  • Patent number: 10676380
    Abstract: A method of removing food soils from a recirculated washing solution includes adding a flocculating agent to the recirculated washing solution and separating the particulates from the recirculated washing solution using a hydrocyclone. The flocculating agent causes a portion of the food soils to combine into particulates having a higher density.
