INTERMITTENT DRYER FOR GRANULAR POLYMER MATERIALS WITH ADAPTIVE VOLUME OF DRYING CHAMBER Russian patent published in 2014 - IPC F26B17/12 

FIELD: chemistry.

SUBSTANCE: intermittent dryer for granular polymer materials with adaptive volume of the working chamber comprises a feed hopper, an upper gate, a working chamber, a lower gate and a receiving hopper. In order to feed the material to be dried, the working chamber is made of telescopic perforated elements, wherein the working volume of said chamber is bounded by lower and upper bayonet locks, having an angle β, the value of which is 3…5° more than the natural angle of repose of the granular polymer materials.

EFFECT: providing uniformity of the dried material in terms of moisture content on the entire height of the layer.
