DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a chestnut demon bark peeling device, and more particularly, to a large amount of demon skin, which is the outer skin of chestnut used in chestnut dishes and chestnut confections, in a short time. The present invention relates to a chestnut demon peeling device that can be peeled off.

[0002]

2. Description of the Related Art In general, chestnuts are not only eaten as they are, but also used in various chestnut dishes and chestnut confections, regardless of whether they are for home use or for business use, since they have a good natural taste and flavor. The demand tends to increase year by year. However, the pulp of the chestnut that is eaten is covered with astringent skin, and the outside of the astringent skin is covered with a smooth and hard outer skin called ogre skin. In addition, a stripping operation for stripping the astringent skin is required.

[0003] Conventionally, chestnut demon peeling work is performed by manually using a knife-shaped blade to cut one piece at a time in a small amount. In places where a large amount of chestnuts are used, such as in the industry, the chestnut skin is baked in a treatment tank, a chemical solution, a method of peeling the skin, and a high temperature and high pressure is applied to the chestnut to remove the demon skin by volume expansion. How to take, after putting a lot of cuts in the chestnut bark, hook the cut and peel off the bark, a method to peel off the bark with the biting force between two rollers with a rotation difference, or There is known a skin peeling device that cuts a chestnut hull, which has been previously sorted according to size, into a polygonal shape by a cutter blade.

Further, as disclosed in Japanese Patent Application Laid-Open No. 63-98371, chestnuts are rotated in water in a treatment tank,
There has been proposed a skinning method in which the surface of a chestnut that rotates with water is cut with a cutter so as to peel off the skin.

[0005]

However, in the conventional chestnut peeling method described above, the manual peeling method is not suitable for the work of peeling a large amount of chestnuts, The method of performing the chemical treatment has problems such as burning of the pulp portion, discoloration by the chemical solution, and impairing the natural taste and flavor inherent in chestnut.

[0006] Further, in the method of peeling the chestnut due to the volume expansion, or in the method of making a large number of cuts in the chestnut bark, hooking the cut and peeling off the bark, etc., Since the pulp is apt to be severely damaged, the yield is lowered, and in particular, it cannot be used for producing chestnut confections in which the shape of the chestnut is maintained as it is.

Further, in the method and apparatus for peeling chestnuts disclosed in Japanese Patent Application Laid-Open No. 63-98371, the surface of chestnuts rotating together with water is cut with a cutter to perform the peeling operation. However, a large amount of chestnuts put in the treatment tank are not evenly peeled, and uneven skin peeling such as demon skin or astringent skin remains.Therefore, the chestnuts taken out of the treatment tank are sorted out and peeled again. There is a problem that a post-processing operation for performing the stripping process is required.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems, and a large number of chestnuts stored in a hopper are dropped by a predetermined amount at regular time intervals to form a pair of teeth having a rotation difference. Provided is a chestnut demon skin peeling device capable of efficiently processing a large amount of chestnuts without deteriorating the natural taste and flavor of the chestnut by stripping the skin and astringent skin with the teeth of the attached roller. The purpose is to do so.

[0009]

In order to achieve the above object, a chestnut demon bark peeling apparatus according to the present invention moves a hopper for accommodating a large amount of chestnuts and a shutter for dropping a predetermined amount of chestnuts from the hopper. A slide cylinder, an onikin peeling guide section that guides the falling chestnut to the onikin peeling section, and a toothed rotating drum that peels off the chestnut okinbar by a pair of left and right cutting rollers that rotate clockwise with each other. A guide tube that guides chestnuts that have been stripped of the demon down at regular intervals, a storage box that is installed under the guide tube, and a guide box that is installed inside the guide tube outside the demon skin stripping guide section It is composed of a water injection pipe and an air injection pipe provided with an injection hole for injecting water and air from above the toothed rotary drum, and a control unit for controlling the operation of each unit at a predetermined timing. .

[0010]

Based on such a configuration, in the chestnut demon bark peeling apparatus according to the present invention, except for the step of storing a large amount of chestnuts in the hopper, all the operations and operation times of each part are set according to a preset sequence. It is controlled by a computer, and is automatically controlled by an operation signal from a control unit. Therefore, unlike the conventional demon skin peeling device, not only is there no need for preparation work for sorting the chestnuts in advance according to size, but also there is no uneven skin peeling such as demon skin remaining, and moreover, the chestnuts with uneven skin peeling are eliminated. The post-processing work such as sorting and performing the skinning treatment again is not required, and the flesh after the skinning treatment is not severely damaged, so that the yield after peeling the onikin is improved.

Therefore, according to the present invention, a large amount of chestnuts stored in the hopper, regardless of size, are dropped by a predetermined amount at regular time intervals, and the chestnuts of the toothed roller having a pair of rotation differences are demonstrated. By peeling the skin, a large amount of the chestnut can be peeled without impairing the natural taste and flavor of the chestnut.

It is constituted by a control unit 40 which controls the operation of each unit at a predetermined timing.

A large amount of chestnuts contained in the hopper 2 are provided with a stirring rod or the like (not shown) so as to drop downward by a fixed amount, and are installed so as to interlock with a shutter 3a movable by a slide cylinder 3. I have. When chestnuts are clogged in the drop opening of the hopper 2, the freely movable flap 2a, which is held down by a spring, moves outward.

A guide cylinder 30 provided around the toothed rotary drum 5 has tooth bodies 20 of cutting rollers 5a and 5b for stripping the chestnut demon skin that has fallen into the demon stripping guide section 4.
A water injection pipe 13 and an air injection pipe 14 are installed so as to remove clogs and sludge clogged at the tooth tip 20a of the tooth, and are controlled so that water and air are injected constantly or intermittently.

The onskin stripping guide section 4 is provided with a shutter 6 for dropping the chestnut from which the onskin has been stripped down at regular intervals along with astringent or sludge. Is the cutting roller 5 of the toothed rotary drum 5
The shutter 6 is peeled off by a and b, and is controlled so that the shutter 6 is opened and falls into the storage box 7 after a lapse of a predetermined time.

The chestnuts that have fallen with water and sludge from the upper opening 7a of the storage box 7 are separated from water and fine sludge by a mesh-like punching board 8 installed at the bottom of the storage box 7 to remove the onikin. The stripped chestnuts are stored in the storage box 7. When an appropriate amount of chestnuts is stored in the storage box 7, the take-out lid 9 attached to the side is opened and scraped out, and moved to the next processing step. A drain pipe 10 is provided so that water, fine sludge, dust, and the like removed in the storage box 7 are discharged to the outside through the bottom opening 7b of the storage box 7.

On the other hand, a motor 11 for driving the toothed rotary drum 5 has a V pulley and a V belt set at a predetermined reduction ratio by motors 11a and 11b respectively for a pair of left and right cutting rollers 5a and 5b. It is configured to be driven to rotate clockwise through such as. Here, the appropriate rotational speed ratio of the pair of cutting rollers 5a, 5b is preferably about 1: 5, and for example, it is optimal to set 50 rpm to 250 rpm from the results of experiments.

As shown in FIG. 6, a pair of left and right cutting rollers 5a and 5b forming the toothed rotary drum 5
The disk-shaped teeth 20 are fixed to the drive shaft at fixed intervals, and are assembled into a structure in which a number of rubber rollers 5c sandwich the teeth 20. As shown in FIGS. 4 and 5, the tooth body 20 has a tooth tip 20a formed in a saw-tooth shape.

The tips 20a of the teeth 20 projecting from the outer circumference of the rubber roller 5c of the pair of left and right cutting rollers 5a and 5b are assembled so as not to be on the same rotation surface.

The rubber roller 5c is made of hard rubber, is formed into a cylinder of metal or plastic, or is formed by sticking a rubber ring to the outer surface of the cylinder. , 5b
By controlling the appropriate bouncing of the chestnut during the rotation of the chestnut, the chestnut demon skin stripping action can be effectively performed in a short time.

The relationship between the rubber roller 5c and the tooth body 20 is, as shown in FIGS. 4 and 6, for example, according to an experiment, when the outer diameter of the tooth body 20 is 110Φ, the tooth tip 20a is outside the rubber roller 5c. The optimal diameter is 1 mm to 1.5 mm. If the amount of protrusion of the tooth tip 20a is small, it takes time to peel off the demon skin. If the amount of protrusion is too large, the chestnut will jump up and the chestnut shape will be damaged. It has been found that there are disadvantages, such as a difficulty in stripping the demon skin.

In the drawing, reference numeral 15 denotes an air filter regulator for adjusting the air injected from the air injection pipe 14, which is provided with a compressor for generating a predetermined air pressure, an electric motor for driving, or a water injection pipe 13. Although a valve or the like for adjusting the amount of water to be injected is not shown, it is naturally installed at a predetermined position in the apparatus.

Next, the operation of peeling off a large amount of chestnut demon skin by the chestnut demon skin peeling apparatus 1 configured as described above will be described along the steps.

Activate the opening 3 of the shutter 3a
b. Drop a fixed amount of chestnuts downward.

The chestnuts dropped from the hopper 2 enter the demon skin stripping guide section 4. The pair of left and right cutting rollers 5a and 5b, which have already been controlled to rotate at a predetermined number of revolutions, peel off the chestnut bark. At this time,
A water injection pipe 13 is used to remove jams and sludge clogged at the tips 20a of the teeth 20 of the cutting rollers 5a and 5b.
Water and air are injected from the air injection pipe 14 in appropriate amounts.

Cutting rollers 5a, 5b of the rotary drum 5
Thus, when a certain period of time elapses after the chestnut onskin stripping action is started, the shutter 6 opens and falls into the storage box 7. The chestnuts that have fallen together with water and sludge from the upper opening 7a of the storage box 7 are separated by a mesh-like punching board 8 provided at the bottom of the storage box 7 to remove water, fine sludge, etc. The chestnuts are stored in the storage box 7. When the chestnuts stored in the storage box 7 have an appropriate amount, the take-out lid 9 attached to the side surface
