according to the size of the egg product to be separated, the size of the leakage liquid seam 307 is adjusted to meet the requirement of quickly leaking egg white without leaking yolk, an air extractor is operated to extract air to the adsorption cavity 60 through an air pipe 601 to generate negative pressure to the adsorption cavity 60, the egg white and yolk mixed liquid without shells flows into a V-shaped groove of the separation tank 30 through a feed hopper 20, the egg white and yolk mixed liquid slides towards the lower end of the separation tank 30 along the V-shaped groove, egg white liquid far away from a yolk membrane in the egg white mixed liquid leaks from the leakage liquid seam 307 to an egg white collection plate 404 and then flows into an egg white collection box 401, yolk software cannot flow into the egg white collection plate 404 below the separation tank 30 through the leakage liquid seam 307 under the wrapping protection of the yolk membrane, after separation of the leakage liquid seam 307 and the adsorption cloth strip 70, the yolk together with egg white liquid and yolk frenulum adhered on the yolk membrane slide onto an annular mesh 501 of a membrane breaking mechanism, a pointed object 506 on the annular mesh plate 501 breaks the yolk membrane to enable the yolk membrane and egg white liquid adhered to flow out through meshes of the egg white collection box 405 which are smaller than the yolk membrane 5011 under the egg white membrane and the egg white collection box 405, and the egg white liquid can not flow into the egg white collection box 405 completely, and the egg white collection box 405 can flow into egg white collection box 405.
When the vitelline membrane and the vitelline frenulum gathered on the annular screen 501 hinder the vitelline liquid from flowing to the yolk collecting plate 405, the driving motor 505 drives the driving shaft 503 to rotate so as to drive the driving sprocket 5031 to rotate, the chain 502 meshed with the driving sprocket 5031 drives the flexible annular screen 501 to rotate, and as the driven sprocket 5041 is positioned in the cleaning tank 403, when the annular screen 501 rotates to pass through the cleaning tank 403, the cleaning brush 4031 in the cleaning tank 403 brushes the vitelline membrane, the egg white and the vitelline frenulum on the annular screen 501 into the water body in the cleaning tank 403.
Compared with the existing yolk-egg white separation device, the yolk membrane, egg white liquid adhered to the yolk membrane, yolk frenulum and the like are separated from the yolk liquid through primary separation of the separation tank 30 and secondary separation of the membrane breaking mechanism, so that the complete separation of the egg white liquid and the yolk liquid is realized, the purity of the yolk liquid for extracting lecithin is improved, the extraction rate of the lecithin is further improved, the use amount of the solution and the extract liquid is reasonably determined, the resource waste caused by excessive use of the solution and the extract liquid is avoided, and the lecithin purity is reduced.
The above are merely examples of the present invention, and common general knowledge of known specific structures and characteristics in the schemes is not described herein. It should be noted that, for those skilled in the art, without departing from the structure of the present invention, several changes and modifications can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicability of the patent. The scope of the claims of the present application shall be determined by the contents of the claims, and the description of the embodiments and the like in the specification shall be used to explain the contents of the claims.
