Description

[Detailed description of the invention] The present invention relates to a raw chestnut peeling device.

Traditionally, the process of removing the skin from raw chestnuts has been done by hand.

This manual work is done by holding each raw chestnut one by one using a knife or other cutlery, which requires a large number of workers and a huge amount of time. There are disadvantages such as a high rate of loss of product value and poor minute retention.

The purpose of the present invention is to eliminate the above-mentioned conventional drawbacks, mechanize the work of peeling the skin of raw chestnuts, make it possible to perform the work with high efficiency with a small number of hands, and increase the yield rate. shall be.

Hereinafter, the present invention will be explained through illustrated embodiments.

FIG. 1 is a longitudinal sectional side view showing a schematic configuration of an embodiment of the present invention.

This skin peeling device 1 includes a rotary cutter 2 and a skin peeling body 3.
and raw chestnuts C... along the circumferential surface of the rotational force puller 2 and the circumferential surface of the skin-gripping body 3 in the axial direction).

The rotary cutter 2 and the skin cutting body 3 are formed to have the same diameter, and are arranged coaxially side by side in the figure. It is rotated once in the directions of the arrows in FIGS. 5 and 7 by a single drive device that does not have a single rotation.

The rotary cutter 2 is provided with a large number of blades 4; IJ6 around a cylindrical drum 5 at appropriate intervals in the axial and center directions.

As shown in FIG. 5, each blade 1) has a large number of cutting edges 7 projecting outward at appropriate intervals in the circumferential direction of the drum 5.

Reference numeral 8 designates central shafts protruding from both end surfaces of the drum 5.

Of course, the intervals between the rows of blades 6 and the intervals between the cutting blades 7 are designed taking into account the size of the raw chestnuts. It is preferable to set these intervals so that they can be touched.

In addition, the thickness of the cutting blade γ is limited to a certain extent, but it also makes it easier to cut into the skin, and also prevents cuts that may be made to the pulp before cutting into the pulp. In order to make it so fine that it is not noticeable, it is preferable to make it as thin as possible, as long as the strength allows.

The above-mentioned skin plowing body 3 has a central shaft 9, and a pair of circular end plates 10 and a plowing claw tool 11 fixed coaxially at appropriate intervals. Equipped with

This peg tool 11 is made of piano wire stretched across the peripheries of both end plates 10.

The spacing in the circumferential direction of both end plates of the pruning claw tool 11 is set to such an extent that the chestnuts C... will not fall from this gap.

The cutting claw tool 11 may be composed of a blade instead of a piano wire.

The conveyance device 4 is composed of a linear conveyance device consisting of a scraper conveyor, and a chute 1 for taking out the pulp with astringent skin of raw chestnuts C... from which the skin has been peeled from the conveyance terminal end.
It is equipped with 2.

The conveying device 4 divides the raw chestnuts C into several pieces between each scraper 13; straining and conveying the raw chestnuts C along the circumferential surfaces of the rotary cutter 2 and the peeling body 3. They are arranged so as to be conveyed in the direction of their axes.

Although this conveyance device 4 may be provided in any direction in the circumferential direction of the rotary cutter 2 and the skin scraping body 3, in this embodiment, as shown in FIGS. 2 and the upper half of the circumferential surface of the body 3 - particularly, the upper half of the circumference in the direction of rotation thereof is arranged to be inclined.

Reference numeral 13 is a fall prevention upper plate.

In addition, FIGS. 2 to 4 are front views of raw chestnuts, respectively.
Figure 2 shows the fruit before being dropped into the conveyor, Figure 3 shows the fruit with numerous cuts made with the rotary cutter, and Figure 4 shows the pulp with astringent skin taken out through the chute 12. show.

Next, the operation of this skin peeling device 1 will be explained.

First 1. As shown in FIG. 2, intact raw chestnuts C... are fed to the conveying device 4.

The conveyance device 4 divides the raw chestnuts C into several pieces and conveys them along the circumferential surface of the rotary cutter 2 in the axial direction thereof.

During this transportation, the raw chestnuts C... come into contact with the rotary cutter 2 under their own weight, and as shown in Fig. At the same time, his demon skin was stripped off except for the buttocks.

In this peeling process, since no force other than the weight of the raw chestnuts C to press the raw chestnuts C against the rotary cutter 2 acts, the cutting blade 7 is inserted into the pulp of the raw chestnuts C ( It rarely gets cut.

In addition, since the conveying device 4 is placed in the upper half of the circumferential surface of the rotary cutter 2 and faces toward the upper side in the direction of rotation, the raw chestnuts C are prevented from getting wedged between the conveying device 4 and the rotary cutter 2. There isn't.

Next, the skin from the butt part of the skin that was not peeled off by the rotary force pick 2 is scraped off by the skin removal body 3.

That is, while the raw chestnuts C are being fed in the axial direction along the circumferential surface of the raw chestnut peeling body 3, the raw chestnuts C are struck one after another by the raw chestnuts 11, and the raw chestnuts are crushed by this impact force. The entire butt part of the skin is removed.

Here too, raw chestnuts C... have their own weight, and the surface of the flesh with astringent skin is hardly damaged by the cracking tool 11, and Fruit pulp with astringent skin as shown in the figure is obtained.

In this way, the skin is completely peeled off from the fruit and taken out through the chute 12.

In this embodiment, in addition to the effects of the present invention described later, the following effects can be obtained.

That is, first, the above-mentioned demon skin cutting body 3 is attached to a pair of circular end plates 10.
and a central shaft 9 coaxially connecting these parts, and the piano wire stretched across the peripheries of both end plates 10 constitutes the pinning claw tool 11.
The shape of the member is simple and can be manufactured at low cost, and the entire body 3 can be made lightweight.

It is conceivable that the conveyance device 4 is divided into a portion along the rotational force puller 2, a portion along the skin removal body 3, and a portion connecting these parts. , rotate the rotary cutter and the skin cutting body so that their axes are facing the same direction.
In addition, since parts of these peripheral surfaces are arranged in a straight line, each of the above-mentioned parts of the conveyance device 4 can be configured as an integrated linear conveyance device, and the structure of the conveyance device 4 can be simplified. Can be done.

Now, as described above, the present invention includes a rotary cutter, a skin scraper, and a conveying device that sequentially transports the rotary cutter, a skin scraper, and a conveying device that transports the blade in order (along the circumferential surface of the two-rotation cutter and the circular surface of the skin scraper). Equipped with

The rotary cutter is attached to the circumferential surface of the cylindrical drum.
．． Equipped with a large number of blade rows at appropriate intervals in the axial direction,
In addition, each row of blades is provided with a large number of cutting blades that protrude outward at appropriate intervals in the circumferential direction of the drum, so that while the raw chestnuts are being conveyed by the conveying device, the raw chestnuts are peeled off by the rotary cutter. In addition to inflicting countless cuts, it is also possible to rip off the demon's skin.

In addition, since the above-mentioned Onihide Koki-dou has a large number of Koki-claw tools on its surface, the Kikichi that rotates the Onihide contact action allows the Koki-claw tools to hit the surface of the raw chestnut one after another and rotate. The remaining demon skin can be removed with a cutter.

That is, according to the present invention, the peeling work can be streamlined, a large number of workers and a huge amount of work time can be saved, and the product value is maintained at a high level because the pulp is rarely damaged. It can be done, and the minute stop is also improved.

In addition, especially when the skin of the skin is peeled using the method of the present invention without burning the skin, there is no drying of the pulp due to burning the skin, and there is a high probability that the pulp will crack due to the impact force during peeling. Since it can be made extremely low, it has the effect of further improving the minute stop.
