Abstract: カントリーエレベータで超低温貯蔵を行った際の夏季におけるサイロ内壁付近の穀温上昇や内壁付近と中心部の穀温差が品質に与える影響を明らかにするため, 貯蔵終了時のサイロ内各部の籾の品質測定をするとともに, 排出時に約10tごとに籾を採取して品質を測定した。その結果, 夏季の穀温上昇や穀温差が品質に与える悪影響はないことが確認された。カントリーエレベータでの超低温貯蔵による籾貯蔵技術は, 寒冷地の自然環境を利用した米の貯蔵技術として確立した。
The temperature of the rough rice near the inner silo wall gradually increased in spring and summer, whereas that of the rough rice in the center of the silo remained below ice point. The effect of this difference in rough rice temperatures in the silo on rice quality was investigated. There was no deterioration in the quality of rough rice near the silo wall, and the quality of the rough rice unloaded from silo after storage was uniform. These results indicate that there was no significant effect of the difference in grain temperatures in the silo on rice quality. The technique for storing rough rice at a temperature below ice point, i. e., super-low-temperature storage, at country elevators in cold regions using natural energy in winter was finally developed.
