Abstract
Provided is a method that enables sufficient separation of an egg shell and an egg shell membrane from each other even in a small scale, using a simpler configuration than conventional methods. The method for separating an egg shell and an egg shell membrane from each other includes a step of adding an egg shell with an egg shell membrane attached thereto to a swirling flow of an alkaline solution.

A method for separating an egg shell and an egg shell membrane from each other, comprising
- a step of adding an egg shell with an egg shell membrane attached thereto to a swirling flow of an alkaline solution,
- wherein the alkaline solution has a pH of 10 to 14 and is an aqueous calcium hydroxide solution.
A method for separating an egg shell and an egg shell membrane from each other, using an apparatus for separation of egg shell membrane, the apparatus comprising:
- a bottomed cylindrical container with an opening on the top;
- an alkaline solution supplying part positioned near the bottom of the container side;
- and
- an egg shell feeding part positioned near the center of the opening on the top of the container;
- wherein the method comprises steps of:
- adding an alkaline solution from the alkaline solution supplying part to generate a swirling flow of the alkaline solution in the container;
- adding an egg shell with an egg shell membrane attached thereto from the egg shell feeding part;
- and
- collecting an egg shell membrane suspended in the swirling flow of the alkaline solution,
- wherein the alkaline solution has a pH of 10 to 14 and is an aqueous calcium hydroxide solution.
An apparatus for separating an egg shell and an egg shell membrane from each other, comprising:
- a bottomed cylindrical container capable of containing an egg shell with an egg shell membrane attached thereto and an alkaline solution;
- an alkaline solution supplying part positioned near the bottom of the container and opened toward the container in a direction enabling the formation of a swirling flow of the alkaline solution in the container;
- and
- a hollow egg shell feeding part positioned above and within the container, and coaxially with the center of the swirling flow of the alkaline solution,
- wherein the alkaline solution has a pH of 10 to 14 and is an aqueous calcium hydroxide solution.
