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.

Abstract: A stirring blade unit includes a perforated cylinder formed around the an internal stirring blade so as to be rotated together with the stirring shaft. The perforated cylinder has perforations which are approximately 30 to 50% of the area of the top and bottom surface of the perforated cylinder. The internal stirring blade unit uses a discharge type stirring blade unit used for gas-liquid mixing of a general fermentation tank.

Due to this hitting of the gas-liquid flow against the perforated cylinder, the pressure of the flow is changed significantly to refine the gas bubbles so that the gas absorption property is improved. The stirring blade unit is suitable for gas-liquid mixing necessary for such as, fermentation, aeration, and reaction (hydrogenation and oxidation) tanks.
