Manufacturing Method of Rice Bran Pellets and Molding Apparatus of Rice Bran Pellets for Use {MANUFACTURING METHOD OF RICE BRAN PELLET AND FORMING DEVICE OF RICE BRAN PELLET BEING USED IN THE SAME}

The present invention relates to a production method for pelletizing a rice bran used as a weeding method for removing only weeds without harming rice and a molding apparatus for rice bran pellets used therein.

In recent years, rice bran has been used as a method for removing only weeds without harming rice. This is because when plant-based organic fertilizers such as rice bran or oil foil used as organic fertilizers are used in the soil as they are living, they are germinated and grown in the organic acids generated when decomposed by microorganisms. On the contrary, the method is used to suppress germination and growth of weeds.

The weed suppression effect of surface use such as rice bran is still unknown, but when rice bran is sprayed, microorganisms multiply rapidly by feeding it, and the surface layer of the soil is temporarily reduced (oxygen deficiency). It is said that weed suppression action is particularly strong due to acidification of the soil surface caused by mass generation and rooting inhibition effect by organic acids such as lactic acid. In addition, when organic acids are decomposed to increase sugars and amino acids, seaweeds, Bupyeongcho, etc. are generated, and it is also shown that weeds are suppressed by the light shielding effect. In addition, the sprayed rice bran is continued to ferment slowly, and has the effect of one stone two trillion to eventually become an organic fertilizer without defects in the growth of rice.

The use of rice bran is generally performed immediately after or at the same time as a conventional rice plant, and as a method of use, rice bran is introduced from the water inlet as it is in a powder state or sprayed using a spreader or the like. At present, the use of rice bran continues to increase, and its effect is highly evaluated.

Test implementation of rice bran in rice farming continues to expand, but its use is selected as a method of spraying the rice bran as it is in the powdered state, so as to spread it as uniformly as possible throughout the paddy field. Although it may be pushed by the after-scattering wind and it is difficult to make it into a uniform state, it is also used to apply and spread rice bran to wet crumb rice. In addition, in the method of introducing rice bran from the water inlet, the rice bran is made by using as much dried oil as possible, and selecting and performing the day when there is no wind or when the breeze is blowing from the water inlet toward the tip of the water. It is a cumbersome task to introduce half the amount of rice bran without seeing it in a large amount at a time.

The present invention, in the conventional rice bran spraying, a large amount of spraying and labor problems, easy to spread the dispersion by the wind, etc., rice bran dispersed throughout the paddy field, dissolved oxygen is reduced to the small animals of Munon In order to improve this problem, it is possible to use a power spreader by pelletizing the powder of rice bran to enable simple and uniform spraying, and also to influence the wind. It is an object of the present invention to provide a rice bran pellet manufacturing method and a small, low-power rice bran pellet molding machine for use in which rice bran pellets can be used simply, reliably and efficiently without being received.

MEANS TO SOLVE THE PROBLEM The present inventor has repeated research in order to achieve the said objective, However, by pelletizing a rice bran, it discovered that the reduction of spreading effort can be aimed at, and uniform spreading can be realized, and the manufacturing method of an effective rice bran pellet and The present invention has been successful in the development of an apparatus which can be easily and reliably formed in a small pellet to be used.

The manufacturing method of the rice bran pellet of this invention makes the rice bran produced | generated by rice milling (spring aging, storage bran etc. over time) into a main material, adding water to this, stirring-mixing, and shape | molding this mixture in pellet form It consists of a process and the process of drying this molded object.

In forming the rice bran into pellets, the rice bran itself becomes harder to be hardened by its components. Therefore, it is necessary to add water to the rice bran to adjust the rice bran to a predetermined moisture content, and the moisture and oil in the rice bran form a combination. Can be realized. The water content of the rice bran necessary for molding the pellets is about 25 to 35%, more preferably about 30%. In the case of using raw bran as rice bran, since the oil content is contained about 20% by weight, the water to be added is preferably 15 to 25% by weight, preferably 20% by weight with respect to 100% of rice bran. When the water content is low, the effect of the combination of water and oil is low, and it is difficult to form a solid form, and the pellet forming machine also requires a large amount of power and cannot be miniaturized. On the other hand, if the moisture content is too large, the formed pellets themselves are fragile and the pellet shape cannot be maintained, and time is required for drying. In this step of stirring and mixing, it is necessary to add water to rice bran and mix it uniformly as a pre-work of pellet molding, and the moisture content of the mixed rice bran is an important point in pellet molding. In particular, in the case of pelletizing the raw bran, since the oil bran is contained in the rice bran, even if water is added, it is not a uniform pellet material if it is not stirred well.

In addition, in the present invention, in place of the above water, a soybean squeezed soybean containing a large amount of water (for example, sulfa vegetable is referred to as hereinafter) can be used. In this case, the mixing ratio of rice bran and bean curd is added to the rice bran by 40 to 50% by weight so that the water content of the mixture of rice bran and bean curd is about 25 to 35%, preferably about 30% as described above. Adjust

In the method of the present invention, about 5 to 20% by weight of a vegetable solid accelerator (coupling agent) can be added to the rice bran. Thereby, it becomes harder than the pellet shape | molded only by rice bran. As the coupling agent, flour, rice flour and the like are common. In addition, when pellet-forming what mixed the rice bran and the vegetable coupling agent, the water content of 10 to 25% by weight is suitable with respect to the mixture of a rice bran and a coupling agent. Thereby, the water content of the mixture with the linking agent is adjusted to 25 to 35%.

Rice bran and water or busy paper are mixed uniformly using a mixer or the like. Insufficient mixing may cause clogging in subsequent compression molding, or nonuniformity may occur in the bonding of the powder particles of the bran, and the predetermined molding pellets may be brittle. The mixer may be, for example, a vertical type in which a stirring blade is projected on an upright rotating shaft, a horizontal type in which a stirring blade is provided on a horizontal axis, or a mixing mixer of a type in which a stirring blade is provided in a rotating body. Although it uses, it is not limited to this.

Rice bran added with water or a mixture of rice bran and bean curd, or a mixture of rice bran and vegetable added with water (hereinafter referred to as rice bran) is then sent to the molding process. Generally as a molding apparatus, an extrusion type (compression extrusion type) or a mold type type thing is used, but in this case, it is good to use an extrusion type which gives strong pressing force to rice bran and the like. As the extrusion type molding apparatus, since the rod-shaped pellet material is continuously extruded, the pellet molded article can be obtained by using an apparatus provided with a means for cutting this into a required length. The size of the pellet molded article may be 4 to 6 mm in diameter and 5 to 8 mm in length if sprayed by hand. However, in order to be able to sprinkle it in the spreader, it is 4 to 5 mm in diameter and 5 to 6 in length. It is desirable to be about mm

The pellet molded product taken out from the molding machine is subjected to the drying process since the fermentation starts when left as it is. In addition, it solidifies into pellets of hardness suitable for spreading and, at the same time, enables long-term storage. A drying process can be performed by a conventionally well-known method. For example, it may be natural drying in the sun or natural drying in the house, and may be performed using a dryer such as a balance dryer or a rotary kiln dryer. It is preferable to make the drying into about 10% of moisture content. After drying, the rice bran pellets can be stored in a non-breathable bag, and can be taken out and sprayed as necessary.

Next, embodiment of the shaping | molding apparatus of rice bran pellet is described. In particular, this apparatus has a configuration suitable for farmhouses or the like to produce rice bran pellets by itself, Figs. 1 and 2 show an embodiment of the apparatus, and Fig. 3 shows another embodiment.

1 and 2, 1 is a gas formed in a box shape, in which a supply part 2 such as rice bran and a pellet forming part 3 are arranged. The pellet molding part 3 has a pitch at the rear end side of the rotating shaft 9 in the transfer cylinder 5 in which the disk 6 having a plurality of extrusion holes 7 is detachably attached to the front end. The spiral feed blade 10 for coarse feed and the press screw 8 which protruded and provided the spiral blade 11 for fine press on the front part side are arrange | positioned, and the front end part of the rotating shaft 9 from the disk 6 is arrange | positioned. It protrudes and the base end of the rotating shaft 9 is connected with the motor 12. As shown in FIG.

And the spring which the cutter 13 which contacts with the knob 14 and rotates simultaneously with the rotating shaft 9 is joined to the part which protruded from the disk 6 of the rotating shaft 9 at the outer surface of the disk 6. It is provided in the state in which the pressure contact force was maintained by the action of (15). Moreover, the supply port 16 which communicates with the supply part 2 is provided in the upper side of the back part of the conveyance cylinder 5, and is open. As the means for maintaining the pressure welding force of the cutter 13, an elastic rubber or the like may be used instead of the spring 15. In addition, the pressurized spiral blade 11 can be formed by two sets of windings. As a result, the rice bran and the like in the pellet-forming portion 3 are pressurized by the compression action of the pressurized spiral blade 11, but the axial vibration is prevented by uniformly receiving the reaction force by the two-roll winding spiral blade.

The supply part 2 is equipped with the hopper 21 and the stirring chamber 22 which falls down, The lower end part of the stirring chamber 22 communicates with the supply port 16 of the said transfer container 5, and In the stirring chamber 22, the stirring rotor 23 which protruded and provided the stirring blade 25 in the shaft lever 24 rotated by the drive of the rotating shaft 9 is installed. In the lower part of the hopper 21, a rough eye hopper net 26 for protection is provided.

In the apparatus of the said structure, rice bran etc. are thrown into the hopper 21. In this case, rice bran and the like are adjusted to a water content of about 25 to 35% necessary for molding the pellets. However, in the case of using raw bran, 20% by weight of water may generally be added to the raw bran 100. Rice bran and the like introduced into the hopper 21 exit the hopper network 26 and flow down to the stirring chamber 22. In the stirring chamber 22, the water, which is generated and added, is uniformly mixed by the rotation of the stirring rotor 23, and is supplied from the supply port 16 to the rear portion of the conveying tube 5 of the pellet forming part 3. Will be supplied. In addition, although the stirring chamber 22 was provided so that the apparatus of embodiment of FIG. 1 may be used when water is added to it using raw bran, the material, such as rice bran adjusted to predetermined water content, is used. In this case, the lower end opening of the hopper 21 can be directly connected to the supply port 16 except for the stirring chamber 22. In addition, even if the stirring chamber 22 is provided, there is no problem in using rice bran adjusted to a predetermined water content.

The rice bran and the like supplied to the transfer container 5 are sent to the portion where the spiral blades for pressure 11 have a fine pitch by the spiral blades 10 for transfer, and are mixed more uniformly by the effect of kneading. The disk 6 provided at the front end is reached. In the meantime, from the difference in the feed speeds (feeding amounts) of both the spiral blades 10 and 11, the surplus rice bran sent from the feeding spiral blade 10 and the like are returned to the supply port 16. The effect is such that rice bran and the like are mixed again and pressurized, pressed into the extrusion holes 7 in the disk 6, and are compressed into a rod shape and discharged from the extrusion holes 7 to the outside. Then, the pellets are formed into pellets of a predetermined length by the cutting action of the cutter 13 bonded to the outer surface of the disc 6. Since the said disk 6 is detachable, if several discs 6 of different diameters of the extrusion hole 7 are prepared, it can change as needed and the rice bran pellet shaped product of a required diameter can be obtained.

In the apparatus of the present invention, means for adding water to the introduced rice bran can be provided. 3 shows an embodiment thereof. In this embodiment, the spray nozzle 17 which injects water in the stirring chamber 22 is provided, and the water pipe 18 is connected from the water source (tap of a tap). And the gas pipe 18 is provided with the valve 19 located in the vicinity of the spray nozzle 17, and adjusting the water quantity. The spray nozzle 17 is preferably installed near the stirring rotor 23 where rice bran and sprayed water are easily mixed.

In this way, by providing the water-soluble means, it is possible to eliminate the use of a mixer necessary for the pre-work of pellet forming. In the apparatus of this embodiment, by carrying out rice bran etc. without interrupting supply, a pellet shaping | molding operation can be performed continuously and work efficiency can be improved. Moreover, as shown by the dashed line of FIG. 3, a water supply means is a hollow shaft which has the spray hole for the shaft 24 of the stirring rotor 23, and connects the gas pipe 18 to the shaft 24, Water can be sprayed from.

As described above, according to the production method of the present invention, water is added to rice bran to adjust the moisture content suitable for molding the pellets, which are molded into pellets using a pressurized, extruded molding apparatus, and then dried. In this case, the pelletized rice bran which can be easily handled can be produced easily and inexpensively. This makes it possible to use rice bran efficiently and effectively without being affected by weather such as wind.

In addition, by pelletizing the mixture of rice bran and bean curd, in addition to the herbicidal effect, the range of application as an organic fertilizer to supplement the organic fertilizer insufficient when only the rice bran when fertilizing together with the growth of bran widens.

In addition, by pelletizing the mixture in which the vegetable solid promoter is added to the rice bran, the pellets are hardly disintegrated even in the handling after drying, so that the pellets are hardly obtained. As a wide range of applications.

Further, according to the pellet molding machine of the present invention, by using a pressure screw provided with a coarse pitch feed spiral blade followed by a fine pitch press spiral blade, it is installed at the front end of the transfer barrel while adding dough and compression to the rice bran. Since the cutting was repeated with a cutter while feeding to the disc and extruding from the discharge hole of the disc, it is possible to reliably and efficiently manufacture rice bran pellets having a predetermined diameter and length. In addition, the device is simple in structure, small in size, inexpensive, and suitable for serving as a private container for rice bran use.
