WIPO Patent Application WO/2004/046629
Kind Code:

Abstract:
The invention relates to a method for drying a wet product by convection. The inventive method consists in introducing a product to be dried (3) in to a dryer containing a hot drying gas (12) which absorbs water from the product during drying and from which the absorbed water is extracted by condensation. In order to reduce energy consumption for said drying method and to carry out an efficient sanitation of the dried product and respect ecology, said dried product (3) is passed through at least one drying stage (4, 5) where the drying gas (12) circulates in a closed circuit, condensation heat occurs in said drying stage and is used for heating the drying gas (12) in at least one next drying stage (7, 9).
