Abstract

Substances are particularly polyamides in the form of granules or chips. Apparatus consists of a hollow rotating vessel with cooled surfaces, its axis being slightly inclided in the horizontal in order to promote a flow of the granules to be treated through the apparatus. Its internal structure encourages maximum heat transfer with the walls, and cooling is effected at least in part by a water spray on the outside. The apparatus may be filled with inert gas and operates so as to maintain the humidity of the particles unchanged. - The advantages of the apparatus is that it can be inserted in a continuous drying and treatment circuit.
