ABSTRACT:
The present invention includes a process for separating food particles of different specific gravities. The process includes providing a feedstock of the food particles, providing a feedstock of diatomaceous earth and water having a specific gravity effective for particles to float or sink; adding the slurry and separating the floating food particles from the sinking food particles; dewatering the food particles and collecting the water; extracting the diatomaceous earth from the slurry and re-using the diatomaceous earth in the process.
