Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a method for peeling a substantially spherical fruit, such as a grape grain, from which the outer skin can be released, and a falsification calendar for cutting the outer skin of the fruit used in the method. be.

(Prior art and its problems) In the past, grapes were peeled by crushing them one by one by hand using human labor techniques.

Peeling grapes by hand is inefficient, expensive, and unhygienic.Furthermore, the grapes are compressed and thickened, resulting in loss of fruit juice and deterioration of flavor. When dried or added to juice, the specific gravity becomes lighter and floats due to the reduction in fruit juice, making the product unsatisfactory. In addition, devices for peeling tangerines have already been introduced in Hakama Kosho No. 40-15 No. 4 and Samurai Kosho No. 40-121237, and a presser belt with feeding action is rearranged on two rollers. A device is disclosed in which a mandarin orange that has undergone the steps of boiling and cutting the skin is guided onto rollers, and the skin of the mandarin orange is peeled by biting into the skin.

These known techniques do not disclose any methods for cutting the outer skin.

In the case of mandarin oranges, it is common to place the mandarin oranges between a pressure roller and a roller with claws or blades, or to place a rotary blade on a belt conveyor to cut the outer skin during transportation. However, since the width between the rollers or between the belt and the rollers is constant, it is necessary to sort the oranges in advance so as not to damage the fruit, resulting in extremely poor work efficiency.

In the former Koyoin technique, the biting roller group must be rotated and revolved, so the entire device is large-scale, and the disadvantage is that peeling cannot be performed unless the supply of mandarin oranges is stopped during the revolution of the roller group. There is.

In addition, in the latter known technology, since one of the rollers has a claw blade, the flesh of the mandarin oranges is damaged when the outer skin is peeled, and the fruit juice is lost, which reduces the commercial value of the mandarin oranges. become.

In order to solve the above problems, this application includes the following two inventions.

[Regarding the first invention] (Technical problem) The first invention relates to a method for peeling the outer skin of salvage-shaped fruits such as grapes and mandarin oranges, and the problem is to peel the skin of the fruit. be.

(Technical means and their effects) The first invention to solve this technical problem is to cut the outer skin from below with a rotary cutting body arranged below the transition path while transferring the fruit. This method ensures that all the fruits with different grain paths undergo gongyang, and the cut fruits are guided along with water between two automatic rollers arranged in parallel, and while pressing, the rollers use water as a lubricant. The technical means is that by moving the roller forward in the middle, the outer skin of the fruit is bitten into the rollers while adjusting to the size of the grain, and the outer skin is smoothly removed.

(Effects of the Invention) Therefore, according to the method of the present invention, the skin can be automatically and continuously peeled without any manual effort without having to separate the fruit, making the peeling work extremely efficient. Moreover, since the flesh of the fruit is not crushed, it is possible to prevent the juice from decreasing, and the taste is not impaired. [Regarding the second invention] (Technical problem) The second invention relates to a device for cutting the outer skin of fruit, which is used to carry out the first invention. The goal was to cut only the outer skin of the fruit without cutting.

(Technical means and their effects) The second invention to solve this technical problem is to form a slit in the transfer device for transferring fruit or in a direction perpendicular to the transfer direction so that the fruit passes through the slit. Then, place the rotary cutter's body below the slit so that the tip of the injured part faces into the slit.
The technical means is to cut the outer skin from the underside of the fruit as it passes. (Effect of the invention) Therefore, according to the above-mentioned technical means, since the rind is always cut from the lower side of the transition path where the fruit is in contact, the rind can be cut regardless of the size of the fruit. There is no need to sort the fruit.

Furthermore, by positioning the height of the rotary cutter according to the thickness of the outer skin, the flesh of the fruit will not be incised unnecessarily.

(Embodiment) In the above technical means, the cut body is placed on a rotating roller,
It may be formed by arranging a large number of sharp objects such as needles, claws, blades, etc., or may be formed by rotating blades.

The easiest way to transfer fruit is to use a gutter or an inclined plate to roll the fruit, but if a gutter is used, it is desirable to provide slits in the direction of transfer. [Embodiments of the Two Inventions] Next, an example of an apparatus for carrying out the first invention will be described with reference to the drawings together with an embodiment of the second invention in the case of peeling grapes.

FIG. 1 schematically shows a device for cutting the outer skin of grapes 1, in which the grapes are advanced by a compare belt 2, guided to a slanted plate 5, and transferred over the grapes.

A slit 6 is formed in the slanting plate 5 at right angles to the transfer direction, and a rotating roller 3 with a large number of needle-shaped bodies 4 is disposed below the slit 6, and the grapes passing through the slit 6 are 1
The grapes 1 are transferred onto the compare belt 7 in front of them. The grapes 1 transferred from the belt 7 to the chute 18 advance upward between the two rollers 10, 10.

The rollers 10, 10 have surfaces 11 made of rubber, are arranged in parallel with a slight interval, and are rotated in the biting direction by a driving means (not shown).
(See Figure 3). An endless belt 12 is run above the rollers 10, 10. This endless belt 12 is
A slightly thick rubber sponge body 14 is provided on the outer surface of the V-belt 13.
The roller 1 is guided by pulleys 15 and 16 located on both ends between the rollers 10 and 10.
1 and 11 (see Figures 2 and 3). The pulley designated by reference numeral 17 guides the inorganic belt 12, and is configured so that a bearing (not shown) can move upward, so that the tension of the endless belt 12 can be adjusted.

The inorganic belt may be of any type as long as it has the function of applying a slight pressing force to the grapes, etc. and promoting the advancement of the grapes, etc. between the rollers, and its surface may be made of a sponge material such as rubber, or may be made of felt, etc. The base may be made of fibers of
It may be constructed such that a large number of rolls are arranged inside a flexible endless belt and each roll is pressed by a spring.
Instead of these inorganic belts, flexible blades made of rubber or the like may be installed on the rollers, and the elasticity of the blades may be used to press and move the grapes forward.
