technical field

The invention relates to the technical field of poultry egg processing, in particular to a method and a shell-cutting hole-cutting machine for salted eggs.

Background technique

China is the largest consumer and trader of poultry eggs. With the improvement of living standards, people's needs for eggs are becoming more and more diverse. In the processing of egg products, it is sometimes necessary to open holes in eggshells, especially raw eggs, to pour food or seasonings into the holes, or to separate egg whites or egg yolks from the holes. At present, most of the egg opening devices on the market are simple hand-held opening devices. The same part of the egg shell is repeatedly knocked by a cylindrical device to break the egg shell along the circle, so as to achieve the purpose of opening holes.
