A grain inlet 41 is formed at the starting end side 7a of the protruding portion 3. And the grain input hopper 42 slightly shifted to the outer peripheral side is arrange|positioned so that grain can be put in from the tangential direction of the outer peripheral edge 7g of the starting end side 7a of the thoroughfare (Fig. 1, 4(A) and 4(B)). This grain input hopper 42 is provided with an inclined chute 43 having a width of about 120 mm and a length of about 150 mm, and a water supply nozzle 44 at the lower end of the inclined chute 43 Is formed fixed. Thereby, when the grain is put into the grain inlet 41 from the inclined chute 43, it can be put in a state in which grains are aligned from the tangential direction of the outer peripheral edge 7g. In addition, since the water from the water supply nozzle 44 is carried out while the grains are falling from the lower end of the inclined chute 43 to the doping tube 7, the pressure of the water by the water is weakened due to the momentum of the flow of the grains. Can be prevented. Reference numeral 45 denotes a water supply port at the front end of the water supply nozzle 44, and this water supply port 45 is a wide opening (see Fig. 4(B)) over the width direction of the inclined chute 43 have. For example, when the dimension in the width direction of the inclined chute 43 is 120 mm, it is preferable that the dimension in the width direction of the water supply port 45 is approximately equal to 100 mm. Reference numeral 46 denotes a water supply pipe, and numeral 47 denotes a joint connecting the water supply pipe 46 and the water supply nozzle 44 to the water supply nozzle 44 through the water supply pipe 46 and the joint 47 by a pump not shown. Water can be supplied.

Next, the operation of the fine grain production apparatus of the above configuration will be described. The polished rice serving as a raw material supplied from the raw material supply chute 50 is supplied to the grain input hopper 42 by a rotary valve 51 which is a grain supply device 4. And, the fine grains reach the grain input hopper 42 from the passage 52, and in the grain input hopper 42, the state is aligned in the tangential direction of the outer peripheral edge 7g by the inclined chute 43 formed in the hopper. It is put into the Dojeongtong 7 at. At this time, water is added by the water supply nozzle 44 fixedly formed at the lower end of the inclined chute 43, and, for example, is added in an amount of 10 to 20% by weight with respect to the polished rice.

And, since the addition of water from the water supply nozzle 44 is carried out while the fine particles are falling from the lower end of the inclined chute 43 to the doping tube 7, the momentum of the flow of the fine particles causes the addition of water by water. The pressure is weakened, which can prevent splashing. In addition, since the water supply port 45 at the tip of the water supply nozzle 44 is a wide opening over the entire width in the width direction of the inclined chute 43 (refer to Fig. 4(B)), the inclined chute (43) It is possible to add water evenly to all fine particles flowing down without unevenness, which can contribute to quality improvement.

Next, the fine grains are conveyed to the grinding cylinder 7 side by the feeding angle screw 9 in the grinding cylinder start-end side 7a, and agitation and polishing are performed in the grinding cylinder 7 by a plurality of stirring blades 10. The polished rice is polished by the friction of the particles in the water while the strong powder generated by the polishing diffuses into the water. The degree of polishing at this time proceeds by 0.5 to 2.0% with respect to the fine particles, so that the aluron layer on the surface of the fine particles peels off and falls off. During such agitation/polishing, the outflow of the fine grains from the grinding cylinder 7 is regulated by the restricting member 12 pivoted on the grinding shaft 8. The dimension of the gap between the regulating member 12 and the conduction cylinder 7 at this time is preferably in the range of 3 to 15 mm, more preferably, in the range of 5 mm to 13 mm in which fine particles can flow out. Just set it.

Fig. 5 is an enlarged view when cut along the line A-A in Fig. 3. The regulating member 12 pivoted at the tip of the polishing shaft 8 has an outer diameter approaching the inner diameter of the polishing barrel 7 to narrow the gap, so that the outflow of the polished rice from the polishing barrel 7 is restricted. Fig. 5 shows an example of the dimensions of the regulating member 12 and the metropolitan barrel 7. The limiting member 12 is a disk shape, the outer diameter of the cross section is 140 mm, the inner diameter of the narrowest point of the roughly hexagonal doping tube 7 is 150 mm, and the inner diameter of the widest point of the doping tube 7 is 166 Mm. And, the gap through which fine particles can flow out is 13 mm at the maximum and 5 mm at the minimum. By forming in such a gap dimension, it is possible to supply the fine particles to the centrifugal dewatering unit 5 while restricting the outflow from the grinding cylinder 7.

In this way, as a method of supplying the fine particles to the next step of the fine particles (for example, the centrifugal dewatering unit 5) while controlling the outflow of fine particles from the thoroughfare 7, conventionally, Japanese Laid-Open Patent Publication No. Hei 5-68896 There was a method of pressing the resistance cover to the outlet described in paragraph 0006 of FIG. 1 or in FIG. 1. However, in the pressure regulating mechanism for pressing the resistance cover to such an outlet, it is necessary to connect to the next step through a receiving hopper serving as another component, and there is a problem that the gas becomes large.

On the contrary, if the restricting member 12 is pivotally pivoted at the tip end of the polishing shaft 8 as in the present embodiment, and the gap with the polishing barrel 7 is narrowed, the polishing barrel 7 is replaced with a dewatering container 18 It can be directly connected to ), which has the advantage of miniaturizing the aircraft. In addition, since water milling is carried out while controlling the outflow of polished rice from the mill 7 by the regulating member 12, residual deposits are not easily generated in the mill 7 It becomes possible to provide.

Continue to explain the action. Next, when the fine particles are supplied to the dewatering tank 18 of the centrifugal dewatering unit 5, in the centrifugal dewatering unit 5, the fine particles and water are vertically rotated by the rotation of the dewatering screw 20 (for example, 2000 rpm). It is conveyed in the direction, and at this time, while the fine particles and water are conveyed, by the action of the centrifugal force by the rotation of the dewatering vessel 18 (for example, 1700 rpm), the porous wall portion 17 of the dewatering vessel 18 In this case, it is separated into fine particles and water containing strong powder and aleuron. In addition, the separated water is discharged to the outside of the aircraft through the drain cover 21 and the drain container 22, and drainage treatment is performed in a drainage treatment facility (not shown), while the dewatered fine particles are dewatered. It is scraped off from the dewatering tank 18 from the lower extraction blade 30 and transferred to the tempering/drying part 6 through the flow channel 31.

In the tempering and drying unit 6, when fine particles are supplied to the first screen 32 in the vibration machine frame 35, the fine particles are supplied to the first screen 32 and the second screen 33 by the vibration motor 37. And the third screen 34 is transferred while being sequentially driven. In addition, the hot air from the hot air supply fan 38 is supplied under the first screen 32, the second screen 33 and the third screen 34, and by hitting the hot air while moving the fine particles, · Drying is carried out. And, from the genuine duct 40, the finished non-semi-finished rice with a moisture content of around 15%, for example, is discharged.

If the fineness is manufactured as described above, in this embodiment, the polishing shaft 8 supported so that the polishing shaft 3 can freely rotate in the polishing barrel 7 and the shaft pivot on the polishing shaft 8 The agitating electron 11 which fixed one pine angle screw 9 and a plurality of stirring blades 10 and axially pivoted to the polishing shaft 8 and pivoted to the tip end of the polishing shaft 8, Since it is constituted with a regulating member 12 that narrows the gap with the inner diameter of the guide tube 7 to regulate the outflow of fine particles from the guide tube 7, the guide tube 7 is formed by the regulating member 12. Underwater milling is carried out while regulating the outflow of fine particles from. As a result, it becomes possible to provide a fine grain manufacturing apparatus excellent in a sanitary surface, since the inside of the pottery barrel 7 is always in a full state, and residual deposits do not easily occur. Further, since the provincial section 3 and the centrifugal dewatering section 5 can be connected directly without passing through the accommodation hopper, the gas can be downsized.

In addition, a grain input hopper 42 for feeding fine grains into the grain inlet 41 opened to the grain inlet 41 is disposed on the starting end side 7a of the grain in the grain in the grain in the grain feeding hopper ( 42) is provided with an inclined chute 43, and at the lower end of the inclined chute 43, a wide water supply port 45 having a width substantially equal to the widthwise dimension of the inclined chute 43 is opened. Therefore, since the water from the water supply nozzle 44 is carried out while the fine particles fall from the lower end of the inclined chute 43 to the doping tube 7, the pressure of water at the time of water is weakened by the momentum of the flow of the fine particles. , It has the merit of preventing splash.

In addition, between the centrifugal dewatering unit 5 and the tempering/drying unit 6, the longitudinal section is connected by a flow passage 31 such as a gentle arc, and after dehydration in addition to the extracting action of the extracting blade 30 It can be carried into the temper/dry part 6 while spreading the fine particles.

That is, as shown in FIG. 8, the extraction blade 30 is rotated by the rotation R of the dehydration shaft 19, and fine particles are scraped from the dewatering container 18 from the lower end of the centrifugal dewatering unit 5, As shown by arrow (A), it collides with the bent part of the arc-shaped flow channel 31. Thereby, the fine particles are scattered and diffused in all directions within the flow channel 31. As shown in Figs. 9 and 6, the flow passage 31 is formed in a shape that extends downward and spreads the inside of the flow passage 31 as shown by the broken line arrow A in FIG. 9 It falls. The lower end of the flow passage 31 is connected to the drying part supply chute 68, and the fine grains are supplied to the starting end side of the temper/dry part 6 as it is, as shown by the broken-line arrow B.

The tempering/drying unit 6 is a vibration machine frame formed by spreading first, second and third screens 32, 33, 34 sequentially from the supply side toward the discharge side for hitting the hot air while rolling the fine particles ( 35), an elastic member 36 for supporting the vibrating machine frame 35 so as to vibrate against the machine frame 2, a vibrating motor 37 for finely vibrating the entire vibrating machine frame 35, Hot air supply fans with built-in heaters (38a, 38b), exhaust duct (39) for discharging the wind that has passed through the screens (32, 33, 34) to the outside of the aircraft, and passes through the screens (32, 33, 34) Thus, it is composed of a genuine product discharge duct 40 for discharging the fine particles, which have been subjected to conditioning and drying, to the outside of the aircraft.

The first, second, and third screens 32, 33, 34 may employ a mesh net, a woven net, a punched metal, or the like having a grid width that does not pass through fine particles but allows dry air to pass through. In addition, the material can be appropriately adopted, such as iron, stainless steel, brass, and aluminum.

The first, second and third screens 32, 33, 34 have a step near the boundary (see Figs. 7, 8 and 10), and a step 63 is formed at each boundary. do. That is, a first step portion 63a is formed at the connection portion between the first screen 32 and the second screen 33, and a second step portion is formed at the connection portion between the second screen 33 and the third screen 34. 63b) is formed. By the steps 63a and 63b, when the fine particles ride from the first screen 32 to the second screen 33 and when the fine particles ride from the second screen 33 to the third screen, in each Since the fine grains are rolled, dry air is applied to not only one side of the fine grains, but also both surfaces of the fine grains to be dried, so that there is no fear of uneven drying.

10 is a cross-sectional view showing the internal structure of the tempering/drying unit 6. In this temper/dry section 6, a partition wall 64 is formed in the longitudinal direction of the lumen of the vibration machine frame 35. Two wind tunnels of the first wind tunnel 65a and the second wind tunnel 65b are formed by this partition wall 64. These two first wind tunnels 65a and second wind tunnels 65b have a structure capable of supplying dry air under different drying conditions (by varying temperature, air volume, etc.). In addition, the first screen 32 and the second screen 33 are positioned above the first wind tunnel 65a, while the third screen 34 is positioned above the second wind tunnel 65b. Each of the dampers 66a, 66b, and 66c for adjusting the air volume are formed in the lower portion of the first wind tunnel 65a, and the dampers 66d, 66e, and 66f for adjusting the air volume in the same manner are formed in the lower portion of the second wind tunnel. .

The hot air supply fan 38a is connected to the first wind tunnel 65a, while the hot air supply fan 38b is connected to the second wind tunnel 65b through a communication pipe 67. Thereby, from the hot air supply fan 38a, dry air having a relatively high temperature and a large air volume for primary drying, for example, a temperature of 60 to 80°C and an air volume of 80 m 3 /min, passes through the first wind tunnel 65a. It is sprinkled on the fine particles on the first screen 32 and the second screen 33 through the air, and exhaust air is discharged to the outside of the aircraft through the exhaust air duct 39. On the other hand, in the hot air supply fan 38b, for secondary drying, a relatively low temperature and a small air volume, for example, a drying air having a temperature of 30 to 50°C and an air volume of 60 m 3 /min, is transmitted through the second wind tunnel 65b. It is sprinkled on the fine particles on the third screen 34, and the exhaust air is discharged to the outside of the aircraft through the exhaust air duct 39. In addition, the time for the fine particles to pass through the first screen 32 and the second screen 33 on the first wind tunnel 65a is about 15 seconds, and similarly, the third screen on the second wind tunnel 65b ( 34) The time for fine particles to pass is also about 15 seconds.

Next, the operation of the fine grain production apparatus of the above configuration will be described. The polished rice serving as a raw material supplied from the raw material supply chute 70 is supplied to the grain input hopper 42 by a rotary valve 71 which is a grain supply device 4. Then, the fine grains reach the grain input hopper 42 from the passage 72, and water is added by a water supply nozzle (not shown) fixedly formed in the grain input hopper 42, for example, polished rice It is added in an amount of 10 to 20% by weight.

Next, the fine grains are conveyed to the grinding cylinder 7 side by the feeding angle screw 9 in the grinding cylinder start-end side 7a, and agitation and polishing are performed in the grinding cylinder 7 by a plurality of stirring blades 10. The polished rice is polished by the friction of the mouth in the water while the steel powder generated by the polishing is diffused into the water. The degree of polishing at this time proceeds by 0.5 to 2.0% with respect to the fine particles, so that the aluron layer on the surface of the fine particles peels off and falls off. During such agitation and polishing, the flow of fine grains from the grinding cylinder 7 is regulated by the restricting member 12 pivoted at the tip of the grinding shaft 8. The dimension of the gap between the regulating member 12 and the conduction cylinder 7 at this time is preferably in the range of 3 to 15 mm, more preferably, in the range of 5 mm to 13 mm in which fine particles can flow out. Just set it.

By forming the regulation member 12 in the range of this gap dimension, it is possible to supply fine particles to the centrifugal dewatering unit 5 while restricting the outflow of the fine particles from the grinding cylinder 7.

In this way, as a method of supplying the fine particles to the next step (for example, the centrifugal dewatering unit 5) while restricting the outflow of the fine particles from the mill 7, conventionally, paragraph 0006 of Japanese Laid-Open Patent Publication No. Hei 5-68896 Alternatively, there was a method of pressing a resistance cover to the outlet port shown in FIG. 6. However, in the pressure regulating mechanism for pressing the resistance cover to such an outlet, it is necessary to connect to the next step through a receiving hopper serving as another component, and there is a problem that the gas becomes large.

On the contrary, if the restricting member 12 is pivotally pivoted at the tip end of the polishing shaft 8 as in the present embodiment, and the gap with the polishing barrel 7 is narrowed, the polishing barrel 7 is replaced with a dewatering container 18 ) Can be directly connected to, which has the advantage of miniaturizing the aircraft. In addition, since water milling is carried out while controlling the outflow of polished rice from the mill 7 by the regulating member 12, residual deposits are not easily generated in the mill 7 It becomes possible to provide.

Next, when the fine particles are supplied to the dewatering tank 18 of the centrifugal dewatering unit 5, the fine particles and water in the centrifugal dewatering unit 5 are reduced by rotation of the dewatering screw 20 (for example, 2000 rpm). It is conveyed in the direction, and at this time, while the fine particles and water are conveyed, by the action of the centrifugal force by the rotation of the dewatering vessel 18 (for example, 1700 rpm), the porous wall portion 17 of the dewatering vessel 18 In this case, it is separated into fine particles and water containing strong powder and aleuron. In addition, the separated water is discharged to the outside of the aircraft through the drain cover 21 and the drain container 22, and drainage treatment is performed in a drainage treatment facility (not shown), while the dewatered fine particles are dewatered. It is scraped off from the dewatering tank 18 from the lower extraction blade 30 and transferred to the tempering/drying part 6 through the flow channel 31.

8 and 9, the extraction blade 30 is rotated by the rotation of the dehydration shaft 19 (arrow (R)), from which fine particles are scraped from the dewatering cylinder 18, and then, fine particles. Collides with the arc portion of the flow channel 31 (arrows (A) in Figs. 8 and 9), and scatters in all directions from the inside of the flow channel 31 and diffuses. Then, it falls while spreading the inside of the flow channel 31, and it falls downward in the drying part supply chute 68 (arrows (B) in Figs. 8 and 9), and the fine grains remain as it is, the temper/dry unit 6 It is supplied to the beginning of the.

In the temper/dry section 6, by vibrating motor 37 attached to the vibrating machine frame 35, for example, the vibrating machine frame 35 has an amplitude of 3 to 4 mm, and the number of rotations of the motor is 1000 to the frequency. It is finely vibrated under conditions of 1200 rpm (50 HZ/60 HZ), and the first screen 32, the second screen 33 and the third screen 34 are sequentially transferred from the supply side to the discharge side.

When the fine particles are transferred onto the first screen 32 and the second screen 33, a drying air having a relatively high temperature and a large air volume for primary drying is supplied from the hot air supply fan 38a, so that the centrifugal dewatering unit 5 ), it is possible to dry/remove a large amount of surface adhered water that has not been removed.

Subsequently, when the fine particles are transferred onto the third screen 34, dry air having a relatively low temperature and a small air volume is supplied from the hot air supply fan 38b for secondary drying, so it is slightly adhered to the surface of the fine particles after the first drying. Since the surface adhered water (just before the adhering water disappears) is dried and removed, it is possible to suppress an increase in the grain temperature of the fine particles and to suppress the occurrence of cracks on the surface of the fine particles due to overdrying.

Then, the fine particles that have passed through the third screen 34 are discharged from the genuine duct 40 to the outside of the aircraft, and, for example, the finished non-semi-fine particles of about 15% moisture are discharged.

Although the non-semi-fine is manufactured as described above, in the present embodiment, the centrifugal dewatering unit 5 and the tempering/drying unit 6 are communicated through a flow passage 31 having an arc shape with a gentle longitudinal section. In addition, at the lower end of the centrifugal dewatering unit 5, a extraction blade 30 for carrying the distilled fine particles after the centrifugal dehydration against the inner surface of the arc-shaped flow channel and carrying it into the temper/dry unit 6 ) Is pivoted, it is possible to scrape the fine particles from the centrifugal dewatering unit 5 and collide with the arc-shaped bent part of the inner surface of the flow container 31, whereby the fine particles It is scattered and diffused to be supplied to the temper/dry unit 6. Thereby, there is no possibility that fine grains become coagulated and carried into the tempering/drying unit, and drying without unevenness is performed, and fine grains of good quality can be produced.

In addition, the tempering/drying unit 6 includes a vibrating machine frame 35 formed by spreading and forming screens 32, 33, 34 for hitting hot air while moving fine particles, and the vibrating machine frame 35 (2) an elastic member 36 supporting vibrably against (2) a vibration motor 37 for finely vibrating the entire vibration machine frame 35, hot air supply fans 38a, 38b with built-in heaters, Since it is composed of a genuine discharge duct 40 that passes through the screens 32, 33, 34 and discharges the fine particles that have been tempered and dried to the outside of the aircraft, the fine particles are dried while rolling on the screen by the vibrating machine frame 35. Since the air is supplied, dry air is applied to not only one side of the fine particles, but also both surfaces of the fine particles to be dried, so that there is no fear of uneven drying.

In addition, the screens 32, 33, and 34 formed by spreading on the vibration machine frame 35 are formed by sequentially spreading a plurality of screens from the supply side to the discharge side of the vibration machine frame 35, and the plurality of screens When the step portions 63a and 63b are formed near the boundary of (32, 33, 34), effective transmission of the fine particles is performed when the fine particles ride from one screen 32 to the other screen 33, Drying wind touches not only one side of the fine particles but also both surfaces of the fine particles to be dried, and there is less possibility of occurrence of dry unevenness.

Further, in the lumen of the vibration machine frame 35, a partition wall 64 is formed in the longitudinal direction, and the two wind tunnels of the first wind tunnel 65a and the second wind tunnel 65b are formed by the partition wall 64. Is formed, and the first screen 32 and the second screen 33 are positioned on the top of one of the first wind tunnels 65a, and the third screen is on the top of the second wind tunnel 65b on the other side Position (34).

Accordingly, if the structure capable of supplying dry air under different drying conditions (by varying temperature, air volume, etc.) between the two first and second wind tunnels 65a and 65b, When there is a lot of adhesion moisture, the drying speed is accelerated, and when the adhesion moisture of fine particles at the end of drying is low, the drying speed is slowed to suppress an increase in the grain temperature of the fine particles, and the occurrence of cracks on the surface of the fine particles due to overdrying can be suppressed. .

In addition, when dampers 66a to 66f for air volume adjustment are formed in the lower portion of the first wind tunnel 65a and the lower portion of the second wind tunnel 65b, respectively, the first wind tunnel 65a and the second wind tunnel 65b ), you can adjust the air volume of the dry wind.
