Abstract: The present invention is directed to a tickler impeller and agitation system for use in stirred slurry reactors and storage tanks. The tickler impeller when mounted on a shaft is effective for providing an inward and downward swirl in a slurry medium which directs solids suspended in the slurry towards the bottom of the tank and towards the shaft on which the impeller is mounted. Directing solids suspended in a slurry downwards and towards the center of the tank rather than pushing those solids away from the center reduces solid deposits on the side of the tank, facilitates draining of the tank, and reduces nozzle starving and pump starvation.
