Abstract: A system for continuously making-down a dry powder material is provided. The system may include a liquid supply system, a material feed system, a vessel, a filter, and an agitator. The vessel may receive a continuous supply of liquid from the liquid supply system and a continuous supply of dry powder from the material feed system. The liquid and material may be discharged continuously from the vessel. A filter may sealingly extend across the outlet to filter the solution exiting the vessel. The filter may include an upstream surface in contact with the inner volume of the vessel. The agitator may be disposed within the vessel and may be configured to agitate the contents of the vessel. The agitator may include a wiping member configured to contact the upstream surface of the filter while agitating the contents.
