Abstract
A method for treating manure including the drying of manure by displacing water out of the manure by a carrier liquid, extracting the carrier liquid by evaporation and purifying the carrier liquid vapor for re-use, wherein fats originally present in the manure are released as manure fat, by burning the manure fat in a controlled manner and at least partially using energy thereby released in the process.
Claims6
A method for treating manure consisting essentially of the steps of:
- a) drying manure by displacing water out of said manure by a carrier liquid;
- b) simultaneously extracting fat from said manure with the same carrier liquid;
- c) removing the carrier liquid through evaporation to release fats originally present in the manure as manure fat and purifying said carrier liquid for reuse;
- d) burning the manure fat obtained in step c) in a controlled manner in a burning device which comprises heat transfer means, said means transferring heat released during the burning to a heat transporting medium;
- and
- e) at least partially using energy transferred to the heat transporting medium in the method for treating manure.
