After the process is completed, the yolk becomes a dark green, cream-like substance with a strong odor of sulfur and ammonia, while the white ...
Then the ground eggshell is placed in a separate vessel where air is injected into the water flow. The air and water mixture causes the lighter component (protein membrane) to float and the heavier (calcium carbonate eggshells) to sink. This unit recovers 96% of eggshell membrane and 99% of eggshell calcium carbonate in two hours. [10]
