【発明の詳細な説明】 「産業上の利用分野」 この発明は、循環式全自動精米装置、とくに高品質の高
度精白を必要とする醸造用精米装置の米重量算出方法に
関する。TECHNICAL FIELD The present invention relates to a method for calculating a rice weight of a circulation type fully automatic rice polishing apparatus, particularly a brewing rice polishing apparatus that requires high-quality advanced whitening.
「従来の技術」 米を精白すると、精白度（即ち精白中の米重量と張込米
重量との100分比）が進につれて、米の内部の層が次々
に表面に表れてくる。そこで前記のような高品質、高度

なるよう、精米機を制御する必要がある。“Prior Art” When whitening rice, the inner layers of rice appear on the surface one after another, as the degree of whitening (that is, the ratio of the weight of rice in the whitening to the weight of the laid rice) increases. Therefore, in order to perform high quality and advanced whitening as described above, the polishing conditions, that is, the rotation speed of the whitening roll spindle of the rice polishing machine, the load current value of the whitening roll drive motor, the resistance lid opening, It is necessary to control the rice milling machine to obtain the most suitable value for the property.
そしてこの制御にあたって、その基準となる米重量の検
出が、正確に行なわれなければならないのは勿論であ
る。In addition, in this control, it is needless to say that the reference weight of rice must be accurately detected.
ところで、この精白度を検出する方法として、従来から
精米タンクにロードセルなどの重量検出装置を設けるの
が一般である。By the way, as a method of detecting the degree of whitening, it has been customary to provide a weight detecting device such as a load cell in a rice polishing tank.
「発明が解決しようとする問題点」 しかしながら、精米タンクに設けたロードセルなどの米
重量検出装置は、精米タンク内の米重量のみを検出する
ものである。従って精米タンクの重量を検出しても、米
重量は正確に検出することができない。なぜなら。精米
中では、精米タンク以外の受箱、昇降機など、精米タン
ク外の精米装置の各部分に米が分散して存在しているか
らである。[Problems to be Solved by the Invention] However, a rice weight detection device such as a load cell provided in a rice polishing tank detects only the weight of rice in the rice polishing tank. Therefore, even if the weight of the rice polishing tank is detected, the rice weight cannot be accurately detected. Because. This is because, during rice polishing, rice is dispersed and present in each part of the rice polishing device outside the rice polishing tank, such as an inbox and an elevator other than the rice polishing tank.
このため循環式全自動精米装置では、精米中に精米タン
ク外に分散する米の重量を予測して、精白度を演算部
（CPU）で演算することも可能である。しかし、精米タ
ンク外に分散する米の量は、刻々と変化するため、やは
り正確な精白度が求められない欠点があった。For this reason, in the circulation-type fully automatic rice polishing apparatus, it is possible to predict the weight of the rice dispersed outside the rice polishing tank during the rice polishing and to calculate the whitening degree by the calculation unit (CPU). However, since the amount of rice dispersed outside the rice polishing tank changes from moment to moment, there is a drawback that an accurate degree of milling is not required.
