要となる。この皮剥きは従来人手により１個ずつ剥いて
いたが、きわめて非能率的であって、多量の需要に対し
対応しきれなかった。(Prior Art) Grapes are used for canned cakes and fruit juice drinks, but in both cases it is necessary to peel the grapes before processing. Conventionally, this peeling was done manually, one by one, but this was extremely inefficient and could not meet the large demand.
一方、機械的に剥皮する装置として、従来特開昭５８−
１３３７５号公報に示されるものが提供されている。On the other hand, as a mechanical peeling device, there has been a conventional
The one shown in Japanese Patent No. 13375 is provided.

挟み込みが容易になるようにしている。This device supplies grapes with skins between a pair of rolls installed in parallel, and peels the skins by rotating these rolls in opposite directions. The grapes with skins are sent downward between these rolls and the cheno, and the cheno presses the grapes with skins between the pair of rolls 1, so that the skins can be easily pinched by the rolls.

う問題があった。(Problem to be Solved by the Invention) However, in the above-mentioned peeling device, not only the skin of the grape but also the fruit (grain) tends to get caught between the pair of rolls, probably because the pressing by the cheno is unreasonable. As a result, there was a problem in that about 5 to 10% of the supplied grapes were crushed.
本発明はこれに鑑み、ぶどうを潰すことなくスムーズに
皮を剥くことができる剥皮装置を提供することを目的と
してなされたものである。In view of this, the present invention has been made for the purpose of providing a peeling device that can smoothly peel grapes without crushing them.

。(Means for Solving the Problems) In order to solve the problems of the above-mentioned prior art, the present invention provides the following:
In a grape peeling device that uses the rotation of a pair of rolls in opposite directions to peel the grapes, a feed roll is disposed directly above and parallel to the pair of rolls at a required interval, and this The feed roll has a spiral protrusion on its circumferential surface, and this protrusion allows the grapes to be fed between a pair of rolls while being pressed between the rolls, and the skins of the grapes are sandwiched between the rolls and peeled. It is characterized by the fact that

れて剥皮される。(Function) When grapes with skins are fed between a feed roll and a pair of rolls located below it, when the grapes are fed on the rolls by the spiral protrusions as the feed roll rotates, the grapes are fed by the protrusions. The grapes are pressed between the rolls, and a portion of the skin is sandwiched between the rolls and pulled down between the opposing rolls to be peeled.
（実施例） 以下、本発明を図面に示す実施例を参照して説明する。(Example) The present invention will be described below with reference to embodiments shown in the drawings.

留部７とに区画されている。In the required area of the supply side A of the roll 1.1 and the feed roll 2, a hopper 4 is provided to facilitate the supply of grapes D. In the illustrated embodiment, the hopper 4 has a V-shaped cross section, and a partition plate 5 is provided at the upper center of the hopper 4, and as shown in the third figure, a grape input section 6 and a temporary storage section 7 are separated. It is divided into.
このホッパ４の下端は、対のロール１．１の外側周面に

る。At the discharge end of the hopper 4, as clearly shown in FIG. After being peeled, the grapes are sent from above the rolls 1, 1 to the temporary storage section 7 of the hopper 4, and when they are sent to the discharge side B by the protrusion 3 of the feed roll 2, they can come out of the hopper 4. The window hole 9 is opened as shown in FIG. Furthermore, hopper 4
A window hole (not shown) for passing through the feed roll 2 and the pair of rolls 1.1 is opened on the opposite side of the window hole 9.

A scraping member 11 for scraping off the upper grapes is fixedly provided so as to protrude from the peripheral surface of the feed roll 2 and extend in the axial direction.
つぎに上記実施例の作用を説明する。Next, the operation of the above embodiment will be explained.

れる（第１図参照）。If grapes with skins are put into the input part 6 side of the hopper 4 and the pair of rolls 1.1 and the feed roll 2 are rotated in the direction of the arrow in FIG.
When the ridge 3 hits the upper end of the grape D and presses the grape D between the rolls 1.1, The skins of grape D are sandwiched between rolls 1.1, and the rotation of rolls 1.1 pulls the skins downward, and since the grapes themselves have a lot of water, the skins easily separate from the fruit, leaving only skins E. It passes between the rolls 1 and 1 and is discharged downward. This is because the skin of the peeled fruit is smooth and has a lot of moisture, and the ridges 3
Since no unreasonable pushing force is generated, the paper is not pinched between the rolls 1.1 and crushed, and is pushed by the protrusion 3 of the feed roll 2 and sent to the discharge side B. Roll 1.1
When the peeled grape D' on top comes out from the end of the feed roll 2, it is removed by the scraping member 11 of the feed roll 2.
is scraped off to the side and collected into the lower container 10 (see FIG. 1).

器１０内に回収される。The peeled grapes D' are pushed by the force of the grapes with skins being fed from the supply section 6 of the hopper 4 while being fed between the rolls 1. Some of it is pushed out to the storage section 7 side, but this is also temporarily pushed by the protrusion 3 on the side wall of the roll 1 and hopper 4 on the storage section 7 side, sent to the discharge side B, and passed through the window hole 9. When it comes out of the container, it is collected into the container 10.

ていることが判明した。By the way, the diameter of peeling rolls 1 and 1 is 12ψ, the outer diameter of feed roll 2 is 30ψ, the same length is 30011111, and the rotation speed of each roll is 300 r, p, i, and 200 per hour.
When I peeled 1 kg of grapes, almost 100 kg of grapes were peeled.
% I was able to completely peel the skin without crushing it. This was found to be much better than the conventional equipment, which processed 30 to 40 kg per hour and resulted in about 10% of the water being soaked.

てもよい。In addition, a pair of peeling rolls 1, 1 and one feed roll 2
If a plurality of these sets are installed in parallel with 14 (1), a large amount of grapes can be peeled at the same time, and the number of sets to be installed can be selected appropriately according to the amount of grapes to be processed.
Only the input section 6 on the grape supply side may be provided, and the discharge section 7 may not be provided, and the scrapers 8, 8 may also be used at the lower end of the hopper 4, or a dedicated scraper may be provided separately.
また、ロール１．１はその表面部をゴムのような弾性の
ある部材で構、成することもでき、その場合には弾性部
材で構成しないときと較べ、ぶどうの皮の挾み込みを一
層円滑にすることができる。In addition, the surface of the roll 1.1 can be made of an elastic material such as rubber, and in that case, the pinching of the grape skins is more easily achieved than when the roll 1.1 is not made of an elastic material. It can be made smoother.
さらに、ロール数の直径・回転数について一般的に好ま

〜１２０ｒ、ｐ、ｍ程度が好ましい。Furthermore, generally preferred conditions regarding the diameter and number of rotations of the number of rolls are as follows: the pair of rolls 1.1 for peeling have a diameter of 10 to 20 ψ and a number of rotations of 200 to 350 r, p, m.
sThe feed roll 2 has a diameter of 20 to 40ψ and a rotation speed of 70.
About 120 r, p, m is preferable.

きる。As explained above, according to the present invention, the grapes on the pair of rolls are pushed between the pair of rolls while being fed by the spiral protrusion of the feed roll, and the skins are properly sandwiched between the rolls to peel the grapes. This makes it possible to substantially eliminate crushing of the grapes and significantly increase the yield.

することができる。Further, as in claim 2, if the hopper is provided on the side where the peripheral surface of the feed roll rotates downward, the grapes in the hopper are scraped downward by the spiral protrusion as the feed roll rotates. As a result, the grapes on the pair of rolls are automatically sent to the discharge side by the spiral protrusion into the gap created. Furthermore, by providing a scraper along the outer surface of the peeling roll, peeled skins are prevented from adhering to the circumferential surface of the peeling roll (and interfering with the transport of the grapes), and the scraper is placed at the end of the feed roll. If a scraping member is provided, the grapes on the peeling roll can be collected using the rotation of the feed roll.
