The apparatus for drying organic materials such as for example brown coal has a space (5) maintained under a pressure exceeding atmospheric pressure, the material to be dried being supplied to the upper end (12) of said space and the dried material being discharged from the lower end (20) of said space. Between the supply opening (12) and the discharge opening (20) there are provided obliquely arranged sieves (2, 6) and water-impermeable collecting spaces for the water separated on the sieves. The collecting spaces (3, 7) for the water separated on the sieves are connected with drain channels (9, 10), and several sieves (2, 6) are arranged one above the other in the manner of cascades, the lower edge of one sieve being located above an uppermost area of the following sieve (2, 6) as seen in flow direction (FIG. 1). |
