SILO, AND OPERATING METHOD OF THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a silo which can avoid occurrence of the fixation and bridging of a stored article to the internal wall of the storage tank at storage over a long period of time, and can suppress the variation in characteristics of the stored article.SOLUTION: A silo 10 includes: a storage tank 11; a throwing-in mechanism 13 which throws an article A to be stored into the storage tank 11; a discharging mechanism 20 which discharges the stored article from the storage tank 11; and a circulating mechanism 24 in which the stored article A is discharged from the storage tank 11, and thrown into the storage tank 11 again. The circulating mechanism 24 includes: the throwing-in mechanism 13; the discharging mechanism 20; and a circulating-carrying path 25 which carries the stored article A discharged from the discharging mechanism 20 to the throwing-in mechanism 13. The discharging mechanism 20 includes a path-switching mechanism 23 which switches whether the stored article A discharged from the storage tank 11 is carried to a discharging path 22 on the outside of the system or is carried to the circulating-carrying path 25.
