<p>A method of drying particle material in a bed under pressure by indirect heating. The method according to the invention is carried out so that the steam driven off from the material is superheated with heat of a higher temperature, that the steam is passed through the material bed, which is advanced slowly. The steam leaves the bed at a low speed, thereby preventing greater material particles from following along with the steam from the bed. The steam heat is recovered in a manner known per se. </p> |
