Description

精米機、精米施設、精米機の運転管理システムRice milling machine, rice milling facility, operation management system for rice milling machine
　本発明は、同一の原料玄米を搗精する場合に得られる米粒の搗精度合の品質のバラツキを防止することができる精米機、精米施設、及び精米機の運転管理システムに関する。また、リアルタイムで高精度な歩留制御を行うことができる精米機に関する。 The present invention relates to a rice milling machine, a rice milling facility, and an operation management system for the rice milling machine that can prevent variations in the quality of the rice grains obtained when the same raw material brown rice is milled. The present invention also relates to a rice milling machine capable of highly accurate yield control in real time.
　従来、精米機で玄米を搗精する際、精白室の排出口に設けられる圧力蓋の圧迫度や精白ロールの回転数等を制御して、所定の白度や精白度の米粒に加工する技術が知られている（例えば、特許文献１，２を参照。）。 Conventionally, when brown rice is polished with a rice polishing machine, there is a technology that controls the degree of pressure of the pressure lid provided at the discharge port of the polishing chamber and the rotation speed of the polishing roll, etc., to process rice grains with a predetermined degree of whiteness and polishing. known (see, for example, Patent Documents 1 and 2).
　前記精米機は、搗精後の米粒の白度や精白度を基準値と比較しながら、前記圧力蓋の圧迫度や前記精白ロールの回転数等をフィードバック制御し、米粒の搗精度合を所定の品質に保つことができる。 The rice milling machine feedback-controls the degree of pressure of the pressure lid and the rotation speed of the milling roll while comparing the degree of whiteness and degree of polishing of the rice grains after polishing with a reference value, thereby adjusting the degree of polishing of the rice grains to a predetermined quality. can be kept in
　前記精米機では、運転開始時に白度や精白度等の基準値を設定する。オペレータが搗精後の米粒の品質をオペレータの目視や手持ちの白度計等で検査する。そして、品質に問題がある場合には、前記基準値を上下に変更するなど搗精後の米粒の白度や精白度等を調整した上で、製品の生産を行っている。 In the rice milling machine, standard values such as whiteness and degree of polishing are set at the start of operation. The operator inspects the quality of the rice grains after polishing with his/her own eyes or with a hand-held whiteness meter. If there is a problem with the quality, the standard value is changed up or down to adjust the degree of whiteness or polishing of the grains after polishing, and then the product is produced.
　オペレータの目視や白度計等による検査には個人差がある。そのため、例えば産地、品種、産年が同一の玄米であっても、オペレータが異なる場合には、搗精後に得られる米粒の搗精度合に品質のバラツキが生じる場合がある。 There are individual differences in the operator's visual inspection and inspection with a whiteness meter. Therefore, even if brown rice is produced in the same place of production, variety, and year of production, if the operator is different, the quality of the rice grains obtained after polishing may vary in terms of the degree of polishing.
　また、精米機で玄米を搗精するに際し、搗精前後における米粒の重量の変化に基づいて歩留制御を行うことが知られている（例えば、特許文献３を参照。）。 In addition, it is known that when brown rice is polished by a rice polishing machine, yield control is performed based on the change in the weight of rice grains before and after polishing (see Patent Document 3, for example).
　特許文献３に記載された発明は、精米機の前後に計量装置を設け、各計量装置で計量される米粒の重量値の変化に基づいて歩留値を算出し、該歩留値を基準値と比較して前記精米機の抵抗蓋の抵抗力を調節するものであり、精米機の歩留制御をリアルタイムで行うことができる。 In the invention described in Patent Document 3, weighing devices are provided before and after the rice milling machine, the yield value is calculated based on the change in the weight value of the rice grains weighed by each weighing device, and the yield value is used as the reference value. It is to adjust the resistance force of the resistance lid of the rice milling machine compared with the above, and the yield control of the rice milling machine can be performed in real time.
　特許文献３に記載された発明では、精米機の前後に設けられる各計量装置において米粒の重量値を瞬時に計量する必要があるが、短時間での計量は振動等の影響を受けやすく誤差が大きいために、正確な重量値を計量することが難しい場合がある。 In the invention described in Patent Document 3, it is necessary to instantaneously measure the weight of rice grains in each weighing device installed before and after the rice mill. Due to their large size, it can be difficult to weigh an accurate weight value.

　そこで、本発明は、同一の原料玄米を搗精する場合に得られる米粒の搗精度合の品質のバラツキを防止することができる精米機を提供することを目的とする。 Therefore, it is an object of the present invention to provide a rice milling machine that can prevent variation in the quality of the rice grains obtained when the same raw material brown rice is polished.
　また、本発明は、複数の精米機を備える精米施設であって、前記複数の精米機で同一の原料玄米を搗精する場合に得られる米粒の搗精度合の品質のバラツキを防止することができる精米施設を提供することを目的とする。 Further, the present invention is a rice milling facility equipped with a plurality of rice milling machines, and can prevent variations in the quality of rice grains obtained when the same raw material brown rice is milled by the plurality of rice milling machines. The purpose is to provide facilities.
　さらに、本発明は、複数の精米機の運転管理を行う精米機の運転管理システムであって、前記複数の精米機で同一の原料玄米を搗精する場合に得られる米粒の搗精度合の品質のバラツキを防止することができる精米機の運転管理システムを提供することを目的とする。 Furthermore, the present invention is an operation management system for a rice mill that manages the operation of a plurality of rice mills, and is characterized in that when the same raw material brown rice is polished by the plurality of rice mills, the quality of the rice grains that are polished is uniform. An object of the present invention is to provide an operation management system for a rice mill that can prevent
　また、本発明は、リアルタイムで高精度な歩留制御を行うことができる精米機を提供することを目的とする。 Another object of the present invention is to provide a rice milling machine capable of highly accurate yield control in real time.
　上記目的を達成するため、本発明の実施の形態では、
　米粒の搗精度合が所定の品質となるよう搗精度合調節手段を制御する制御部を備える精米機であって、
　米粒の搗精度合を検出可能とする検出手段を備え、

　前記記憶手段に記憶登録され、前記原料玄米の原料情報及び前記目標搗精度合により特定される前記制御情報に基づいて、原料玄米の搗精加工を開始可能とする。 In order to achieve the above object, in the embodiment of the present invention,
