to be able to peel a clean surface in a short time and maintain the peeling ability without frequently cleaning the disk surface. To provide an excellent peeler.

DISCLOSURE OF THE INVENTION The present invention for solving the above-mentioned problems provides a peeling machine in which a disc is provided in a cylindrical container having a vertical axis, and a space above the disc is a peeling treatment section.
The inner wall surface of the cylindrical container corresponding to the peeling processing part is formed in a corrugated shape with curved surface irregularities in the circumferential direction, and a convex portion extending in the radial direction from the rotation center portion and radiation from the rotation center portion on the upper surface of the disc. The flat portions extending substantially horizontally in the direction are alternately arranged in the circumferential direction, and at least the front side in the rotational direction of the convex portion is an inclined surface, and the blade whose blade edge is directed to the flat portion in the rotational direction is parallel to the blade edge. It is characterized in that slits arranged and communicating with the lower surface side are provided.

As described above, the convex portions radially extending from the center of rotation and the flat portions extending substantially horizontally in the radial direction from the center of rotation are alternately arranged in the circumferential direction on the upper surface of the disc, so that the upper surface of the disc is covered. The lowermost layer that comes into contact with the skin is moved diagonally in the radial direction on the disk by the combined force of the accompanying force in the circumferential direction accompanying the disk rotation and the centrifugal force in the radial direction, and reaches the inner wall surface of the outermost cylindrical container. And then make contact,
The ball is ejected upward, and is dropped toward the center portion on the inner side in the radial direction, and the above operation is performed again, and this is repeated.

As described above, when the stripping material moves diagonally in the radial direction in the lowermost layer and is brought into contact with the blade of the flat portion, the skin is scraped. Since this movement is repeated as described above, the skin of the stripping material is removed. It will be stripped efficiently in a short time. Further, since the blade is used to scrape the skin, a clean surface can be finished without damaging the surface layer unlike the case of rubbing with a file-like rough surface. Further, since the blade and the slit are used to peel and drop the skin at the same time, the peeling ability can be maintained and the productivity can be improved without frequently cleaning the disc.

Further, when the blade edge is brought into contact with the stripping material being moved by centrifugal force obliquely, the stripping is performed so that the blade edge slices the epidermis, so that the surface of the stripping material after stripping is removed. It can be cleaned and the peeling ability can be significantly improved.

BEST MODE FOR CARRYING OUT THE INVENTION The peeling material applied to the peeling machine of the present invention includes root vegetables and fruits having a skin, for example, potato, taro, sweet potato, carrot, onion and the like,
Preferable examples include root vegetables having a nearly spherical shape and fruits such as chestnut with astringent skin.

FIG. 1 is a partial sectional view showing an embodiment of the peeling machine of the present invention.

In FIG. 1, a cylindrical container 1 is formed in a bottomed manner with the axial direction being the vertical direction, and a disc 2 is horizontally provided inside thereof at a position slightly above the bottom. In this way, the upper side of the cylindrical container 1 divided from the disc 2 is the peeling processing section 3, and the lower side is the peeling receiving section 4.
During the peeling process, a peeling material G is put into the peeling processing unit 3 as shown by a chain line.

The disk 2 is detachably fixed to the upper end of the rotary shaft 5 and rotates integrally with the rotary shaft 5. A knob 2a is provided at the center of the disc 2 and is used when the disc 2 is attached to and detached from the rotary shaft 5. The rotating shaft 5 penetrates upward from the lower surface of the cylindrical container 1 and is driven by a motor 6 fixed to the lower surface side.

The cylindrical container 1 is surrounded by a decorative plate 7, a lid 8 is detachably attached above the decorative plate 7, and an opening 8a is provided in the central portion of the lid 8 for introducing a peeling material. Also,
Inner wall 1a of the cylindrical container 1 at a portion corresponding to the peeling processing section 3
Are formed in a corrugated manner so that curved irregularities are repeated in the circumferential direction (see FIG. 4). Further, the inner wall surface 1a has an outlet 9 for taking out the stripped material, and a door 1 for opening and closing the outlet 9.
0 is provided.

A scraping plate 16 is provided on the lower surface of the disk 2.
One or more sheets are fixed so that they rotate together with the disk 2. The lower end of the scraping plate 16 extends substantially vertically to a position close to the bottom surface of the skin receiving portion 4, and
It extends in the radial direction from the center of rotation of the disk 2 to the vicinity of the inner wall surface of the skin receiving portion 4. The scraping plate 16 scrapes up the skin that has fallen onto the bottom surface of the skin receiving portion 4, and discharges it from the discharge port 11 to the outside of the apparatus.

As shown in detail in FIGS. 2 and 3, on the upper surface of the disk 2, a plurality of convex portions 12 and flat portions 13 radially extending from the center of rotation are alternately arranged in the disk circumferential direction (rotational direction). It is provided. In the illustrated example, the convex portion 12
Is four and the flat portion 13 is four.

The shape of the convex portion 12 is such that the height gradually increases in the radial direction from the center of rotation, and the two front and rear slopes 12f and 12r form a mountain shape in the circumferential direction of the disk. . The top portion connecting the two front and rear slopes 12f and 12r is formed into a curved surface so that damage caused by the collision of the stripping material G is reduced. In addition, this convex portion 1
The two front and rear slopes that form 2 are the front slope 1 in the rotation direction.
2f is formed to have a gentler gradient than the rear slope 12r.

The plurality is provided with protrusions 12, they are mixing different heights. When four convex portions 12 are provided as shown in the figure, two types of convex portions, that is, a high convex portion and a low convex portion are provided, and convex portions having the same height are arranged opposite to each other with the disc central portion sandwiched therebetween. Good. In this way, the convex portions 12 having different heights
By mixing the above, the movements of the peeling material can be randomly randomized, and the peeling action can be performed efficiently in a short time, compared with the case where all of them have the same height. Of course, the number of the convex portions 12 is not limited to four, and may be four or more or less than four depending on the type of the skinned material.

The flat portion 13 is formed in a horizontal plane from the center of rotation of the disk 2 to the outer end in the radial direction. A plurality of blades 14 are attached to the horizontal plane so as to be flush with the upper surface, and detachably attached so that the blade edges 14a face the rotation direction of the disk 2. In addition, the slit 1 is formed at the front end of each cutting edge 14a.
5 are bored in parallel and communicate with the skin receiving portion 4 on the lower surface side.

It is desirable that the width of the slit 15 can be adjusted according to the type of the material to be stripped. The blade 1 has a structure that enables adjustment of the slit width.
4 may be replaced with another blade having a different width, or the blade 14 may be fixed so as to be movable in the width direction. Slit 1
The width of 5 is preferably set in the range of 3 mm to 7 mm.

The cutting edge 14a of the blade 14 is the disk 2
It is preferable to incline like the inclination angles θ ₁ , θ ₂ , θ ₃ , and θ ₄ with respect to the radial direction (see FIG. 3). More preferably, a plurality of blade edges 14a may be arranged in parallel. When the blade tip 14a is arranged obliquely with respect to the radial direction of the disc 2, the blade tip 14a is cut obliquely to the peeling material G with respect to the traveling direction of the blade 14, so that the skin is easily scraped,
Moreover, since the impact when the stripping material collides with the blade edge 14a is mitigated, the life of the blade 14 can be extended. In addition, when a plurality of blade edges 14a are arranged in parallel,
Since the number of times the blade comes into contact with the material to be peeled is increased, it is possible to more efficiently peel the material in a short time.

Further, as described above, the blade 14 and the slit 15
In the configuration consisting of the combination with, since the skin does not remain around the cutting edge 14a, there is no concern of clogging such as a filed rough surface, and the peeling ability is improved even if the disc 2 is not frequently washed. Can be maintained for a long time. Further, it is possible to improve productivity.

The peeling action of the above-mentioned peeling machine will be described below.

First, with the disc 2 rotated, a peeling material G such as potatoes is put into the peeling processing section 3 through the upper opening 8a. The amount of the peeling material G to be added may be up to a state almost full below the upper edge of the peeling processing section 3. The outer peripheral speed of the disk 2 is 200
~ 400m / min range, rotation speed 200 ~
A range of 250 rpm is preferred.

When the disk 2 is rotated in the direction of the white arrow (see FIGS. 2 and 3), as shown by the chain line in FIG. 1, a large amount of the peeled material G gathers radially outward due to centrifugal force. Therefore, the surface height of the layered skinned material groups is low at the center of rotation and increases toward the outer side in the radial direction. In such a laminated state, the skinned material G of the lowermost layer is surrounded by the disk 2 by the frictional force of the disk surface and the pressing force of the slope 12f (the slope on the front side in the rotation direction) of the convex portion 12 and the disk 2. Move in the direction (rotation direction). However, the peeling material G
Moves (rotates) in a direction opposite to the moving direction of the disk 2 due to inertia, so that the circumferential speed of the skinned material moves as a whole with a speed difference slightly slower than the circumferential speed of the disk 2.

Further, in addition to the above-mentioned movement in the circumferential direction, the skin-peeling material G also receives a pressing force outward in the radial direction by a centrifugal force. Therefore, by summing the moving forces in both the circumferential direction and the radial direction, the skinned material G moves diagonally with respect to the disk radial direction, as indicated by the arrow in FIG. When the stripping material G moves diagonally in the radial direction in this manner, the skin is scraped by coming into contact with the cutting edge 14a of the blade 14 on the flat portion 13. The scraped skin falls through the slit 15 onto the skin receiving portion 4.

When the skin-peeling material G, which moves diagonally in the radial direction as described above, collides with the corrugated uneven surface of the outermost inner wall surface 1a, it is prevented from being entrained with the disk 2 and pushed upward. Further, the uppermost skin peeling material G is collided with the corrugated uneven surface of the inner wall surface 1a to drop toward the lower portion on the inner side in the radial direction. Further, since the slope 12f is formed on the front side of the convex portion 12 in the disc rotation direction, the peeling material G that moves diagonally in the radial direction on the disc as described above.
However, when riding on the slope 12f of the convex portion 12 from the flat portion 13, since it is repelled further upward, it is possible to more effectively perform the dropping action to the lower portion on the inner side in the radial direction.

The debarking material G that has fallen to the center of rotation of the debarking treatment section 3 repeats the above-mentioned action again and repeats many times.
Every time the flat portion 13 is crossed, the epidermis is scraped off by the blade 14, and the whole epidermis is peeled off. Further, when the above operation is repeated, since the inner wall surface 1a is formed in a corrugated shape having curved surface irregularities, the direction in which the skinned material G is repelled from the inner wall surface 1a inward in the radial direction is not constant but randomized. . Therefore, the skin position is changed every time the stripping material G passes through the blade 14 of the flat portion 13, and the same skin portion is moved to the cutting edge 14a.
The entire skin can be scraped off uniformly in a short time because it is not contacted with the skin. Further, since the inner wall surface 1a has a corrugated shape with curved surface irregularities, the surface layer is prevented from being damaged when the peeled material G collides.

Further, since the height of the convex portion 12 is gradually increased from the center of rotation in the radial direction (radial direction), the peeling material G gathers outward in the radial direction by centrifugal force. However, it is possible to move in the circumferential direction by receiving the pressing force by the convex portion 12 in the higher portion in the radially outer region. Further, the upward flipping action on the inner wall surface 1a can be more effectively performed.

Further, the cutting edge 1 of the blade 14 in the flat portion 13
When 4a is inclined obliquely with respect to the radial direction, when the stripping material G of the lowermost layer crosses the disk 2 obliquely,
Since the epidermis is cut diagonally, a larger area can be cut, and the epidermis can be stripped efficiently in a short time.

When all the stripping materials G put into the stripping processing section 3 as described above are stripped, the door 10 is opened while the disc 2 is rotating and the stripping material is taken out from the outlet 9. After that, the rotation of the disk 2 is stopped and the work is completed.

[0031]

As described above, according to the present invention, the material to be peeled can be efficiently peeled in a short time. In addition, since the skin is peeled off using a blade, it can be finished to a clean surface without damaging the surface layer like a conventional file-like rough surface. Since the peeling ability is maintained, the productivity can be improved.
