Egg Shell Dryer

Sanitizing and drying egg shells.


The °Celsius Egg Shell Dryer is part of a continuous industrial process, whereby the shells of recently broken eggs are sterilised. Because the shells are heated to approximately 130 degrees during this sanitization process, they are dried at the same time. The result is a germ-free, fine-grained and valuable lime product with a maximum moisture content of 1%. This end product can be used as a soil improver or as lime for the feed or cement industry, whereas untreated shells are often very difficult and expensive to dispose of. It also means odour nuisance is a thing of the past.


°Celsius can supply 3 different installations with a processing capacity of 500, 1000 or 1500 kilograms of shells per hour. If required °Celsius can develop installations with a lower or higher capacity fully adjusted to your company. Users who have purchased an Egg Shell Dryer soon ask themselves how they managed without one for so long. After all an Egg Shell Dryer is not only an investment which is compulsory under European Regulation EC 1774/2002 but also a machine that converts a waste stream into a useful raw material, talk about cradle to cradle! An extensive reference list is of course available on request.
