Description

Apparatus of scattering for apparatus manufacturing frozen rice}

The present invention relates to a scattering device, and more particularly, to an apparatus for scattering cooked rice that has been transferred through a conveying conveyor in a frozen rice manufacturing process without crushing the rice grains.

Generally, frozen rice manufacturing process consists of immersion process → cooking process → freezing process → packing fixing.

The immersion process is a process of dipping raw rice in water.

The cooking process is a process of cooking rice by heating the soaked raw rice.

The freezing step is a step of freezing the rice while transferring on a conveying conveyor.

After the cooking process, the rice is frozen. At this time, the rice surface is very viscous due to the gelatinization of the rice starch, so that the rice grains are attached to each other. It is formed to reduce the cooking characteristics such as prolonged cooking time and deterioration of the food, there is a problem that the taste of the rice is also lowered during thawing.

In order to solve the above problem, conventionally, the rice grains are scattered through a scattering apparatus using an emulsifier in a cooking process or a roll brush after the cooking process.

First, adding an emulsifier in the cooking process has a problem that the emulsifier itself may be harmful to the human body when ingested as an artificial chemical.

When the rice pressure is scattered by using the roll brush two to three times after the cooking process, the rice itself is crushed while being scattered, so that the texture of the rice cannot be felt after thawing and the taste of the rice is worse.

In addition, when performing the freezing process of the cooked and scattered rice immediately there is a problem that the refrigeration efficiency is lowered because the temperature difference between the temperature of the rice and the freezer is large.

An object of the present invention for solving the above problems, while using a compressed air spraying unit to efficiently scatter the cooked rice to prevent the rice grains crushed, pre-cooling before the freezing process to improve the freezing efficiency It is to provide a rice scattering device of the device.

Rice grain scattering device of the frozen rice manufacturing apparatus of the present invention for achieving the above object, the conveying conveyor for continuously supplying the grains; A roll brush installed on the conveying conveyor to scatter the grain continuously fed; And a compressed air injection unit installed adjacent to the roll brush in the conveying conveyor traveling direction and spraying compressed air to the grain disposed on the conveying conveyor to scatter the grain.

Here, the conveying conveyor may be characterized by having a mesh structure.

The compressed air injection unit may further include a cooling unit for cooling the compressed air injected into the grains.

The compressed air injection unit may further include a moisture supply means for preventing the drying of the grain.

In addition, the transfer conveyor may further include a plurality of vibrators for vibrating the transfer conveyor.

In addition, the conveying conveyor may further include a scattering prevention plate for preventing the scattering of the grain at both sides of the traveling direction of the conveying conveyor.

On the other hand, the compressed air injection unit may be installed adjacent to the transport conveyor in the advancing direction may include a camera for monitoring the scattering degree of the grain.

The compressed air injection unit may include a compressor for compressing air; An air supply pipe communicating with the compressor and delivering compressed air; And it may be in communication with the air supply pipe may include a plurality of air spray nozzles for injecting compressed air to the grain disposed on the conveying conveyor.

In addition, the plurality of air injection nozzles may be characterized in that the injection direction of the compressed air is inclined in the opposite direction to the traveling direction of the conveying conveyor.

In addition, the plurality of air injection nozzles may be installed to form a row to have a predetermined pitch in the vertical direction of the traveling direction of the conveying conveyor, the row may be characterized in that a plurality.

The air supply pipe is characterized in that an actuator for linearly reciprocating the air supply pipe is further installed.

In addition, the vibration direction of the adjacent air supply pipe may be characterized in that the opposite.

In addition, the plurality of injection nozzles may be swingable.

According to the rice grain scattering device of the above-mentioned frozen rice manufacturing apparatus of the present invention, the roll brush is used two to three times in a conventional manner including a roll brush and a compressed air spray unit along the moving direction of the conveying conveyor on a conveying conveyor. By using the roll brush only once and spraying compressed air, rather than scattering the rice, it has the effect of efficiently scattering the rice while preventing crushing of the grain of rice due to the use of the roll brush.

In addition, since the compressed air is further included in the compressed air injection unit, the compressed air is cooled before being injected, so that the rice is scattered by the compressed air and simultaneously cooled.

Therefore, the pre-cooling process may be performed in advance before the next freezing process, thereby reducing the time required for the freezing process and reducing the temperature difference between the inside of the freezer and the rice, thereby improving the freezing efficiency.

In addition, a vibrator and an actuator are further included to vibrate the conveying conveyor and to vibrate the air supply pipe, thereby improving the scattering efficiency of the rice during compressed air injection.

The separation step (S30) is to separate the rice grains from each other in order to prevent the separation because the rice grains are bound to each other using a roll brush or the like.

The separation step (S30) is because the rice surface is very viscous due to the gelatinization of the rice starch is attached to each other, which causes the rice grains to bind to each other during freezing, as well as the freezing efficiency is reduced, as well as forming rice lumps during cooking This is because deterioration of the cooking characteristics such as prolongation of cooking time and deterioration of food taste occurs, and the taste of rice also deteriorates.

At this time, it is important in terms of texture and taste of the rice after thawing so that the rice grains are not crushed while being separated.

Then, the separation step (S30) is separated from each other rice using a roll brush and compressed air to be conveyed by the conveying conveyor. Or a vibrator can also be used.

Injection of the compressed air may be made by an air injection nozzle and a compressor.

At this time, the rice cooked in the separation step (S30) can be input by the manpower or by a mechanical device.

The separation step (S30) may be repeated two or more times in consideration of the separation of the rice grains.

The freezing step (S40) is the rice after the separation process is conveyed by agglomerate unit in a certain lump unit through a conveying conveyor, it is rapidly frozen in the freezer.

In this case, a refrigerator having a plurality of freezing rooms is used to increase the freezing efficiency, and may further include condensation removing means for removing condensation of the conveying conveyor.

The condensation removing means is to immerse the conveying conveyor in hot water, and then to dry the conveying conveyor.

The packaging step (S50) is a step of packaging the frozen rice frozen in the freezing process using a wrapping paper. Of course, the packaging process (S50) may be made by manpower, it is also possible to automatically packaging by placing a sorting machine according to the weight.

Although the present invention is used in various cereals, hereinafter, rice will be described as an example.

The frozen rice manufacturing system comprises a rice grain scattering apparatus 100 and a rapid freezing apparatus 200 of the frozen rice manufacturing apparatus, the rice grain scattering apparatus 100 of the frozen rice manufacturing apparatus is an embodiment of the present invention. Yes.

In addition, the packaging unit 500 for the next process or product packaging of the product frozen through the rapid freezer 200 of the frozen rice manufacturing apparatus may be further installed.

In addition, an automatic cooking apparatus (not shown) may be further installed before the rice scattering apparatus 100.

In addition, before the rice scattering device 100, the input unit 90 may be further installed to automatically feed the rice cooked rice into the rice scattering device 100.

The frozen rice manufacturing system moves in a state in which the conveying conveyor (101,201) arranged the rice 10 over the rice scattering device 100 and the rapid freezing device 200 of the frozen rice manufacturing device.

The rice scattering device 100 is as shown in Figures 3a and 3b.

The rice scattering device 100 comprises a conveying conveyor 101, a roll brush 110 and a compressed air injection unit.

In addition, the rice grain scattering apparatus 100 may further include an input unit 90 for injecting the rice 10. In addition, the input of the rice 10 can also be by manpower.

When the rice 10 collected in the rice scattering device 100 is supplied in a state arranged on the transfer conveyor 101, the rice 10 is primarily in the rice grain unit by the roll brush 110. Scattered.

Here, the conveying conveyor 101 is rotated by the drive roller 102 and the driven roller 103.

In addition, the conveying conveyor 101 is a conveying conveyor support (not shown) is installed between the drive roller 102 and the driven roller 103 may be supported by the conveying conveyor (101).

Of course, the transfer conveyor 101 may be supported by a plurality of frames (not shown).

In addition, the transfer conveyor 101 may be used a general mesh network conveyor belt.

Here, the roll brush 110 may be adjusted by the lifting cylinder 120 and the distance to the conveying conveyor 101.

The roll brush 110 is a combination of a roll and a plurality of brushes along the circumferential surface of the roll.

And the interval between the roll brush 110 and the conveying conveyor 101 is adjusted by the lifting cylinder 120 according to the type of grain.

The injection angle is preferably inclined in the reverse direction of the traveling direction of the transfer conveyor 101 to improve the separation efficiency.

In addition, the plurality of air injection nozzles 150 may be made to swing.

At this time, the swing direction of the plurality of air spray nozzles 150 is not limited, but it is advantageous for the scattering of the bob 10 to swing in a direction perpendicular to the traveling direction of the transfer conveyor 101.

Therefore, the compressed air can be injected even in a place where the plurality of air spray nozzles 150 are not installed, and the cost can be reduced by reducing the number of installation of the air spray nozzles 150.

Although the swing directions of the plurality of air injection nozzles 150 are not limited, the swing directions of the air injection nozzles 150 adjacent to each other are preferably operated opposite to each other.

Therefore, when the swing directions of the plurality of air spray nozzles 150 are the same in one direction, the bob 10 disposed in the conveying conveyor 101 is biased toward one side, so that scattering efficiency is reduced in units of rice grains. Can be prevented.

Compressed air is injected by the air spray nozzle 150 to scatter and cool the rice 10.

Therefore, while the rice 10 is scattered by compressed air, the rice 10 can be pre-cooled before being transferred to the freezing process, thereby reducing the freezing time in the freezing process and increasing the freezing efficiency.

In addition, the compressed air injection unit may further include a moisture supply means (not shown).

The moisture supply means is preferably connected to the air supply pipe (131, 132, 133).

Rapid freezing device 200 of the frozen rice manufacturing apparatus is as shown in Figures 4 to 7.

Referring to Figures 4 to 7, the refrigeration apparatus 200 of the frozen rice manufacturing apparatus, the freezer is installed on the conveying conveyor 201 is formed.

The transfer conveyor 201 continuously supplies the aggregated grains.

Hereinafter, the present invention will be described based on rice, which is a kind of grain.

The conveying conveyor 201 continuously feeds the combined rice 10 to the freezer as shown in FIG. 4, and transfers the frozen rice 10 from the freezer to the packaging unit 500 or another process. .

Then, the conveying conveyor 201 is rotated by the drive roller 202 and the driven roller 203.

In addition, the conveying conveyor 201 is a conveying conveyor support (204, 205) is provided between the drive roller 202 and the driven roller 203 is supported by the conveying conveyor (201).

There is no limitation on the operation of the refrigerator, and various methods such as general vapor compression or absorption may be applied.

In addition, the internal temperature of each of the plurality of freezing rooms is characterized in that it is sequentially lowered according to the progress direction of the grain.

In other words, a plurality of freezing rooms are installed in the traveling direction of the conveying conveyor 201, and the temperatures inside the plurality of freezing rooms are sequentially lowered along the moving direction of the grain, so that they are arranged in the conveying conveyor 201. The rice 10 is frozen while passing through a plurality of freezers.

Conventionally, since the internal temperature is frozen at -40 in one refrigerator, the temperature difference between the initial rice temperature and the freezer is large, and thus the refrigeration efficiency is not good because the irreversibility increases due to the second law of thermodynamics during heat transfer.

As described above, when the rice 10 is sequentially frozen while passing through a plurality of freezing rooms, heat transfer occurs in a state where the temperature difference between the rice and the freezing room is small and thus can be efficiently frozen.

Therefore, the refrigeration efficiency is increased, the energy consumption can be reduced, and the production cost can be reduced.

In addition, there is no limitation on the number of freezing rooms that the freezer has, and the temperature difference of each freezing room is not limited as long as the temperatures of the plurality of freezing rooms are sequentially lowered according to the progress direction of the grain.

However, as the number of freezing rooms of the freezer increases, the temperature difference with the rice 10 can be reduced, so that heat transfer can be efficiently performed. .

That is, the freezer may include a first freezing room 210, a second freezing room 220, and a third freezing room 230.

The plurality of freezing rooms are supplied with energy by a plurality of freezing units (213, 223, 232) and the internal temperature is controlled.

The control unit 240 may be connected to the refrigerating units 213, 223, and 232 to adjust temperatures in the plurality of freezing rooms.

At this time, the plurality of freezing rooms are attached to the temperature measuring sensors (212, 222, 231), respectively, when the control unit 240 controls the internal temperature of the plurality of freezing rooms by the temperature measuring sensors (212, 222, 231) The temperature of the controller is transmitted to the controller 240.

Therefore, the internal temperature of the plurality of freezing rooms is effectively maintained at the set internal temperature.

Here, the first freezing room 210 maintains the internal temperature set to the first temperature. In addition, the first temperature is preferably maintained at -15 degrees to -20 degrees.

Here, the second freezing room 220 is installed adjacent to the first freezing room 210 in the advancing direction of the grain to maintain the internal temperature set to the second temperature. The second temperature is preferably maintained at -25 degrees to -30 degrees.

Here, the third freezing room 230 is installed adjacent to the second freezing room 220 in the advancing direction of the grain to maintain the internal temperature set to the third temperature. The third temperature is preferably -35 degrees to -40 degrees.

Therefore, it is advantageous in view of the refrigeration efficiency, freezing time, space constraint that the refrigerator has three freezing rooms and maintains the above temperature as described above.
