Abstract
The present invention relates to a novel desiccant powder and its use for the drying of solid substrates wetted by an aqueous or oily liquid such as, in particular, grains or seeds having undergone a coating or surface film-forming treatment. According to the invention, this desiccant powder contains at least 50% by weight of absorbents with respect to the toal weight of the said powder, being preferably available in the form of particles having a mean diameter less than about 100.mu., the said absorbents being constituted of at least one aluminosilicate, in particular mica, to at least 25% by weight with respect to the total weight of the said absorbents. This powder makes possible, in particular, the drying of colored grains or seeds.
