Abstract

An improved hydration method heat avoids clogging for the transfer, solvation, and storage of dry particulate matter for a sealed solvation hopper chamber in combination with a liquid driven eductor and equipped to be connected to a storage container. Specifically, the improvement resides in the steps of reducing the flow of the dry particular matter and flushing the solvating hopper with water automatically at predetermined periodic intervals.
