Description

[Detailed description of the invention] Industrial application field This invention is a dust removal and polishing device for soybeans, in particular, it removes dirt from the surface with the thin skin still attached, and cleans it to the extent that washing with water is not required even when cooking. is,
The present invention also relates to a soybean dust removal and polishing device that can provide soybeans with a glossy surface and high commercial value.

Prior art and its problems Soybeans have recently been in great demand as miso, soy sauce, tofu, boiled beans, natto, soy milk, and other edible materials. When cooking or processing such soybeans,
Since it is necessary to remove dirt adhering to the surface, it is desirable to provide it in a pre-cleaned state. However, in a conventionally known grain polishing device, a grindstone roll or a brush roll is rotatably supported in a cylindrical porous dust removal cylinder, and by rotationally driving the grindstone roll or brush roll, dust is removed between the dust removal cylinder and the dust removal cylinder. If a polishing device is used, the surface of the soybean may be damaged or the thin skin may be peeled off, resulting in a decrease in product value. Therefore, in the past, it was decided to wash them with water, but such washing was not only troublesome but also required a large amount of water, and there was a problem in that it produced dirty water and polluted rivers and the like.

This idea was made in view of the above-mentioned problems, and it is a dust removal and polishing device for soybeans that can remove dirt and cleanse the surface of soybeans with thin skins attached, as well as add luster and improve product value. This is what we intend to provide.

Means for Solving the Problems In order to achieve the above objectives, the inventor of the present invention utilized his extensive experience and knowledge regarding grain polishing, etc., and conducted various experiments and research. He discovered that by polishing, it was possible to remove dirt from the surface and polish it without damaging the thin skin, and this idea was completed.

That is, in this invention, a polishing roll 1 having a soybean feeding screw 5 at one end is pivoted concentrically within a porous dust removal cylinder 3 with a predetermined polishing gap 4 left therein, and is rotated by a rotary drive means 16. On the other hand, it is equipped with an air blowing means 12 for blowing air into the polishing gap 4, and an air suction means 13 for forcibly sucking the air inside the porous dust removal cylinder 3 to the outside. The gist of the present invention is a dust removal/polishing device for soybeans, characterized in that the peripheral surface of the polishing roll 1 is covered with a silicone resin layer 1a.

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

The soybean dust removal/polishing device according to this embodiment has a configuration roughly similar to that of a conventionally known grain polishing device.

In FIG. 1, reference numeral 1 denotes a polishing roll, which is mounted on a rotary drive shaft 1b that is supported substantially horizontally on a machine frame 2. As shown in FIG. This roll 1 is not made of a brush or a grindstone as in conventional grain polishing devices, but has a peripheral surface covered with a silicone resin layer 1a of a predetermined thickness, as shown in FIG. .
By using a product coated with the silicone resin layer 1a as described above, it is possible to remove surface dirt and polish the soybean without damaging the surface, and the object of the present invention can be achieved. .
The roll 1 is formed into a tapered shape whose diameter gradually increases in the discharge direction, so that the soybeans can be smoothly discharged. Reference numeral 3 denotes a cylindrical porous dust removal tube arranged outside the roll 1 with a predetermined polishing gap 4, 5 a soybean feeding screw connected to one end of the polishing roll 1, and 6 facing it from above. 7 is an opening adjustment plate for the soybeans to be ground, 8 is a hopper for charging, and 9 is a dust removal cylinder 3.
a discharge port 10 formed by opening the lower part of the other end surface;
11 is the dust removal suction funnel, 12 is the outflow control plate,
is a blower, which blows air into the gap 4 from the bottom side of one end of the machine frame 2 to cool the soybeans being polished. This sent air passes through the gap 4, passes through the dust removal cylinder 3 with dirt such as dirt removed from the surface of the soybeans to be polished, and is led to the outside via the suction device 13.

The above polishing roll 1 and soybean feeding screw 5
The transmission belt 1 is connected by a pulley 14 fixed to one end of the rotary drive shaft 1b on the outside of the machine frame 2.
5, it can be rotated slowly by power from a drive motor 16.

Operation In the illustrated embodiment described above, the soybeans introduced from the hopper 8 are sequentially fed into the polishing gap 4 by the soybean feeding screw 5. Then, it is rolled or slid on the surface of the polishing roll 1 to sequentially remove dust and polish. The dirt and other dirt thus removed passes through the dust removal tube 3 together with the air flow passing through the polishing gap 4, is forcibly sucked by the suction device 13, and is guided to the outside through the dust removal suction funnel 11. On the other hand, the dust-removed and polished soybeans are sequentially discharged from the discharge port 9.

Note that until the polishing process is completely completed, the above-mentioned dust removal and polishing process is repeated multiple times as necessary, and the thin skin remains intact and does not require washing with water. It is almost completely purified and finished in a polished state.

Effects of the invention As described above, in this invention, the polishing roll 1 having the soybean feeding screw 5 at one end is connected to the porous dust removal cylinder 3.
It is configured to be pivoted concentrically with a predetermined polishing gap 4 left in the polishing gap 4 and rotated by a rotation drive means 16, and an air blowing means 12 for blowing air into the polishing gap 4, and the porous hole. This is because it is equipped with an air suction means 13 for forcibly suctioning the air inside the dust removal cylinder 3 to the outside, and the peripheral surface of the polishing roll 1 is covered with a silicone resin layer 1a. , dust removal and polishing of soybeans can be carried out continuously and efficiently. In particular, since the peripheral surface of the polishing roll 1 is coated with the silicone resin layer 1a, the soybeans are slid or rolled on the surface, so dirt and other dirt on the surface can be completely removed without peeling off the thin skin of the soybeans. Not only can it be removed, but it also gives a beautiful gloss to the surface.

Therefore, soybeans treated with the soybean dust removal and polishing device of this invention do not need to be washed with water even when used for cooking, which can improve product value, save water resources, and It is possible to prevent pollution and save on wastewater treatment equipment.
