<p>A process and a plant for continuously drying products with the use of increasing temperatures towards the end of the drying process, the drying process using the so-called multiple transverse stirring. There is admitted in the zone of completion of the drying process a first air flow (4), the additional or major air flow being admitted in a zone (5) where the product has lost most of its moisture content, the first air flow being heated at 8(III) to a high temperature, the additional air flow (5) being heated to a mean temperature (11) and the entire air flow being subjected to heat inputs 8(I) at a mean temperature derived from at least one heat pump (13) The invention reduces the heat input required for such a process.</p> |
