Description

  The present invention relates to a legume peeling apparatus and method for peeling raw legumes.

  Japanese Patent Laid-Open No. 11-225726 (hereinafter referred to as Patent Document 1) states that “the impeller (6) rotates, and the blades (7) that are twisted and bent so that the soybeans are scattered up and down and stirred very well, and the projecting surface (8). Since the projections (9) collide with the soybeans and peel off because they rotate in an arc, the agitation is so good that each soybean peels uniformly and has 90% or more round particles. There is a statement that peeled soybean can be produced. Separation of soybean seeds and skin is performed in a separate process.

JP 2001-103946 A (hereinafter referred to as Patent Document 2) states that “as the skinning material to be applied to the skinning machine of the present invention, root vegetables and fruits having skins, for example, potato, taro, Examples thereof include root vegetables such as sweet potatoes, carrots, onions and the like, preferably fruits such as chestnuts with astringent skin.
In a peeling machine in which a disk is provided in a cylindrical container on the vertical axis and the space above the disk is a skinning processing part, the inner wall surface of the cylindrical container corresponding to the skinning processing part is curved in the circumferential direction. Are formed on the upper surface of the disk, and convex portions extending radially from the rotation center portion and flat portions extending substantially horizontally from the rotation center portion in the radial direction are alternately arranged in the circumferential direction. A blade having at least a front side in a rotational direction of the portion as a slope, and a blade having a blade edge directed in the rotation direction on the flat portion and a slit that is arranged in parallel with the blade edge and communicates with the lower surface side is provided. . Is described.

“The outer peripheral speed of the disk 2 is preferably in the range of 200 to 400 m / min, and the rotational speed is preferably in the range of 200 to 250 rpm (paragraph number 0023)”.
“In addition to the movement in the circumferential direction as described above, the peeled material G is also subjected to a pressing force outward in the radial direction by centrifugal force. 2, the peel-off material G moves in an oblique direction with respect to the disk radial direction, as shown by the arrow in FIG. There is a description that “the skin is shaved by contact with the cutting edge 14a of the blade 14. The shaved skin falls to the skin receiving part 4 through the slit 15. (paragraph number 0023)”.

Further, JP 2002-65233 A (hereinafter referred to as Patent Document 3) states that “the rotating disk 1 is divided into the same number of inclined surface portions 12 by a plurality of steps 11 on the upper surface of the disk. The two steps 11 are divided into four slope portions 12 (FIG. 2), each step 11 having the same height, and its step surface is directed in the direction of rotation of the turntable 1. , Each step 11 is a gentle down slope from the next step 11 to the next step 11. As another embodiment, each step 11 has a different height, An embodiment in which the step surface is directed in the direction opposite to the rotation direction of the rotating disk 1 is also possible, and the round bar 10 of the rotating disk 1 is provided to stand upright and fixed to each inclined surface portion 12. In the embodiment, four slopes 4 in total, one each at 12. The height of the round bar 10 is the same as that of the cylinder of the cylindrical molting tank 2. In this embodiment, the bar 10 is a round bar. However, it may be a polygonal rod such as a quadrangle, the surface may be formed with a grindstone surface, a rod with an uneven surface vertically grooved, or a rod with an asymmetric shape, etc. (Paragraph number 0010, paragraph number 0011) ".

Then, “After turning on, when the electric motor 3 as the rotational driving means is operated, the rotating disk 1 fitted and fixed to the rotating shaft 30 starts to rotate in the cylindrical molting tank 2. This rotational speed is The garlic balls hit the rotating round bar 10 on the rotating disk 1 and in the cylindrical molting tank 2 when the rotating disk 1 begins to rotate. The garlic pieces and the garlic pieces are separated by the turbulent water flow caused by the step 11 and at the same time, the garlic balls and the garlic pieces are biased to the rotating peripheral side by the rotating centrifugal force, and the inner molting tank 2a of the cylindrical molting tank 2 While contacting the concavo-convex upper surface 20 which is the inner surface and the granular grindstone surface 21 (FIG. 3), the garlic balls which are hitting and falling apart, and the garlic pieces falling apart are rubbed and rubbed, Thin skin of N'niku piece will be peeled. Is described with (Paragraph No. 0019). "

JP-A-11-225726 JP 2001-103946 A JP 2002-65233 A

  However, in patent document 1, the structure is the same as that of a mixer, Moreover, since there is a blade edge | tip, there exists a problem that the body of beans is easy to be broken. Since more than 90% are peeled soybeans with round grains, 10% are crumbled. Since the body and the skin are not separated, there is a problem that they are mixed in the container and the beans and the skin are separated in a separate process. This separation process has the problem that it takes time and effort.

In Patent Document 2, there is a problem that not only the bean epidermis but also the body part of the beans is scraped off by contacting the cutting edge 14a of the blade 14 for peeling the root vegetables. Since the skin peeled off without being shaved is large, the skin and skin are not separated without being discharged from the slit. There is a problem that processing time is required.

In Patent Document 3, four round bars are erected and serve to break up lump garlic into small pieces, and there is no concept for peeling the skin. Spherical and ellipsoidal beans have a problem in that they are small in size, thick in skin and strong, so that they do not peel off while being rubbed against each other. Further, unlike the garlic pieces, not only the skin but also the body is scraped by contacting the concave and convex upper surface 20 which is the inner surface of the inner molting tank 2a of the cylindrical molting tank 2 and the granular grindstone surface 21. There is a drawback of being able to. Furthermore, since it is not in the state immersed in water, if agitation is strengthened, in the case of beans, there is a problem that the body is broken.
The cylindrical main body has a double structure with the cylindrical molting tank shown in FIG. 3, and there is a problem that scraps, skin and slime of beans remain, are easily rotted, and are difficult to clean.

Moreover, since it can be easily disassembled and assembled, it can be cleaned and stored hygienically.

An embodiment of the present invention will be described based on the apparatus of the present invention. FIG. 1 shows a sectional view of an apparatus according to an embodiment of the present invention. The legume peeling apparatus 1 includes an input unit 100, a cylindrical container unit 200, a peeling unit 300, a discharge unit 400, a stripping-out unit 500, a driving unit 600, and a gantry unit 700.
The input section is shown in FIG. The charging unit 100 includes a water supply port 101 attached to the lid 103, a shower nozzle 102, and a charging port 104 opened to the lid 103. The lid 103 is preferably made of a rust-resistant metal or alloy such as stainless steel or aluminum. The soaked beans are introduced from the inlet 104. A hose is attached to the water supply port 101 to supply tap water or circulating water. Water is discharged from the shower nozzle 102 at the water supply port in the form of a shower and supplied to the soaked beans. Keep the soaked beans soaked in water.
This input part 100 has a structure that can be easily removed from the upper part of the cylindrical container part 200.

A cylindrical container 200 is shown in FIG. The cylindrical container part 200 consists of a bottomless cylindrical pipe having a simple shape and a diameter of 350 to 900 mm and a length of 900 to 1800 mm. The axial direction is the vertical direction, the bottom part is placed on the gantry 700, the input part 100 is attached to the upper part so that it can be removed, and the peeled part 300 and the discharge part 400 are partitioned at the middle part. The inner wall is called a cylindrical container wall 201.
In the space between the skin peeling unit 300 and the input unit 100, the skin is peeled off. A stripping outlet 507 is opened in a part of the cylindrical container wall 201 in this space, and the stripping outlet 500 is attached thereto so that it can be removed.
A drainage port 404 is opened in the cylindrical container wall 201 below the drainage unit 400. From there, drain pipe 402 is taken out.

The peeled portion is shown in FIG. The peeler 300 is attached to the upper surface of the disk 306 so that the disk wave 308 and the peel bar 305305 can be removed. A shaft 617 of a variable speed motor 611 is connected to the center of the disk 306 via a connecting shaft 309 and fixed by a knob 307.
A layout diagram of the disk wave 308 is shown in FIG. A disk wave 308 is attached radially on the upper surface of the disk 306. Three, four, five, six, eight, nine or twelve disc waves 308 can be attached at equal angles. 4, 5, 6 are preferred. If the number is 8 or more, the upward flow hardly rises, and the same applies to the case of 3 sheets. When the disk rotates in the water, a rising water flow occurs due to the undulation of the disk wave 308. If there is a sharp corner, it will be easy to break the beans. Although the triangle c is less distorted, the rising water flow is weak and the upward movement is not good. The shape of the disk wave 308 is preferably an arc shape e and a kamaboko shape b, and the height is preferably 35 to 55 mm. If the height is low, the rise in water flow is weak and does not rise to the top. If it becomes too high, the body will collapse. The width of the disk wave 308 is preferably 55 to 70 mm. If the width is narrow, the collapse of the peeled body increases. If the width is too wide, the collapse of the peeled body disappears, but the rise of the water flow is weak and does not rise to the top.

6A to 6F show types of arrangement in which the peeling bar 305 is attached to the upper surface of the disk 306. FIG.
3 rows 4 rows (a) 3 rows 6 rows (b) 2 rows 4 rows (c) 2 rows 6 rows (d) 1 rows 4 rows (e) 1 rows 6 rows (f) ing. When the straight shape of the cylindrical container is 400 mm, the skin is hardly peeled when there are four rows (e) and six rows (f). When it is 3 rows and 6 rows (b), it peels well, but part of the beans collapses and begins to become waste.
It is more preferable to arrange so that the bean grains that have passed between the peeling bar 305 and the peeling bar 305 collide with the surface of the peeling bar 305 in the next row.

The types of the shape of the peel bar 305 are shown in FIGS. The shape of the peel bar 305 is preferably a triangle, a quadrangle, a pentagon, or a hexagon, and a rectangular parallelepiped plate is the best among the quadrangles. Polygons, cylinders, and elliptical cylinders that are larger than this can hardly be peeled off.
The width of the surface is preferably 25 to 40 mm.
There is a difference in how to peel the skin due to the inclination of the wide surface. When it is inclined at 40 to 50 degrees (130 to 140 degrees) with respect to the center line, about 50% collides with the entire surface, about 50% escapes, and the skin is peeled well by the repetition, which is preferable. In the case of 90 degrees, the beans don't collide with the surface, escape, and barely peel off. In the case of 0 degree, it collides with the whole surface too much, there is little escape, it turns around on the surface, and the skin is hardly peeled off.

The length of the peel bar 305 may be 1 to 1.3 times the bulk of the container when the soaked beans are introduced. If it is shorter than the upper surface of the soaked beans in a rotating state, the upper bean grains do not collide with the surface and rotate almost without peeling, so it is preferable that the beans protrude longer than the upper surface.
It is not necessary to apply anything to the surface of the peel bar 305. It is not preferable to give a file, a blade, or sharp-angled irregularities, rather than scraping the beans.

A cross-sectional view of the discharge portion is shown in FIG. The discharge part 400 includes a separation gap 310 that is a gap between the disk 306 and the inside of the cylindrical container part 200, a receiving plate 403 that is an elastic body and closely contacts the cylindrical container wall 201, a discharge pipe 402, and a discharge pipe 402. And an outlet 404. When the diameter of the beans is 4 mm or more, the width of the separation gap 310 is preferably 2 to 3 mm. If the gap is too narrow, the skin will not come out easily, and if it is too wide, the skin will come out, but it will also grow. Further, if the gap is too wide, the amount of drainage increases, and it is necessary to supply a large amount of water in order to keep the immersed beans in water.
The receiving plate 403 is provided with a gradient toward the discharge pipe 402. Instead of a waterproof structure in which an elastic body is attached to the circumferential portion to make contact with the cylindrical container wall 201, the receiving plate 403 is like a saucer so that skin and water are not scattered on the driving portion 600. There may be. Further, a shaft 615 passes through the center of the receiving plate 403, and water leakage prevention processing is performed by an O-ring or the like.
The discharge pipe 402 is a plastic double slide pipe and can be easily removed from the discharge port 404. Alternatively, a bellows type deformable pipe may be used.

FIG. 9 shows a schematic diagram of the stripped body extraction unit 500. A take-out port 507 is opened in the cylindrical container wall 201201, a door 506 is attached to the take-out port 507, and the handle 505 can be opened and closed. A take-out cover 504 is attached below the door 506. When the stripping is completed, the door 506 is opened, and the rotating disk is slowly rotated while supplying water, and the stripped material is taken out along with the water, poured out along the cover 504, and stored in the container.

A schematic diagram of the drive unit 600 is shown in FIG. The drive unit 600 includes a shaft 615 fitted to a shaft (pin) 617 of a variable speed motor 611 with an inverter, and a rotation control panel 619 including a switch 613.

FIG. 11 shows a schematic diagram of a gantry 700 on which the cylindrical container 201 and the drive unit 600 are placed. A gantry bottom plate 703 is attached on the gantry leg 701. A fastening plate 705 to which a variable speed motor 611 is fixed by a drive unit mounting screw hole 709 is installed at the center of the gantry bottom plate 703 through a screw hole 707. The cylindrical container 201 is placed on and fixed to the outer periphery of the gantry bottom plate 703.

[Method of peeling beans]
Each part that has been disassembled and cleaned is assembled into the peeling apparatus 1. In consideration of the kind and size of beans, the number of disc waves 308, the shape of the peel bar 305, the inclination of the peel bar 305, and the number of peel bars 305 are determined and adjusted.
A predetermined amount of dried raw beans is immersed in water having a water temperature of 10 to 30 ° C. for 3 to 12 hours. When immersed at 40 ° C or higher, the beans become soft and easily broken. If the soaking time is shorter than 3 hours, the skin is hard and difficult to peel off, and if soaked for 12 hours or more, fermentation and decay may occur. When soybeans are soaked, the beans are peeled off when the beans are pressed with fingers.

The raw soaked beans are put into the cylindrical container part 200 from the charging part 100.
The lid 103 of the insertion port 104 is made of aluminum that can be machined and does not rust. The size of the inlet 104 is set to 20 to 25 cm so that the soybean does not jump. Further, the lid 103 is formed in a mountain shape. By forming the lid 103 in a mountain shape, the impact on the lid 103 is small, so that the shape of the soybean does not collapse.
A hose is connected to the water supply port 101 of the peeling apparatus 1. Water is discharged from the shower nozzle 102 and supplied. When the soaked beans are watered, the switch 618 is turned on to gradually increase the rotation speed. When there is no water, slipping is bad and the soybeans collapse and become kneaded.
When the disk 306 of the exfoliated part 300 rotates in the water, a rising water flow occurs due to the undulation of the disk wave 308. The rotation speed is increased until the beans reach the upper end of the peeler 305. The rotation of the disk 306 is 2 to 5 rotations per second (120 to 300 rpm), preferably 180 to 240 rpm. The rotation direction is rotation in one direction. If the rotation speed is slow, the water flow will not rise, and if it is too early, the stripped material will be easily broken. The strip is rotating on the disk 306 with water. Because of the water, the shape of the bean does not collapse. Moreover, when reversed, it is easy to collapse. It takes time when the rotation speed is low.

The soaked beans go up and down. It hits the surface of the peel bar 305 and gradually goes away. The peeled thin skin is discharged together with water from a gap 310 between the disk 306 and the cylindrical container part 200.
That is, the bean grains collide with the peel bar 305 and peel off by the rising water flow generated by the rotating disk wave 308 in the cylindrical container. Separation due to the difference in resistance between the peeled skin and the skin due to water resistance, the peeled skin hits the cylindrical container wall 201 by centrifugal force, and is sucked into the separation gap 310 between the cylindrical container wall 201 and the disk by water pressure and received by the receiving plate 403. fall into. In this way, the peeled skin and the skin are continuously separated. The skin is drained from the drainage pipe along with the water.

After about 8 minutes, switch 613 is turned off once. Remove the beans from the container by hand and visually check the peeled state. If stripped is about 80%, switch it on again and operate. Rotate for 2-3 minutes. Turn off the motor, pick up the beans with your hands, and visually check. Confirm that it is 100% peeled off. Alternatively, a viewing window may be opened in a part of the cylindrical container wall 201 to confirm that it has been peeled off.
The handle 515 of the stripping-out portion 500 is twisted, the door 506 is opened, the disk 306 is rotated slowly while supplying water, the stripping body is taken out along the cover 504 with water, drained, and stored in a container.
Subsequently, the raw soaked beans are put into the cylindrical container part 200 from the feeding part 100 and the peeling operation is repeated.
When the work is finished and the state is left as it is, scraps of the body, skin, and slime stick to the disk 306 and the outer wall container wall 201 and rot, so the bean peeling apparatus 1 is immediately disassembled and cleaned.

[Soy peel]
5 (2), the number of disc waves 308 is four, the shape of the peeling bar 305 is plate-shaped, the inclination of the peeling bar 305 is 45 degrees, and the number of peeling bars 305 is 12 in 6 rows.
Weigh 3 kg of dried soybeans with a measuring instrument and place in a large barrel. Wash it well by hand. Wash once, twice, up to 3 times. It was immersed in 3 liters of soybean in an amount of 6 liters of water at a temperature of 20 to 25 ° C. for 7 to 8 hours. Since dry soybeans have a hard skin, water gradually soaks into the soybeans over time. Skin and body are easily detached. The state in which the soaking of the soybeans has been completed is when the skin is peeled off when the soybeans are touched with the hand and pressed with the fingers. This is called soaked soybeans.

Soaked soybeans were introduced from the inlet 104. The hose is connected to the water supply port 101 of the peeling apparatus. The lid 103 of the insertion port 104 is made of aluminum which is easy to work and does not rust. The size of the inlet 104 was set to 20 to 25 cm so that the soybean would not jump. Further, the lid 103 is formed in a mountain shape. By forming the lid 103 in a mountain shape, the impact on the lid 103 is small, so that the shape of the soybean does not collapse. Twist the faucet and drain the shower. An amount of 40-50 liters was sprinkled in about 1 minute. The drive switch 613 is turned on. The exit of the shower is net-like. The shower is at the top. When the water is drained, it becomes a shower, so the water spreads and takes over the whole. The peeled skin and the skin are separated by the shower water, and only the skin falls in the separation gap 310. When there is no water, slipping is bad and soy breaks down and becomes kneaded. The body rotates on the disk 306 with water. Because there is water, the shape of the soybean does not collapse.

The disk 306 was rotated at 180 rpm and rotated in one direction. Soy does not come out of the container and turns well without resistance. Rotation peel time was 8-10 minutes.
The peel bar 305 was made of stainless steel so as not to rust, and a plate having a thickness of 3 mm was used to maintain the strength. The inclination of the peel bar 305 was 45 degrees. When it is made into a plate shape, it hits soybeans well and does not crush but peels off well. The width of the peel bar 305 is 30 mm, the number of peel bars 305 is 12 in 6 rows, so that soybeans escape and resist well. Therefore, peel off well. The position of the peel bar 305 is divided into six equal parts and has two lines in one row. One from the center, one at a position relative to the circle, and one at two thirds. The shape of the disk wave 308 is a kamaboko shape and is four.

As the disk 306 rotates and there is a peeler 305, soy begins to turn. The soybeans are showered, and water always enters between the soybeans and the soybeans. The soybean hits the peel bar 305 and peels off gradually. Since there is a disc wave 308, the lower soybeans go up and the upper soybeans go down. Soybeans repeat up and down by rotation. At that time, the skin is detached together with water, separated by centrifugal force, hits the cylindrical container wall 201, passes through 2 mm of the separation gap 310, and is discharged from the drain outlet 404.
Turn off switch 613 once after 8 minutes of operation. The soybeans were taken out of the container by hand and the peeled state was visually observed. Since the stripped off was about 80%, it was switched on again and it was activated. Rotated for 2-3 minutes. The motor was switched off, the soybeans were picked up by hand and visually observed. It was confirmed that 100% was peeled off.

The peeled soybean opens the outlet door 506 while slowly turning the variable speed motor 611 without turning off the switch 613. If it does so, it will flow out along the taking-out cover 504 of the 95-98% peeled-out part 500 automatically, without taking out by a centrifugal force. Receive it in a 45-50cm basket placed outside. Remove the remaining soybeans in the container by hand.
On the other hand, a 30-35 cm basket is prepared under the skin drain outlet 404 to receive the skin.
After removing the striped soybeans, stop the tap water shower. After that, wash the container thoroughly with tap water and wipe off the moisture with a dry towel.
The results are shown in Table 1. It was recovered with almost no stripping.
[Comparative Example 1]

The same procedure as in Example 1 was performed except that the number of the peel bars 305 was one for each row. As a result, there was a lot of escape and the soybeans were not beaten, so the skin was hardly peeled off.
[Comparative Example 2]

Example 1 was repeated except that the number of disc waves 308 was four. As a result, the water flow was strong and there were many waves, so the soybeans were beaten well and scraped off.

[Soy peel]
The procedure was the same as Example 1 except that the number of disc waves 308 was 6 and the rotation speed was 240 pm. As a result, it was possible to recover with almost no peeling.
[Comparative Example 3]

The procedure was the same as Example 2 except that the rotation speed was 400 rpm. As a result, the water flow was strong, the soybeans were beaten well, and they collapsed to produce debris. Yield is bad.
[Comparative Example 4]

The peel bar 305 was the same as Example 2 except that the shape of the peel bar 305 was a round bar or an octagonal bar. As a result, almost no skin was peeled off.

[Soy peel]
The width of the peel bar 305 is 25 mm, the inclination of the peel bar 305 is 35 degrees, the number of peel bars 305 is four rows and eight, the number of disk waves 308 is four, and the rotation speed is 120 rpm. The procedure was the same as in Example 1 except that.
Although it took some time, it was recovered with almost no peeling.
However, when the rotational speed was set to 80 rpm in the same manner, it took a very long time to peel off.

The table shows the results of experiments performed by changing the number of disk waves 308, the shape of the peeling bar 305, the inclination of the peeling bar 305, the number of the peeling bars 305, and the like, and changing the number of rotations. In the figure, ◎ means good, ○ means slightly good, Δ means slightly bad, and × means bad.

[Peanut skinning]
Weigh 30 kg of peanuts with a measuring instrument and place in a large barrel. Wash it well by hand. Wash once, twice, up to 3 times. The amount of water was 60 liters with respect to 30 kg of peanuts, the temperature was 20 to 25 ° C., and the immersion time was 10 to 12 hours. Peanuts are thicker and harder than soybeans, so they have a longer dipping time of 20-30% than soybeans. As the state of peanuts, when the hand is touched and the finger is pressed against the peanuts, the peanuts are immersed if the skin is peeled off.

About 5 kg of the peanut soaked was introduced from the inlet 104. The hose is connected to the water supply port 101 of the peeling apparatus. The size of the inlet 104 was set to 20 to 25 cm so that peanuts did not jump. Further, the lid 103 is formed in a mountain shape. By forming the lid 103 in a mountain shape, the impact on the lid 103 is small, so that the shape of the peanut does not collapse.
Twist the tap and let out shower water. An amount of 40-50 liters was discharged in about 1 minute. The drive switch 613 was turned on. The exit of the shower is net-like. The shower is at the top. When the water is drained, it becomes a shower, so the water spreads and takes over the whole. The flesh and skin of peanuts floated in the shower water, and only the skin passed through the separation gap 301. When there is no water, slipping is bad, peanuts collapse and become kneaded. The stripped body rotated on the disk 306 with water. The shape did not collapse due to water.

The disk 306 was rotated 3-4 times per second. 180-240 rpm.
One-way rotation. The skinning time was 8 to 10 minutes. The peel bar 305 was made of stainless steel so as not to rust, and a plate having a thickness of 3 mm was used to maintain the strength. The inclination of the plate is 40 to 45 degrees. When made into a plate shape, peanuts hit well, they did not break and peeled well. The width of the peel bar 305 was 60 mm, and the number of peel bars 305 was 12 in 4 rows, and the condition of peanut escape and resistance was good. Therefore, it peeled off well. The position of the peel bar 305 is divided into four equal parts, and is divided into three lines. From the center, one was set up at a position of a quarter, a position of a quarter, and a position of a quarter.

There are four disk waves 308. It is located in a quarter of a circle and has a circular arc shape. The height is 40 mm and the width is 60 mm. As the disk 306 rotates and there is a peeler 305, peanuts begin to turn. A shower is put on the peanuts, and water enters between the peanuts and the peanuts, and they turn around without breaking. The peanut hits the peel bar 305 and peels off gradually. Due to the disc wave 308, the bottom peanut goes up and the top peanut goes down. Peanuts repeat up and down by rotation. At that time, the skin was separated from the peeled body together with water, separated by centrifugal force, hit the cylindrical container wall 201, passed through 2.5 mm of the separation gap 310, and discharged from the drain outlet 404.

After about 7 minutes, the switch 613 was turned off once. The peanut was taken out of the container by hand, and the peeled state was visually observed. Since it was 80% peeled off, it was turned on again and operated. Rotated for 2-3 minutes. The motor was turned off, the peanuts were taken by hand and visually observed. It was confirmed that it was 100% peeled off.

To remove the stripped peanut, the lid 506 of the outlet is opened while turning the variable speed motor 611 without turning off the switch 613. If it does so, even if it does not take out by hand with centrifugal force, it will come out from the 95-98% peeled-out part 500 automatically. Received in a 45-50cm net cage placed outside. Remove the stripped peanuts remaining in the container by hand. After removing stripped peanuts, stop the tap water shower.

On the other hand, a 30-35 cm basket is prepared under the skin drain outlet 404 to receive the skin. Then wash the container thoroughly with tap water and wipe with a dry towel.
The results are shown in Table 2. The thin skin was removed, and it was recovered with almost no peeling.

[Comparative Example 5]

The number of revolutions is 400 rpm, the shape of the peel bar 305 is a plate, the inclination of the peel bar 305 is 25 to 35 degrees, the number of peel bars 305 is twelve, and the number of disc waves 308 is four rows. The procedure was the same as in Example 5 except that. The results are shown in Table 1. The number of revolutions is fast, many collapses occur, and the yield is poor.

[Peanut skinning]
The rotation speed is 150 rpm, the shape of the peel bar 305 is a plate, the inclination of the peel bar 305 is 50 degrees, the number of peel bars 305 is 2 rows, 12 rows, and the number of disc waves 308 is 6 rows. The procedure was the same as in Example 5 except that.
As a result, the stripped material was not broken and could be collected in a predetermined time of 10 minutes.
[Comparative Example 5]

The same procedure as in Example 5 was performed except that the rotation speed was 80 rpm.
When the peel bar 305 is tilted at 25 degrees, the tilt is small, so that the resistance is strong and the rotation becomes heavy, which makes the motor impossible. When the number of peel bars 305 is set to 12 in 2 rows, the soybeans collapse and rise well up and down.
