Description

Humidifying device of uncleaned rice for improving the pounding efficiency and rice quality}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a brown rice (processed product from which rice husks have been removed by passing brown rice and rice paddy through rice mill) for improving the yield and quality of rice. It is installed to make uniform water and water penetration with brown rice falling freely with uniform width and thickness. Also, moisture meter is installed in the brown rice supply path to automatically measure the moisture of brown rice and then to make water to the proper amount. Efficient and accurate brown rice singer with uniform temperature throughout brown rice by keeping constant temperature of water tank to supply spray water with hydro-nozzle in advance By making (crude), the milling yield and quality are greatly improved.

In general, the milling moisture content of rice varies slightly depending on varieties, regions, processing facilities, distribution patterns, etc., but it is about 14-16% (wb) in Korea. If the water content is higher than this, the rice bran generated in the rice milling process is attached to the rice milling network, causing the failure of the machine.In the case of the water content being low, it is not only easy to generate debris due to the impact that passes through the rice mill and rice milling machine but also the milling yield. This lowers and the required driving force of the rice polisher is increased.

As such, the water content of the mill is very closely related to the mill yield, the required power, and the quality of the rice. Therefore, when the water content of rice is low, the hydrolysis process must be preceded.

Brown rice soak (현 米加 水) refers to adding moisture to long-term storage and overdried rice to equalize the distribution of moisture inside and soften hard internal tissues. This prevents the occurrence of debris due to the impact and friction generated during the rice milling process to improve the milling yield and at the same time significantly reduce the load of the rice mill.

However, attention must be paid to the occurrence of moisture due to re-hygroscopicity of moisture while adding moisture for brown rice singers. The amount of water required for hydrolysis depends on the initial moisture content and varieties of brown rice, so adequate water content should be determined through sufficient experiments. If water is unconditionally added to brown rice without this process, the occurrence of copper activity due to moisture re-absorption may increase, and thus may cause a problem of lowering the milling yield.

The brown rice watering device currently installed and used in the milling factory supplies water by installing a nozzle on the screw conveyor for brown rice supply, and then penetrates water from the brown rice tank, and a simple type that supplies water by installing a nozzle in the rice mill input unit. It is known to use a lot of watering devices, and in some cases it is known to apply a humidifier using ultrasonic waves.

On the other hand, if you look at the brown rice singer method can be largely divided into a moisture penetration method and a humidification method, the water penetration method is subdivided into a full penetration method by a batch type (Batch type) and a surface penetration method by a continuous type (Continuous type) The humidification method can be subdivided into batch, continuous and ultrasonic humidification methods.

The complete osmosis method (batch type) is a method of adjusting the moisture content of brown rice and white rice by completely penetrating the water to the inside of brown rice, it takes a lot of time (more than 20 hours) to penetrate the moisture, the moisture measuring device for water content control In addition, there is a risk of deterioration due to the infiltration of moisture due to internal penetration of moisture and neglect of summer management, and there is a problem such as difficult or impossible to sing in winter when the temperature drops sharply because the temperature is not taken into account when water is infiltrated.

In addition, the surface penetration method (continuous type) adds moisture to the surface of brown rice immediately after adding moisture to the surface of brown rice, so that the required time is short, so the process is made continuously, and no moisture measuring device is needed. There is no problem, but proper temperature control is needed to smooth moisture penetration.

In addition, the batch type humidification method is a method of spraying and spraying water on the flat plate after developing the brown rice on the plate, the continuous humidification method is a method of spraying and spraying water inside the screw conveyor, the ultrasonic humidification method is an ultrasonic humidifier 1 is a block diagram of a batch type watering device, and FIG. 2 is a block diagram of a continuous type watering device. The "rice grain humidifier" that improves the taste of rice by humidifying to maintain water content of about 15% in rice grains to prevent cracking has been disclosed in Korean Patent Publication No. 1990-0008241, but it is a device that hydrolyzes rice instead of brown rice. It is one of the representative examples of the batch type water purifier shown in Fig. 1, i.e., when the polished rice is put in the water tank and the water content is frequently sampled while reaching the target moisture value. The composition is complicated by the constant water content of the outer and central parts while continuing to circulate through the screw, and an appropriate amount of water is added to the brown rice even when the brown rice is polished with white rice. That is, when the appropriate amount of moisture content is maintained, the steel layer on the surface of the brown rice is softened to be cut when applied with white rice, and also the friction coefficient is reduced during the milling to reduce the loss even when cutting, thereby improving the milling yield. The device) is a device that is hydrolyzed to white rice rather than brown rice, and its structure and effect are different from the present invention described later.

Therefore, an object of the present invention is to provide a spreading device and a watering device for freely dropping brown rice in a uniform width and thickness in a lower portion of the hopper so that uniform watering and water penetration can be achieved by falling brown rice. .

In addition, it is intended to prevent troublesome and inaccurate control according to the occasional measurement by measuring the moisture of brown rice by incorporating (high frequency) moisture meter in the brown rice feeding device.

In addition, by installing a water temperature sensor and a heating heater inside the tank for supplying the sprayed water to maintain a constant temperature before and after 20 ℃ to achieve a uniform heating effect regardless of the season or ambient temperature. .

In order to achieve the above object, a brown rice developing device is installed in the lower part of the hopper so that freely falling brown rice falls freely in a uniform width and thickness (thin layer) while allowing uniform water and water penetration by a plurality of nozzles installed. In addition, the (high frequency) moisture meter is built in the brown rice supply device to measure the moisture of brown rice supplied and automatically hydrolyze it at the set water content (singular water content) to prevent the hassle and inaccurate control that requires frequent measurement of brown rice moisture. This prevents efficient and accurate brown rice singer (micro-grained crude) to significantly improve the milling yield and quality.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The present invention, the brown rice brewing machine 2 installed and operated in the pre-processing step of the polished rice, has a developing device 6 freely dropping to a uniform width and thickness so as to achieve uniform water flow of the brown rice discharged from the hopper 4; Measure the moisture (water content) of the brown rice in the hopper 4, and then, in cooperation with the controller 10, the brown rice singer 8 for uniformly watering the brown rice falling to a uniform width and thickness. The water temperature of the (high frequency) moisture meter 12 and the water tank 14 for supplying the sprayed water is fixed at a temperature before and after 20 ° C. (17 ° C. to 23 ° C.) so as to automatically hydrolyze by the set amount of hydrolysis (single water content). It consists of a constant temperature device that keeps the oil and the upper and lower level detectors 16 and 18 that adjust the brown rice supplied to the hopper 4 to maintain a constant amount. By doing so, the yield of white rice can be increased and the quality of white rice can be improved.

On the other hand, the present invention brown rice singer (2) is a transfer device of the same type of brown rice chute chute or conveying conveyor peeled by the brown rice purifier not shown in the upper portion of the base 22 as shown in Figs. By this, it is supplied to the hopper 4 via the inlet 24, and the developing apparatus 6 which has a rectangular cross section is provided in the discharge port part of the hopper 4. As shown in FIG.

The developing device 6 is formed in a rectangular shape having a narrow width and a relatively long length so that the brown rice 20 discharged from the hopper 4 can be discharged with a narrow width as shown in FIGS. 3 to 7. To freely fall into a uniform width and thickness, and the manual gate 26 is installed between the hopper (4) and the deployment device (6) to control the discharge and discharge width of brown rice (20) In the lower part of the deployment apparatus 6, an automatic gate 30 opened and closed by the air cylinder 28 is provided.

Another support member 34 is fixed to an upper portion of the support member 32 fixed to the outer side of the deployment device 6, and the tannery bolt 36 and the nut 38 are attached to the support member 34. Screwed horizontally, the rear end of the manual gate 26 to the front end of the tannery bolt 36 is screwed with a nut 40 so that the opening degree of the manual gate 26 can be manually adjusted.

On the other hand, the brown rice singer (8), which may vary depending on the capacity of the brown rice singer (8), but is connected to the lower part of the developing device (6), is somewhat spaced apart from FIGS. 5 and 7 and the freely falling brown rice (20). 4 or more of the plurality of singular nozzles 42 and 44 are installed on the side walls 46 and 48 at the predetermined positions, respectively, and the spray holes are installed to face the center of the brown rice singer 8. The water is sprayed at an appropriate pressure depending on the moisture to ensure an even and even valence on the brown rice surface.

In addition, the mantissa nozzles 42 and 44 maintain an appropriate separation distance from the falling brown rice 20 so that the mantissa area can be extended to effectively form a mantissa.

The discharge port 52 is formed in the lower portion of the brown rice singer (8) connected to the discharge chute 50, the cross-sectional area of the discharge port 52 is formed larger than the discharge cross-sectional area of the developing device 6, the brown rice Ensure a good discharge of the gas.

In addition, the plurality of hydrostatic nozzles (42) (44) and the connection hose 58 and the constant pressure device (54) and (56) for ejecting the sprayed water only when a constant water pressure, for example 4 kg / cm ² before and after the water pressure is maintained (60) and the pump 62 of the pump motor 64 under the control of the distributor 62 and the controller 10 and the water tank 14 for receiving and storing the water required for the water from the water supply 66, in order, The pump of the pump motor 64 is to feed water at a pressure of 5 kg / cm ² or more than the pressure of the constant pressure device (54) (56).

Therefore, when the lower limit level detector 18 is operated due to the lack of brown rice supplied to the hopper 4, the automatic gate 30 is closed by the air cylinder 28, and the operation of the pump motor 64 is also stopped. By the action of 54, 56, the water supply and the water are also interrupted, so that the injection water does not flow down to the chute 50.

When starting the watering operation in the above, if the automatic opening of the gate 30 and the brown rice sour device at the same time it takes a while to supply the water to the hoses 58, 60, the pump motor 64 is operated first Subsequently, the controller 10 may be set to open the automatic gate 30 with the air cylinder 28.

In order to solve the above problems, a check valve 72 may be installed between the pump and the distributor 62 of the pump motor 64 as shown in FIG. 7 so that water is always filled in the hoses 58 and 60. In this case, the hose 58, 60 and the check valve 72 and the portion where water is in contact with the heat insulating material is preferable to prevent freezing and freezing in winter.

On the other hand, the water tank 14 is connected to the water supply pipe 68 is connected to the water supply pipe 66, such as tap water or groundwater and the water supply pipe 68 is connected to the pump of the pump motor 64, In order to prevent the overflow or oversupply of water supplied to the outlet means by installing a non-illustrated subsidiary valve (blow plunger) and the like.

In addition, an electric heat heater 74 connected to the controller 10 and a water temperature sensor 76 for detecting the water temperature in the water tank 14 are installed inside the water tank 14 so that the heating temperature and the sensing water temperature of the controller 10 By the comparison control circuit, the constant temperature before and after 20 ° C is always maintained to prevent freezing of water for water, especially in winter.

The room temperature water maintained at the temperature before and after the temperature of 20 ℃ by the constant temperature device is not only better to make the water but also pressurized spray (pressing spray) in a mist state as if humidified with a humidifier so that the water of the brown rice 20 is evenly made. do.

8 to 12 show a pair of conductive electrode plates 84 and 86 for measuring moisture in the brown rice 20 accommodated in the hopper 14 and the electrode plates 84 and 86 as the hopper 14. Insulation fixing member 88, 90 for fixing to the drawing.

The electrode plates 84 and 86, which are moisture probes, are connected to the moisture measuring circuit with a signal line 92 so that a moisture measuring signal is input and fixed to the inner wall of the hopper 4 by a piece 96. The insertion grooves 94 are formed in the upper side and the upper side of the 88 and the 90 so that the electrode plates 84 and 86 are vertically inserted to prevent the drop movement of the brown rice 20.

The moisture measuring device 12 measures the moisture by using the patent application No. 1998-21390, "Non-destructive moisture content measuring method and apparatus using a phase difference" which the applicant has filed before the present invention, thereby greatly improving the performance of the product. Can be improved.

FIG. 15 is a side view of the level sensors 16 and 18 respectively provided on the upper and lower portions of the hopper 4 of the present invention, and shows the height or level (amount) of the brown rice 20 supplied to the hopper 4. When the upper limit level sensor 16 operates to stop the supply of brown rice to the hopper 4, and when the lower limit level detector 18 operates, the automatic gate 30 installed below the hopper 4 is closed. At the same time, the brown rice supply is started so that the brown rice is always supplied between the upper and lower level sensors 16 and 18 of the hopper 4.

The level sensors 16 and 18 are installed to protrude the rotary shaft rod 100 of the motor 98 into the hopper 4 and then rotate the flat plate 102 at the end of the rotary shaft rod 100. As a result, when the supply height of the brown rice 20 rises up to the rotating plate 102 of the upper limit level sensor 16, the rotation load of the motor 98 of the upper limit level sensor 16 increases according to the contact resistance of the brown rice. Detects that the brown rice 20 has risen above the height of the flat plate 102, and stops supply of the brown rice 20 to the hopper 4, on the contrary, the brown rice 20 is discharged as it is discharged, the flat plate of the lower limit level detector 18 If the height is less than 102, the contact resistance of the brown rice is almost absent or the rotation load of the motor 98 of the lower limit level sensor 18 is reduced, so that the controller 10 determines that the hopper 4 has little brown rice and the hopper 4 ) Close the automatic gate (30) and at the same time stop the operation of the pump motor (64) Stop unsinged work.

16 is a circuit block of the controller 10 of the present invention. The water temperature sensor 76 and the hopper 4 which sense the water temperature of the water tank 14 at the input of the control unit 80 composed of a CPU or a MICOM. Moisture meter 12 for measuring the moisture of the brown rice 20 located in the inside, upper and lower level sensors 16, 18 for sensing the supply amount of the brown rice 20 supplied to the hopper 4, and a water tank ( A setting unit 78 for connecting or setting the water temperature, the water content of the water, the operating time, the operation ON / OFF, and the like of 14) is connected.

In addition, the output of the control unit 80, in cooperation with the water temperature sensor 76, the heat transfer heater 74 for adjusting the temperature of the water in the water tank 14 before and after 20 ℃, and the automatic gate 30 is opened during the water When the brown rice 20 falls to the brown rice singer 8 and the lower limit level detector 18 operates, it is determined that the brown rice 20 is insufficient and the air cylinder 28 that closes the automatic gate 28 and the mantle nozzle ( Pump motors connected to the hoses 58 and 60 and the water tank 14 connected to the hydrostatic devices 54 and 56 of the 42 and 44, respectively, to supply sprayed water to the water-soluble nozzles 42 and 44 ( 64 and an alarm unit 82 that emits an alarm sound and an alarm light when an abnormality occurs and when the gates 26 and 30 are opened and closed or when the machine is operating.

In addition, the water sprayed by the water-soluble nozzles 42 and 44 is preferably to be pressurized with water sprayed in a state of atomization, so as not to interfere with the falling motion of the brown rice 20, the moisture meter 12 The moisture content of the brown rice 20 sensed by the controller 10 is inputted to the controller 10, and the reference function rate set through the setting unit 78 and the input moisture content inputted through the moisture meter 12 are compared at the controller 10. The controller 10 adjusts the pumping degree of the pump by determining the amount of water according to the comparison value.

According to the present invention configured as described above, excessive hygroscopicity due to excessive hydrolysis may increase copper extremity due to rapid movement of moisture. It must be induced.

Therefore, uniform water is the most important factor in brown rice preparation. As water is supplied in the form of fine spray particles on the surface of brown rice, water is uniformly supplied to the surface of brown rice 20, so that an appropriate amount of water is provided in accordance with the optimal moisture absorption data. do.

In addition, the electrode plates 84 and 86 positioned at the bottom of the hopper 4 always contain a certain amount of brown rice 20 so that density and weight are corrected, and the moisture meter 12 located at the bottom of the hopper 4 is provided. ) Measures the moisture of the brown rice 20 on-line (on-line) and inputs it to the controller 80, so that the controller 10 uses the result in the brown rice singer and adds to the brown rice 20 having high moisture. If moisture is supplied, the quality of the product may be impaired, so more than 16% of brown rice need not be hydrolyzed as much as possible.

However, if the amount of brown rice of less than 16% is adjusted based on the experimental data to adjust the amount of hydrolysis, it is possible to minimize the quality impact of the product and improve the yield.

Looking at the advantages of moisture measurement, it is possible to reduce the appropriate amount of brown rice singer, yield and power, and accurate measurement of the water required for brown rice singer is one way to maximize the performance and quality of the product.

Automating work through moisture determination eliminates the need for the operator to adjust the amount of water each time the brown rice changes, and maintains optimal working conditions at all times.

On the other hand, in the conventional heating method (加 현 方式), when the brown rice is moved to the screw conveyor after watering, the heat transfer heater is installed on the outer wall of the screw conveyor to increase the surface temperature of the brown rice to increase the hygroscopic effect, but evenly on the brown rice In the present invention, there is a problem that does not warm, but in the present invention, by raising the water temperature of the water tank 14 to a constant temperature before and after the water is heated to 20 ° C by heating the water and the nonuniform heating of the grain by the heating on the conventional screw conveyor surface problem Will solve the problem.

That is, in the present invention, because the constant temperature device is heated to room temperature maintained at a temperature of 20 ° C before and after, the brown rice singer is better made, and the brown rice (pressurized) is sprayed in a mist state as if humidified with a humidifier. 20 is evenly formed and constant temperature is maintained by the heat transfer heater 74 and the water temperature sensor 76 installed in the water tank 14, so that the quality of the brown rice 20 is not affected, and the brown rice 20 is applied to the water. Since the temperature of the sprayed water is raised in advance, it is possible to achieve a uniform heating effect throughout the brown rice.

On the other hand, the discharge amount of brown rice 20 can be adjusted to the extent of opening and closing of the manual gate 26 installed below the hopper 4, and the brown rice 20 in the hopper 4 is uniform by the developing device 6. Free fall in width and thickness.

The brown rice 20 supplied to the hopper 4 in the above is developed in a thin layer for uniform watering in the developing device 6 while freely falling past the gates 26 and 30. The brown rice developed in a thin layer is supplied to the brown rice singer 8 by its own weight, and the surface of the brown rice 20 is hydrolyzed by the water sprayed from the hydrolysis nozzles 42 and 44 installed therein. It moves to the next process by the chute 50 and the conveyer which are installed in the lower (back) end of the water supply apparatus 8.

On the other hand, the upper and lower parts of the hopper (4) is provided with level sensors (16, 18) is limited to the operation of the automatic gate 30 and the water injection pump morph (64) discharged brown rice when the brown rice supply is insufficient Since excessive water supply is stopped, micro damage is prevented due to excessive water supply, so it is always possible to automatically supply an optimum amount of water.

As described above, the present invention has the effect of achieving uniform water and moisture permeation by installing a brown rice developing device and a watering device in the brown rice discharge path to induce the brown rice in the hopper to fall freely with a uniform width and thickness.

In addition, the moisture meter is installed in the hopper to automatically measure the moisture of brown rice to be hydrolyzed in the appropriate amount has the effect of preventing the hassle and inaccurate control to measure the moisture of brown rice from time to time in advance.

In addition, the temperature of the tank supplying the sprayed water is maintained at a constant temperature, so that an efficient and accurate brown rice singer (crude) can be achieved at a uniform temperature throughout the brown rice. Freezing is prevented.

In addition, by applying brown water suitable to long-term storage and over-dried brown rice by brown rice singer (현 米加 水), the internal moisture distribution is uniformed and soft internal tissue is softened, so the impact and friction generated in the rice milling process It is possible to prevent the occurrence of debris by the improved milling yield and at the same time can significantly reduce the load of the rice mill.
