<p>A device (1) and method for dehydration of a product, especially useful for reducing wetness of leaf vegetables such as parsley, the device (1) comprising a dehydration cell (4) having a product inlet (60), a product outlet (62), and a bottom plate (5) with a plurality of apertures (6-10) forming gas permeable open areas. The apertures (6-10) are arranged such that the open areas gradually decrease in a direction between first and second ends (25, 26) of the plate (5) along the plate's width such that, when gas is forced into the cell (4) through the plurality of apertures (6-10), a plurality of respective separate gas jets (16-20) eject upwardly from the plate (5) with a gas flow rate decreasing in said direction along the plate thus creating a global directional circulation (30-39) of the gas throughout the cell (4) and a plurality of local circulations (70-72, 76-78) of said gas inside the cell (4).</p> |
