Description

[0001] Grain pulverization machine [0002]

The present invention relates to a grain grinding apparatus, and more particularly, to a grain grinding apparatus capable of grinding grain into a dry state while reducing heat generated during grain grinding.

The westernization of the eating habits led to a significant decrease in rice consumption by the people and a sharp increase in the stock of rice, resulting in a serious problem such as a decrease in the income of the farming village.

Therefore, in order to solve these problems, researches have been conducted on methods for promoting rice consumption. Among them, R & D on processed foods using rice has been concentrated.

In particular, it is easy to develop food by using rice as raw material rather than using it in the form of rice flour, instead of pulverizing rice and transforming it into a rice flour having fine particles.

Therefore, in order to produce processed foods using rice, it is necessary to crush the rice grains to have fine particles and make them into rice flour.

Conventionally, in order to make rice flour, the rice was called water for a certain period of time, and then the two rollers, which are in contact with each other in a pair, mainly used a wet grinding method in which rice is crushed by squeezing rice called water.

However, such a wet grinding method requires a relatively large grinding cost as compared with a wheat flour produced by a dry grinding method, and it is difficult to finely grind the rice so as to have fine particles in a wet state, and the workability of food is also very low Has occurred.

In addition, the pinhole grinder mainly used in the dry milling method has a problem in that the longer the milling time is, the more heat is generated due to the friction between the air and the fin, and the temperature of the pulverized rice flour rises together with the nutritional damage of the rice flour Problems such as loss occurred.

The present invention relates to a grain grinding apparatus which is used for pulverizing grains into a dry form and reduces frictional heat generated during grinding of the grain to reduce the nutrient loss of the pulverized grain flour.

The present invention will be described in detail with reference to FIG.

1 is a perspective view of a grain grinding apparatus according to an embodiment of the present invention.

1, a grain grinding apparatus 100 according to the present invention includes a hopper 110, a feed adjusting unit 130, a crushing unit 150, a discharging unit 170, a suction fan 180, 190).

The hopper 110 is placed on the table 101 and has an annular abstract shape with one of its mouths larger than the other, so that the grain g to be crushed is introduced.

The supply regulating unit 130 is disposed at the lower end of the hopper 110 and feeds the amount of the grains g falling from the hopper 110 into the crushing unit 150 to crush the grains g To be controlled uniformly.

The crushing unit 150 is located at a lower portion of the feed adjusting unit 130 and rotates the grain fed from the feed adjusting unit 130 as the disk-shaped impeller having a plurality of crushing fins protruded therein is seated and rotated Crush it.

The discharge unit 170 extends from one side of the crushing unit 150 and discharges the crushed powdered grain in the crushing unit 150 to the outside.

The suction fan 180 is connected to the end of the discharge unit 170 in a communicative manner to suck the pulverized powder of the grain g discharged from the discharge unit 170 and then transfer the pulverized powder to an external storage device.

The control unit 190 controls the rotation speed of the impeller 157 rotating for crushing the grain g and the amount of the crushed grain of the feed adjusting unit 130 for the grain g to be crushed And transmits the generated control signal to the impeller 157 and the supply controller 130, respectively.

Hereinafter, the supply controller 130 will be described in more detail with reference to FIG.

Fig. 2 is a cross-sectional view of the supply control section in the grain grinding apparatus of the present invention. Fig.

2, the feed regulating section 130 in the grain grinding apparatus of the present invention includes a shut-off bar 132, a feed roller 134, a roller drive motor 136, and a guide bar 138. As shown in FIG.

The shut-off bar 132 is positioned between the lower end of the hopper 110 into which the grain g is introduced and the upper portion of the shut-off bar holder 133 and moves downward in the horizontal direction, Whether the grain (g) is crushed or not is determined. That is, in order to crush the grain present in the hopper 110, the blocking bar 132 slides in the outer direction of the hopper 110 to open the lower end of the hopper 110, And the grains present in the hopper 110 are dropped into the supply controller 130. If the crushing of the grains dropped in the previous operation is not completed or the crushing of the grain is not desired, the blocking bar 132 slides inward of the hopper 110 to move the hopper 110, The grains in the hopper 110 do not fall down. And is present in the hopper 110 as it is.

Particularly, at this time, by adjusting the slide movement time of the cut-off bar 132, the amount of the grain falling to the supply control part 130 can be roughly adjusted.

For example, when the shut-off bar 132 slides in the outward direction of the hopper 110 and slides backward in the hopper 110 after 5 seconds, It is assumed that the amount of the grain falling to the supply regulator 130 is about 200 g. If the blocking bar 132 slides in the outward direction of the hopper 110 and slides backward in the hopper 110 after about 3 seconds, Is about 120 g. That is, when the lower end opening time of the hopper 110 is reduced from 5 seconds to 3 seconds by 2 seconds through the cut-off bar 132, the amount of the grain g falling into the feed adjusting part 130 is 200 g 120g can be reduced by about 80g.

In addition, the slide movement period of the shut-off bar 132 can be set in advance by the control unit 190. In this case, a large amount of grain g is first introduced into the hopper 110, and then the controller 190 moves the shutting bar 132 in accordance with a predetermined slide movement period of the shutting bar 132 And transmits the generated control signal to the shut-off bar 132. Accordingly, in response to the control signal received by the shut-off bar 132, the grains in the hopper 110 can be automatically and periodically dropped to the supply regulator 130. Accordingly, no separate labor force is required for starting the grinding of the grain (g).

The feeding roller 134 is located at a lower portion of the blocking bar 132, that is, at one side of the fixing frame 139 positioned between the lower portion of the blocking bar 132 and the table 101, The amount of pulverization of the grain g to be supplied to the pulverizing unit 150 is finer than the amount of pulverization using the blocking bar 132 and then the adjusted grain g is discharged through the roller outlet 137. For example, if the blocking bar 132 controls the amount of grain crushing in units of 40 grams per second, the feed roller 134 can finely control the amount of grain crushing in units of 1 to 5 grams per rotation angle.

That is, it is determined whether or not the grain g existing in the hopper 110 is crushed through the blocking bar 132 and the amount of the grain g to be crushed is roughly adjusted, The amount of the grain g to be crushed can be controlled more precisely.

The roller driving motor 136 is located on the other side of the fixed frame 139 and receives the control signal generated from the control unit 190 and accordingly transfers energy to the feeding roller 134, 134).

The guide bar 138 is located at the lower end of the feed roller 134 in one side of the fixed frame 139 and rotates the feed roller 134 so that the grain g finely- (150).

By controlling the amount of the cereals g to be introduced into the crushing unit 150 through the shut-off bar 132 and the feed roller 134 in the supply control unit 130 to be constant, A uniform load is also applied to the crushing drive motor for rotating the crushing drive motor. Accordingly, it is possible to prevent the crushing drive motor from overheating, thereby preventing the internal temperature of the crushing unit 150 from increasing.

Hereinafter, the crushing unit 150 in which the crushing of the grain is substantially performed will be described in detail with reference to FIGS. 1 and 3 to 5 described above.

FIG. 3 is a perspective view showing the internal structure of the container before the impeller is mounted, FIG. 4 is a plan view of the crushing unit in which the impeller is seated in the container, and FIG. Fig.

The crushing unit 150 includes a container 151, a cover case 153, an inlet 155, an impeller 157, and a crushing drive motor (not shown).

As shown in FIG. 3, the container 151 has a cylindrical shape in which the inside is hollow and a part of the inside surface is connected to the discharge part 170. The container 151 surrounds the inner side and has a plurality of concave and convex grooves 151a. The container outlet 151b is opened in a curved shape on a part of the inner side connected to the discharge part 170, A sieve net 151c is inserted into the container outlet 151b in an opened state to separate the pulverized grain according to the particle size and discharge it to the discharge portion 170. [ 3, the container outlet 151b is formed only on a part of the upper surface of the inner surface connected to the discharge unit 170, A plurality of uneven grooves 151a may be formed to continuously surround the inner surface. That is, a container outlet 151b is formed at the upper part of the inner side surface of the container 151 connected to the discharge part 170 and a plurality of uneven grooves 151a are formed at the lower part, The area that can collide with the plurality of recessed grooves 151a is further widened, and the grain can be more finely crushed. In addition, the crushing is completed, and the grain, which is light in weight, can be easily discharged to the outside through the container outlet 151b.

In particular, the plurality of concave and convex grooves 151a formed on the inner surface of the container 151 may be formed in a linear shape as shown in FIGS. 3 to 4, or may be formed in an oblique shape as shown in FIG. And may also be formed in a spiral form.

The cover case 153 is engaged with one side of the container 151 and the grains falling from the supply control unit 130 are inserted through the inlet 155 formed at the upper center, Cover or open.

The impeller 157 has a plurality of crushing fins 158 protruding from the surface thereof. The impeller 157 is mounted on the center of the inner side of the container 151 and then rotates to crush the input grains. That is, when the impeller 157 rotates, a strong rotating air current is generated inside the container 151. At this time, the inside of the container 151 through the inlet 155 of the cover case 153, A crushing pin 158 formed on the impeller 157 while moving along the generated rotary flow of the cereal g introduced into the upper part of the container 157 and a plurality of uneven grooves 151a ), The grain of the grain is finely pulverized.

The crushing drive motor (not shown) is located below the container 151, that is, inside the table 101 shown in FIG. 1, and rotates the impeller 157. The crushing drive motor receives a control signal for controlling the rotational speed of the impeller 157 from the control unit 190 and generates a power corresponding to the received control signal and then transmits the power to the impeller 157, 157 can be rotated.

In particular, the impeller 157 may have a plurality of crushing pins protruding outward from the center of the disk in at least one of oblique, straight, and curved shapes. Hereinafter, referring to FIGS. 6 to 11, The various structures of the controller 157 will be described in more detail.

In the first embodiment of the impeller 157 shown in FIG. 6, a plurality of the crushing fins 158 may protrude outwardly from the center of the disk in a diagonal shape, And can be inclined toward the center of the circular plate.

In the second embodiment of the impeller 157 shown in FIG. 7, a plurality of the crushing pins are divided into separate groups such as the first crushing fin portion 158a and the second crushing fin portion 158b, respectively have.

The first and second crushing fin portions 158a and 158b may protrude obliquely or linearly so that a plurality of crushing pins 158a surround the center of the circular plate. A plurality of crushing fins 158b may be formed in a curved shape so as to surround the first crushing fin portions 158a at a position spaced a predetermined distance apart from the crushing fin portions 158a. In this case, the height and length of the first crushing fin 158a may be different from the height and length of the second crushing fin 158b. In particular, The height of the first crushing fin portion 158b may be higher than the height of the crushing fin portion 158b and the length of the first crushing pin portion 158a may be narrower than the length of the second crushing pin portion 158b.

7 shows a state in which the impeller 157 according to the second embodiment including the first crushing fin 158a and the second crushing fin 158b is seated inside the container 151 8.

FIG. 8 is a perspective view showing the impeller of FIG. 7 of the present invention seated in a container.

8, an impeller 157 according to the second embodiment is seated in the center of a cylindrical container 151, and then a predetermined amount of grain g from the feed controller 130 is supplied to the impeller 157 157, the impeller 157 is rotated by the power transmitted from the crushing drive motor. Thus, a rotating airflow is generated on the impeller 157, and the introduced grains g move around the inside of the container 151 by the generated rotating air current. That is, the grains g collide with the first crushing fin portion 158a and the second crushing fin portion 158b formed on the surface of the impeller 157 while the grains g move by the rotating airflow, The concave / convex groove 151a is formed to surround the inner surface of the container 151, and the concave / convex groove 151a is continuously collided with the concave / convex groove 151a.

Therefore, the grain size is significantly reduced and finely crushed each time the grain g collides with the first crushing fin portion 158a, the second crushing fin portion 158b and the irregular groove 151a. Particularly, when the grain (g) impacts on the second crushing fin portion (158b) formed in a curved shape on the impeller (157), a larger centrifugal force acts on the grain (g).

Therefore, when the same number of revolutions and the same rotation time as those of the impeller according to the first embodiment described above are compared with each other, the impeller according to the first embodiment rotates at the same time and the same number of revolutions, The grain (g) can be crushed quickly.

Further, another structure of the impeller 157 described above can also be confirmed from FIG. The structure of the impeller 157 shown in FIG. 9 may be formed such that each of the crushing fins 158 protrudes in a curved shape toward the outer edge of the circular plate at a position spaced apart from the center of the circular plate by a predetermined distance.

9, the plurality of pulverizing pins are not classified into various groups such as the first pulverizing fin portion 158a or the second pulverizing fin portion 158b, but also the plurality of pulverizing pins corresponding to one kind 7 to 8 in that the fin does not protrude obliquely or linearly while coming into contact with the center of the disk.

The third embodiment of the impeller 157 shown in Fig. 10 has the crushing pin 158 formed on the impeller 157 so as to protrude outward from the center of the disk in a linear shape, The length of the impeller 157 is shorter than the length of the impeller 157 according to the first embodiment. Therefore, the grain g put on the impeller 157 passes through the central portion and the outer frame portion of the impeller 157 by the rotating air current generated by the rotation of the impeller 157, and rotates more rapidly, Crushing fin or crushed groove and crushed finely.

The crushing unit 150 may further include a crushing lid 159. In this case, the crushing lid 159 has a hole at a position corresponding to the center of the impeller 157, (Not shown). At this time, the guide bar 138 of the supply control part 130 is positioned on the upper part of the hole, and the grain g is put into the container 151.

A crushing lid 159 may be seated on the container 151 to cover the upper surface of the container 151, as shown in FIG. In the case of the impeller 157 according to the fourth embodiment as described above, when the impeller 157 seated inside the container 151 is rotated by the crushing drive motor, And the grains existing on the impeller 157 are piled up and rotated by the rotating airflow. At this time, the grinding fins 158 protruding on the impeller 157 and the grains g continuously collide with the plurality of recessed grooves 151a formed on the side surface of the container 151, and the particles are finely divided. Particularly, at this time, the grains g are rotated by the strong rotating air current generated by the rotation of the impeller 157, so that a part of the grains g can be released to the outside of the container 151 by the centrifugal force. However, when the crushing lid 159 is placed on the upper portion of the container 151, the upper surface of the container 151 is closed so that the grains g are prevented from escaping to the outside, To obtain the grain flour for the same amount of grain as the initial amount of the grain put into the crushing section 150. [

In addition, in another embodiment of the impeller 157, a plurality of the crushing fins 158 may protrude outward from the center of the disk in the shape of a crescent moon.

As described above, experiments were conducted to examine how the impeller having various structures affected the internal temperature of the container and the nutrients contained in the grain.

In this experiment, rice was pulverized with different number of revolutions for four impellers having different structures, and the water content of the pulverized rice, the internal temperature of the container, and the starch damage of the rice were measured respectively. The measurement results are shown in Table 1 below.

※ Moisture content of raw rice: 15%, (): Ambient temperature, Filter: 200mesh (74㎛) Raw white rice: 37.9

That is, in this experiment, the first experiment was carried out by rotating the impeller having the structure described in FIG. 6 at 4000, 4500, and 5000 rpm at different rpm, and the impeller having the structure described in FIG. And the second experiment was carried out. The third experiment was carried out by rotating the impeller having the structure described in FIG. 10 at different revolutions per minute. Finally, the fourth experiment was carried out by rotating the impeller having the structure described in Fig. 11, in which the crushing lid was disposed on the impeller having the structure described in Fig. 7, at different revolutions per minute.

Hereinafter, the first experiment showing the best experimental results among the four experiments in accordance with the respective structures of the impeller will be described in detail.

As shown in Table 1, the impeller having the same structure as described in FIG. 6, that is, a plurality of crushing plates protruding outward from the center of the disk in a diagonal shape, is manufactured by the crushing drive motor The water content in the grain is 12.40%, and the internal temperature of the container 151 is 43 ° C. At this time, the starch damage degree of the rice present in the container 151 Is 12.58%.

However, when the impeller 157 having the same structure is rotated at 4,000 rpm to 4,500 rpm and rotated, the water content is 12.55%, the internal temperature of the container 151 is 37 ° C, the starch damage degree is 12.85% .

When the impeller 157 having the same structure is rotated at a revolution rate of 5,000 rpm per minute, the water content of the pulverized rice is 12.04%, the internal temperature of the container 151 is 34 ° C, and the starch damage degree is 11.51% .

As a result, when the rice is pulverized by changing the revolution speed per minute to 4,000 rpm, 4500 rpm and 5000 rpm for the impeller 157 having the structure shown in FIG. 6, the pulverized rice at 5,000 rpm has a relatively high water content The inner temperature of the container 151 is the lowest, and the starch damage of the crushed rice is also lowest.

As described above, according to the grain grinding apparatus according to the present invention, since the grains are crushed in the dry state, the grinding amount can be controlled more precisely than in the case of grinding in the wet state and the grain can be crushed finely And the food processing ability of the grain can be further improved.

In addition, according to the grain grinding apparatus according to the present invention, the amount of the cereal to be introduced into the crushing unit is controlled to be constant through the supply control unit, thereby reducing the overheating of the crushing drive motor and reducing the generation of frictional heat generated in the crushing unit, The nutrient reduction phenomenon of the crushed grain powder can be prevented in advance.
