GRANULE SPRAYING APPARATUS

摘要

PROBLEM TO BE SOLVED: To easily recover a test chemical that is fed from a feed part and discharged, to have no recovery loss and to perform a precise measurement when a feed amount of granule is measured in a granule spraying apparatus equipped with the feed part for feeding granule and a diffusion blade for diffusing discharged granule below an outlet for discharging granule fed from the feed part. SOLUTION: The granule spraying apparatus includes a mode change means 110 for switching between a spray mode for rotating the diffusion blade to spray the granule while driving the feed part and feeding the granule and a measurement mode for collecting the granule discharged downward from the outlet by stopping the diffusion blade and driving the feed part.
