Abstract

A method for processing unseparated egg shells includes placing unseparated egg shells in a separation tank containing fluid, applying cavitation to the unseparated egg shells in the fluid to thereby separate the egg shell membranes from the egg shells, and recovering the egg shell membranes. An apparatus for processing unseparated egg shells includes a separation tank for holding a fluid, a recirculating loop operatively connected to the separation tank, and at least one submersible mixer in the recirculating loop to recirculate the fluid and egg shell membranes and egg shells within the fluid. The apparatus further includes a membrane collection conveyor for conveying egg shell membranes from the separation tank and a shell conveyor positioned beneath the separation tank for conveying egg shells away from the separation tank.
