Description

Jeonggok device {GRAIN POLISHING APPARATUS}

The present invention relates to a grain, a rice mill and a grain sorting device.

As a method of removing the bran from the outer periphery of the grains attached to the bran around, there is a method of combining the grinding method of grinding the grain around, the friction type to rub the grains rubbed treatment, both methods.

Then, in the friction type, there is also a method of polishing the rice while transferring the introduced rice or the like by using a structure having a spirally rotating abrasive body. Alternatively, it can be classified into a wet method using water and a dry method using air.

Next, in the conventional rice milling device, it is difficult to remove mixed rice such as waste from the processed rice and the like in the same rice milling process, and there is also a method of interlocking with the attached waste removing device.

In both grinding and friction, temperature rise cannot be avoided, the quality of the grains may change and affect the taste, or there is a possibility that a bee or bacteria may occur.

In the wet method, the supplied moisture penetrates into the grains unnecessarily, or the moisture is added to the inside and outside of the apparatus to harm the food, and at the same time, the food taste is also reduced. There is also a problem that the separated bran contains water.

In the dry method, such a problem is small, but depending on the structure, the surface of the grains is rubbed, and thus, problems such as changes in the taste of foods due to high temperatures, occurrence of insects, oxidation of bran remaining in small amounts, deterioration in preservation, etc. There is also.

In grains, it is known that excessive pressure should not be applied to the work of cutting or polishing the surface.

In the whole grains, in the state before final processing, the substance which covers the surface is hard, except for rice (in the case of brown rice).

Therefore, as for other grains, the process (epidermis removal) by the apparatus before eating is by cutting. Since rice (brown rice) is a light skin material, there is a process of removing the skin (bran) by pressure, but cutting with light pressure is effective for obtaining quality. An object of the present invention is to remove the surface (epidermis) of grains without applying such excessive pressure.

With a rotary cutting body (hereinafter referred to as a cutting body) in which a plurality of rotary plates having a plurality of blade functions are overlapped and combined, as a process, the main speed is gradually increased from the input of grains to the discharge, uniformly and at a cutting temperature. It is a method of removing the epidermis of grains without raising the level. In addition, with respect to conventional rice milling machinery, since the whole apparatus is a large structure, its size was large, but in the structure of this invention, it is possible to perform a more compact design, and it is economical and maintenance point. It is possible to carry out at low cost and easily.

Next, since the rotary cutting body of the present invention is not an integrated abrasive body of a conventional spiral structure but is an independent ring shape, the shapes of the cutting parts are independent of each other, and the production and replacement of parts are easy, and the cost down ( It is also possible to achieve a cost down.

And by making the space | interval of each rotary cutting body and an outer mesh part movable, it becomes possible to ensure the space according to each input grain.

Next, in order to achieve the above object, it is possible to change the spacing of each rotary cutting body by changing the thickness of a plurality of spacers provided between the rotating bodies in response to the grains introduced. To achieve the object of the present invention.

EMBODIMENT OF THE INVENTION Hereinafter, the Example of this invention is described with reference to drawings.

As shown in Fig. 5, the grain-setting apparatus of the present invention integrates the inlet hopper 20, a series of processes from the product input to the cutting, polishing, separation processing process, discharge ports such as bran, and the discharge of the treatment product. It is comprised by the combination of the some unit part, the discharge port 23 of an input product, and the motor part 26 for driving each unit.

Each unit part is coupled up and down by the unit junction part 22. However, the junction with the inlet hopper 20 is connected to the upper shaft fixing part 21. The discharge ports such as the bran provided in each unit are connected to the suction duct 24, are transported and sucked in the direction 25 such as the suction fan, and accumulated.

Next, the detail of each unit part is demonstrated with reference to FIG.

In the structure of each unit, unprocessed grains fed from the inlet 8 are conveyed to the lower end by the spiral feed roll 2, and the cutting rotary blade 4 and the outer net which rotate by the central axis 5 It is cut and polished while passing through the gap of 3).

Between each cutting rotary blade 4, the clearance gap is provided by the spacer 11, and the clearance gap is provided from the air duct 6 side between the ventilation hole 10 and the outer mesh 3 through the clearance gap. Aspirated air flows. Due to this effect, the cut, polished bran and the like are sucked off through the outer mesh 3.

Next, the width | variety of the space | interval between the rotating body which consists of the several cutting rotary blade 4, and the outer pole 3 is conveyed up and down by the mesh position adjusting lever 1, and is fluctuate | varied. It is also possible to adjust an appropriate interval for each unit according to the kind and size of grains introduced.

The product subjected to the processing is moved to the outlet 7 while rotating down, and then to the next unit or outlet 23 connected by the coupling 9. In addition, the arrow in which the air flow 12 shown in FIG. 2 shows the flow of air drawn in and to the air duct 6 is shown.

In Fig. 3, the unprocessed rice in the state in which the waste is mixed is taken as an example, and the unprocessed rice 13 is introduced into the unprocessed rice 13, and the waste 15 and the processed rice 14 are separated. It is an expression.

Next, the detail of the cutting rotary blade 4 is demonstrated in FIG.

The planar portion of the cutting turn plate 16 has a single or a plurality of ventilation holes 18, a central axis hole 17 is provided at the center thereof, and the plurality of cutting turn plates 16 have subtle circumference sizes. Different, and their area is superimposed in the order of conical shape to form a rotating body. At that time, the spacer 11 is provided between the cutting rotary plates 16, so that air flows from the ventilation hole 18. As shown in FIG. The cutting rotary plate cross section 19 is a cross-sectional view of the cutting rotary plate 16.
