Description

本発明は、家庭の台所などにおいて玄米を必要量ごとに手軽に精米することのできる家庭用精米機に関する。   The present invention relates to a domestic rice milling machine capable of easily milling brown rice for each necessary amount in a home kitchen or the like.

従来から家庭用の精米機は種々提案されており、例えば、本出願人の特許文献1乃至2のようなものがある。特許文献1乃至2に開示される家庭用精米機は、除糠用多孔壁を備えた臼形容器と、これを包囲する集糠容器とを、ほぼ円筒状の外枠内に着脱自在に収容して、その開放上部を蓋で被覆するとともに、前記臼形容器の底部中央には撹拌用突片を備えた縦軸を立設し、前記外枠の下方には、前記縦軸を駆動させる駆動手段を内蔵したものであり、必要量の玄米を前記臼形容器に投入し、蓋を被せてスイッチがオンして駆動手段を起動し、撹拌用突片の回転による遠心力による玄米の臼形容器への投げ出しと玄米どうしの粒々摩擦により精米が行われるものである。   Conventionally, various rice milling machines for home use have been proposed, for example, Patent Documents 1 and 2 of the present applicant. The domestic rice milling machine disclosed in Patent Literatures 1 and 2 detachably accommodates a mortar-shaped container having a porous wall for removing the debris and a collecting container surrounding the mortar-shaped container in a substantially cylindrical outer frame. The upper open portion is covered with a lid, and a vertical axis provided with a stirring protrusion is provided at the center of the bottom of the mortar-shaped container, and the vertical axis is driven below the outer frame. The drive means is built-in, the necessary amount of brown rice is put into the mortar-shaped container, the lid is put on, the switch is turned on to start the drive means, and the brown rice mortar by centrifugal force due to the rotation of the stirring protrusion Rice milling is carried out by throwing it into a shaped container and rubbing the grains of brown rice.

上述に記載の家庭用精米機は必要量の精米が可能ではあるが、米表面にわずかに糠が付着した状態にあり、炊飯する際には前もって米を洗う必要がある。しかし、この洗米工程は炊飯後の米の食味を左右する重要な工程ではあるが、非常に手間のかかる工程でもある。この工程の省力化を図るべく、ブラシを用いて乾式で研米する簡易的な研米機も存在するが(例えば、特許文献3参照)、水を使って洗米するものに比較して糠の除去性能が劣るという問題がある。   Although the above-described household rice milling machine can produce the necessary amount of rice, it is in a state where rice cake is slightly attached to the surface of the rice, and it is necessary to wash the rice before cooking. However, this rice washing process is an important process that affects the taste of rice after cooking, but is also a very time-consuming process. In order to save labor in this process, there is a simple rice polishing machine that uses a brush to dry-grind rice (see, for example, Patent Document 3), but compared to those that use water to wash rice. There is a problem that the removal performance is inferior.

According to the invention of claim 2,
In order to solve the above-mentioned problems, a first aspect of the present invention is a collecting container that is removably accommodated in a main body, a rice milling container that is accommodated in the collecting container, and a center of the bottom of the rice milling container. When the rice milling is started, it has a vertical axis that is erected and a stirring shaft for rice milling that is mounted on the vertical axis and radially arranges a plurality of stirring projection pieces toward the rice milling vessel. The rice grains in the milled rice vessel are stirred by the stirring projecting pieces by the rotation of the milling shaft for rice milling, and pressed against the porous wall for removal that is formed on the inner peripheral wall of the rice milling vessel, and are separated from the rice grains. Is a household rice mill formed so as to leak from the porous wall for degreasing and be collected in the collecting container, and a humidifying part for adding moisture to the rice grains in the polished rice in the polished rice container, and a desired The amount of water added and the timing of addition depending on the set values of the degree of milling and the amount of polished rice And a control unit that controls the humidification unit, and when the degree of milling is set to germinated rice, the control unit drives the humidification unit immediately after the start of the rice milling when the moisture addition timing is set. Technical measures were taken to do.

According to the invention of claim 3,
In the invention of claim 1, when the degree of milling is set to white rice, the control unit determines the addition timing of the water to 5 seconds from 15 seconds before the end of milling to 10 seconds before The humidifier is driven.

さらに、請求項記載の発明によれば、上記請求項1の発明において、前記制御部は、精白度が胚芽米に設定された場合に、前記水分の添加タイミングを精米開始直後から5秒までの5秒間に決定し前記加湿部を駆動するものである。 Furthermore, according to the invention of claim 4, in the invention of claim 1, when the degree of milling is set to germinated rice, the control unit sets the water addition timing from immediately after the start of milling to 5 seconds. Is determined for 5 seconds, and the humidifying unit is driven.

そして、請求項記載の発明によれば、前記制御部は、米粒に添加する水分の温度を50〜55℃の範囲に設定するものである。 And according to invention of Claim 5 , the said control part sets the temperature of the water | moisture content added to a rice grain to the range of 50-55 degreeC.

また、請求項記載の発明によれば、前記制御部は、米粒に添加する水分の添加量を原料となる玄米重量に対して0.4〜0.8%の範囲に設定するものである。 According to the invention of claim 6 , the control unit sets the amount of water added to the rice grains in a range of 0.4 to 0.8% with respect to the weight of the brown rice as a raw material. .

請求項1記載の発明によれば、精米が開始されると、精米用撹拌軸の回転により、精米容器内の米粒が攪拌されるとともに、精米容器の内周壁に押し付けられ、転動しながら姿勢が変えられ、均等な精米が行われる。次いで、精米開始から一定時間経過すると(精米量の設定値が1合及び2合の場合は115秒後、3合の場合は165秒後、4合の場合は225秒後、5合の場合は285秒後)、加湿部から水分が添加される。水分の添加が行われると、米粒表面に付着した糠分が軟質化され、米粒が攪拌されることで研磨作用が生じる。すなわち、米粒同士が相互に擦(こす)れ合って糠分が剥離されるとともに、米粒表面の凹凸がなくなり、米粒表面には白い光沢が生じ、糠の除去性能が極めて優れた無洗米に仕上げることができるのである。   According to the first aspect of the present invention, when rice milling is started, the rice grains in the rice milling vessel are stirred by the rotation of the milling shaft for rice milling, and are pressed against the inner peripheral wall of the rice milling container, while rolling. Is changed and evenly polished rice is made. Next, when a certain period of time has elapsed since the start of rice polishing (if the set value of the rice polishing is 1 go and 2 go, 115 seconds later, 3 go after 165 seconds, 4 go after 225 seconds, 5 go 285 seconds later), moisture is added from the humidifying part. When moisture is added, the soot adhering to the surface of the rice grains is softened, and the rice grains are agitated to produce a polishing action. That is, the rice grains are rubbed against each other and the koji is peeled off, and the surface of the rice grains is free of irregularities, white gloss is generated on the surface of the rice grains, and finishes with no-wash rice with extremely excellent koji removal performance. It can be done.

また、本発明の請求項2記載の発明によれば、
前記制御部が、精白度が胚芽米に設定された場合に、前記水分の添加タイミングを精米開始直後に前記加湿部を駆動するものであるから、精米終期に水分を添加することに比べて駆動モータにかかる負荷が増大する問題があるが、精米作用が抑えられる効果があり、米粒の先端部に位置する胚芽の脱落が軽減されて胚芽残存率を高めることができる。

また、本発明の請求項3記載の発明によれば
前記制御部が、精白度が白米に設定された場合に、前記水分の添加タイミングを精米の終了直前の15秒前から10秒前までの5秒間に決定し前記加湿部を駆動するものであるから、精米初期に水分を添加することに比べて駆動モータにかかる負荷を軽減できる効果がある。また、玄米の表面を覆う糠分となる果皮や種皮がほぼ完全に除去され、胚乳部となる糊粉層が露出した時期に水分が添加されるため、糠の除去効率がよく、研磨作用をスムーズに行うことができる。
According to the invention of claim 2 of the present invention,
When the degree of milling is set to germinated rice, the control unit drives the humidifying unit immediately after the start of rice milling, so that it is driven compared to adding water at the end of rice milling. Although there is a problem that the load applied to the motor increases, there is an effect that the rice milling action is suppressed, dropout of the germ located at the tip of the rice grain is reduced, and the embryo remaining rate can be increased.

Further, according to the invention of claim 3 of the present invention, when the degree of milling is set to white rice, the control unit sets the water addition timing from 15 seconds before the end of milling to 10 seconds. Since the humidifying unit is driven for 5 seconds before the second, there is an effect that the load applied to the drive motor can be reduced as compared with the case where moisture is added at the early stage of milling. In addition, the skin and seed coat that covers the surface of the brown rice is almost completely removed, and moisture is added when the paste layer that becomes the endosperm part is exposed. It can be done smoothly.

さらに、本発明の請求項記載の発明によれば、前記制御部が、精白度が胚芽米に設定された場合に、前記水分の添加タイミングを精米開始直後から5秒までの5秒間に決定し前記加湿部を駆動するものであるから、精米終期に水分を添加することに比べて駆動モータにかかる負荷が増大する問題があるが、精米作用が抑えられる効果があり、米粒の先端部に位置する胚芽の脱落が軽減されて胚芽残存率を高めることができる。 Furthermore, according to the invention described in claim 4 of the present invention, when the degree of milling is set to germinated rice, the control unit determines the timing of adding the water to 5 seconds from immediately after the start of rice milling to 5 seconds. However, since it drives the humidification part, there is a problem that the load applied to the drive motor is increased compared to adding moisture at the end of the milling process, but there is an effect that the milling action is suppressed, and at the tip of the rice grain Dropping of the located germ can be reduced and the germ survival rate can be increased.

そして、本発明の請求項記載の発明によれば、前記制御部が、米粒に添加する水分の温度を50〜55℃の範囲に設定するものであるから、精米による温度上昇と水温との温度較差による胴割れの発生を軽減することができる。 And according to invention of Claim 5 of this invention, since the said control part sets the temperature of the water | moisture content added to a rice grain in the range of 50-55 degreeC, the temperature rise by milled rice and water temperature are set. It is possible to reduce the occurrence of shell cracks due to temperature difference.

また、本発明の請求項記載の発明によれば、前記制御部が、米粒に添加する水分の添加量を原料となる玄米重量に対して0.4〜0.8%の範囲に設定するものであり、原料となる玄米重量に対して水分の適切な添加量が添加され、極めて良好な研磨作用を実現することができる。 Moreover, according to invention of Claim 6 of this invention, the said control part sets the addition amount of the water | moisture content added to a rice grain to the range of 0.4-0.8% with respect to the brown rice weight used as a raw material. Therefore, an appropriate amount of moisture is added to the weight of the brown rice used as a raw material, and an extremely good polishing action can be realized.

As shown in FIG. 4, the operation panel 40 including a touch panel includes an operation start / stop switch 42, a whitening rice mode switch 43, and a whiteness setting switch 44. Each time the whiteness setting switch 44 is pressed, an LED display 45 for sequentially lighting and displaying “white rice”, “3 minutes”, “5 minutes”, “embryo” and “re-milled rice”, The amount setting switch 46 for setting the amount and the points “1 go”, “2 go”, “3 go”, “4 go” and “5 go” are sequentially lit each time the amount setting switch 46 is pressed once. An LED display unit 47 for displaying is provided.

次に、本発明の家庭用精米機の精米動作につき、原料として玄米を投入したときを説明する。まず、筐体2の上部に被着している上蓋10を取り外し、台所などの給水設備に移動する。そして、上蓋10のキャップ12を外して水タンク11に水を注水する。水の必要量としては原料となる玄米が約1合(158[g]:180[ml]×1[合]×0.88[比重])の場合、約3.0[g](=3.0[ml])、玄米が約3合(475[g]:180[ml]×3[合]×0.88[比重]) の場合、約9.0[g](=9.0[ml])、玄米が約5合(792[g]:180[ml]×5[合]×0.88[比重])の場合、約15.0[g](=15.0[ml])で十分である。これは、原料玄米(例えば、水分14.0%)を精米するうちに蒸発する水分(例えば0.5%程度)を噴霧により加水し、精米後の精品とすると、例えば、水分を14.5%に仕上げる水量をあらかじめ計算によって求めるとよい。しかしながら、加湿部7の噴霧ノズル13や電磁弁14の作動に支障がないよう、水タンク11にはほぼ満量に近い水量を注水するのが好ましい。   Next, when brown rice is used as a raw material for the rice milling operation of the household rice mill of the present invention will be described. First, the upper lid 10 attached to the upper part of the housing 2 is removed and moved to a water supply facility such as a kitchen. Then, the cap 12 of the upper lid 10 is removed and water is poured into the water tank 11. The required amount of water is about 3.0 [g] (= 3.0 [ml]) when the brown rice used as a raw material is about 1 go (158 [g]: 180 [ml] x 1 [go] x 0.88 [specific gravity]) , Brown rice is about 3 go (475 [g]: 180 [ml] x 3 [go] x 0.88 [specific gravity]), about 9.0 [g] (= 9.0 [ml]), brown rice is about 5 go (792 [g]: 180 [ml] × 5 [total] × 0.88 [specific gravity]), about 15.0 [g] (= 15.0 [ml]) is sufficient. This is because water that evaporates while the raw brown rice (for example, 14.0% of water) is milled is sprayed to obtain a refined product after milling, for example, the amount of water that finishes the water to 14.5%. Should be calculated in advance. However, it is preferable to fill the water tank 11 with a water amount that is almost full so as not to hinder the operation of the spray nozzle 13 and the electromagnetic valve 14 of the humidifying unit 7.

水タンク11への注水が完了すると、筐体2のヒンジ9に上蓋10を被着するとともに、筐体2の内枠24に集糠容器25及び精米容器26を収容し(図5参照)、次いで、精米容器26内の縦軸27に精米用撹拌軸29を嵌合させておく。そして、所望の量の玄米を精米容器26に投入し、上蓋10の閉蓋操作を行う。この閉蓋操作を行うことで安全スイッチ36がオンとなり、駆動モータ3が起動できる状態となる。   When water injection into the water tank 11 is completed, the upper lid 10 is attached to the hinge 9 of the housing 2 and the collecting container 25 and the rice milling container 26 are accommodated in the inner frame 24 of the housing 2 (see FIG. 5). Next, the milling shaft 29 for rice polishing is fitted to the vertical axis 27 in the rice milling container 26. Then, a desired amount of brown rice is put into the milled rice vessel 26 and the upper lid 10 is closed. By performing this closing operation, the safety switch 36 is turned on, and the drive motor 3 can be activated.

次に、操作パネル40の量設定スイッチ45を所望の値に設定し、白さ設定スイッチ43を「白米」に設定した後、美白米モードスイッチ42及び運転開始・停止スイッチ34をオンすると、通常の精米が終了する前の数秒の間、水分を噴霧して米粒表面に付着した糠分を軟らかくし、米粒同士の研磨を実行後に精米を完了させる「美白米モード」が開始されることになる。   Next, after the amount setting switch 45 of the operation panel 40 is set to a desired value and the whiteness setting switch 43 is set to “white rice”, the whitening rice mode switch 42 and the operation start / stop switch 34 are turned on. For a few seconds before the rice milling is finished, the “whitening rice mode” will be started, which will spray the moisture to soften the scum adhering to the surface of the rice grain and complete the milling after the polishing of the rice grains. .

表1は玄米を白米に精白する際に「美白米モード」を追加して実行したときの制御を示す仕様図である。表1において、例えば、量設定が1合の場合は、総精米時間130秒の全区間を通して精米用撹拌軸29が回転数2200rpmで精米が行われる。そして、精米開始から115秒までの区間は通常の精米が行われ、精米開始から115秒から120秒までの区間(5秒間)は水分を噴霧しながら精米が行われ、その後、120秒から130秒までの区間(10秒間)は水分の噴霧なしで研磨されることを示している。また、量設定が5合の場合は、総精米時間300秒のうち、精米開始から50秒までの区間は精米用撹拌軸29が回転数2200rpmで精米が行われ、50秒から300秒までの区間は精米用撹拌軸29が回転数2200rpmで精米が行われることを示している。そして、精米開始から285秒から290秒までの区間(5秒間)は水分を噴霧しながら精米が行われ、その後、290秒から300秒までの区間(10秒間)は水分の噴霧なしで研磨されることを示している。   Table 1 is a specification diagram showing control when the “whitening rice mode” is added and executed when the brown rice is refined into white rice. In Table 1, for example, when the amount setting is 1, the rice milling is performed at a rotational speed of 2200 rpm through the entire milling time of the milling time of 130 seconds. In the section from the start of rice milling to 115 seconds, normal rice milling is performed. In the section from the start of rice polishing to 115 seconds to 120 seconds (5 seconds), the rice milling is performed while spraying water, and then from 120 seconds to 130 seconds. The section up to the second (10 seconds) indicates that the polishing is performed without spraying moisture. In addition, when the amount setting is 5 go, of the total milling time of 300 seconds, in the section from the start of the milling to 50 seconds, the milling shaft 29 for milling is polished at a rotational speed of 2200 rpm, and from 50 to 300 seconds. The section shows that rice milling is performed at a rotational speed of 2200 rpm with the milling shaft 29 for rice milling. Then, during the period from 285 seconds to 290 seconds (5 seconds) from the start of the rice milling, the rice milling is performed while spraying moisture, and thereafter the section from 290 seconds to 300 seconds (10 seconds) is polished without spraying moisture. Which indicates that.

図2を参照して説明すると、精米が開始されると、精米用撹拌軸29の回転により、精米容器26内の米粒は、攪拌用突片28によって攪拌されるとともに、精米容器26の内周壁に押し付けられ、転動しながら姿勢が変えられ、均等な精米が行われる。次いで、精米開始から一定時間経過すると(1合及び2合の場合は115秒、3合の場合は165秒、4合の場合は225秒、5合の場合は285秒)、加湿部7から水分が噴霧される。すなわち、一定時間経過すると、電磁弁14及び噴霧ノズル13が作動し、ノズル13から精米容器26内の米粒に向けて水が噴霧される。このとき、精米による温度上昇(例えば、粒々摩擦により精米時は40〜50℃に米温が上がる。)と水温との温度較差により胴割れが生じないよう、あらかじめ加温ヒータ15によって水温が50〜55℃の範囲に保持された温水が噴霧されることになる。水の噴霧量としては、白さ設定スイッチ43を「白米」に設定した場合、原料となる玄米重量に対し、0.4〜0.8%が好ましく、より好ましくは、0.5〜0.7%がよい。噴霧時間としては精米が終了する15秒前から10秒前の5秒間に制限するのがよい。   Referring to FIG. 2, when rice milling is started, the rice grains in the rice milling container 26 are stirred by the stirring protrusions 28 and the inner peripheral wall of the rice milling container 26 by the rotation of the rice milling stirring shaft 29. Is pressed, and the posture is changed while rolling, and even rice milling is performed. Next, when a certain time has passed since the start of the rice polishing (115 seconds for 1 go and 2 go, 165 seconds for 3 go, 225 seconds for 4 go, 285 seconds for 5 go), the humidifying unit 7 Moisture is sprayed. That is, when a certain period of time elapses, the electromagnetic valve 14 and the spray nozzle 13 are operated, and water is sprayed from the nozzle 13 toward the rice grains in the rice milling container 26. At this time, the water temperature is set to 50 by the warming heater 15 in advance so as not to cause shell cracking due to the temperature difference between the temperature rise due to milled rice (for example, the rice temperature rises to 40-50 ° C. during grain milling during grain milling) and the water temperature. Hot water kept in the range of ˜55 ° C. will be sprayed. When the whiteness setting switch 43 is set to “white rice”, the amount of water sprayed is preferably 0.4 to 0.8%, more preferably 0.5 to 0.00%, based on the brown rice weight as a raw material. 7% is good. The spraying time is preferably limited to 5 seconds from 15 seconds to 10 seconds before the completion of the rice polishing.

上記のように水分の噴霧が行われると、米粒表面に付着した糠分が軟質化される。そして、精米終了まで精米が継続され、米粒が攪拌されることで研磨作用が生じる。すなわち、米粒同士が相互に擦(こす)れ合って糠分が剥離されるとともに、米粒表面の凹凸がなくなって米粒表面に光沢が生じるようになる。   When moisture is sprayed as described above, the soot adhering to the surface of the rice grain is softened. And polishing is continued because rice polishing is continued until the completion of rice polishing and the rice grains are stirred. That is, the rice grains are rubbed against each other and the cocoons are peeled off, and the irregularities on the surface of the rice grains are eliminated, resulting in a gloss on the surface of the rice grains.

また、操作パネル40の量設定スイッチ45を所望の値に設定し、白さ設定スイッチ43を「胚芽米」に設定した後、美白米モードスイッチ42及び運転開始・停止スイッチ34をオンすると、精米開始と同時に数秒の間、水分を噴霧して米粒表面の糠分を軟らかくし、胚芽米を精白すると同時に「美白米モード」が開始されることになる。   Further, after setting the quantity setting switch 45 of the operation panel 40 to a desired value and setting the whiteness setting switch 43 to “germ rice”, when the whitening rice mode switch 42 and the operation start / stop switch 34 are turned on, the rice milling is performed. At the same time as the start, water is sprayed for a few minutes to soften the rice grain surface, and the germinated rice is refined and at the same time the “whitening rice mode” is started.

Figure 0006142988
Figure 0006142988

表2は玄米を胚芽米に精白する際に「美白米モード」を追加して実行したときの制御を示す仕様図である。表2において、例えば、量設定が1合の場合は、総精米時間180秒の全区間を通して精米用撹拌軸29が回転数1650rpmで精米が行われる。そして、精米開始と同時に5秒までは水分を噴霧しながら精米が行われ、その後、5秒から180秒までの区間(175秒間)は水分の噴霧なしで研磨されることを示している。また、量設定が5合の場合は、総精米時間300秒のうち、精米開始から60秒までの区間は精米用撹拌軸29が回転数2300rpmで精米が行われ、60秒から300秒までの区間は精米用撹拌軸29が回転数2450rpmで精米が行われることを示している。そして、精米開始と同時に5秒までは水分を噴霧しながら精米が行われ、その後、5秒から300秒までの区間(295秒間)は水分の噴霧なしで研磨されることを示している。このように、玄米を白米に精白する際と異なり、玄米を胚芽米に精白する際は、精米終了前に水分を噴霧するよりも、精米開始と同時に5秒間水分を噴霧しながら精米することにより、胚芽残存率を高めることが可能となる。   Table 2 is a specification diagram showing the control when the “whitening rice mode” is added and executed when the brown rice is refined into germ rice. In Table 2, for example, when the amount setting is 1, the rice milling is performed at the rotational speed of 1650 rpm by the stirring shaft 29 for rice milling throughout the entire section of the total rice milling time of 180 seconds. Then, the rice milling is performed while spraying water up to 5 seconds simultaneously with the start of the rice polishing, and thereafter, the section from 5 seconds to 180 seconds (175 seconds) is polished without spraying water. In addition, when the amount setting is 5 go, out of the total milling time of 300 seconds, in the section from the start of milling to 60 seconds, the milling shaft 29 for milling is polished at a rotational speed of 2300 rpm, and from 60 seconds to 300 seconds. The section shows that the rice milling is performed at the rotational speed of 2450 rpm of the milling shaft 29 for rice milling. Then, the rice milling is performed while spraying water for 5 seconds simultaneously with the start of the rice polishing, and thereafter, the section from 5 seconds to 300 seconds (295 seconds) is polished without spraying water. In this way, unlike when white rice is polished to white rice, when brown rice is polished to germinated rice, it is polished by spraying water for 5 seconds at the same time as the start of rice polishing, rather than spraying water before the end of rice polishing. This makes it possible to increase the germ survival rate.

図2を参照して説明すると、精米が開始されると同時に、5秒間、加湿部7から水分が噴霧される。すなわち、電磁弁14及び噴霧ノズル13が作動し、ノズル13から精米容器26内の米粒に向けて水が噴霧される。このとき、胴割れが生じないよう、あらかじめ加温ヒータ15によって水温が50〜55℃の範囲に保持された温水が噴霧されることになる。水の噴霧量としては、白さ設定スイッチ43を「胚芽米」に設定した場合、原料となる玄米重量に対し、0.4〜0.8%が好ましく、より好ましくは、0.5〜0.7%がよい。噴霧時間としては精米開始直後から5秒間に制限すると、胚芽残存率を高めることができる。   If it demonstrates with reference to FIG. 2, water | moisture content is sprayed from the humidification part 7 for 5 second simultaneously with the start of rice polishing. That is, the solenoid valve 14 and the spray nozzle 13 are operated, and water is sprayed from the nozzle 13 toward the rice grains in the rice mill container 26. At this time, the hot water in which the water temperature is previously held in the range of 50 to 55 ° C. by the heating heater 15 is sprayed so as not to cause the body crack. When the whiteness setting switch 43 is set to “germ rice”, the amount of water sprayed is preferably 0.4 to 0.8%, more preferably 0.5 to 0, based on the weight of brown rice as a raw material. .7% is good. If the spraying time is limited to 5 seconds immediately after the start of the rice polishing, the remaining rate of germ can be increased.

上記のように水分の噴霧が行われると、米粒表面に付着した糠分が軟質化される。そして、精米終了までの間(295秒)精米が継続され、米粒が攪拌されることで研磨作用が生じる。すなわち、米粒同士が相互に擦(こす)れ合って糠分が剥離されるとともに、米粒表面の凹凸がなくなり光沢が生じるようになる。   When moisture is sprayed as described above, the soot adhering to the surface of the rice grain is softened. Then, until the rice milling is finished (295 seconds), the rice milling is continued, and the rice grains are stirred to produce a polishing action. That is, the rice grains are rubbed against each other and the cocoons are peeled off, and the unevenness on the surface of the rice grains is eliminated, resulting in gloss.

[従来の精米工程と美白米モードを追加して実行したときとの比較]
従来の精米工程と美白米モードを追加して実行したときの精米工程とを比較するために、各工程での仕上がり精品の米粒品位を比較・検討した(図6参照)。供試試料としては、平成24年広島県産キヌヒカリを用いた。原料玄米の白度は20.6、水分は13.7%であった。なお、水分の測定には、株式会社ケット科学研究所製の水分計 型式PB1Dを使用し、白度の測定には、同社の玄米・精米白度計 型式C−300−3を使用し、胴割れ粒数、胚芽残存率及び砕米率の測定には、株式会社サタケ製グレインスキャナー RSQI10Aを使用した。
その結果、原料玄米からの白度上昇値を比較すると、美白モードを追加したもののほうが、白度上昇値が1.1乃至3.1ポイント高くなり、光沢が増して白度が上昇したことが分かる。一方で、胴割れ粒数を比較すると、美白モードを追加したもののほうが、胴割れ率が高いことが分かる。これは、精米中の米粒に水分を噴霧することで米粒の内部組織に歪みが生じるためと思われる。しかし、量設定値が3合以上では、従来の精米工程と同等程度の胴割れ率となることが分かった。
[Comparison between conventional rice milling process and whitening rice mode added]
In order to compare the conventional rice milling process with the rice milling process when the whitening rice mode was added, the quality of the finished grain in each process was compared and examined (see FIG. 6). Kinuhikari produced in Hiroshima Prefecture in 2012 was used as a test sample. The whiteness of the raw brown rice was 20.6 and the water content was 13.7%. In addition, the moisture meter model PB1D made by Kett Science Laboratory Co., Ltd. is used for moisture measurement, and the brown rice / milled rice whiteness meter model C-300-3 is used for whiteness measurement. A grain scanner RSQI10A manufactured by Satake Co., Ltd. was used for the measurement of the number of cracked grains, the residual rate of germ and the broken rice rate.
As a result, when the whiteness increase value from the raw brown rice was compared, the whiteness increase value was 1.1 to 3.1 points higher with the addition of the whitening mode, and the gloss increased and the whiteness increased. I understand. On the other hand, when the number of shell crack grains is compared, it can be seen that the one with the whitening mode added has a higher shell crack ratio. This is probably because the internal structure of the rice grain is distorted by spraying water on the rice grain in the polished rice. However, it was found that when the amount set value is 3 go or higher, the cracking rate is comparable to that of the conventional rice milling process.

[従来の胚芽米の精米工程と美白米モードを追加して実行したときとの比較]
上記同様に従来の胚芽米の精米工程と美白モードを追加して実行したときの精米工程とを比較した(図7参照)。
その結果、原料玄米からの白度上昇値を比較すると、美白モードを追加したもののほうが、白度上昇値が0.6乃至1.2ポイント高くなり、光沢が増して白度上昇したことが分かる。一方、胴割れ粒数及び砕米率はほぼ同等であるが、胚芽残存率に関しては、0.5乃至3.7ポイント高くなり、従来の胚芽米の精米工程よりも効果的に胚芽を残せることが分かった。
[Comparison between the conventional rice milling process of germinated rice and the addition of whitening rice mode]
In the same manner as described above, the conventional rice polishing process of germinated rice was compared with the rice polishing process when the whitening mode was added (see FIG. 7).
As a result, when the whiteness increase value from the raw brown rice is compared, it can be seen that the whiteness increase value is 0.6 to 1.2 points higher with the addition of the whitening mode, the gloss is increased and the whiteness is increased. . On the other hand, the number of cracked grains and the broken rice rate are almost the same, but the remaining rate of the germ is 0.5 to 3.7 points higher, and it is possible to leave the germ more effectively than the conventional rice polishing process. I understood.

[集糠部の改良]
図8は、米粒表面から剥離された糠分を吸引するために、集糠部を改良した実施例である。前記特許文献1及び2に開示の従来の家庭用精米機と異なる点は、従来の家庭用精米機では、精米作用は、精米用撹拌軸29の回転による遠心力により玄米を精米容器26へ向けて投げ出すことにより行われる。これにより、玄米から剥離された糠は精米容器26の除糠用多孔壁26aから漏出し、集糠容器25に自然落下することにより集糠が行われる。このような遠心力による投げ出し及び自然落下では、糠切れが悪く、白度が上がらない問題がある。これに対し、図8では筐体2の一側に集糠容器25と連通する外気取り入れ口を穿設するとともに、筐体2の他側に吸引ファン41を介した糠捕集部49を設けた構成である。この糠捕集部49は、精米容器26の除糠用多孔壁26aから漏出した糠を集糠容器25から回収する把手50a付きの糠受け容器50と、該糠受け容器50上部に設置したサイクロン51と、該サイクロン51の空気排出口51aと吸引ファンとの間を連絡する吸引管52と、前記集糠容器25と糠受け容器50との間を連絡する連通管53と、から主要部が構成される。前記サイクロン51の内部には、空気排出口51a近傍に糠除去フィルター54を介在させるとともに、糠除去フィルター54の下方には、円筒部55を形成し、該円筒部55の下方であって、糠受け容器50上部開口部には、円筒部55と相俟(ま)って下方への旋回流を生じさせるテーパー部56を形成する。
[Improvement of concentration section]
FIG. 8 shows an embodiment in which the gathering portion is improved in order to suck the soot separated from the surface of the rice grain. The difference from the conventional domestic rice milling machine disclosed in Patent Documents 1 and 2 is that, in the conventional household rice milling machine, the rice milling action directs brown rice to the rice milling container 26 by the centrifugal force generated by the rotation of the stirring shaft 29 for rice milling. It is done by throwing out. As a result, the koji peeled from the brown rice leaks out from the porous wall 26a for removing the rice milling vessel 26 and is naturally dropped into the collecting vessel 25, thereby collecting the rice. Throwing and natural falling by such centrifugal force has a problem that the flaws are poor and the whiteness does not increase. On the other hand, in FIG. 8, an outside air intake port that communicates with the collection container 25 is formed on one side of the housing 2, and a soot collecting portion 49 is provided on the other side of the housing 2 via the suction fan 41. It is a configuration. The rice cake collection part 49 includes a rice cake receiving container 50 with a handle 50a for collecting the rice cake leaked from the porous wall 26a for removing the rice removal from the rice collection container 25, and a cyclone installed on the upper part of the rice cake receiving container 50. 51, a suction pipe 52 that communicates between the air outlet 51a of the cyclone 51 and the suction fan, and a communication pipe 53 that communicates between the collection container 25 and the basket receiving container 50. Composed. Inside the cyclone 51, a soot removal filter 54 is interposed in the vicinity of the air discharge port 51 a, and a cylindrical portion 55 is formed below the soot removal filter 54, below the cylindrical portion 55. In the upper opening of the receiving container 50, a tapered portion 56 that forms a downward swirling flow in combination with the cylindrical portion 55 is formed.

[吸引なしと吸引ありとの比較]
図9は、美白米モードを実行したとき(吸引なし)と図8の集糠部を駆動したとき(吸引あり)とを比較した結果である。
図9の上下の表を比較すると、白度上昇値は吸引ありのほうが、1.6ポイント高くなり、白度上昇が高くなることが分かった。しかしながら、胴割れ率、胚芽残存率及び砕米率が高くなり、これらの米粒品位の項目は悪い結果となった。
[Comparison between no suction and with suction]
FIG. 9 shows a result of comparison between when the whitening rice mode is executed (without suction) and when the collecting portion of FIG. 8 is driven (with suction).
Comparing the upper and lower tables in FIG. 9, it was found that the whiteness increase value is 1.6 points higher with suction and the whiteness increase is higher. However, the body cracking rate, the germ residue rate, and the broken rice rate increased, and these rice grain quality items gave bad results.

なお、本発明の家庭用精米機は、上記実施の形態に限らず、種々の設計変更が可能である。例えば、水分の添加に通常の水を用いているが、健康によい乳酸菌含有の水溶液や、酵母菌含有の水溶液や、ビタミンEなどを含む水溶液や、γ−アミノ酪酸含有の水溶液などを選択して添加することもでき、仕上がった精品は栄養付加米として家庭で喫食するとよい。   The household rice milling machine of the present invention is not limited to the above embodiment, and various design changes are possible. For example, normal water is used to add water, but a healthy lactic acid bacteria-containing aqueous solution, a yeast-containing aqueous solution, an aqueous solution containing vitamin E, or a γ-aminobutyric acid-containing aqueous solution is selected. The finished refined product should be eaten at home as nourishing rice.

以上説明したとおり、本発明は、精米容器内で精米中の米粒に水分を添加させる加湿部と、該加湿部を制御して所望の精白度と精米量の設定値に応じて水分の添加量及び添加タイミングを決定する制御部とが設けられ、精米開始から一定時間経過後に加湿部から水分が添加され、米粒表面の糠分は軟質化され、米粒が攪拌されることで研磨作用が生じ、糠の除去性能が極めて優れた無洗米に仕上げることができる新規かつ有用な家庭用精米機であることは明らかである。   As described above, the present invention includes a humidifying unit for adding water to the rice grains in the polished rice in the rice milling container, and controlling the humidifying unit to add water according to the desired milling degree and the set amount of the polished rice. And a control unit for determining the addition timing, water is added from the humidifying unit after a certain time has elapsed from the start of the rice milling, the rice cake surface is softened, and the rice grains are agitated to produce a polishing action, It is clear that the rice mill is a new and useful household rice mill that can be made into wash-free rice with extremely excellent mash removal performance.

本発明は、撹拌式の家庭用精米機のほか、撹拌式の家庭用製粉機など適用することが可能である。   The present invention can be applied to an agitating household mill, as well as an agitating household rice mill.
