Nothing is wasted,
everything is converted

Using centrifugation broken or unincubated eggs provide eggshells and also a residual liquid known as the technical albumen. Ovoconcept offer upgrading procedures for these by-products.

For eggshells from hatcheries and breakers two techniques may be implemented:
- sanitisation using a thermal process used to obtain carbonates destined for use in animal nutrition,
- sanitisation by a lime-based mixture for the manufacture of soil improvers.

Drying the technical albumen

Ovoconcept has designed a range of low capacity box dryers that may be used to dry the technical albumen derived from eggshell centrifugation and thus produce egg powder for animal feed, for a coherent investment.

This hygienisation process provides added-value to a by-product that is too often neglected in the poultry breeding industry.

Eggshell drying

Firstly, eggshell volume is reduced by centrifugation. Then the eggshell fragments are conveyed to a dryer that dehydrates, sanitises and reduces the eggshells into powder. The eggshell powder derived from the dryer is conveyed to a silo for storage.

The calcium carbonate obtained in this manner can be upgraded with fertiliser or animal feed manufacturers.
