Description
本発明は、無洗米を製造することが可能な、無洗米製造装置に関する。
The present invention relates to a wash-free rice manufacturing apparatus capable of manufacturing wash-free rice.
従来の無洗米製造装置にあっては、特許文献1に開示されているように、1次洗米部と2次洗米部との間、及び、2次洗米部と3次洗米部との間にそれぞれ排水口を設け、3回の洗米を行うことができるものがあった。
In the conventional wash-free rice manufacturing apparatus, as disclosed in Patent Document 1, between the primary rice-washing section and the secondary rice-washing section and between the secondary rice-washing section and the tertiary rice-washing section There was one that provided a drainage port and was able to wash rice three times.
特許文献2には、洗米の後に遠心脱水部を経由させ、無洗米を製造することができる無洗穀粒製造装置が開示されている。
Patent Document 2 discloses a wash-free grain manufacturing apparatus capable of producing wash-free rice by passing the washed rice through a centrifugal dehydrator.
しかしながら、特許文献1に記載された無洗米製造装置の場合、米粒が各排水口上を通過する時間が短いため、米粒と混合した糠混じりの洗米水を各排水口から十分に排水することは難しい。このため、各次洗米工程において洗米水を新たに供給しても、常に糠混じりの洗米水が残存していた。また、上記したような複数回の洗米工程では、米粒同士の擦り合わせによって洗米されるため、糠が研磨材として働き、洗米撹拌する際に米粒表面に小さな傷を付けてしまう。これにより、炊飯時に水中胴割れ(水中亀裂)を生じ、内部澱粉が流出して柔らかいご飯になるという品質面の不安があった。
However, in the case of the rinse-free rice production apparatus described in Patent Document 1, it is difficult to sufficiently drain the rice-washing water mixed with the rice grains and the bran through the drainage ports because the time for the rice grains to pass over the drainage ports is short. . Therefore, even if rice-washing water is newly supplied in each subsequent rice-washing step, rice-washing water mixed with bran always remains. In addition, in the above-described rice washing process, the rice is washed by rubbing the rice grains together, so the bran acts as an abrasive and causes small scratches on the surface of the rice grains when the rice is washed and stirred. As a result, there was a concern about the quality of the rice, as the rice cracked during cooking (underwater cracks) and the internal starch flowed out, resulting in soft rice.
特許文献2に記載された無洗穀粒製造装置にあっては、穀粒(米)を水と混合・撹拌して水中搗精する搗精部(洗米部)と、この後工程に遠心脱水部を設け、無洗米を製造するものであるが、洗米工程が1回であることから、洗い作用が弱かった。
In the non-rinsing grain manufacturing apparatus described in Patent Document 2, a polishing unit (rice washing unit) for mixing and agitating grains (rice) with water and polishing in water, and a centrifugal dehydration unit in the subsequent process. It was used to produce rinse-free rice, but the washing action was weak because the rice was washed only once.
そこで本発明は上記問題点に鑑み、洗米効果を向上させて無洗米の品質を向上させることが可能な、無洗米製造装置を提供することを目的とする。
Therefore, in view of the above problems, it is an object of the present invention to provide a rinse-free rice manufacturing apparatus capable of improving the washing effect and improving the quality of rinse-free rice.

別の実施形態は、前記吸引脱水部は、該吸引脱水部に外気を取り込むことが可能な通気孔を備え、前記第1洗米部で洗米に使用された水を吸引して排水することが可能である無洗米製造装置である。
In another embodiment, the suction dehydration section has a vent hole that allows outside air to be drawn into the suction dehydration section, and the water used for washing rice in the first rice washing section can be sucked and drained. This is the rinse-free rice manufacturing equipment.
別の実施形態は、前記吸引脱水部と前記第2加水搬送部との間には、洗米によって糠混じりの水が前記吸引脱水部から前記第2加水搬送部へ侵入することを防止することが可能な逆流防止隔壁が形成されている無洗米製造装置である。
In another embodiment, water mixed with bran due to washing of rice is prevented from entering from the suction dewatering unit to the second water conveying unit between the suction dehydrating unit and the second water conveying unit. It is a rinse-free rice manufacturing apparatus in which a possible backflow prevention partition is formed.
別の実施形態は、前記第2洗米部から排出された米粒を脱水することが可能な遠心脱水部を有し、前記遠心脱水部において回収された回収水は、前記第1加水搬送部において供給される無洗米製造装置である。
Another embodiment has a centrifugal dewatering unit capable of dehydrating the rice grains discharged from the second rice washing unit, and the recovered water collected in the centrifugal dewatering unit is supplied to the first water transfer unit. This is a wash-free rice manufacturing device that

Another embodiment is a rinse-free rice manufacturing apparatus in which the intensity of rice washing in the second rice washing section is lower than that in the first rice washing section.
本発明の実施形態によれば、搗精部を上流側から第1加水搬送部、第1洗米部、吸引脱水部、第2加水搬送部、第2洗米部で構成することにより、例えば、第1洗米部で使用された糠混じりの水を、吸引脱水部における強制作用によってきれいに除去することが可能となる。さらに次工程の第2加水搬送部では、前工程の糠混じりの水が混入することなく、新しいきれいな水が添加されて第2洗米部で洗米が可能となる。これにより、洗い作用が向上し、濁度や白度を向上させることができるほか、糠混じりの水によって米粒表面を傷付けることを抑制して米飯品質を向上させることが可能となる。

Furthermore, in the second water supply conveying section in the next step, the rice can be washed in the second rice washing section by adding fresh clean water without mixing the water mixed with rice bran in the previous step. As a result, the washing action is improved, turbidity and whiteness can be improved, and the rice grain surface can be prevented from being damaged by water mixed with bran, thereby improving the quality of cooked rice.

As shown in FIG. 1, the moisture adjusting unit 6 vibrates rice grains with a vibrating motor 37, refines and dries rice grains with a hot air supply fan 38 using a heater as a heat source, and heats the rice grains through a refined product duct (not shown). 1 can be discharged out of the machine as rinse-free rice.
次に、無洗米製造装置1における無洗米の製造工程について、特に図2~図4に基づいて詳細に説明する。
Next, the process of manufacturing rinse-free rice in the rinse-free rice manufacturing apparatus 1 will be described in detail, especially with reference to FIGS. 2 to 4.
原料供給シュート50(図1参照)から供給される原料となる精白米は、精白米供給装置4におけるロータリバルブ51(図2のA部参照)によって通路52を介して米粒投入ホッパ42に定量供給される。そして、搗精筒7の始端側(図示左側)に設けられた米粒投入口41を介して米粒が搗精筒7内に投入される。
Polished rice as a raw material supplied from a raw material supply chute 50 (see FIG. 1) is quantitatively supplied to a rice grain charging hopper 42 through a passage 52 by a rotary valve 51 (see section A in FIG. 2) in the polished rice supply device 4. be done. Then, rice grains are thrown into the polishing barrel 7 through a rice grain inlet 41 provided on the starting end side (left side in the drawing) of the polishing barrel 7 .
本実施例の搗精部3は、図2に示されるように上流側(図示左側)から順に、第1加水搬送部B、第1洗米部C、吸引脱水部D、第2加水搬送部E、第2洗米部Fで構成され、搗精部3から排出された米粒は、下流側の遠心脱水部Gへと搬送される。
As shown in FIG. 2, the polishing section 3 of the present embodiment includes, in order from the upstream side (left side in the drawing), a first water-addition conveying section B, a first rice-washing section C, a suction dehydration section D, a second water-addition conveying section E, The rice grains discharged from the second rice washing section F and the polishing section 3 are conveyed to the centrifugal dewatering section G on the downstream side.
搗精筒7内に投入された米粒は、まず第1加水搬送部Bへ運ばれる。図2、3等に記載されるように、第1加水搬送部Bには米粒投入口41の下流側の位置に第1給水ノズル44が設けられており、当該第1給水ノズル44から加水が行われるとともに、米粒投入口41から投入された米粒が搬送スクリュー9で下流(図示右側)方向に搬送される。
The rice grains put into the milling cylinder 7 are first conveyed to the first water conveying section B. As shown in FIGS. 2, 3, etc., the first water supply nozzle 44 is provided in the first water supply conveying part B at a position downstream of the rice grain input port 41, and water is supplied from the first water supply nozzle 44. At the same time, the rice grains input from the rice grain input port 41 are conveyed downstream (right side in the drawing) by the conveying screw 9 .
第1給水ノズル44による加水の量は、例えば投入される米粒の重量に対して10~20重量%(wt%)とすることができる。また、本実施例では、遠心脱水部Gで回収された回収水を第1給水ノズル44に供給して水の再利用を図っている。もちろん、回収水を使用せずに新しい水を供給することも可能である。
The amount of water added by the first water supply nozzle 44 can be, for example, 10 to 20% by weight (wt%) with respect to the weight of rice grains to be fed. Further, in this embodiment, the recovered water recovered by the centrifugal dehydrator G is supplied to the first water supply nozzle 44 to reuse the water. Of course, it is also possible to supply fresh water without using recovered water.
次に、第1加水搬送部Bで加水され、搬送スクリュー9によって搬送された米粒は、第1洗米部Cに運ばれる。第1洗米部Cには前述したように複数の撹拌羽根10(図示される例では12時方向と6時方向の2箇所に配置)が設けられている。これにより、第1加水搬送部Bで加水された米粒が第1洗米部Cにおいて撹拌・洗米される。
Next, the rice grains that have been watered in the first hydrating conveying section B and conveyed by the conveying screw 9 are conveyed to the first rice washing section C. As described above, the first rice-washing section C is provided with a plurality of stirring blades 10 (in the illustrated example, arranged at two locations, 12 o'clock and 6 o'clock). As a result, the rice grains added with water in the first water feeding section B are agitated and washed in the first rice washing section C.
第1洗米部Cにおける洗米工程では、撹拌・洗米により生じた糠分が水中に拡散されるとともに、水中における粒どうしの摩擦により搗精も行われる。このときの搗精度合は米粒に対して0.5~2.0%進行することで米粒表面のアリューロン層が剥がれ落ちることになる。
In the rice washing process in the first rice washing section C, the bran content generated by stirring and washing the rice is dispersed in the water, and polishing is also performed by the friction between the grains in the water. At this time, when the degree of polishing progresses by 0.5 to 2.0% with respect to the rice grain, the aleurone layer on the surface of the rice grain is peeled off.
続いて第1洗米部Cで撹拌・洗米された米粒は、下流側(図示右側)の吸引脱水部Dへと運ばれる。当該吸引脱水部Dには、不図示の吸引ファンが接続されるとともに、吸引した水を排水する排水管60が接続されている。そして、第1洗米部Cで発生した糠混じりの水を、米粒から吸引するとともに排水管60により機外へ排出している。
Subsequently, the rice grains stirred and washed in the first rice washing section C are transported to the suction dehydration section D on the downstream side (on the right side in the drawing). A suction fan (not shown) is connected to the suction dewatering unit D, and a drain pipe 60 for draining the sucked water is connected. The water mixed with rice bran generated in the first rice washing section C is sucked from the rice grains and discharged to the outside of the machine through the drain pipe 60 .
より詳細に説明すると、吸引脱水部Dの撹拌羽根10近傍の搗精軸8及び撹拌転子11には、図4の拡大斜視図に示されるように通気孔61が設けられている。すなわち、搗精軸8は中空構造となって外気と通じており、当該通気孔61と連通している。これにより、吸引の際に吸引脱水部Dへ外気が取り込まれ、糠混じりの水の吸引を可能にしている。
More specifically, the polishing shaft 8 and the stirring roller 11 in the vicinity of the stirring blades 10 of the suction dewatering section D are provided with vent holes 61 as shown in the enlarged perspective view of FIG. That is, the polished shaft 8 has a hollow structure and communicates with the outside air, and communicates with the ventilation hole 61 . As a result, outside air is taken into the suction dehydration part D at the time of suction, and water mixed with rice bran can be sucked.
続いて、吸引脱水部Dで脱水された米粒は、下流側(図示右側)の第2加水搬送部Eへと運ばれる。第2加水搬送部Eには図示されるように第2給水ノズル45が接続されており、当該第2給水ノズル45によって加水しながら搬送スクリュー9で米粒を搬送する。なお、吸引脱水部Dと第2加水搬送部Eとの間の撹拌転子11の外周には、図3に示されるよう、リング状の逆流防止隔壁62が形成されており、これにより、吸引脱水部Dから第2加水搬送部Eへ糠混じりの水が侵入することを防いでいる。
Subsequently, the rice grains dehydrated in the suction dewatering section D are conveyed to the second hydration conveying section E on the downstream side (right side in the drawing). A second water supply nozzle 45 is connected to the second water supply conveying part E as shown in the figure, and the rice grains are conveyed by the conveying screw 9 while water is added by the second water supply nozzle 45 . In addition, as shown in FIG. 3, a ring-shaped backflow prevention partition wall 62 is formed on the outer circumference of the stirring roller 11 between the suction dehydration section D and the second hydration conveying section E. Intrusion of water mixed with rice bran from the dewatering section D into the second hydration conveying section E is prevented.
第2加水搬送部Eによって加水されて搬送された米粒は、下流側(図示右側)の第2洗米部Fへと運ばれる。第2洗米部Fは図3等に示されるように、複数の撹拌羽根10(図示される例では12時方向と6時方向の2箇所に配置)が設けられている。すなわち、吸引脱水部Dで脱水された米粒の表面には、わずかに糠が残っているため、第2加水搬送部Eできれいな水を供給し、第2洗米部Fですすぎを行っている。
The rice grains that have been watered and conveyed by the second water supply conveying section E are conveyed to the second rice washing section F on the downstream side (on the right side in the drawing). As shown in FIG. 3 and the like, the second rice-washing section F is provided with a plurality of stirring blades 10 (arranged at two locations, 12 o'clock and 6 o'clock in the illustrated example). That is, since a small amount of bran remains on the surface of the rice grains dehydrated in the suction dewatering section D, clean water is supplied in the second water supply conveying section E, and rinsing is performed in the second rice washing section F.
ただし、第2洗米部Fで米粒を強く洗ってしまうと、米飯の食味が悪くなるため、図示されるように、第1洗米部Cよりも第2洗米部Fの長さを短くして、洗米強度を低下させている。またこのようにして、第1洗米部Cで洗米を強く行い、第2洗米部Fで弱く洗米することで、下流側の遠心脱水部Gで排出されて回収される回収水には、糠などの微細な物質の含有量が少なくなる。そうすることで、第1給水ノズル44できれいな回収水を供給することができ、第1洗米部Cにおける洗米効果や、吸引脱水部Dにおける脱水効果の向上を図ることができる。
However, if the rice grains are washed strongly in the second rice-washing part F, the taste of the cooked rice deteriorates. It reduces the strength of rice washing. In this way, the rice is washed strongly in the first rice-washing section C and weakly washed in the second rice-washing section F, so that the collected water discharged and collected in the centrifugal dehydration section G on the downstream side contains rice bran, etc. content of fine substances is reduced. By doing so, clean recovered water can be supplied by the first water supply nozzle 44, and the rice washing effect in the first rice washing section C and the dewatering effect in the suction dewatering section D can be improved.
また、第2洗米部Fの終端にあたる搗精軸8の先端部には、図2及び図3に示されるように、規制部材12が搗精軸8に軸着されている。当該規制部材12の外径は搗精筒7の内径に接近させて隙間を狭めて設けられており、搗精筒7から米粒が流出することを規制するものである。本実施例における搗精筒7の内径と、規制部材12の外径との隙間は、5~13mm程度である。このような隙間寸法とすることによって、搗精筒7から米粒の流出を規制しつつ、遠心脱水部Gへ米粒を搬送することができる。また、米粒の流出を規制することにより、洗米強度を高めることができる。これにより、洗米効率を高めることができる。また、脱水部5への投入口も狭めることにより、さらに米粒の流出を規制する。
At the end of the polishing shaft 8 at the end of the second rice washing section F, a regulating member 12 is attached to the polishing shaft 8, as shown in FIGS. The restricting member 12 has an outer diameter close to the inner diameter of the milling cylinder 7 to narrow the gap, and restricts the outflow of rice grains from the milling cylinder 7 . The gap between the inner diameter of the polishing cylinder 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 rice grains can be conveyed to the centrifugal dehydrator G while controlling the outflow of the rice grains from the polishing cylinder 7 . Also, by restricting the outflow of rice grains, it is possible to increase the intensity of washing the rice. Thereby, the rice washing efficiency can be improved. In addition, by narrowing the inlet to the dewatering unit 5, the outflow of rice grains is further restricted.
次に、第2洗米部Fから搬送された米粒は、図2に示されるように脱水部5の脱水筒18に運ばれて、遠心脱水部Gへと搬送される。遠心脱水部Gでは米粒と水とが脱水スクリュー20の回転(例えば、1700rpm)により縦方向へ移送される。このとき、米粒と水は移送されながら、脱水筒18の回転(例えば、2000rpm)による遠心力の作用を受けて、脱水筒18の多孔壁17において米粒と水とに分離される。
Next, the rice grains conveyed from the second rice washing section F are conveyed to the dehydrating cylinder 18 of the dehydrating section 5 and conveyed to the centrifugal dehydrating section G as shown in FIG. In the centrifugal dewatering section G, the rice grains and water are transported vertically by the rotation of the dewatering screw 20 (for example, 1700 rpm). At this time, the rice grains and water are separated into rice grains and water at the perforated wall 17 of the dewatering cylinder 18 while being transferred, under the effect of centrifugal force due to the rotation of the dewatering cylinder 18 (eg, 2000 rpm).
そして、分離された水は排水カバー21及び排水樋22を介して回収され、前述したように第1加水搬送部Bの第1給水ノズル44に供給して回収水は再利用される。一方、脱水された米粒は、脱水軸19下端の不図示の掻き出し羽根により脱水筒18から掻き出され、流下樋31を介して水分調整部6へ投入される。
Then, the separated water is recovered through the drainage cover 21 and the drainage gutter 22, and supplied to the first water supply nozzle 44 of the first water supply conveying section B as described above, and the recovered water is reused. On the other hand, the dehydrated rice grains are scraped out of the dehydration cylinder 18 by scraping blades (not shown) at the lower end of the dehydration shaft 19 and thrown into the moisture adjusting section 6 via the downflow trough 31 .
水分調整部6では、米粒が振動モータ37によって転動され、熱風供給ファン38からの熱風が送給されて、米粒を転動させながら熱風に曝(さら)されることにより、調質・乾燥が行われる。そして、不図示の精品ダクトからは、例えば、水分が15%未満に仕上げられた無洗米が排出される。
In the moisture adjusting unit 6, the rice grains are rolled by the vibration motor 37, hot air is supplied from the hot air supply fan 38, and the rice grains are rolled and exposed to the hot air, thereby being tempered and dried. is done. Wash-free rice with a water content of less than 15%, for example, is discharged from a refined product duct (not shown).

前述の実施例では、第1洗米部C及び吸引脱水部D、第2洗米部Fに設けた撹拌羽根10を、搗精軸8に対して12時方向と6時方向の2箇所に配置した。しかし、必ずしもこのような配置態様に限定されるものではなく、さらに複数箇所に撹拌羽根10を設けるようにしてもよいし、撹拌羽根10を搗精軸8の軸方向に複数分割して配置することも可能である。これにより、搗精部3内の内部抵抗が調整可能になり、洗いやすすぎの程度を調整することが可能となる。
In the above-described example, the stirring blades 10 provided in the first rice washing section C, the suction dehydration section D, and the second rice washing section F were arranged at two positions in the direction of 12 o'clock and 6 o'clock with respect to the polishing shaft 8 . However, it is not necessarily limited to such an arrangement mode, and the stirring blades 10 may be provided at a plurality of locations, or the stirring blades 10 may be divided into a plurality of parts in the axial direction of the polishing shaft 8 and arranged. is also possible. As a result, the internal resistance in the polishing section 3 can be adjusted, and the degree of washing and rinsing can be adjusted.
例えば、第1洗米部C及び/又は吸引脱水部Dの撹拌羽根10の配置構成と、第2洗米部Fに設けた撹拌羽根10の配置構成を異ならせることによって、下流側の第2洗米部Fにおける内部抵抗を低くすることができる。これにより、上流側の第1洗米部Cで積極的に洗米し、下流側の第2洗米部Fですすぎを兼ねた洗米を行うことが可能となり、より効率的に洗米が行われて、洗い作用が良好となる。
For example, by making the arrangement configuration of the stirring blades 10 of the first rice washing section C and/or the suction dewatering section D different from the arrangement configuration of the stirring blades 10 provided in the second rice washing section F, the second rice washing section on the downstream side The internal resistance at F can be lowered. As a result, it is possible to actively wash the rice in the first rice-washing section C on the upstream side and wash the rice in the second rice-washing section F on the downstream side, which also serves as rinsing. It works better.
