Description

[Detailed description of the invention] Industrial applications The present invention relates to a method for molting pigeon wheat.

Conventional Technologies and Technical Issues Demand for pigeon barley has been increasing recently as a herbal medicine, tea, and other edible materials. When using it for these purposes, the outer skin must be removed and only the flesh (with a thin skin is fine) is left alone. However, since the surface of the hull of pigeon barley is extremely smooth and hard, it is impossible to remove the hull using a grain milling machine such as that used to remove the hulls of rice and wheat.

For this reason, in the past, the process of husking pigeon oats was rarely carried out in Japan, and already husked pigeon oats were often imported from foreign countries and used. Probably in foreign countries, especially in China, which is a prolific producer of pigeon wheat,
It is speculated that the shedding process is done exclusively by input.

Based on the above-mentioned background, the present invention was made for the purpose of providing a method for mechanically dehulling pigeon wheat.

Means for Solving the Problems For the above-mentioned purpose, the present inventor repeated various experiments and found that the skin can be removed by first making cuts in the hard outer skin of pigeon wheat and grinding it with a grinding roll made of a whetstone. This discovery led to the completion of this invention.

Therefore, the present invention includes a first step of making cuts in the outer skin of the wheat by passing the wheat under pressure between a pair of rotating rolled wheat rolls whose peripheral surfaces are formed into an uneven shape. A combination of a second step in which the damaged pigeon wheat is then subjected to a grinding process using a dehulling machine equipped with a grinding wheel to remove the skin, and a third step in which the peeled skin is then separated from the meat. The gist of the present invention is a method for removing the hulls of pigeon wheat, which is characterized by comprising the following steps.

Function By making incisions in the outer skin of pigeon wheat in advance in the first step, when grinding force is applied to this using a grinding roll made of a whetstone in the next step, the hard outer skin will be removed from the scratched area. It splits from the skin and easily separates from the flesh to ensure reliable molting.

Embodiments Hereinafter, the present invention will be explained based on illustrated embodiments.

In Fig. 1, A is a particle size sorter, B is a barley rolling machine for damaging the hulls of pigeon oats, C is a dehulling machine, and D
is a separator, and the pigeon wheat to be treated is sent to each of the above machines in turn to be completely dehulled.

Grain size sorting machine A divides the grain size of the pigeon oats into two types: large diameter and small diameter, in order to ensure that all the pigeon oats are transformed into husks by the next-order barley rolling machine B. It is divided into three types, and a conventionally known sieve sorting device is used. The grain size-sorted barley is divided into groups and sent to the next barley rolling machine B, where the surface of the husk is scratched.

Preferred embodiments of the barley rolling machine B are shown in FIGS. 2 to 5.
As shown in the figure, it is equipped with a pair of rolled barley rolls 1 and 2 that rotate in different directions and have uneven circumferential surfaces, and it is possible to drop and feed pigeon barley to be processed from a hopper 3 between these rolls. It is something.
One rolled barley roll 1 has a plurality of pointed annular protrusions 1a with a triangular cross section extending in the circumferential direction on the outer peripheral surface, and the other rolled barley roll 2
has a large number of pyramid-shaped protrusions 2a arranged on its outer peripheral surface. Of course, the unevenness of the outer circumferential surfaces of these double rolled barley rolls 1 and 2 is not limited to this embodiment. The processed barley Y falling and supplied from the hopper 3 passes between the rolled barley rolls 1 and 2 whose spacing is adjusted in a clamped state, so that the barley Y is formed into protruding strips 1a from both sides as shown in FIG. Pressed by the riser 2a, an incision 5 is made in the outer skin Yb as shown in FIG. 9B.
When making this wound 5, special care must be taken to properly adjust the distance between the two rolling barley rules 1 and 2 so as not to damage the meat of the pigeon barley.

Next, the pigeon wheat Y with the scratches 5 on the hull Yb as described above is processed in a dehulling machine C. This dehulling machine C
Conventionally, a grinding type rice milling machine equipped with a grinding roll made of a grindstone, which is generally used, is used. That is, as shown in FIG. 6, in this dehulling machine C, a grinding roll 7 made of a grindstone and having a feeding screw 6 attached to one end is mounted concentrically in a perforated tube 8, and a suitable amount of dehulling machine C is supplied from a hopper 9. Ru Hato Mugi Y
, a processing chamber 10 between the perforated cylinder 8 and the grinding roll 7
The grinding force of the grinding roll 7 is applied within the chamber. When treated with this dehulling machine C, the hull Yb of the pigeon wheat, which has scratches 5 previously made on the hull Yb, is cracked at the scratch 5 due to the above-mentioned grinding force, as shown in Fig. 9C. It is separated from the body part. A part of the outer skin, which becomes powdered due to the grinding, is carried to the outside of the perforated cylinder 8 by the air flow ejected from the blowhole 7a of the grinding roll 7, and is collected and discharged outside the machine. The processed material discharged from the outlet 11 of the dehulling machine C is a mixture of the pigeon wheat meat Ya and the outer skin Yb that has been peeled off from it, but only 80 to 90% of it is dehulled in one shedding process. The remaining 10% or so of pigeon wheat still appears mixed in the above mixture. Then, this mixture is passed through the next separator D to separate the meat Ya and the skin Yb.
and Hatomugi Y, which still has the outer husk.

Such a separator D, as shown in FIGS. 7 and 8, has an inclined sieve plate 12 with a large number of holes 12a that allow the permeation and fall of particles of various sizes. It is suspended from the machine frame 14 by a suspension spring 13, and is configured to be slightly vibrated by an electric vibrator 15, and the mixture of meat Ya and skin Yb that passes through and falls from the sieve plate 12 is transferred to a blower blade. 17, a known wind sorting mechanism 16 transfers the relatively large grain size Ya to the first collection port 18, and the comparatively small grain size grain Ya.
It is configured so that Ya falls toward the second collection port 19 and the skin Yb is blown away toward the exhaust port 20. By processing in this separator D, the mixture discharged from the dehulling machine C is discharged from the outlet 21 at the lower end of the sieve plate 12 for unhulled pigeon wheat Y, and the unhulled pigeon wheat Y is discharged from the outlet 21 at the lower end of the sieve plate 12, and the unhulled pigeon wheat Y is discharged from the outlet 21 at the lower end of the sieve plate 12. The Ya portion is dropped from the first and second collection ports 18 and 19, and the skin Yb portion is discharged from the exhaust port 20 and sorted into each of the above three groups. The unhulled pigeon wheat Y is returned to the dehulling machine C again and processed there again.

Effects of the Invention According to the present invention, as described above, it is possible to mechanically, reliably and efficiently perform the dehulling process of pigeon wheat, which has been difficult in the past. Moreover, the method involves simply making incisions in the outer skin beforehand and then removing the skin through a grinding and dehulling process.
In the grinding and dehulling process, the outer skin of the pigeon barley is easily separated from the meat, and there is no need to apply excessive grinding force over a long period of time. For this reason, there is no problem of the meat peeling off or the surface layer being polished off, which reduces the yield.In fact, the meat is molted in a desirable state with just a thin skin remaining on the surface, and the yield is extremely low. It has an excellent effect.
