The Celsius Eggshell Dryer (ESD) has been specially developed to dry broken eggshells in one continuous process, producing an end product that is germ-free, fine-grained and high-quality lime with a moisture content of no more than 1%.
Egg shells are classified in the industrial sector as animal by-products category 3 waste for which the producer is responsible. Disposing of or reusing them can be a laborious or costly exercise. This despite the fact that the shells are 100% recyclable and reusable, and there are some excellent uses for eggshells in the market.
Storing, transporting and disposing of untreated egg shells is often very difficult and involves considerable costs. Furthermore, eggs shells can cause an odour problem. Drying them immediately with the help of an eggshell dryer makes this a thing of the past, and adds value to your waste.
The basis of the eggshell dryer is a screw heat exchanger with a trough-shaped casing and a double-walled screw and casing. The elevation angle is 15 degrees. Various control valves regulate the incoming and outgoing thermal oil for the screws and the frame.
The following components are optionally available as add-ons to the basic egg shell dryer:
– Thermal gas-fired oil boiler
– Air extraction/wet scrubber
– Inclined screw conveyor systems
– Crushers
– Ozone injection system for odour reduction
– Storage bunkers
– Various connecting screw conveyor systems
The ESD is available in capacities of 500, 1000 or 2000 kilograms of dry shells per hour.
The egg shells reach a temperature of about 110 degrees during the drying process. This means that they are all hygienised simultaneously. The ESD thus complies rigorously with European Regulation EC 1774/2002, in which a Category 3 waste product is upgraded to a valuable end product for trading as a soil improver, or as lime for animal feed or the cement industry, for example.
