Description

Detailed Description of the Invention (Field of Industrial Application) The present invention relates to a method for peeling the inner fruit of citrus fruits and a cutting method used during peeling, and is used when peeling the inner fruit of citrus fruits as a fruit or vegetable. be done.

(Prior art and its problems) When peeling the endocarp of citrus fruits, the endocarp is separated one by one after the exocarp is removed, and then the endocarp (sac) is formed by acid and alkali treatment. The only way to put it on the market was to remove the pectin by dissolving it, and then putting it in cans or bottles with the syrup.

However, it has been found that removing the endocarp through chemical treatment impairs the original taste of the fruit and has a negative effect on the human body, and it has been pointed out that the endocarp should be physically removed. ing.

By the way, at present, there is no other solution to physically removing the endocarp other than using human tactics.

Manually removing the endocarp involves cutting the central part of the medial malleolus with a knife and then peeling off the skin on the side of the medial malleolus, but this method is extremely inefficient. In addition to being sanitary, there is also the disadvantage that the meat falls apart and loses its commercial value.

(Technical Problem) An object of the present invention is to enable the separated inner fruit of citrus fruit to be removed hygienically while retaining its shape.

-First Invention- (Technical Means) The first invention for solving this technical problem relates to a method for shedding the medial malleolus. After cutting the lateral edge of the pericarp in an arc shape, the central lateral edge of the medial malleolus is cut.

(Action of technical means) When the outer edge of the separated medial malleolus is cut into an arc shape,
The endocarp is removed along with some of the flesh.

On the lateral edge of the medial malleolus, the vesicular body is densely packed in a granular manner, and the vesicle body retains well, so there is no fear that the medial malleolus will collapse.

Moreover, since the fibers that bind the endocarp and the flesh are oriented in opposite directions, the skin will not peel off from the cut edge and cause problems in subsequent processes.

Next, when the center side of the medial malleolus is cut in a straight line along the edge, the skin on both sides of the medial malleolus becomes independent and can be easily peeled off from the center side.
The skin can be removed while preserving the shape of the inner malleolus.

(Effects of the present invention) Since the shape-retaining ability can be maintained until the final step of shedding the medial malleolus, there is an advantage that the medial malleolus can be smoothly shedding. Since the outer edge of the medial malleolus is excised in an arc shape, it can be molted even if it is divided into appropriate sizes with the outer skin still attached. Moreover, it is hygienic, the outflow of fruit juice can be minimized, and the fruit pulp has the advantage of being good in taste.

-Second to Sixth Inventions- (Technical Means) The second to sixth inventions all relate to a method of cutting the outer edge of the medial malleolus, and the technical means thereof is to provide a cutting edge on the distal edge. The provided cylindrical body is rotated, and the medial malleolus is advanced into the inner side of the cylindrical body, and the outer edge of the medial malleolus is cut into an arc shape (Claim 2).

Methods for cutting the outer edge of the medial malleolus into an arc shape include: a method in which an endless running body equipped with a center-side holding means and a side-side supporting means for the medial malleolus is passed through the cylindrical body (claim 3); There is a method (Claim 4) in which a support table, in which the medial malleolus is placed vertically and the medial malleolus is placed horizontally, is introduced into the cylindrical body.

At this time, the tip of the former holding means can be formed into a sawtooth shape (Claim 5).

The center side of the medial malleolus can be cut by running the endless running body in a concave shape and tilting the holding means toward the supporting means (Claim 6).

(Operations and effects of technical means) When the medial malleolus is supported and entered inside the rotating cylindrical cutting blade, the portion of the outer edge of the medial malleolus protruding from the cutting blade will be cut in an arc shape. Become.

At this time, since the cutting blade is rotating, it has the effect of smoothly cutting the medial malleolus and preventing the fruit juice from inadvertently flowing out or scattering (Claim 2).

When the medial malleolus is placed along the side support means of the endless running body and its center side is held by the holding means, the medial malleolus is supported by the endless running body in an upright or inclined state, and in that state it is continuously moved inside the cylindrical body. Since it is passed through, there is an effect that the outer edge of the medial malleolus is cut smoothly and continuously (Claim 3).

If the cylindrical body is arranged vertically and the support base with the medial malleolus placed horizontally is relatively advanced into the cylindrical body, the medial malleolus will not be placed in an upright or inclined state.
The outer edge of the medial malleolus can be smoothly cut by the rotating cutting blade (Claim 4).

Since the outer edge of the medial malleolus is cut, there is no need to peel off the outer skin and process each bag individually, and the medial malleolus can be cut into appropriate sizes with the skin on and processed.
The integument will be excised along with the lateral edge of the medial malleolus.

The holding means has the function of holding the center side of the medial malleolus, but since its tip is formed into a saw blade shape, when the holding means is moved forward, the center side of the medial malleolus is cut off. That will happen.

Depending on the forward width of the saw blade, the holding means may cut only the skin on the near side of the center of the medial malleolus, or may cut both the skin on the near side and the skin on the supporting means side. In any case, since this is performed after cutting the outer edge of the medial malleolus, there is an advantage that damage to the flesh and outflow of fruit juice can be minimized (claim 5).

When the endless running body is run in a concave shape, the holding means supported by the endless running body and the side support means are forced to approach each other, the holding means is tilted toward the supporting means, and the supported center of the medial malleolus is held. The saw blade of the device will cut through the center of the medial malleolus.

Therefore, there is an advantage that all cutting of the medial malleolus is automatically performed during transportation, and that the medial malleolus itself is kept sanitary without manual contact (Claim 6).

(Example) Next, a specific example of the above technical means will be described with reference to the drawings.

FIG. 1 is a side view of essential parts of the medial malleolus cutting device.

A chain 1 as an endless running body that conveys the medial malleolus m has left and right sprockets 2, which rotate at a constant speed.
3 and travels in the direction of the arrow.

On the chain 1, a pair of inclined plates 4, 4 for supporting the medial malleolus m in an upright state and support plates 6, 6 for holding the center side of the medial malleolus m in front are fixed. .

A saw blade 7 is provided on the support plate 6 in a protruding manner opposite to the locking plate 4 (see Fig. 4), and the cutting edge of the saw blade 7 can enter into the inclined line 4 when the support plate 6 moves forward. Small hole 5,
5 (see Figure 3).

Point p where chain 1 reverses at sprocket 3
In this case, the distance between the inclined plate 4 and the support plate 6 becomes larger due to the difference in curvature, so that the medial malleolus m is exposed between them.

When the chain 1 moves forward and moves horizontally, the relationship between the inclined plate 4 and the support plate 6 is narrowed, and the tip of the saw blade 7 of the support plate penetrates into the center of the opposite fruit m and supports it. to move forward.

A cylindrical body 11 is arranged on the outside of the chain 1, and a cylindrical cutting blade 12 is fixed to the rear end side (on the right side in FIG. 1), and the medial malleolus m supported by the chain 1 is , is forced to pass through the cutting edge 12.

Although the cutting blade 12 is shown as having a flat blade surface in the drawing, it can also be formed in a wavy or serrated shape. Incidentally, the cutting blade 12 may be divided into two parts to facilitate maintenance and inspection, and the cutting blade 12 may form a cylinder in the attached state.

The cylindrical body 11 is rotatably supported via bearings 33, 33 within a frame 32 suspended from a frame 31 fixed on a base 30 of the device, and is also housed within the frame 32. It is designed to rotate under the drive of a motor 34 (see Fig. 2).

Incidentally, this frame body 32 is fixed to the top of the frame 31 with supports 35, 35 so that its height can be adjusted.

A guide rail 13 for guiding the chain 1 is arranged inside the cutting blade 12. rail 1
The front and rear ends of the chain 1 are fixed to the frame 31 by support members 14, 14, and the chain 1 is connected to the cutting blade 12.
This allows the medial malleolus m to run without causing any core deviation within the medial malleolus (see Figures 1 to 3).

The height of the chain 1 can be adjusted by moving bolts 10, 10 attached to the rail 13 back and forth. Therefore, by appropriately adjusting the height of the frame body 32 and the height of the rail 13, the cutting location of the outer edge of the medial malleolus m is determined.

The medial malleolus m, which is made to pass through the cutting blade 12, has its outer edge protruding from the cutting blade 12 cut into an arc when it enters (see dotted line a in Figure 5).

In front of the cutting blade 12, rotary blades 15 are arranged facing each other on the left and right sides of the chain 1 (only the front side is visible in FIG. 1). This rotary blade 15 rotates in an inclined state with a large distance between the upper sides facing each other, and cuts both sides of the lower end of the medial malleolus m obliquely (see dashed lines b and b in FIG. 5).

The chain 1 engages with the sprocket 16 after passing through the rotary blade 15. This sprocket 16
is linked with the sprocket 2 mentioned above,
Moreover, since there is no support member below the two sprockets 2 and 16, the chain 1 will be slightly bent downward.

Above the bending portion 17, a rotating roller 21 is arranged, which has a configuration in which a pair of left and right discs 22 are connected by a plurality of connecting rods 23, 23 arranged at the peripheral edge.

The connecting rods 23 are on the same circumference,
They are arranged at the same spacing as the spacing between the supports 6, 6, and when the rollers 21 rotate in the direction of the arrow at the same speed as the chain 1, each connecting rod 23 presses the front part of the support plate downward.

Therefore, when the roller 21 is rotated in the direction of the arrow at the same speed as the chain 1, the connecting rod 23 causes the chain 1 to be deeply bent, and the support body 6 is moved toward the inclined plate 4.
It is tilted to the side, and the saw blade 7 is advanced toward the inclined plate 4 to push through the central part of the medial malleolus m (see the two-dot chain line c in FIG. 5).

After that, chain 1 moves forward and sprocket 2
The inclined plate 4 and the support plate 6 separate at a point q where they are reversed on the outside, but the medial malleolus m whose periphery has been cut falls here in a state where the endocarp can be easily peeled off.

In the above embodiment, the outer edge of the medial malleolus m is cut into an arc shape and then the center part is cut, but only the endocarp in front of the center of the medial malleolus, that is, on the side of the support 6, is cut by the support. It is also possible to cut the medial malleolus and then cut the lateral edge of the medial malleolus.

Furthermore, the rotary blade 15 is used to cut diagonally the left and right ends on the center side of the medial malleolus m, but this is done in order to make it continuous with the cut on the center side of the endocarp to facilitate peeling. In addition to cutting in an inclined state, it can also be cut horizontally, and when the cutting line on the outer edge of the medial malleolus m and the cutting line on the center side are sufficiently close to each other, a rotary blade is used. 15 is not necessary.
