Description

Cleaning-free manufacturing equipment

The present invention relates to a non-cleaning rice production device capable of producing non-cleaning rice.

In a conventional scrubber-free manufacturing device, as disclosed in Patent Document 1, a drain is formed between the primary scrubber portion and the secondary scrubber portion and between the secondary scrubber portion and the tertiary scrubber portion, There were three seminars that could be held.

Patent Document 2 discloses an apparatus for producing unwashed grains that can produce unwashed rice by passing it through a centrifugal dehydration unit after washing.

However, in the case of the non-cleaning rice manufacturing device described in Patent Document 1, the time for the fine particles to pass over each drain is short, so it is difficult to sufficiently drain the scrubbing water mixed with the fine grains and rice bran from each drain. For this reason, even if fresh rice water was supplied during the rice processing process for each tea, rice water mixed with rice bran always remained. In addition, in the multiple washing process as described above, the fine particles are washed by rubbing each other, so the rice bran acts as an abrasive and causes small scratches on the surface of the fine particles during the semi-stirring. As a result, there was concern about the quality of the rice, which caused underwater cracking (underwater cracking) during cooking and caused internal starch to leak out, resulting in soft rice.

In the apparatus for producing unwashed grains described in Patent Document 2, unwashed rice is manufactured by forming a polishing part (semi-part) that mixes and stirs grains (rice) with water and mills them in water, and a centrifugal dewatering part in this post-process. Since the process was performed once, the cleaning action was weak. In the semi-cooking device disclosed in Patent Document 3, the fine particles come into contact with and collide with the element when flowing and inverting the inside of the pipe, so there is a risk that the fine particles will be damaged, leaving unrest in the quality of the rice.

Therefore, in consideration of the above problems, the purpose of the present invention is to provide a non-cleaning rice manufacturing device that can improve the quality of non-cleaning rice by improving the cleaning effect.

An embodiment of the present invention is a non-washing rice manufacturing device comprising at least a polishing unit for mixing and stirring fine grains and water and performing underwater polishing, wherein the polishing unit includes a first water conveying unit, a first fines unit, and a suction unit from the upstream side of the polishing unit. It is a non-cleaning rice manufacturing device consisting of a dehydration unit, a second water transfer unit, and a second scrubbing unit, and bubble water is supplied to the second liquid water transfer unit.

Another embodiment is a scrubbing-free manufacturing device that has a centrifugal dewatering unit capable of dewatering fine particles discharged from the second smelting unit, and wherein the recovered water recovered in the centrifugal dehydrating unit is supplied from the first water smelting conveying unit. .

Another embodiment is a non-cleaning rice production device in which the water supplied to the second water transfer unit is added in an amount of 6 to 24% by weight based on the weight of the fine particles supplied to the second water transfer unit.

According to an embodiment of the present invention, the polishing section is comprised from the upstream side of a first water conveying section, a first semi section, a suction dewatering section, a second water line conveying section, and a second semi section, for example, in the first semi section. It becomes possible to cleanly remove water mixed with used rice bran by the forced action of the suction dehydration unit. And in the next process, the second water transfer unit, water mixed with rice bran from the previous process is not mixed, and bubble water is added to the new clean water, making washing possible in the second washing unit. This improves the cleaning action and improves turbidity and whiteness. In addition, the impact between fine particles is alleviated by air bubbles, and damage to the surface of fine grains leading to underwater cracks can be prevented, making it possible to improve rice quality. It becomes.

At the lower end of the dehydration shaft 19 of the dehydration section 5, a scraping wing (not shown) is mounted on an axis for injecting the fine particles into the moisture adjustment section 6, so that the fine particles can be injected into the moisture adjustment section 6 while diffusing them. . In addition, the dewatering section 5 and the moisture adjusting section 6 are connected by a flow trough 31 whose longitudinal cross section is like a gentle circular arc, and the moisture adjusting section 6 is spread while the fine particles after dewatering are spread together with the scraping blades. It can be put in.

As shown in FIG. 1, the moisture adjusting unit 6 conditions and dries the fine particles by a hot air supply fan 38 with a built-in heater while vibrating them with a vibration motor 37, and cleans them without washing through a genuine duct (not shown). It can be discharged as non-cleaning rice outside of the manufacturing device (1).

Next, the manufacturing process of non-cleaning rice in the non-cleaning rice manufacturing apparatus 1 will be explained in detail, especially based on FIGS. 2 to 5.

Polished rice as a raw material supplied from the raw material supply chute 50 (see FIG. 1) is fed through the passage 52 by the rotary valve 51 (see part A of FIG. 2) in the polished rice supply device 4. A fixed amount is supplied to the fine particle input hopper 42. Then, the fine grains are introduced into the milling well 7 through the fine particle inlet 41 formed on the starting end side (left side of the picture) of the milling well 7.

As shown in Fig. 2, the dewatering unit 3 in this embodiment includes, in order from the upstream side (left side in the drawing), a first water conveying unit (B), a first semi unit (C), a suction dewatering unit (D), It is composed of a second water conveying section (E) and a second fine section (F), and the fine particles discharged from the dewatering section (3) are conveyed to the centrifugal dewatering section (G) on the downstream side.

The fine particles introduced into the milling well 7 are first transported to the first water transfer unit B. 2, 3, etc., a first water supply nozzle 44 is formed in the first water supply conveying unit B at a position downstream of the fine particle inlet 41, and the first water supply nozzle 44 As the addition is performed, the fine particles injected from the fine particle inlet 41 are conveyed downstream (to the right in the drawing) by the conveyance screw 9.

The amount of water added by the first water supply nozzle 44 can be, for example, 6 to 24% by weight (wt%) based on the weight of the injected fine particles. Additionally, in this embodiment, water recovered from the centrifugal dewatering unit G is supplied to the first water nozzle 44 to achieve water reuse. Of course, it is also possible to supply new water without using recovered water.

Next, the fine particles that have been watered in the first hydrated conveying section (B) and conveyed by the conveying screw 9 are conveyed to the first semi-draining portion (C). As described above, a plurality of stirring blades 10 (in the example shown, arranged at two positions at 12 o'clock and 6 o'clock) are formed in the first semi-part C. As a result, the fine particles watered in the first water transfer unit (B) are stirred and ground in the first fine unit (C).

In the semi-process in the first fine section (C), the steel powder generated by stirring and polishing is spread in water, and polishing is also performed by friction between grains in water. At this time, the degree of polishing is 0.5 to 2.0% for the fine grains, so that the aleurone layer on the surface of the fine grains peels off.

Subsequently, the fine particles stirred and ground in the first fine section (C) are transported to the suction dewatering section (D) on the downstream side (right side of the city). A suction fan (not shown) is connected to the suction dehydration unit (D), and a drain pipe 60 for draining the suctioned water is connected. Then, water mixed with rice bran generated in the first fine section C is sucked from the fine grains and discharged to the outside of the machine through the drain pipe 60.

In more detail, as shown in the enlarged perspective view of FIG. 4, a ventilation hole 61 is formed in the milling shaft 8 and the stirring electron 11 near the stirring blade 10 of the suction dehydration unit D. there is. That is, the milling shaft 8 has a hollow structure and communicates with the outside air, and is in communication with the ventilation hole 61. As a result, outside air is introduced into the suction dehydration unit D during suction, making it possible to suction water mixed with rice bran.

Subsequently, the fine particles dehydrated in the suction dehydration unit (D) are transported to the second water transfer unit (E) on the downstream side (right side of the illustration). As shown, a second water supply nozzle 45 and a bubble water supply nozzle 46 are respectively connected to the second water conveying unit E, and bubble water is supplied from the bubble water supply nozzle 46 to the normal water. It is added and configured to be conveyed to the conveyance screw 9 together with the fine particles.

To explain in more detail, in this embodiment, as shown in FIG. 5, a bubble water production device 70 is formed, and the bubble water production device 70 includes a bubble generating device 72 in the water tank 71. It is installed to produce bubble water. The produced bubbled water is configured to be supplied from the bubbled water supply nozzle 46 to the second water conveying unit E through the pump 73 and the control valve 74. In addition, the second water supply nozzle 45 is used to apply water to the inside of the scrubber-free fabrication device 1 when cleaning the scrubber-free fabrication device 1.

By adding bubble water as described above, the fine particles are stirred and polished, and the polishing action further miniaturizes the bubbles and penetrates into details inside the surface of the fine particles. In addition, it becomes possible to promote the peeling of the rice bran inside the surface details of the fine grains and improve the quality such as whiteness and turbidity. In addition, since the rice bran on the fine grain surface details can be peeled off while the “umami component” at the boundary with the starch layer can be left without peeling, the taste can be improved compared to before. In addition, the impact between fine grains is alleviated by the air bubbles, and damage to the surface of the fine grains leading to underwater cracking can be prevented, so it is possible to continuously and stably mass-produce unwashed rice that becomes well-cooked rice rather than soft rice.

As the bubble water, fine bubble water is preferable, and more preferably, ultrafine bubble (registered trademark) water with a bubble diameter of 1 μm or less is used. In this case, it is preferable to add it in an amount of 6 to 15% with respect to the normal water supplied to the second water conveying unit (E).

As shown in FIG. 3, a ring-shaped backflow prevention partition 62 is formed on the outer periphery of the stirring electron 11 between the suction dehydration unit D and the second water transfer unit E. This effectively prevents water mixed with rice bran from entering from the suction dehydration unit (D) into the second water transfer unit (E).

The fine particles watered and conveyed by the second hydrated conveying section (E) are conveyed to the second semi-draining section (F) on the downstream side (right side of the illustration). As shown in FIG. 3 and the like, the second semi-part F is formed with a plurality of stirring blades 10 (in the example shown, arranged at two positions at 12 o'clock and 6 o'clock). That is, since some rice bran remains on the surface of the fine grains dehydrated in the suction dehydration unit (D), clean water is supplied from the second water transfer unit (E), and rinsing is performed in the second semi-fine unit (F). there is.

However, if the fine grains are strongly washed in the second fine part (F), the taste of the rice will deteriorate. Therefore, as shown, the length of the second fine part (F) is made shorter than that of the first fine part (C). , reducing the semi-strength. In addition, in this way, by strongly grinding the rice in the first fine section (C) and lightly grinding it in the second finer section (F), the recovered water discharged and recovered from the centrifugal dewatering section (G) on the downstream side contains rice bran. Fine substances such as etc. are reduced. By doing this, clean recovered water can be supplied from the first water supply nozzle 44, and the semi-smoothing effect in the first semi-part C and the dewatering effect in the suction dewatering part D can be improved. there is.

Additionally, as shown in Figs. 2 and 3, a regulating member 12 is axially mounted on the polishing shaft 8 at the tip of the polishing shaft 8 corresponding to the terminal end of the second semi-part F. The outer diameter of the regulating member 12 is formed by approaching the inner diameter of the milling well 7 and narrowing the gap, so as to restrict the outflow of fine particles from the polishing well 7. The gap between the inner diameter of the rice well 7 and the outer diameter of the regulating member 12 in this embodiment is about 5 to 13 mm. With such a gap size, the fine particles can be conveyed to the centrifugal dewatering unit G while controlling the outflow of the fine particles from the milling well 7. Additionally, the fine strength can be increased by controlling the outflow of fine particles. Thereby, semi-efficiency can be increased. In addition, the inlet port to the dewatering unit 5 is also narrowed, thereby further controlling the outflow of fine particles.

Next, the fine particles conveyed from the second semi-dewatering section (F) are conveyed to the dehydration tank 18 of the dehydrating section 5, as shown in FIG. 2, and are conveyed to the centrifugal dehydrating section G. In the centrifugal dewatering unit G, fine particles and water are transported longitudinally by rotation of the dewatering screw 20 (for example, 1700 rpm). At this time, while the fine particles and water are transferred, they are separated into fine particles and water on the porous wall 17 of the dehydration tank 18 under the action of centrifugal force caused by the rotation (for example, 2000 rpm) of the dehydration tank 18. .

Then, the separated water is recovered through the drain cover 21 and the drain trough 22, and supplied to the first water supply nozzle 44 of the first water conveying unit B as described above, and the recovered water is reused. . On the other hand, the dehydrated fine particles are scraped out from the dehydration tank 18 by a scraping wing (not shown) at the lower end of the dehydration shaft 19, and are fed into the moisture adjustment unit 6 through the down trough 31.

In the moisture adjusting unit 6, the fine particles are driven by the vibration motor 37, hot air is supplied from the hot air supply fan 38, and the fine particles are exposed to the hot air while rotating, thereby performing refining and drying. . And, for example, non-cleaning rice with a moisture content of less than 15% is discharged from a genuine duct (not shown).
