The invention discloses an efficient crushing and separating method for eggshells and shell membranes obtained by incubation and
hatching of
hatching eggs of poultry. The efficient crushing and separating method comprises the following step: performing suffumigating,
drying, primary crushing, vibration screening, electric windwill separation and the like on a complete
eggshell (including inner and outer
layers of shell membranes) obtained by incubation and
hatching. The method is high in crushing and separating efficiency, and the purity of obtained products, i.e.
eggshell powder and shell membrane
powder, is 98 percent or above, and the
moisture content is less than 8 percent; the obtained products are free of
pathogenic bacteria, nontoxic, harmless,
pollution-free and safe; furthermore, the natural attributes of the eggshells and shell membranes which are obtained by incubation are retained, and the products meet the feed level standard; and the method is suitable for
batch processing of breeding poultry incubation fields of different scales, and the eggshells and the shell membranes can be separately used or combined for use so as to develop the breeding value of the
nutrition and the functionality of the eggshells and the shell membranes, improve the productivity of the poultry and the
disease resistance of
livestock, realize reuse of complete
eggshell resources obtained by the incubation and reduce the
pollution to the environment.
