That is, the load current value of the main motor, the flow rate of rice flowing through the polishing room,
It is necessary to control the optimum conditions according to the degree of whitening.
この制御は、個々の酒造業者の特色を発揮できるよう、
もっぱら精米士の勘と経験とによって行われていたが、
現在では自動制御で行われるようになっている。This control allows the individual brewers to display their unique characteristics.
It was done mainly with the intuition and experience of a rice miller,
Nowadays, it is automatically controlled.
前記制御のうち、精白室内の米流量の制御は、精白され
た米の形状を一様にするため、即ち精白された米の表面

供給調節装置」がこれである。As one of the methods for controlling the rice flow rate, there is a method of adjusting the opening of the grain feeding valve irrespective of the load current value of the main motor according to the progress of the whitening degree or at regular intervals. It was For example, this is the "supply adjusting device for grain refiner" described in Japanese Patent Publication No. 56-41304.
又、いま一つの最も便利な方法として、主モータの負荷
電流値の変動を検出して抵抗蓋の開度を調整する方法が
あった。Another most convenient method is to detect the fluctuation of the load current value of the main motor and adjust the opening of the resistance lid.
「発明が解決しようとする問題点」 ところが前者では、「きしみ」などによる精白室の内圧
の変化に対応して、米流量を調整することができないた
め、高品質の精白が行えない欠点があった。"Problems to be solved by the invention" However, the former has the drawback that high-quality whitening cannot be performed because the rice flow rate cannot be adjusted in response to changes in the internal pressure of the whitening chamber due to "squeaking". It was

ない米が精白室へ流入する。For example, if the load current value fluctuates and exceeds the indicated value,
The opening of the resistance lid increases beyond the allowable range, and rice is about to be discharged from the discharge opening where the resistance lid is installed. When the opening of the resistance lid that fluctuates is detected and the detected value and the indicated value are compared and the grain feeding valve opening control device is activated, the grain feeding valve is closed more and less rice is produced from the rice polishing tank. It flows into the polishing room.
この結果、負荷電流値が減少して抵抗蓋の開度を許容範
囲内に納める。従って、精白室の米流量が安定する。As a result, the load current value is reduced and the opening of the resistance lid is kept within the allowable range. Therefore, the rice flow rate in the polishing room becomes stable.
「効果」 負荷電流が変動した場合、即ち精白ロールの負荷が変動
した場合にも、給穀弁と抵抗蓋とが協同して作動するこ
とにより、精白室の米の流れを安定にして、高品質の精
米を行うことができる。"Effect" Even when the load current changes, that is, when the load of the whitening roll changes, the grain feeding valve and the resistance lid work in cooperation to stabilize the flow of rice in the whitening chamber and increase the Can do quality rice polishing.
又、抵抗蓋の開度を指示することにより米流量を容易に
制御できる。Further, the rice flow rate can be easily controlled by instructing the opening of the resistance lid.
