GRANULAR WATER-ABSORBENT FILLING METHOD AND GRANULAR WATER-ABSORBENT SAMPLING METHOD

摘要

The present invention is a granular water-absorbent filling method involving a filling process for filling a filling container (16) with a granular water-absorbent and a vibration process for vibrating the filling container (16) from the outside of the filling container (16), said vibration process being performed at least once during the period between the start and the end of the filling process, wherein the vibration conditions during the vibration process satisfy conditions (a) and (b) described below. (a) Vibrations of a vibrating body (10, 12) in contact with the filling container (16) have vertical components, and the vibration angle is in the range of 90°±30°. (b) Settings for the total amplitude of the vibrating body (10, 12) under no load and the vibration frequency under no load satisfy formula (1-1) and formula (2), or formula (1-2) and formula (2).
